Question 1

Which backup method utilizes minimal network resources and complies with security best practices?

A : Offline backup using the HeatWave Administration Console

B : Online backup with RMAN to Object Storage via a public endpoint

C : Online backup with the HEATWAVE_FULL_BACKUP tool to a local NVMe disk

D : Online backup with Data Guard to another HeatWave service in a separate VCN

Answer: A

Question 2

What additional configuration is needed alongside IAM integration to enable users to connect to the MySQL HeatWave DB system using IAM credentials?

A : Configure a Bastion session with the DB system-s private subnet as the target resource.

B : Set up SSH key authentication on the DB system and specify the key pair during IAM user creation.

C : Create a dedicated security list rule allowing inbound traffic from the OCI Console IP address range.

D : Configure virtual private cloud (VPC) peering between the DB system-s VCN and the IAM service VCN.

E : Assign the heatwave_user role to IAM users intended to access the HeatWave layer.

Answer: E

Question 3

You have provisioned a MySQL HeatWave DB system in your VCN and want to connect using MySQL Shell from your local machine. Which additional configuration is necessary to establish a secure connection?

A : Configure a bastion service in your VCN and access the DB system through the bastion instance-s internal IP address.

B : Enable SSH public key authentication on the DB system and utilize the \connect command with the public endpoint IP address and private key.

C : Grant your user account the connect privilege for the database and use the mysql command with the DB system-s public endpoint IP address and username/password.

D : Create a route table entry in your VCN routing traffic from your local machine-s subnet to the DB system-s subnet directly.

E : Configure a VPN connection between your local machine and the VCN containing the DB system and connect using the private endpoint IP address.

Answer: B

Question 4

You're migrating a high-volume transactional database to MySQL HeatWave using replication. To minimize downtime on the source system, what replication configuration would be MOST effective?

A : Configure continuous replication with minimal lag between source and target.

B : Implement snapshot replication with periodic data synchronization at scheduled intervals.

C : Set up asynchronous replication with manual data synchronization when downtime is acceptable.

D : Utilize statement-based replication with delayed commit on the HeatWave target system.

Answer: B

Question 5

Your application is configured to connect to the primary instance of your MySQL HeatWave service. You want to switch to a read replica for read-heavy workloads. Which approach is recommended for minimizing application downtime during the switch?

A : Update the application-s connection string directly to point to the read replica endpoint.

B : Modify the read replica load balancer configuration to route all traffic to the desired replica.

C : Implement a DNS failover mechanism to automatically switch to the read replica in case of the primary outage.

D : Use a database proxy with read replica awareness to transparently redirect read queries to the replica.

Answer: D
