• Question 152:

  You are deploying a highly available web application in Oracle Cloud Infrastructure and have decided to use a public load balancer. The back-end web servers will be distributed across all three availability domains (ADs). How many subnets should you create to deliver a secure highly available application?

  A. three subnets in total; one subnet in each AD
  B. five subnets in total; two subnets each in the first and second AD with a single subnet in the third AD
  C. six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers
  D. four subnets in total; one subnet in each AD for the web servers and a single subnet in any one AD for the load balancer
  C. six subnets in total; two subnets in each AD; one for the load balancer and one for the web servers

• Question 153:

  When terminating a compute instance, which statement is true?

  A. The instance needs to be stopped first, and then terminated.
  B. The boot volume is always deleted.
  C. All block volumes attached to the instance are terminated.
  D. Users can preserve the boot volume associated with the instance.
  D. Users can preserve the boot volume associated with the instance.

  ---

  You can permanently terminate (delete) instances that you no longer need. Any attached VNICs and volumes are automatically detached when the instance terminates. Eventually, the instance's public and private IP addresses are released and become available for other instances. By default, the instance's boot volume is deleted when you terminate the instance, however you can preserve the boot volume associated with the instance, so that you can attach it to a different instance as a data volume, or use it to launch a new instance.

• Question 154:

  You have provisioned an Autonomous Data Warehouse (ADW) database with 16 enabled OCPUs and need to configure the consumer group for your application. Which two are true when deciding the number of sessions for each application? (Choose two.)

  A. The MEDIUM and LOW consumer group can run up to 16 concurrent SQL statements if HIGH consumer group has 0 SQL statements
  B. The HIGH consumer group can run up to 16 concurrent SQL statements as long as MEDIUM and LOW consumer groups have 0 SQL statements
  C. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has 0 SQL statements
  D. The HIGH consumer group can run up to 16 concurrent SQL statements in addition to 32 concurrent SQL statements in MEDIUM and LOW consumer group each
  E. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has 0 SQL statements
  C. The MEDIUM consumer group can run 20 concurrent SQL statements when HIGH consumer group has 0 SQL statements
  E. The HIGH consumer group can run 3 concurrent SQL statements when MEDIUM consumer group has 0 SQL statements

• Question 155:

  Which two statements about file storage service (FSS) are accurate? (Choose two.)

  A. FSS leverages UNIX user group and permission checking for file access security
  B. Encryption of file system in FSS is optional
  C. Identity and Access Management (IAM) controls which file systems are mountable by which instances
  D. Security lists can be used as a virtual firewall to prevent an instance from mounting an FSS mount target within the same subnet
  E. Data in transit to an FSS mount target is encrypted
  A. FSS leverages UNIX user group and permission checking for file access security
  E. Data in transit to an FSS mount target is encrypted

  ---

  All data is encrypted at rest. and In-transit encryption provides a way to secure your data between instances and mounted file systems using TLS v. 1.2 (Transport Layer Security) encryption. File Storage service supports the AUTH_UNIX style of authentication and permission checking for remote NFS client requests.

• Question 156:

  Which two statements about Oracle Cloud Infrastructure File Storage Service are accurate? (Choose two.)

  A. Customer can encrypt the communication to a mount target via export options.
  B. Mount targets use Oracle-managed keys by default.
  C. File systems use Oracle-managed keys by default.
  D. Customer can encrypt data in their file system using their own Vault encryption key.
  E. Communication with file systems in a mount target is encrypted via HTTPS.
  B. Mount targets use Oracle-managed keys by default.
  D. Customer can encrypt data in their file system using their own Vault encryption key.

• Question 157:

  Your company has been running several small applications in Oracle Cloud Infrastructure and is planning a proof-of-concept (POC) to deploy PeopleSoft. If your existing resources are being maintained in the root compartment, what is the recommended approach for defining security for the upcoming POC?

  A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.
  B. Provision all new resources into the root compartment. Grant permissions that only allow for creation and management of resources specific to the POC.
  C. Provision all new resources into the root compartment. Use defined tags to separate resources that belong to different applications.
  D. Create a new tenancy for the POC. Provision all new resources into the root compartment. Grant appropriate permissions to create and manage resources within the root compartment.
  A. Create a new compartment for the POC and grant appropriate permissions to create and manage resources within the compartment.

  ---

  If your organization is small, or if you are still in the proof-of-concept stage of evaluating Oracle Cloud Infrastructure, consider placing all of your resources in the root compartment (tenancy). This approach makes it easy for you to quickly view and manage all your resources. You can still write policies and create groups to restrict permissions on specific resources to only the users who need access. If you plan to maintain all your resources in the root compartment, we recommend setting up a separate sandbox compartment to give users a dedicated space to try out features. In the sandbox compartment, you can grant users permissions to create and manage resources, while maintaining stricter permissions on the resources in your tenancy (root) compartment. https://www.oracle.com/a/ocom/docs/best-practices-for-iam-on-oci.pdf

• Question 158:

  Which statement is true about a pre-authenticated request in Oracle Cloud Infrastructure Object Storage?

  A. You can create only 1, 000 pre-authenticated requests per bucket.
  B. You can create a pre-authenticated request only for public buckets.
  C. You cannot retire a pre-authenticated request before it expires.
  D. You cannot extend the expiration date on a pre-authenticated request.
  D. You cannot extend the expiration date on a pre-authenticated request.

  ---

  https://docs.cloud.oracle.com/iaas/Content/Object/Tasks/usingpreauthenticatedrequests.htm You can create an unlimited number of pre-authenticated requests. You can't edit a pre-authenticated request. If you want to change user access options in response to changing requirements, you must create a new pre-authenticated request. URL: https://docs.cloud.oracle.com/iaas/Content/Object/Tasks/managingbuckets.htm You can change a bucket's access from public to private or from private to public. Changing the type of access doesn't affect existing pre-authenticated requests. Existing pre-authenticated requests still work.

• Question 159:

  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:
