NEW QUESTION # 13
Which TWO statements about the Oracle Cloud Infrastructure (OCI) File Storage Service are accurate?
- A. Customer can encrypt data in their file system using their own Vault encryption key.
- B. Customer can encrypt the communication to a mount target via export options.
- C. Communication with file systems in a mount target is encrypted via HTTPS.
- D. File systems use Oracle-managed keys by default.
- E. Mount targets use Oracle-managed keys by default.
Answer: A,D
Explanation:
File systems use Oracle-managed keys by default. Customer can encrypt data in their file system using their own Vault encryption key. The explanation is that File Storage Service encrypts all data at rest using AES-256 encryption algorithm. By default, File Storage Service uses Oracle-managed keys to encrypt and decrypt data. However, you can also use your own Vault encryption key to encrypt data in your file system. To do so, you need to create a key in Vault and associate it with your file system when you create or update it.
NEW QUESTION # 14
When defining a query for metric data in Monitoring, which field provides the time window for aggregatingmetric data points plotted on the metric chart?
- A. Interval
- B. Dimension
- C. Statistic
- D. Namespace
Answer: A
Explanation:
Explanation
Interval is the field that provides the time window for aggregating metric data points plotted on the metric chart. Interval is a parameter that specifies how often metric data points are collected and aggregated by the Monitoring service. For example, an interval of 5 minutes means that metric data points are aggregated every 5 minutes and displayed on the chart. The other options are not fields that provide the time window for aggregating metric data points, but rather other parameters that define the metric query. References: [Interval]
NEW QUESTION # 15
As a network architect you have deployed a public subnet on your Virtual Cloud Network (VCN) with this security list:
You have also created a network security group (NSG) as shown in the table here, and assigned it to your bastion host:
You have confirmed that routing is correct but when you SSH to the VM from your home over the Internet you are unable to connect.
What could be the problem?
- A. Internet traffic should be allowed only on the NSG.
- B. SSH traffic is not allowed in the security list nor on the NSG from the Internet.
- C. Public subnet does not have a route rule to the Internet Gateway.
- D. User will be able to SSH to the VM from the Internet as SSH is open on the NSG.
Answer: B
Explanation:
SSH traffic is not allowed in the security list nor on the NSG from the Internet is the correct answer. This is because the security list only allows ingress traffic from 10.0.0.24 on port 22, and the NSG only allows ingress traffic from 10.0.0.0/16 on port 22. Neither of them allows ingress traffic from 0.0.0.0/0 (the Internet) on port 22, which is required for SSH access. The other options are not correct, as they do not explain why SSH access is not possible. Reference: [Security Lists], [Network Security Groups]
NEW QUESTION # 16
What should be created before provisioning an Oracle Cloud Infrastructure (OCI) DB System?
- A. Compute Instance
- B. Bucket in Object Storage
- C. Compartment
- D. Virtual Cloud Network
Answer: D
Explanation:
Explanation
The explanation is that a Virtual Cloud Network (VCN) is a software-defined network that you set up in OCI to connect your cloud resources, such as compute instances and databases. A VCN provides you with complete control over your network environment, including selecting your own IP address range, creating subnets, route tables, gateways, security lists, etc. You need to create a VCN before provisioning an OCI DB System, as you need to specify which subnet in your VCN you want to launch your DB System in.
NEW QUESTION # 17
Which statement is true about File System Replication in Oracle Cloud Infrastructure (OCI)?
- A. You can replicate the data in one file system to another file system only in the same region.
- B. You cannot specify a replication interval when you create the replication resource.
- C. Only a file system that has been exported can be used as a target file system.
- D. You can replicate the data in one file system to another file system in the same region or a different region.
Answer: D
Explanation:
Explanation
You can replicate the data in one file system to another file system in the same region or a different region is a true statement about File System Replication in OCI. File System Replication is a feature that allows users to create a copy of a file system in another file system, either within the same region or across regions. This can be useful for disaster recovery, data migration, or data distribution purposes. The other statements are false about File System Replication in OCI. References: [File System Replication]
NEW QUESTION # 18
You are using the Oracle Cloud Infrastructure (OCI) Vault service to create and manage Secrets. For your database password, you have created a secret and rotated the secret one time. The secret versions are as follows:
-----------------------------------------
2 (latest) | Current
1 | Previous
You later realize that you have made a mistake in updating the secret content for version 2 and want to rollback to version 1.
