1Z0-1072-22 Exam Questions & Answers

Correct Answer: B

Remote VCN peering is the process of connecting two VCNs in different regions (but the same tenancy ).

The peering allows the VCNs' resources to communicate using private IP addresses without routing the

traffic over the internet or through your on-premises network. Without peering, a given VCN would need an

internet gateway and public IP addresses for the instances that need to communicate with another VCN in

a different region.

At a high level, the Networking service components required for a remote peering include:

-Two VCNs with non-overlapping CIDRs, in different regions that support remote peering. The VCNs must

be in the same tenancy.

-A dynamic routing gateway (DRG) attached to each VCN in the peering relationship. Your VCN already

has a DRG if you're using an IPSec VPN or an Oracle Cloud Infrastructure FastConnect private virtual

circuit.

A remote peering connection (RPC) on each DRG in the peering relationship.

A connection between those two RPCs.

Supporting route rules to enable traffic to flow over the connection, and only to and from select subnets in

the respective VCNs (if desired).

Supporting security rules to control the types of traffic allowed to and from the instances in the subnets that

need to communicate with the other VCN.

Correct Answer: AC

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.

Correct Answer: D

When creating a compartment, you must provide a name for it (maximum 100 characters, including letters, numbers, periods, hyphens, and underscores) that is unique within its parent compartment. You must also provide a description, which is a non-unique, changeable description for the compartment, from 1 through 400 characters. After creating a compartment, you need to write at least one policy for it, otherwise no one can access it (except administrators or users who have permissions set at the tenancy level). When creating a compartment inside another compartment, the compartment inherits access permissions from compartments higher up its hierarchy. When you create an access policy, you need to specify which compartment to attach it to. This controls who can later modify or delete the policy. Depending on how you've designed your compartment hierarchy, you might attach it to the tenancy, a parent, or to the specific compartment itself.
