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.

You have an Oracle Cloud Infrastructure (OCI) load balancer distributing traffic via an evenly-weighted round robin policy to your back-end web servers. You notice that one of your web servers is receiving more traffic than other web servers.
How can you resolve this to make sure traffic is evenly distributed across all back-end webservers?

• A.Disable cookie-based session persistence on your backend set.
• B.Change keep-alive setting between the load balancer and backend server.
• C.Disable SSL configuration associated with your backend set.
• D.Create separate listeners for each backend web server.

You are the Cloud Architect of a company, and are designing a solution on Oracle Cloud Infrastructure where you want to have all your compute instances resistant to hardware failure.
Which two are recommended best practices to achieve the requirement on Oracle Cloud Infrastructure?
(Choose two.)

• A.Create a custom image of your system drive each time you change the image.
• B.Attach block volumes from different Availability Domains to compute instances in different Availability Domains for high availability.
• C.Design your system with redundant compute modes in different Availability Domains to support the failover capability.
• D.Create backups of your block volumes that are associated with compute instances in different regions.
