You are designing a networking infrastructure in multiple Oracle Cloud Infrastructure regions and require connectivity between workloads in each region. You have created a dynamic routing gateway (DRG) and a remote peering connection. However, your workloads are unable to communicate with each other.
What are two reasons for this? (Choose two.)

  • A. The security lists associated with subnets in each virtual cloud network (VCN) do not have the appropriate ingress rules
  • B. Identity and Access Management (IAM) policies have not been defined to allow connectivity across the two VCNs in different regions
  • C. A local peering gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the local peering gateway
  • D. An Internet gateway needs to be created in each VCN with a default route rule added in the route table forwarding the traffic to the Internet Gateway
  • E. The route table associated with subnets in each VCN do not have a route rule defined to forward the traffic to their respective DRGs

Answer: AE

Setting Up a Remote Peering
Create the RPCs: Each VCN administrator creates an RPC for their own VCN's DRG. Share information: The administrators share the basic required information.
Set up the required IAM policies for the connection: The administrators set up IAM policies to enable the connection to be established.
Establish the connection: The requestor connects the two RPCs (see Important Remote Peering Concepts the definition of the requestor and acceptor).
Update route tables: Each administrator updates their VCN's route tables to enable traffic between the peered VCNs as desired.
Update security rules: Each administrator updates their VCN's security rules to enable traffic between the peered VCNs as desired.


You are running a mission-critical database application in Oracle Cloud Infrastructure (OCI). You take regular backups of your DB system to OCI object storage. Recently, you notice a failed database backup status in the console.
What step can you take to determine the cause of the backup failure?

  • A. Ensure that your database host can connect to OCI object storage.
  • B. Ensure the database archiving mode is set to NOARCHIVELOG.
  • C. Make sure that the database is not active and running while the backup is in progress.
  • D. Don't restart the dcsagent program even if it has a status of stop/waiting.

Answer: A

Database backups can fail for various reasons. Typically, a backup fails because either the database host cannot access the object store, or there are problems on the host or with the database configuration.
First need to determining the Problem
In the Console, a failed database backup either displays a status of Failed or hangs in the Backup in Progress or Creating state. If the error message does not contain enough information to point you to a solution, you can use the database CLI and log files to gather more data. Then, refer to the applicable section in this topic for a solution.
Database Service Agent Issues
Your Oracle Cloud Infrastructure Database makes use of an agent framework to allow you to manage your database through the cloud platform. Occasionally you might need to restart the dcsagent program if it has the status of stop/waiting to resolve a backup failure.
Object Store Connectivity Issues
Backing up your database to Oracle Cloud Infrastructure Object Storage requires that the host can connect to the applicable Swift endpoint. You can test this connectivity by using a Swift user.
Host Issues
One or more of the following conditions on the database host can cause backups to fail:
- Interactive Commands in the Oracle Profile
- The File System Is Full
- Incorrect Version of the Oracle Database Cloud Backup Module
- Changes to the Site Profile File (glogin.sql)
Database Issues
An improper database state or configuration can lead to failed backups.
- Database Not Running During Backup
- Archiving Mode Set to NOARCHIVELOG (When you provision a new database, the archiving mode is set to ARCHIVELOG by default. This is the required archiving mode for backup operations)
- Stuck Database Archiver Process and Backup Failures
- Temporary Tablespace Errors
- RMAN Configuration and Backup Failures
- RMAN Retention Policy and Backup Failures
- Loss of Objectstore Wallet File and Backup Failures
TDE Wallet and Backup Failures
- Incorrect TDE Wallet Location Specification
- Incorrect State of the TDE Wallet
- Incorrect Configuration Related to the TDE Wallet
- Missing TDE Wallet File
As this is not new provisioned database and already in the ARCHIVELOG , regular backups of DB system to OCI object storage in places, so the best answers are,
- Ensure that your database host can connect to the OCI object storage
- Restart the database service agent

You have hired a new employee to run reports from the Autonomous Data Warehouse (ADW) and are not confident in their SQL writing ability.
Into which consumer group will you assign this individual to minimize the impact of their code?

