Which statement is true about interconnecting Virtual CloudNetwork (VCN)?

• A.VCNs must be in the same tenancy to be peered.
• B.VCNs support transitive peering.
• C.The only way to interconnect VCNs is through peering.
• D.Peering VCNs should not have overlapping CIDR blocks.

Which three actions need to be performed before attempting a data transfer service job?

• A.Create an object bucket to receivethe job.
• B.Set up SSH access to a host on OCI to coordinate the transfer job.
• C.Obtain an available host machine which can run the dts utility on-premise with SATA or USB drives attached for the transferjob.
• D.Get access to a high-speed internet connection
• E.Data Transfer Service and Storage Service Limits should be checked and raised if required.

You have launched a compute instance runningOracle database in a private subnet in the Oracle Cloud Infrastructure US East region. You have also created a Service Gateway to back up the data files to OCI Object Storage in the same region. You have modified the security list associated with the private subnet to allow traffic to the Service Gateway, but your instance still cannot access OCI Object Storage. How can you resolve this issue?

• A.Add a stateful rule that enables egress HTTPS (TCP port 443) traffic to OCI Object Storage in the security list associated with the private subnet
• B.Add a stateful rule that enables ingress HTTPS (TOP port 443) traffic to 001 Object Storage in the securitylist associated with the private subnet
• C.Use the default Security List, which has ports open for OCI Object Storage
• D.Add a rule in the Route Table associated with the private subnet with Target type as "Service Gateway" and destination service as all IAD services in the Oracle Service Network.'

Which statement is true about restoring a block volume from a manual or policy-based block volumebackup?

• A.It must be restored as new volumes to the same Availability Domain on which the original block volume backup resides.
• B.It can be restored as new volumesto any Availability Domain across different regions.
• C.It can be restored as new volumes with different sizes from the backups.
• D.It can be restored as new volumes to any Availability Domain within the same region.

You have an application running on Oracle Cloud Infrastructure. You identified that the read and write operations are slowing your applicationdown enough to impair user access. The application is currently using a VM.Standard 1.2 compute without any block storage attached to it.
Which two options allow you to increase disk performance? (Choose two.)

• A.Terminate the compute instance and create a backup of the boot volume. Create a new compute instance using aVM Dense IO shape and restore the backup.
• B.Terminate the compute instance preservingthe boot volume. Create a new compute instance using a VM Dense IO shape using the boot volume preserved.
• C.Terminate the compute instance preserving the boot volume. Create a new compute instance using a VM Standard shape and attach a new block volume to host your application.
• D.Create a backup of the boot volume. Create a new compute instance using a VM Dense IO shape and restore the backup.