What should you do to rollback to version 1?
- A. From the version 2 (latest) menu, select "Rollback" and select version 1 when given the option.
- B. Create a new secret version 3 and set to Pending. Copy the content of version 1 into version 3.
- C. From the version 1 menu on the OCI console, select "Promote to Current".
- D. Deprecate version 2 (latest). Create new Secret version 3. Create soft link from version 3 to version 1.
Answer: C
Explanation:
From the version 1 menu on the OCI console, select "Promote to Current". The explanation is that when you promote a secret version to current, it becomes the latest version of the secret and is used by default when you access the secret. This way, you can rollback to a previous version of the secret without creating a new version.
NEW QUESTION # 19
You have objects stored in an OCI Object Storage bucket that you want to share with a partner company. You decide to use pre-authenticated requests to grant access to the objects. Which statement is true about preauthenticated requests?
- A. Deleting a pre-authenticated request does not revoke user access to the associated bucket or object.
- B. Pre-authenticated requests can be used to delete buckets or objects.
- C. You need to provide your OCI credentials to the partner company.
- D. You cannot edit a pre-authenticated request.
Answer: D
Explanation:
Explanation
You cannot edit a pre-authenticated request is a true statement about pre-authenticated requests.
Pre-authenticated requests are URLs that allow users to access objects or buckets in OCI Object Storage without requiring additional authentication or authorization. Pre-authenticated requests can be created with an expiration date and time, and can be used for read or write operations. However, once created, pre-authenticated requests cannot be edited, but can only be deleted or extended. The other statements are false about pre-authenticated requests. References: [Pre-Authenticated Requests]
NEW QUESTION # 20
You are responsible for deploying an application on Oracle Cloud Infrastructure (OCI). The application is memory intensive and performs poorly if enough memory is not available. You have created an instance pool of Linux compute instances in OCI to host the application and defined Autoscaling Configuration for the instance pool.
What should you do to ensure that the instance pool autoscales to prevent poor application performance?
- A. Install the monitoring agent on all compute instances, which triggers the autoscaling group.
- B. Configure the autoscaling policy to monitor memory usage and scale up the number of instances when it meets the threshold.
- C. Install OCI SDK on all compute instances and create a script that triggers the autoscaling event if there is high memory usage.
- D. Configure the autoscaling policy to monitor CPU usage and scale up the number of instances when it
Answer: B
Explanation:
meets the threshold
NEW QUESTION # 21
You are using a custom application with third-party APIs to manage the application and data hosted in an OracleCloud Infrastructure (OCI) tenancy. Although your third-party APIs do not support OCI's signature-based authentication, you want them to communicate with OCI resources. Which authentication option should you useto ensure this?
- A. SSH Key Pair with 2048-bit algorithm
- B. OCI Username and Password
- C. Auth Tokens
- D. API Signing Key
Answer: C
Explanation:
Explanation
Auth Tokens is the authentication option that you should use to ensure that your custom application with third-party APIs can communicate with OCI resources. Auth Tokens are tokens that can be used as an alternative to passwords when making API calls to OCI services. Auth Tokens can be generated and revoked by users in the OCI Console or CLI, and can be used with any API client that supports basic authentication.
The other options are not suitable for this scenario, as they either require OCI's signature-based authentication or are not applicable for API calls. References: [Auth Tokens]
NEW QUESTION # 22
You want to distribute DNS traffic to different endpoints based on the location of the end user. Which Traffic Management Steering Policy would you use?
- A. Load Balancer
- B. Failover
- C. IP Prefix
- D. Geolocation
Answer: D
Explanation:
The explanation is that geolocation is a type of Traffic Management Steering Policy that allows you to distribute DNS traffic to different endpoints based on the location of the end user. Geolocation steering policies use geolocation data from third-party providers to map end user IP addresses to geographic regions. You can create rules that specify which endpoints to serve for each region or country, or use a default endpoint for unspecified regions.
NEW QUESTION # 23
You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event. OCI schedules a maintenance due date within 14 to 16 days and sends you a notification.
What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?
