• Question 171:

  Which three can you achieve by using Terraform? (Choose three.)

  A. Create resources in the right order without regard to the order in the terraform plan file.

  B. Automatically re-provision the resources that are tainted or whose configuration has changed.

  C. Automatically translate a deployed infrastructure and create a plan.

  D. Automatically destroy all the resources that are in tenancy.

  E. Continuously maintain the configuration files in an instance.

  Correct Answer: ABD

• Question 172:

  Your application front end consists of several Oracle Cloud Infrastructure compute instances behind a public load balancer. You have configured the load balancer to perform health checks on these instances. What will happen if an instance fails to pass the configured health checks?

  A. The instance is replaced automatically by the load balancer.

  B. The instance is terminated automatically by the load balancer.

  C. The instance is taken out of the back end set by the load balancer.

  D. The load balancer stops sending traffic to that instance.

  Correct Answer: D

  One or more of the backend servers reports as unhealthy. A backend server might be unhealthy or the health check might be misconfigured.

• Question 173:

  B. Availability Domain

  C. Virtual Cloud Network

  D. host name

  E. instance shape

  F. image operating system

  G. private IP address

  Correct Answer: ABCEF

• Question 175:

  Which two statements are true about Oracle Cloud Infrastructure Compute Service? (Choose two.)

  A. You can launch a virtual or bare metal instance by using the same LaunchInstance API.

  B. You cannot launch a bare metal server in Oracle Cloud Infrastructure Compute Service.

  C. You can attach a block volume in an Availability Domain other than your compute instance.

  D. You can share custom images across tenancies and regions.

  Correct Answer: AD

  References: Regions and Availability Domains Volumes are only accessible to instances in the same availability domain . You cannot move a volume between availability domains or regions. FYI: https://docs.cloud.oracle.com/iaas/Content/Block/Concepts/overview.htm

• Question 176:

  You want an instance in your compartment to make API calls to other services within Oracle Cloud

  Infrastructure without storing credentials in a configuration file.

  What do you need to do?

  A. No action is required. By default, all VM instances are created with an Instance Principal.

  B. Instances cannot access services outside their compartment.

  C. VM instances are treated as users. Create a user and assign the user to that VM instance.

  D. Create appropriate matching rules in the Dynamic Group to create an Instance Principal.

  Correct Answer: D

• Question 177:

  Which three must be configured for a load balancer to accept incoming traffic? (Choose two.)

  A. a listener

  B. a back-end server

  C. a back end set

  D. a security list that is open on a listener port

  E. a certificate

  Correct Answer: ABC

  https://docs.cloud.oracle.com/iaas/Content/Balance/Tasks/managingloadbalancer.htm?tocpath=Ser vices %7CLoad%20Balancing%7C_____5 The essential components for load balancing include: ?A load balancer with pre-provisioned bandwidth. ?A backend set with a health check policy. See Managing Backend Sets. ?Backend servers for your backend set. See Managing Backend Servers. ?One or more listeners . See Managing Load Balancer Listeners. ?Load balancer subnet security rules to allow the intended traffic. To learn more about these rules, see Security Rules. ?Optionally, you can associate your listeners with SSL server certificate bundles to manage how your system handles SSL traffic. See Managing SSL Certificates

• Question 178:

  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

  Correct Answer: D

• Question 179:

  Which two are true for achieving High Availability on Oracle Cloud Infrastructure? (Choose two.)

  A. Store your database across multiple regions so that half of the data resides in one region and the other half resides in another region.

  B. Attach your block volume form Availability Domain 1 to a compute instance in Availability Domain 2 (and vice versa) so that they are highly available.

  C. Configure your database to have Data Guard in another Availability Domain in Sync mode within a region.

  D. Store your database files on Object Storage so that they are available in all Availability Domains in all regions.

  E. Distribute your application servers across all Availability Domains within a region.

  Correct Answer: CE

• Question 180:

  Which two configuration formats does Terraform support? (Choose two.)

  A. YAML

  B. JSON

  C. HCL

  D. XML

  Correct Answer: BC
