Actual exam question for Oracle's 1Z0-1093-25 exam

Question #: 1
Topic #: 2

Which two actions must you undertake when configuring the networking to provide network connectivity for a MySQL HeatWave DB System instance?

AEnsure the subnet used has a Service Gateway to Oracle Services, such as Object Storage, so that patching can be applied.

BDeploy the MySQL HeatWave DB System to a public subnet to allow external connectivity for users.

CCreate ingress security rules in the VCN security list or Network Security Groups (NSGs) to allow traffic to the MySQL HeatWave DB System.

DConfigure a dynamic routing gateway for inter-VCN connectivity.

ECreate egress security rules in the VCN security list or Network Security Groups (NSGs) to block access from the MySQL HeatWave DB System to any outside network.

Show Suggested Answer

Suggested Answer: A, C

A . Service Gateway for Oracle Services:

Ensures the HeatWave DB System can access Oracle Services like Object Storage without using the public internet.

Essential for tasks such as patching and backups.

C . Ingress security rules:

Allows necessary traffic to reach the HeatWave DB System.

Typically, rules will permit MySQL port (3306) and any application-specific ports.

Configured using VCN security lists or NSGs.

Why the other options are incorrect:

B . Public subnet deployment: Exposes the database to the internet, which is a security risk.

D . Dynamic routing gateway: Not mandatory unless inter-VCN connectivity is specifically required.

E . Blocking egress entirely: Restricting all outbound traffic can prevent necessary updates and communication with Oracle services.

I think we should ensure the subnet has a Service Gateway for patching.
