Your company decided to move a few applications to Oracle Cloud Infrastructure (OCI) in the US West (us-phoenix-1) region.
You need to design a cloud-based disaster recovery (DR) solution with a requirement to deploy the DR resources in the US East (us-ashburn-1) region to minimize network latency.
What is the recommended deployment?

  • A. Deploy production and DR applications in two separate virtual cloud networks (VCNs), each in different regions, and then use VCN local peering gateways for connectivity.
  • B. Deploy production and DR applications in two separate VCNs, each in different region
  • C. Connect them using a VCN remote peering connection.
  • D. Deploy production and DR applications in the same VC
  • E. Create production subnets in one AD, and DR subnets in another AD (assume a multi-AD region).
  • F. Deploy production and DR applications in two separate VCNs in different availability domains (ADs) within the primary region, and then use a VCN remote peering connection for connectivity.

Answer: A

Remote VCN peering is the process of connecting two VCNs in different regions
The peering allows the VCNs' resources to communicate using private IP addresses without routing the traffic over the internet or through your on-premises network.

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

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.

You created a public subnet and an internet gateway in your virtual cloud network (VCN) of Oracle Cloud Infrastructure. The public subnet has an associated route table and security list. However, after creating several compute instances in the public subnet, none can reach the Internet.
Which two are possible reasons for the connectivity issue? (Choose two.)

  • A. The route table has no default route for routing traffic to the internet gateway.
  • B. There is no stateful egress rule in the security list associated with the public subnet.
  • C. There is no dynamic routing gateway (DRG) associated with the VCN.
  • D. There is no stateful ingress rule in the security list associated with the public subnet.
  • E. A NAT gateway is needed to enable the communication flow to internet.

Answer: AB

An internet gateway as an optional virtual router that connects the edge of the VCN with the internet. To use the gateway, the hosts on both ends of the connection must have public IP addresses for routing. Connections that originate in your VCN and are destined for a public IP address (either inside or outside the VCN) go through the internet gateway. Connections that originate outside the VCN and are destined for a public IP address inside the VCN go through the internet gateway.
Working with Internet Gateways
You create an internet gateway in the context of a specific VCN. In other words, the internet gateway is automatically attached to a VCN. However, you can disable and re-enable the internet gateway at any time.
Compare this with a dynamic routing gateway (DRG), which you create as a standalone object that you
then attach to a particular VCN. DRGs use a different model because they're intended to be modular building blocks for privately connecting VCNs to your on-premises network.
For traffic to flow between a subnet and an internet gateway, you must create a route rule accordingly in the subnet's route table (for example, destination CIDR = and target = internet gateway). If the internet gateway is disabled, that means no traffic will flow to or from the internet even if there's a route rule that enables that traffic. For more information, see Route Tables.
For the purposes of access control, you must specify the compartment where you want the internet gateway to reside. If you're not sure which compartment to use, put the internet gateway in the same compartment as the cloud network. For more information, see Access Control.
You may optionally assign a friendly name to the internet gateway. It doesn't have to be unique, and you can change it later. Oracle automatically assigns the internet gateway a unique identifier called an Oracle Cloud ID (OCID). For more information, see Resource Identifiers.
To delete an internet gateway, it does not have to be disabled, but there must not be a route table that lists it as a target.
AS per compute instances can connect to the Internet so you use egress no ingress

Your company is moving an Internet-facing, 2-tier web application into Oracle Cloud Infrastructure. The application must have a highly available architecture.
Which two design options would you consider? (Choose two.)

  • A. Configure a Dynamic Route Gateway in your VCN and make it highly available.
  • B. Configure a NAT instance in your Virtual Cloud Network (VCN). Create a route rule by using the private IP of the NAT instance as a route target for all the private subnets in your VCN.
  • C. Create an Internet Gateway and attach it to your VC
  • D. Deploy public load balancer nodes into two Available Domains.
  • E. Place all web servers behind a public load balancer.

Answer: CD


You are a network architect and have designed the network infrastructure of a three-tier application on Oracle Cloud Infrastructure (OCI). In the architecture, back-end DB servers are in a private subnet. One of your DB administrators requests to have access to OCI object storage service.
How can you meet this requirement?

  • A. Add a new route rule to the private subnet route table to route default traffic to the internet gateway.
  • B. Attach a public IP address to the instances in the private subnet, and then add a new route rule to the private subnet route table to route default traffic to the internet gateway.
  • C. Create a dynamic routing gateway (DRG) and attach it to your virtual cloud network (VCN). Add a default route rule to the private subnets route table and set the target as DRG.
  • D. Create a service gateway, add a new route rule to the private subnet route table that uses object storage as target type.

Answer: D

A service gateway lets resources in your VCN privately access specific Oracle services, without exposing the data to an internet gateway or NAT. The resources in the VCN can be in a private subnet and use only private IP addresses. The traffic from the VCN to the service of interest travels over the Oracle network fabric and never traverses the internet.
To give your VCN access to a given service CIDR label, you must enable that service CIDR label for the VCN's service gateway. You can do that when you create the service gateway, or later after it's created. You can also disable a service CIDR label for the service gateway at any time.
For traffic to be routed from a subnet in your VCN to a service gateway, you must add a rule accordingly to the subnet's route table. The rule must use the service gateway as the target.


Which two resources reside exclusively in a single Oracle Cloud Infrastructure Availability Domain? (Choose two.)
