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.

Which two statements are true about subnets within a VCN? (Choose two.)

A. You can have multiple subnets in an Availability Domain for a given VCN.

B. Private and Public subnets cannot reside in the same Availability Domain for a given VCN.

C. Subnets can have their IP addresses overlap with other subnets in another network for a given VCN.

D. Instances obtain their private IP and the associated security list from their subnets.

You have a shared file system between two web servers using File Storage Service (FSS) and you were tasked to create a backup plan for this environment to protect the data placed into the shared file system.

What is the recommended approach to create this backup using FSS features?

A. Implement a backup policy to execute a snapshot of the shared volume.

B. Implement a backup policy to copy data from the shared volume to object storage.

C. Compress the data that is in the shared volume and copy it into a different folder on the boot volume disk.

D. Use the rsync tool to send data from the shared volume to a boot volume disk.

E. Use the rsync tool to send data from the shared volume to a block volume.

You are designing a high bandwidth, redundant connection between your data center and Oracle Cloud

Infrastructure (OCI). While researching for OCI FastConnect locations, you notice that you are co-located

with Oracle at one of the Oracle FastConnect locations in the Ashburn region.

What is the recommended design in this scenario?

A. Create a cross-connect group and have two or more cross-connects in that group. Create an IPsec VPN connection on this group.

B. Setup two IPsec connections between your data center and OCI Ashburn region. Create a OCI load balancer to distribute the traffic across the two connections.

C. Create a cross-connect group and have at least two or more cross-connects in that group. Create at least two or more virtual circuits in the group.

D. Create a cross-connect group and have at least one cross-connect in that group. Create at least one virtual circuit in the group.

As the Cloud Architect for your company, you have been tasked with designing a high performance (HPC)

cluster in Oracle Cloud Infrastructure (OCI). The following requirements have been defined:

The cluster must be a minimum of three nodes, but may increase to six nodes when demand requires.

The cluster must be resilient to any potential infrastructure failures.

To minimize latency, all nodes must be deployed within the same availability domain (AD).

Adding or replacing nodes within the cluster should take no more than 30 minutes.

Which two steps should be performed to satisfy these requirements in OCI? (Choose two.)

A. Deploy the cluster in a single AD with a shared file system that leverages the file storage service (FSS). Deploy a standby cluster in another AD and configure it to use the same shared file system.

B. Deploy the cluster in a single AD. Place each of the nodes in one of the three different fault domains in that AD.

C. Create a backup of your HPC node compute instance boot volume. Launch new compute instances directly from the backup reduce provisioning time.

D. Create a custom image of your HPC node compute instance. Launch new compute instances using this image to reduce provisioning time.

E. Deploy the cluster in a single AD. Place each of the nodes in a different virtual cloud network (VCN) subnet.
