Your organization has deployed a large, complex application across multiple compute instances in Oracle Cloud Infrastructure (OCI). These compute instances also have block volume storage attached to them. You want to create a time consistent backup of these block volume storage.

Which implementation strategy should be used?

  1. Create a manual backup of each volume
  2. Use scripts available in OCI to backup block volume storage
  3. Group volumes in a volume group first and then use available scripts in OCI
  4. Group volumes in a volume group and create a manual backup of the volume group

Answer(s): D

Explanation:

The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group. A volume group can include both types of volumes, boot volumes, which are the system disks for your Compute instances, and block volumes for your data storage. You can use volume groups to create volume group backups and clones that are point-in-time and crash-consistent.

This simplifies the process to create time-consistent backups of running enterprise applications that span multiple storage volumes across multiple instances. You can then restore an entire group of volumes from a volume group backup.

To create a backup of the volume group

Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Volumes Groups.

In the Volume Groups list, click Create Volume Group Backup in the Actions menu for the volume group you want to create a backup for.



The Oracle Cloud Infrastructure Block Volume service lets you expand the size of block and boot volumes. Which three options below can you use to increase the size of your block volumes?

  1. Clone an existing volume to a new, larger volume
  2. You can only expand block volumes and not boot volumes
  3. Expand an existing volume in place with offline resizing
  4. Take a backup of your existing volume and restore from the volume backup to a larger volume
  5. Expand an existing volume in place with online resizing

Answer(s): A,C,D

Explanation:

The Oracle Cloud Infrastructure Block Volume service lets you expand the size of block volumes and boot volumes. You have three options to increase the size of your volumes:
steps to do this.

Restore from a volume backup to a larger volume. See Restoring a Backup to a New Volume and Restoring a Boot Volume.

Clone an existing volume to a new, larger volume. See Cloning a Volume and Cloning a Boot Volume.



Your company is moving an Internet-facing, 2-tier web application into Oracle Cloud Infrastructure. The application must have a highly available architecture.

Which two design options would you consider? (Choose two.)

  1. Configure a Dynamic Route Gateway in your VCN and make it highly available.
  2. Configure a NAT instance in your Virtual Cloud Network (VCN). Create a route rule by using the private IP of the NAT instance as a route target for all the private subnets in your VCN.
  3. Create an Internet Gateway and attach it to your VCN. Deploy public load balancer nodes into two Available Domains.
  4. Place all web servers behind a public load balancer.

Answer(s): C,D



You have multiple applications installed on a compute instance and these applications generate a large amount of log files. These log files must reside on the boot volume for a minimum of 15 days and must be retained for at least 60 days. The 60-day retention requirement is causing an issue with available disk space.

What are the two recommended methods to provide additional boot volume space for this compute instance? (Choose two.)

  1. Terminate the instance while preserving the boot volume. Create a new instance from the boot volume and select a DenseIO shape to take advantage of local NVMe storage.
  2. Create an object storage bucket and use a script that runs daily to move log files older than 15 days to the bucket.
  3. Create and attach a block volume to the compute instance and copy the log files.
  4. Create a custom image and launch a new compute instance with a larger boot volume size.
  5. Write a custom script to remove the log files on a daily basis and free up the space on the boot volume.

Answer(s): B,D

Explanation:

These log files must reside on the boot volume for a minimum of 15 days so you have to increase the boot Volume
