Oracle Cloud Infrastructure 2021 Cloud Operations Associate: 1Z0-1067-21

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 site with 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 record. 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.

Recently, your e-commerce web application has been receiving significantly more traffic than usual. Users are reporting they often encounter a 503 Service Error when trying to access your site. Sometimes the site is very slow.

You check your instance pool configuration to confirm that the maximum number of instances is configured to allow 20 compute instances. Currently, 14 compute instances have been provisioned by the instance pool. You also confirm that current CPU utilization across all hosts exceeds the scale-out threshold you set in your auto-scaling policy. However, the instance pool is not provisioning any new instances.

What can you check to determine why the application is NOT functioning properly? (Choose the best answer.)

A. Verify that the new offer feature code did not introduce any performance bugs.

B. Verify that the database is accessible.

C. Verify that the compute resource quota has not been exceeded.

D. Verify that the Quality Assurance team is not currently performing load-testing against production.

You are working as a Cloud Operations Administrator for your company. They have different Oracle Cloud Infrastructure (OCI) tenancies for development and production workloads. Each tenancy has resources in two regions – uk-london-1 and eu-frankfurt-1. You are asked to manage all resources and to automate all the tasks using OCI Command Line Interface (CLI).

Which is the most efficient method to manage multiple environments using OCI CLI? (Choose the best answer.)

A. Use OCI CLI profiles to create multiple sets of credentials in your config file, and reference the appropriate profile at runtime.

B. Create environment variables for the sets of credentials that align to each combination of tenancy, region, and environment.

C. Run oci setup config to create new credentials for each environment every time you want to access the environment.

D. Use different bash terminals for each environment.
