Oracle MySQL HeatWave Implementation Associate Rel 1 認定 1z0-915-1 試験問題 (Q51-Q56):

質問 # 51
What must be enabled for using the point-in-time recovery feature in a DB system?

A. Delete protection
B. High availability
C. Automatic backups
D. HeatWave cluster

正解：C

解説：
To use the point-in-time recovery feature in a DB system,automatic backupsmust be enabled (Answer B).
* Point-in-Time Recovery: This feature allows you to restore your database to a specific point in time, which is crucial for recovering from accidental data loss or corruption.
* Automatic Backups: These provide the necessary backup data that can be used to restore the database to the desired point in time.

質問 # 52
Which two are benefits of read replicas? (Choose two.)

A. Reduce down time.
B. Reduce network latency.
C. Reduce query latency.
D. Speed up analytical queries.
E. Scale read queries.

正解：C、E

解説：
A:Reduce query latency: By distributing read queries across multiple replicas, the load on the primary instance is reduced, which can decrease query latency. D.Scale read queries: Read replicas allow scaling of read operations by providing additional instances to handle read queries, improving overall performance and throughput.

質問 # 53
You want to restore the backup of a stand-alone DB system to a new DB system.
Which two changes are allowed? (Choose two.)

A. Use a different shape for the new DB system.
B. Use a different tenancy for the new DB system.
C. Use a smaller data storage size for the new DB system.
D. Use a different subnet for the new DB system.
E. Use a different region for the new DB system.

正解：A、D

解説：
When restoring the backup of a stand-alone DB system to a new DB system, the following changes are allowed:
* Use a different subnet for the new DB system(Answer B): You can select a different subnet within the same VCN or a different VCN for the new DB system, providing flexibility in network configuration.
* Use a different shape for the new DB system(Answer C): You can choose a different compute shape for the new DB system, allowing you to scale the compute resources according to the requirements.

質問 # 54
You have successfully enabled high availability of a stand-alone DB system. Which is true?

A. The DB system provides new port numbers on the same endpoint to connect to the secondary instances for read-only connections.
B. The DB system has three instances running in different availability or fault domains.
C. The DB system performs load balancing by distributing client connections to all instances.
D. The DB system provides new endpoints to connect to the secondary instances for read-only connections.

正解：B

解説：
When high availability is enabled for a stand-alone DB system,the DB system has three instances running in different availability or fault domains(Answer D).
* High Availability Configuration: This setup involves creating multiple instances of the DB system across different availability or fault domains to ensure redundancy and minimize the risk of downtime due to hardware or network failures.
* Instances: Typically, there are three instances-one primary and two replicas-ensuring that the system can failover seamlessly if one instance goes down.

解説：
B:ENGINE=csv SECONDARY_ENGINE=lakehouse ENGINE_ATTRIBUTE='{"file": [{"region":
"us-ashburn-1", "namespace": "mytenant", "bucket": "bucket01", "name": "airport.csv"}] }': This table option defines a Lakehouse external table based on a CSV file. It specifies thecsvengine for the table and uses thelakehouseas the secondary engine, along with the file's location details in OCI Object Storage.
