exacli

NO.33 Which three actions can you perform on a DB system that has an Oracle Data Guard association with a standby database?
(Choose all correct answers)

If the primary database becomes unavailable, then you can use Oracle Data Guard to fail over the standby database to the primary role.

You can write on both primary and standby databases because DB system standby databases in Oracle Cloud Infrastructure Database are logical standbys.

You can terminate a primary database DB system.

You can use the reinstate command to return a failed database into standby role after correcting the cause of failure.

You can switch over the primary database to the standby role, perform maintenance on the standby database, and then switch it back to the primary role.

Backup network

Client network

Control plane network

Cloud operations network

EBS Storage

NO.40 You want to move an Exadata Cloud@Customer VM cluster to a different OCI compartment for increased isolation from other teams that use Exadata. What happens when you use the console to do this?

The VM cluster and associated databases will move to the new compartment. All other resources will remain in the existing compartment.

After it is deployed, a VM cluster cannot change compartments.

The vm cluster, compute nodes, and associated databases will move compartments. All other resources will remain in the existing compartment.

The vM cluster, compute nodes, and underlying Exadata infrastructure will move to the new compartment. All other resources remain the same.

NO.41 What TWO reasons do you need a minimum of three storage cells when using Exadata Cloud Service?
(Choose all correct answers)

for high availability

for Fast Start Failover of storage cells