  • A. Lowest
  • B. Medium
  • C. Highest
  • D. High
  • E. Low

Answer: E

in ADW, The tnsnames.ora file provided with the credentials zip file contains three database service names identifiable as high, medium, and low. The predefined service names provide different levels of performance and concurrency for Autonomous Data Warehouse.
high: The High database service provides the highest level of resources to each SQL statement resulting in the highest performance, but supports the fewest number of concurrent SQL statements. Any SQL statement in this service can use all the CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service is 3, this number is independent of the number of OCPUs in your database.
medium: The Medium database service provides a lower level of resources to each SQL statement potentially resulting a lower level of performance, but supports more concurrent SQL statements. Any SQL statement in this service can use multiple CPU and IO resources in your database. The number of concurrent SQL statements that can be run in this service depends on the number of OCPUs in your database.
low: The Low database service provides the least level of resources to each SQL statement, but supports the most number of concurrent SQL statements. Any SQL statement in this service can use a single CPU and multiple IO resources in your database. The number of concurrent SQL statements that can be run in this service can be up to 300 times the number of OCPUs.
The predefined service names provide different levels of performance and concurrency for Autonomous DB Choose whichever database service offers the best balance of performance and concurrency.
Use the low database service name. to minimize the impact of their SQLs to by low consumer group

boot volume for a minimum of 15 days so you have to increase the boot
You have created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS). You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that both application servers and the DB System can access the file system. The security team determines that the DB System should have read-only access to the file system.
What change would you make to satisfy this requirement?

  • A. Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.
  • B. Connect via SSH to one of the application servers where the file system has been mounte
  • C. Use the Unix command chmod to change permissions on the file system directory, allowing the database user read only access.
  • D. Modify the security list associated with the subnet where the mount target reside
  • E. Change the ingress rules corresponding to the DB System subnet to be stateless.
  • F. Create an instance principal for the DB Syste
  • G. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.

Answer: A

NFS export options enable you to create more granular access control than is possible using just security list rules to limit VCN access. You can use NFS export options to specify access levels
blocks connecting to file systems through exports in a mount target.


You are in the process of setting up a highly available student registration website on Oracle Cloud Infrastructure (OCI). You use a load balancer and a database service on OCI. You launch two compute instances each in a different subnet and add them to the back end set of a public load balancer. The load balancer is configured correctly and working. You then deploy the student registration application on these two compute instances. The application can communicate with the database service. However, when you type the URL of this student registration application in your browser, no web page appears.
What could be the cause?

  • A. The security lists of the subnets on which the two instances are located do not have “allow” rules for port 80 and 443.
  • B. The load balancer performed a health check on the application and found that compute instances were not in a healthy state and terminated the instances.
  • C. The client requested https access to the application and the load balancer service does not support end-to-end SSL from the client to the listener to the back-end set.
  • D. The Dynamic Routing Gateway is preventing the client traffic from your data center network from reaching the public IP of the load balancer.

Answer: A


When creating a subnet, one or more placeholder security lists are often associated with the subnet. Why?

  • A. Each operator needs its own security list.
  • B. Each protocol needs its own security list.
  • C. Each network endpoint or instance in the subnet needs its own security list.
  • D. It is not possible to add or remove security lists after a subnet is created.

Answer: C

Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept (POC) to deploy PeopleSoft.
If your existing resources are being maintained in the root compartment, what is the recommended approach for defining security for the upcoming POC?

  • A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.
  • B. Provision all new resources into the root compartmen
  • C. Grant permissions that only allow for creation and management of resources specific to the POC.
  • D. Provision all new resources into the root compartmen
  • E. Use defined tags to separate resources that belong to different applications.
  • F. Create a new tenancy for the PO
  • G. Provision all new resources into the root compartmen
  • H. Grant appropriate permissions to create and manage resources within the root compartment.

Answer: A

If your organization is small, or if you are still in the proof-of-concept stage of evaluating OracleCloud Infrastructure, consider placing all of your resources in the root compartment (tenancy). This approach makes it easy for you to quickly view and manage all your resources. You can still write policies and create groups to restrict permissions on specific resources to only the users who need access.If you plan to maintain all your resources in the root compartment, we recommend setting up aseparate sandbox compartment to give users a dedicated space to try out features. In the sandbox compartment, you can grant users permissions to create and manage resources, whilemaintaining stricter permissions on the resources in your tenancy (root) compartment.


Which statement is NOT true about the Oracle Cloud Infrastructure Object Storage service?

  • A. Object storage resources can be shared across tenancies.
  • B. Immutable option for data stored in the Object Storage can be set via retention rules.
  • C. Object versioning is enabled at namespace level.
  • D. Object lifecycle rules can be used to either archive or delete objects.

Answer: B
