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.

At the end of a terraform apply operation, what is the default output?

A. nothing by default

B. statistics about what was added, changed, and destroyed

C. the entire state file

D. statistics about what was added, changed, and destroyed, and the values of outputs

In which language are Terraform and Terraform providers written?

A. Python

B. Go

C. C

D. Ruby

For a compute instance that is launched in a private subnet in a Virtual Cloud Network (VCN), which action needs to be performed to connect to the Internet, assuming that the required security list is properly set up?

A. Assign a Public IP address to the compute instance.

B. Create and configure Network Address Translation (NAT) in a public subnet and route all traffic to it.

C. There is no way for an instance in a private subnet to connect to the Internet.

D. Create a default route entry in the route table to forward all traffic to the Internet gateway.

Your company has decided to move a few applications to Oracle Cloud and you have been asked to design it for both High Availability (HA) and Disaster Recovery (DR). Which two should you consider while designing your Oracle Cloud Infrastructure architecture? (Choose two.)

A. Region

B. Instance Shape

C. Compartments

D. Availability Domain

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.

How can you provide users access to an existing compartment?

A. by granting users access to a compartment when the compartment is created

B. by adding users to a group and defining a policy to provide the group access to the compartment

C. by adding users to a compartment. All users in the compartment will have access to the objects in the compartment.

D. by granting access directly to the user when the user is created

Your company has decided to move a few applications to Oracle Cloud Infrastructure and you have been asked to design it for Disaster Recovery (DR). One of the items of your design is to deploy the DR at least 300 miles from the home site and minimize the network latency as much as possible. Based on that, what will be the recommended deployment?

A. Deploy applications in two separated VCNs in different Availability Domains and use VCN Remote Peering

B. Deploy applications in different regions and have them connected using VCN Remote Peering

C. Deploy applications in two separated VCNs in different regions and use VCN Local Peering

D. Deploy applications on the same region splitting workloads across Availability Domains.

Which two Oracle Cloud Infrastructure services use a Dynamic Routing Gateway?

A. OCI FastConnect Public Peering

B. Local Peering

C. OCI FastConnect Private Peering

D. Internet Gateway

E. OCI IPSec VPN Connect

Which three load-balancing policies can be used with a backend set?

A. throughput

B. least connections

C. IP hash

D. CPU utilization

E. weighted round robin
