Which two statements are true regarding cloning a block volume?

  1. You can change the block volume performance when creating a clone
  2. You can clone block volumes across regions
  3. You can change the block volume size when creating a clone
  4. You can skip block volume encryption when creating a clone

Answer(s): A,C

Explanation:

You can create a clone from a volume using the Block Volume service. Cloning enables you to make a copy of an existing block volume without needing to go through the backup and restore process.

A cloned volume is a point-in-time direct disk-to-disk deep copy of the source volume, so all the data that is in the source volume when the clone is created is copied to the clone volume.

You can only create a clone for a volume within the same region, availability domain and tenant. You can create a clone for a volume between compartments as long as you have the required access permissions for the operation.
during create a clone you can do the following:

If you want to clone the block volume to a larger size volume, check Custom Block Volume Size (GB) and then specify the new size. You can only increase the size of the volume, you cannot decrease the size. If you clone the block volume to a larger size volume, you need to extend the volume's partition. See Extending the Partition for a Block Volume for more information.

If you want to change the elastic performance setting when cloning the volume, check Custom Block Volume Performance and select the elastic performance setting you want the volume clone to use. See Block Volume Elastic Performance for more information. You can also change the elastic performance setting after you have cloned the volume, see Block Volume Elastic Performance. If you leave Custom Block Volume Performance unchecked, the cloned volume will use the same elastic performance setting as the source volume.



Which storage would you use if your big data workload requires shared access and an NFS based interface?

  1. File Storage
  2. Storage Software Cloud Appliance
  3. Object Storage
  4. Archive Storage
  5. Block Volume

Answer(s): A

Explanation:

The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:

General Purpose File Storage: Access to an unlimited pool of file systems to manage growth of structured and unstructured data.

Big Data and Analytics: Run analytic workloads and use shared file systems to store persistent data.

Lift and Shift of Enterprise Applications: Migrate existing Oracle applications that need NFS storage, such as Oracle E-Business Suite and PeopleSoft.

Databases and Transactional Applications: Run test and development workloads with Oracle, MySQL, or other databases.

Backups, Business Continuity, and Disaster Recovery: Host a secondary copy of relevant file systems from on premises to the cloud for backup and disaster recovery purposes.

MicroServices and Docker: Deliver stateful persistence for containers. Easily scale as your container-based environments grow.

You have one database-style application that frequently makes many random reads and writes across the dataset.

Which storage offering supports this application?

  1. Object Storage Service
  2. Archive Storage Service
  3. File Storage Service
  4. Block Storage Service

Answer(s): D



Which two Oracle Cloud Infrastructure services use a Dynamic Routing Gateway?

  1. OCI FastConnect Public Peering
  2. Local Peering
  3. OCI FastConnect Private Peering
  4. Internet Gateway
  5. OCI IPSec VPN Connect

Answer(s): C,E

Explanation:

You can think of a DRG as a virtual router that provides a path for private traffic (that is, traffic that uses private IPv4 addresses) between your VCN and networks outside the VCN's region.

You use a DRG when connecting your existing on-premises network to your virtual cloud network (VCN) with one (or both) of these:

IPSec VPN

Oracle Cloud Infrastructure FastConnect (Private Only)

You also use a DRG when peering a VCN with a VCN in a different region:

Remote VCN Peering (Across Regions)