- A. You will receive another notification to reboot within the next 14 days.
- B. The instance will get terminated.
- C. You will receive another notification to reboot within the next 7 days.
- D. The instance is either reboot-migrated or rebuilt in place for you.
Answer: D
Explanation:
If you choose not to proactively reboot the instance before the scheduled maintenance due date, the instance is either reboot-migrated or rebuilt in place for you. Reboot-migration is a process where OCI migrates your instance to a new physical host without changing its configuration or public IP address. Rebuild in place is a process where OCI shuts down your instance, performs maintenance on the physical host, and restarts your instance with the same configuration and public IP address. The other options are not correct. Reference: [Reboot-Migration], [Rebuild in Place]
NEW QUESTION # 24
In which two ways can Oracle Security Zones assist with the cloud security shared responsibility model?
- A. Encrypt storage resources with a customer-managed key.
- B. Deny public access to Oracle Cloud Infrastructure resources, such as databases and object storage buckets.
- C. Allow access to an unsecured compartment, which is moved from a standard compartment.
- D. Add or move a standard compartment to a highly secured security zone compartment.
Answer: A,B
Explanation:
Oracle Security Zones is a service that helps you enforce best practices and prevent misconfigurations on your OCI resources by applying predefined policies and controls. Some of the benefits of using Security Zones are:
Encrypt storage resources with a customer-managed key: Security Zones require that all storage resources, such as block volumes, boot volumes, file systems, and object storage buckets, are encrypted with a customer-managed key from Vault. This ensures that you have full control over the encryption and decryption of your data at rest.
Deny public access to OCI resources, such as databases and object storage buckets: Security Zones prevent you from creating or updating OCI resources that have public access enabled, such as databases and object storage buckets that are accessible from the internet. This reduces the risk of unauthorized access or data leakage.
NEW QUESTION # 25
You want to create a policy to allow the NetworkAdmins group to manage Virtual Cloud Network (VCN) in compartment C. You want to attach this policy to the tenancy. The compartment hierarchy is shown below.
Which policy statement can be used to accomplish this task?
- A. Allow group NetworkAdmins to manage virtual-network-family in tenancy
- B. Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C
- C. Allow group NetworkAdmins to manage virtual-network-family in compartment C
- D. Allow group NetworkAdmins to manage virtual-network-family in compartment B:C
Answer: B
Explanation:
Allow group NetworkAdmins to manage virtual-network-family in compartment A:B:C. The explanation is that when you attach a policy to the tenancy, you need to specify the full path of the compartment where you want to grant permissions. In this case, the compartment C is a sub-compartment of compartment B, which is a sub-compartment of compartment A, which is a sub-compartment of the root compartment (tenancy). Therefore, the full path of compartment C is A:B:C. The virtual-network-family resource type includes all the resources related to VCN, such as subnets, route tables, security lists, gateways, etc.
NEW QUESTION # 26
You create a file system and then add a 2 GB file. You then take a snapshot of the file system.
What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete?
- A. 3 GB
- B. 4 GB
- C. 2.5 GB
- D. 2 GB
Answer: D
Explanation:
The total meteredBytes shown by the File Storage service after the hourly update cycle is complete would be 2 GB. This is because snapshots do not consume any additional storage space unless there are changes made to the file system after taking the snapshot. Since no changes were made in this scenario, the snapshot would not add any extra storage cost. Reference: [Snapshots and MeteredBytes]
NEW QUESTION # 27
What should be created before provisioning an Oracle Cloud Infrastructure (OCI) DB System?
- A. Compute Instance
- B. Bucket in Object Storage
- C. Compartment
- D. Virtual Cloud Network
Answer: D
Explanation:
The explanation is that a Virtual Cloud Network (VCN) is a software-defined network that you set up in OCI to connect your cloud resources, such as compute instances and databases. A VCN provides you with complete control over your network environment, including selecting your own IP address range, creating subnets, route tables, gateways, security lists, etc. You need to create a VCN before provisioning an OCI DB System, as you need to specify which subnet in your VCN you want to launch your DB System in.
NEW QUESTION # 28
You need to set up instance principals so that an application running on an instance can call Oracle Cloud Infrastructure (OCI) public services, without the need to configure user credentials.
