B. Delete an active manual backup when point-in-time recovery is enabled on the DB system.
C. Restore an active backup to a new DB system in another region.
D. Move an active backup to another compartment.
E. Change the retention period of an active manual backup.

Answer: C,D,E

Explanation:
Three operations that can be performed on a MySQL HeatWave backup are:
B:Change the retention period of an active manual backup: You can adjust how long the backup is retained.
C:Restore an active backup to a new DB system in another region: You can restore backups to different regions for disaster recovery or data migration. E.Move an active backup to another compartment: You can organize and manage backups by moving them to different compartments.

NEW QUESTION # 63
You want to deploy a high-availability MySQL DB system in a region with multiple availability domains.
Which two types of subnet provide maximum redundancy? (Choose two.)

A. A private AD-specific subnet
B. A private regional subnet
C. A public regional subnet
D. A public AD-specific subnet

Answer: B,C

Explanation:
To deploy a high-availability MySQL DB system in a region with multiple availability domains, the following types of subnets provide maximum redundancy:
* A private regional subnet(Answer B): This type of subnet spans all availability domains in the region, ensuring high availability and fault tolerance.
* A public regional subnet(Answer C): Similar to the private regional subnet, a public regional subnet spans all availability domains, providing maximum redundancy and accessibility.

* OCI Networking Documentation
* MySQL High Availability Documentation

NEW QUESTION # 64
You want to restore a stand-alone DB system to a high-availability DB system with a point-in-time recovery.
Which three are required? (Choose three.)

A. Point-in-time recovery must be enabled before the point in time to which you want to restore.
B. Every user table must have a primary key.
C. An automatic backup taken before the selected point in time must be available.
D. The stand-alone DB system must remain active during the restore.
E. A manual backup taken before the selected point in time must be available.

Answer: A,C,E

Explanation:
To restore a stand-alone DB system to a high-availability DB system with point-in-time recovery, the following are required:
B:Point-in-time recovery must be enabled before the point in time to which you want to restore: Point-in-time recovery (PITR) must be enabled beforehand to allow restoration to a specific point in time. C.An automatic backup taken before the selected point in time must be available: You need an automatic backup from before the desired restore point. D.A manual backup taken before the selected point in time must be available:
Manual backups are also essential to ensure you can restore to the desired point in time.

NEW QUESTION # 65
The first query has an estimated cost of 100,000,000 and is offloaded to a HeatWave cluster for execution:
SELECT flightno, departure, country FROM flight JOIN airport_geo ON 'from'=airport_id; The second query has an estimated cost of 10,000 and is NOT offloaded to the Heatwave cluster for execution:
SELECT DISTINCT country FROM airport_geo ORDER BY country;
Which two methods can offload the second query to the Heatwave cluster for execution? (Choose two.)

A. SET optimizer_trace="enabled=on";
B. CALL sys.heatwave_load('["airport_geo"]');
C. SET secondary_engine_cost_threshold=1000;
D. SET use_secondary_engine=FORCED;
E. CALL sys.heatwave_advisor(JSON_OBJECT("auto_enc", JSON_OBJECT("mode", "recommend")));

Answer: C,D

Explanation:
To offload the second query to the HeatWave cluster for execution, you can use the following methods:
* SET use_secondary_engine=FORCED(Answer A): This forces the use of the HeatWave secondary engine for query execution, regardless of the estimated cost.
* SET secondary_engine_cost_threshold=1000(Answer B): This lowers the cost threshold for queries to be offloaded to the HeatWave cluster, allowing queries with lower estimated costs to be offloaded.
Steps:
* Before running the second query, executeSET use_secondary_engine=FORCED;to force the offloading of queries to HeatWave.
* Alternatively, executeSET secondary_engine_cost_threshold=1000;to adjust the cost threshold, making the second query eligible for offloading.

NEW QUESTION # 66
You have successfully provisioned a MySQL DB system on Oracle Cloud Infrastructure by using OCI Console. You have installed the standard MySQL client libraries and MySQL Shell on your workstation that is not connected to any VPN, FastConnect, or SSH tunnel.
You CANNOT connect directly to the DB system endpoint from your workstation connected to the Internet.
What is the reason?

A. MySQL DB system allows only SSL-encrypted connections.
B. MySQL DB system endpoint does not have a public IP address.
C. MySQL DB system allows only connections through a proxy server.
D. MySQL DB system cannot use the standard MySQL client libraries.

Answer: B

Explanation:
If you cannot connect directly to the MySQL DB system endpoint from your workstation connected to the Internet, the reason is thatMySQL DB system endpoint does not have a public IP address(Answer B).
* Private Subnet: The MySQL DB system is provisioned in a private subnet, which means it is not directly accessible from the Internet.
* Network Accessibility: To access the DB system, you need to establish a secure connection via a VPN, FastConnect, or SSH tunnel.
