You have a Linux compute instance located in a public subnet in a VCN which hosts a web application. The security list attached to subnet containing the compute instance has the following stateful ingress rule.

The Route table attached to the Public subnet is shown below.You can establish an SSH connection into the compute instance from the internet. However, you are not able to connect to the web server using your web browser.

Which step will resolve the issue? (Choose the best answer.)

• A. In the security list, add an ingress rule for port 80 (http).
• B. In the security list, remove the ssh rule.
• C. In the route table, add a rule for your default traffic to be routed to NAT gateway.
• D. In the route table, add a rule for your default traffic to be routed to service gateway.

Your company hosts a web application on OCI usingcompute instances and block volumes. To minimize your recovery point objective (RPO), you enable cross-region block volume replication for the block volumes.
Which option is true regarding cross-region volume replication?

• A. The replica cannot be directly mounted on a compute instance. Instead, it must be activated, creating a clone that will be available for mounting.
• B. Replication is synchronous, so it may slightly degrade block volume performance.
• C. Replication replaces the need for block volume backups.
• D. The cost of the replica matches the cost of the source volume; for example, the replica of a high-performance volume will be billed at the high-performance rate.

One of your development teams has asked for your help tostandardize the creation of several compute instances that must be provisioned each day of the week. You initially write several Command Line Interface (CLI) commands with all appropriate configuration parameters to achieve this task later determining this method lacks flexibility. Which command generates a JSON-based template that Oracle Cloud Infrastructure (OCI) CLI can use to provision these instances on a regular basis? (Choose the best answer.)

• A. oci compute provision-instance --generate-full-command-json-input
• B. oci compute instance launch --generate-cli-skeleton
• C. oci compute instance create --generate-cli-skeleton
• D. oci compute instance launch --generate-full-command-json-input

You have been contracted by a local e-commerce company to assist with enhancing their online shopping application. The application is currently deployed in a single Oracle Cloud Infrastructure (OCI) region. The application utilizes a public load balancer, application servers in a private subnet, and a database in a separate, private subnet. The company would like to deploy another set of similar infrastructure in a different OCI region that will act as standby site. In the event of a failure at the primary site, all customers should be routed to the failover site automatically. After deploying the additional infrastructure within the second region, how should you configure automated failover requirements? (Choose the best answer.)

• A. Create a load balancer policy in the Traffic Management service. Configure one answer for each site.
  Set the answer for the primary sitewith a weight of 10 and the answer for the secondary site with a weight of 100.
• B. Create a new A record in DNS that points to the public load balancer at the secondary site. Create a CNAME for the sub-domain failover that will resolve to the new A rec-ord. Inform customers to prepend the website URL with failover if the primary site is unavailable.
• C. Create a failover policy in the Traffic Management service. Set the IP address of the public load balancer for the primary site in answer pool 1. Set the IP address of the public load balancer for the secondary site in answer pool 2. Define a health check to monitor both sites.
• D. Deploy a new load balancer in the primary region. Create one backend set for the primary application servers and a second backend set for the standby application servers. Create a listener for the primary backend set with a timeout of 3 minutes. Create a listener for the secondary backend set with a timeout of 10 minutes.

You use a bucket in Object Storage to store backups of a database. Versioning is enabled on these objects, so that every time you take a new backup, it creates a new version. You add the following life-cycle policy rule: {
"action": "DELETE","is-enabled": true, "name": "Delete-Rule", "object-name-filter": null, "target": "objects",
"time-amount": 60, "time-unit": "DAYS" } Which option is true regarding this rule?

• A. If 60 days passes for an object without a new version being created, it will be deleted. Deletion marks the latest version as deleted but does not physically delete it.
• B. Once any specific version is 60 days old, it will be deleted. Deletion will physically delete the data.
• C. 60 days after the initial creation, any object will be deleted. Deletion will physically de-lete all versions of the object.
• D. 60 days after the initial creation, any object will be deleted. Deletion marks the latest version as deleted but does not physically delete it.
