You are using Oracle Cloud Infrastructure (OCI) services across several regions: us-phoenix-1, us-ashburn-1, uk-london-1 and ap-tokyo-1. You have creates a separate administrator group for each region: PHX-Admins, ASH-Admins, LHR-Admins and NRT-Admins, respectively. You want to restrict admin access to a specific region. E.g., PHX-Admins should be able to manage all resources in the us phoenix-1 region only and not any other OCI regions. What IAM policy syntax is required to restrict PHX-Admins to manage OCI resources in the us-phoenix-1 region only? (Choose the best answer.)

• A. Allow group PHX-Admins to manage all-resources in tenancy where re-guest.region='us-phoenix-1'
• B. Allow group PHX-Admins to manage all-resources intenancy where re-guest.location='us-phoenix-1'
• C. Allow group PHX-Admins to manage all-resources in tenancy where re-guest.permission=
  'us-phoenix-1'
• D. Allow group PHX-Admins to manage all-resources in tenancy where re-guest.target='us-phoenix-1'

In your root compartment, you have two subcompartments, A and B. You have three in-stances in each compartment, including the root (for a total of nine). What does the following metric query return if you use the console to run it in the root compartment? CpuUtiliza-tion[1m].mean()

• A. One time series: the average CPU utilization over all nine instances per minute
• B. Three different time series: each time series represents the average CPU utilization of one of the three instances in the root compartment per minute.
• C. One time series: the average CPU utilization over the three instances in the root compartment per minute
• D. One number: the average CPU utilization over all nine instances over the last minute

• B. Paravirtualization utilizes the internal storage stack of compute instance OS and net-work hardware virtualization to access block volumes.
• C. Paravirtualized is required to manage iSCSI configuration for virtual machine instances.
• D. Paravirtualized volumes become immediately available on bare metal compute instances.

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. 60 days after the initial creation, any object will be deleted. Deletion will physically de-lete all versions of the object.
• C. Once any specific version is 60 days old, it will be deleted. Deletion will physically delete the data.
• 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.