A developer in your team has already configured the application built using an OCI SDK to authenticate using the instance principals provider.
Which is NOTa necessary step to complete this set up?
- A. Create a policy granting permissions to the dynamic group to access services in your compartment or tenancy.
- B. Generate Auth Tokens to enable instances in the dynamic group to authenticate with APIs.
- C. Create a dynamic group with matching rules to specify which instances can make API calls against services.
- D. Deploy the application and the SDK to all the instances that belong to the dynamic group.
Answer: B
Explanation:
Generating Auth Tokens to enable instances in the dynamic group to authenticate with APIs is not a necessary step to complete this set up. This is because Auth Tokens are used to authenticate users, not instances, when making API calls to OCI services. Instance principals are a feature that allows instances to authenticate themselves using certificates, without requiring user credentials or Auth Tokens. The other options are necessary steps to complete this set up, as they enable instances in the dynamic group to make API calls against services using instance principals and IAM policies. Reference: [Instance Principals], [Auth Tokens]
NEW QUESTION # 29
Which statement is TRUE about delegating an existing domain to the OracleCloud Infrastructure (OCI) DNS service?
- A. Domains can be delegated to OCI DNS from the OCI Marketplace.
- B. Domains can be self-delegated to OCI DNS from its own service portal.
- C. Domains can be delegated to OCI DNS via FastConnect partners.
- D. Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal.
- E. All domains can be retrieved to OCI DNS via DYN.
Answer: D
Explanation:
Explanation
Domains can be delegated to OCI DNS from the Domain Registrar's self-service portal. The explanation is that delegating a domain to OCI DNS means that you are transferring the authority to resolve DNS queries for your domain from your current DNS provider to OCI DNS. To delegate a domain to OCI DNS, you need to create a zone in OCI DNS that matches your domain name and add any records that you want to serve from OCI DNS. Then, you need to update the name servers for your domain at your Domain Registrar's self-service portal with the name servers provided by OCI DNS. This will point your domain to OCI DNS and allow it to resolve DNS queries for your domain.
NEW QUESTION # 30
As a solution architect, you are showcasing the Oracle Cloud Infrastructure (OCI) Object Storage feature about Object Versioning to a customer.
Which statement is true regarding OCI Object Storage Versioning?
- A. A bucket that is versioning-enabled can and will always have the latest version of the object in the bucket.
- B. Object Versioning does not provide data protection against accidental or malicious object update,
- C. Objects are physically deleted from a bucket when versioning is enabled.
- D. Object Versioning is disabled on a bucket by default.
Answer: D
Explanation:
overwrite, or deletion.
Explanation:
Object Versioning is disabled on a bucket by default is a true statement regarding OCI Object Storage Versioning. Object Versioning is a feature that allows users to preserve, retrieve, and restore every version of every object stored in a bucket. Object Versioning is disabled on a bucket by default, but can be enabled or suspended by the user at any time. The other statements are false regarding OCI Object Storage Versioning. Reference: [Object Versioning]

Which TWO statements are NOTcorrect regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. Baseline utilization is a fraction of each CPU core, either 25% or 75%.
- B. Burstable instances are designed for scenarios where an instance is not typically idle and has high CPU utilization.
- C. Burstable instances are charged according to the baseline OCPU.
- D. Burstable instances cost less than regular instances with the same total OCPU count.
- E. If the instance's average CPU utilization over the past 24 hours is below the baseline, the system allows it to burst above the baseline.
Answer: A,B
Explanation:
The explanation is that burstable instances are VM instances that have a baseline utilization of either 12% or 50% of each CPU core, not 25% or 75%. Burstable instances are designed for scenarios where an instance is typically idle or has low CPU utilization but occasionally needs to burst above the baseline to handle spikes in demand. Burstable instances cost less than regular instances with the same total OCPU count but charge extra for bursting above the baseline OCPU.
NEW QUESTION # 33
Which TWO statements about the Oracle Cloud Infrastructure (OCI) File Storage Service are accurate?
- A. Customer can encrypt data in their file system using their own Vault encryption key.
- B. Customer can encrypt the communication to a mount target via export options.
- C. Communication with file systems in a mount target is encrypted via HTTPS.
- D. File systems use Oracle-managed keys by default.
