  E. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved and attach a new block volume to host your application.
  D. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.HPC2.36 shape using the boot volume preserved and use the NVMe devices to host your application.
  E. Terminate the compute instance preserving the boot volume. Create a new compute instance using the BM.GPU2.2 shape using the boot volume preserved and attach a new block volume to host your application.

• Question 72:

  You have successfully configured identity federation between Oracle Cloud Infrastructure (OCI) and Oracle Identity Cloud Services (IDCS). A new project manager wants access to OCI for her team and provides the name of an existing group within IDCS to use when granting access. How do you configure federation to allow the project team access to OCI resources?

  A. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new policy in IDCS and reference the name of the IAM group.
  B. Create a new Identity and Access Management (IAM) policy in OCI and reference the name of the IDCS group in each policy statement.
  C. Create a new compartment in OCI with the same name as the existing IDCS group. Create an IAM policy that references the new compartment and the name of the IDCS group.
  D. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new IAM policy and reference the name of the IAM group in each policy statement.
  D. Create a new IAM group in OCI and map it to the existing IDCS group. Create a new IAM policy and reference the name of the IAM group in each policy statement.

  When working with your IdP, your administrator defines groups and assigns each user to one or more groups according to the type of access the user needs. Oracle Cloud Infrastructure also uses the concept of groups (in conjunction with IAM policies) to define the type of access a user has. As part of setting up the relationship with the IdP, your administrator can map each IdP group to a similarly defined IAM group, so that your company can re-use the IdP group definitions when authorizing user access to Oracle Cloud Infrastructure resources. Here's a screenshot from the mapping process:

  

• Question 73:

  What happens after you successfully run the following command on your Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) using the YAML file defined below? kubectl create -f definition.yml YAML file ?definition.yml

  

  A. A single Pod with a single container is created.
  B. Two Pods with a container each are created.
  C. A single Pod with two containers is created.
  D. No Pod gets created.
  C. A single Pod with two containers is created.

• Question 74:

  What is the maximum IP address size range that you can have in a Virtual Cloud Network?

  A. /16
  B. /26
  C. /24
  D. /8
  A. /16

  ---

  When you create your VCN, you assign a contiguous IPv4 CIDR block of your choice. VCN sizes ranging from /16 (65,533 IP addresses) to /30 (1 IP address) are allowed. Example: 10.0.0.0/16, 192.168.0.0/24.

• Question 75:

  Which option is NOT a valid action within the Oracle Cloud Infrastructure (OCI) Block Volume service?

  A. Clone an existing volume to a new, larger volume.
  B. Restore from a volume backup to a larger volume.
  C. Shrink an existing volume in place with offline resizing.
  D. Expand an existing volume in place with offline resizing.
  C. Shrink an existing volume in place with offline resizing.

• Question 76:

  Which deployment architecture is offered when you deploy the Platform Service Manager based Database Cloud Service (DBCS) onto Oracle Cloud Infrastructure?

  A. Two node Primary RAC database leveraging ACFS for the shared file system
  B. Single Instance database with a Single Instance Data Guard in Maximum Performance mode
  C. Single Instance database with a Single Instance Data Guard in Maximum Protection mode
  D. Two node Primary RAC database with a two node RAC Data Guard Standby in Maximum Performance mode
  D. Two node Primary RAC database with a two node RAC Data Guard Standby in Maximum Performance mode

• Question 77:

  What is the maximum number of security lists that can be associated with a subnet?

  A. four
  B. three
  C. five
  D. two
  C. five

  ---

  you may optionally specify one or more security lists for the subnet to use (up to five). If you don't specify any, the subnet uses the cloud network's default security list. You can change which security list the subnet uses at any time. https://docs.cloud.oracle.com/iaas/Content/Network/Tasks/managingVCNs.htm

• Question 78:

  What does Terraform use to create, manage, and manipulate infrastructure resources?

  A. resources
  B. provisioner
  C. instances
  D. provider
  D. provider

  ---

  The Oracle Cloud Infrastructure provider is used to interact with the many resources supported by the Oracle Cloud Infrastructure. The provider needs to be configured with credentials for the Oracle Cloud Infrastructure account.

• Question 79:

  You are managing a tier-1 OLTP application on an Autonomous Transaction Processing (ATP) database. Your business needs to run hourly batch processes on this ATP database that may consume more CPUs than what is available on the

  server.

  How can you limit these batch processes to not interfere with the OLTP transactions?

  A. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.
  B. Copy OLTP data into new tables in a new table space and run batch processes against these new tables.
  C. Disable automated backup during the batch process operations.
  D. ATP is designed for OLTP workload only, you cannot run batch processes on ATP.
  A. Configure ATP resource management rules to change CPU/IO shares for the consumer group of batch processes.

  ---

  Autonomous Transaction Processing comes with predefined CPU/IO shares assigned to different consumer groups. You can modify these predefined CPU/IO shares if your workload requires different CPU/IO resource allocations.

  By default, the CPU/IO shares assigned to the consumer groups TPURGENT, TP, HIGH, MEDIUM, and LOW are 12, 8, 4, 2, and 1, respectively. The shares determine how much CPU/IO resources a consumer group can use with respect to

  the other consumer groups. With the default settings the consumer group TPURGENT will be able to use 12 times more CPU/IO resources compared to LOW, when needed. The consumer group TP will be able to use 4 times more CPU/IO

  resources compared to MEDIUM, when needed.
