Question 6 of 42

You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle Cloud Infrastructure (OCI).

The storage volumes include boot volumes and block volumes for your data storage. You need to create backup for the boot volumes that will be done daily and a backup for the block volumes that will be done every six hours.

How can you meet this requirement?

Group the boot volumes into a volume group and create a custom backup policy. Group the block volumes and create a custom backup policy.

Create on-demand full backups of block volumes, and create custom images from the boot volumes. Using a function to run at specific time to start the back up process.

Group together multiple storage volumes in a volume group and create volume group backups.

Create clones of all boot volumes and block volumes one at a time.

Correct Answer: A

To meet the requirement of backing up boot volumes daily and block volumes every six hours, it is necessary to create separate custom backup policies for each type of volume. Grouping the boot volumes into a volume group and creating a custom backup policy allows the daily backups, while grouping the block volumes and creating a separate custom backup policy allows the backups every six hours. This approach ensures that the different backup schedules are maintained as required.

Question 7 of 42

You created a virtual cloud network (VCN) with three private subnets. Two of the subnets contain application servers and the third subnet contains a DB System. The application requires a shared file system so you have provisioned one using the file storage service (FSS).

You also created the corresponding mount target in one of the application subnets. The VCN security lists are properly configured so that the application servers can access file storage service (FSS). The security team changed the settings for the DB System to have read-only access to the file system. However, when they went to test this they are unable to access the (FSS).

What change should you make to allow access to (FSS)?

Create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet.

Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateful.

Create an instance principal for the DB System. Write an Identity and Access Management (IAM) policy that allows the instance principal read-only access to the file storage service.

Modify the security list associated with the subnet where the mount target resides. Change the ingress rules corresponding to the DB System subnet to be stateless.

Correct Answer: A

To allow access to the File Storage Service (FSS), create an NFS export option that allows READ_ONLY access where the source is the CIDR range of the DB System subnet. This ensures that clients in the DB System subnet have the necessary permissions to access the file system in read-only mode. Without this export option, even if the security lists are properly configured, the file system access will be restricted.

Question 8 of 42

A financial firm is designing an application architecture for its online trading platform that must have high availability and fault tolerance.

Their solutions architect configured the application to use an Oracle Cloud Infrastructure Object Storage bucket located in the US West (us-phoenix-1) region to store large amounts of financial data. The stored financial data in the bucket must not be affected even if there is an outage in one of the Availability Domains or a complete region.

What should the architect do to avoid any costly service disruptions and ensure data durability?

Create a lifecycle policy to regularly send data from Standard to Archive storage.

Create a new Object Storage bucket in another region and configure lifecycle policy to move data every 5 days.

Copy the Object Storage bucket to a block volume.

Create a replication policy to send data to a different bucket in another OCI region.

Correct Answer: D

To avoid costly service disruptions and ensure data durability even in the case of an outage in one of the Availability Domains or a complete region, the architect should create a replication policy to send data to a different bucket in another OCI region. This approach ensures that the data is stored in multiple geographic locations, providing high availability and fault tolerance.

Question 9 of 42

Which statement is NOT true about the Oracle Cloud Infrastructure Object Storage service?

Object lifecycle rules can be used to either archive or delete objects.

Object versioning is enabled at namespace level.

Immutable option for data stored in the Object Storage can be set via retention rules.

Object storage resources can be shared across tenancies.

Correct Answer: B

Object versioning is not enabled at the namespace level; it is enabled at the bucket level. This distinction makes the statement that object versioning is enabled at the namespace level incorrect, whereas the other statements about lifecycle rules, retention rules, and sharing resources across tenancies are accurate for Oracle Cloud Infrastructure Object Storage service.

Question 10 of 42

As a solution architect, you are showcasing the Oracle Cloud Infrastructure (OCI) Object Storage feature about Object Versioning to a customer.

Which statement is true in regards to OCI Object Storage Versioning?

Objects are physically deleted from a bucket when versioning is enabled.

Object versioning does not provide data protection against accidental or malicious object update, overwrite, or deletion.

By default, object versioning is disabled on a bucket.

A bucket that is versioning-enabled can have only and always will have the latest version of the object in the bucket.

Correct Answer: C

By default, object versioning is disabled on a bucket. When object versioning is not enabled, new versions of objects are not created upon updates or overwrites, and only the current version of each object is stored. Enabling versioning on a bucket allows you to retain, retrieve, and restore different versions of objects, providing protection against accidental or malicious updates or deletions.