- E. Mount targets use Oracle-managed keys by default.
Answer: A,D
Explanation:
Explanation
File systems use Oracle-managed keys by default. Customer can encrypt data in their file system using their own Vault encryption key. The explanation is that File Storage Service encrypts all data at rest using AES-256 encryption algorithm. By default, File Storage Service uses Oracle-managed keys to encrypt and decrypt data.
However, you can also use your own Vault encryption key to encrypt data in your file system. To do so, you need to create a key in Vault and associate it with your file system when you create or update it.
NEW QUESTION # 34
Your DevOps team needs to interconnect the on-premises network to the Oracle Cloud Infrastructure (OCI) resources, such as a managed database that resides in a private subnet. They indicate that they have a low budget and their bandwidth requirements are minimal, so you decide that a site-to-site VPN is the best option.
They provide you with their router public IP address. You need to create an object in OCI that represents this router. Which object would you create?
- A. Bastion Host
- B. Internet Gateway
- C. Customer Premises Equipment (CPE)
- D. Dynamic Routing Gateway (DRG)
- E. IPSec Tunnel
- F. Virtual Network Interface Card (vNIC)
Answer: C
Explanation:
Customer Premises Equipment (CPE). The explanation is that CPE is an object in OCI that represents your on-premises router or VPN device that connects to your VCN via a site-to-site VPN. A site-to-site VPN is a secure and encrypted connection between your on-premises network and your VCN over the public internet. To set up a site-to-site VPN, you need to create a CPE object with your router's public IP address and other information, such as vendor and platform. You also need to create a Dynamic Routing Gateway (DRG) object in your VCN and attach it to your VCN. Then, you need to create an IPSec connection between your CPE and DRG, which will create two redundant VPN tunnels for high availability.
NEW QUESTION # 35

Which IAM Identity Domain type should you create?
- A. Oracle Apps Premium
- B. External User
- C. Premium
- D. Free
Answer: C
Explanation:
Premium is the IAM Identity Domain type that you should create if you want a full-featured IDaaS solution that helps you manage workforce authentication and access to all of your Oracle and non-Oracle applications. Premium Identity Domain provides users with access to Oracle Identity Cloud Service, which is an IDaaS solution that offers identity management, single sign-on, multifactor authentication, identity governance, and integration with third-party applications. The other options are not IAM Identity Domain types that provide a full-featured IDaaS solution. Reference: [Identity Domains], [Oracle Identity Cloud Service]
NEW QUESTION # 36
Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) approach?
- A. Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges.
- B. Use OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
- C. Private subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
- D. Ensure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
Answer: A
Explanation:
Ensure VCN CIDR prefix overlaps with other VCNs in your tenancy or with your organizations private IP network ranges. The explanation is that a VCN CIDR prefix is the range of IPv4 addresses that can be used within the VCN and its subnets. The VCN CIDR prefix should not overlap with other VCNs in your tenancy or with your organization's private IP network ranges, as this can cause routing conflicts and connectivity issues. You should choose a VCN CIDR prefix that is large enough to accommodate your current and future needs, but not too large to waste IP addresses. You can use any of the private IPv4 address ranges specified in RFC 1918 for your VCN CIDR prefix.
NEW QUESTION # 37
A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance.
Their solutions architects configured the application to use an Oracle Cloud Infrastructure (OCI) Object Storage bucket located in the US West (us-phoenix-1) region to store large amounts of financial dat a. The stored financial data in the bucket should not be impacted even if there is an outage in one of the Availability Domains or a complete region.
What should the architect do to avoid any costly service disruptions and ensure data durability?
- A. Create a replication policy to send data to a different bucket in another OCI region.
- B. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
- C. Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.
- D. Copy the Object Storage bucket to a block volume.
Answer: A
Explanation:
Create a replication policy to send data to a different bucket in another OCI region. The explanation is that replication is a feature of Object Storage that allows you to automatically copy objects from one bucket to another bucket, either in the same region or in a different region. Replication can help you improve data availability and durability, as well as meet compliance and disaster recovery requirements. To enable replication, you need to create a replication policy that specifies the source and destination buckets, the replication frequency, and the replication filters. Replication policies are evaluated every five minutes and copy any new or updated objects from the source bucket to the destination bucket.
