Question 1

Before migrating to MySQL HeatWave, what is the MOST important action to take regarding user accounts and privileges?

AReset all user passwords to default values.

BEnsure all user accounts and privileges are compatible with MySQL 8.0, and recreate any incompatible accounts on the target instance.

CDelete all user accounts except for the root account.

DMigrate all user accounts to use external authentication (e.g., LDAP).

EMerge all user accounts into a single 'admin' account.

Correct : B

B . Ensure all user accounts and privileges are compatible with MySQL 8.0:

MySQL HeatWave is based on MySQL 8.0, so compatibility is crucial.

User accounts and privileges must be updated to match the security and syntax requirements of MySQL 8.0.

If any incompatibility is detected, the accounts should be recreated on the target HeatWave instance.

Typical issues include changes in password hashing algorithms, privilege structure, and role management.

Why the other options are incorrect:

A . Resetting passwords to default: Risky from a security perspective and unnecessary.

C . Deleting user accounts except root: This drastically limits access and disrupts database operations.

D . External authentication (LDAP): Not mandatory or relevant to compatibility with HeatWave.

E . Merging accounts into a single 'admin': Violates best practices for user management and security.

Question 2

Which two requirements must be met first to create an Exadata Database Service Instance?

AYou only need a VCN and Universal Cloud Credits.

BYou need to define the VCN, Private Client subnet, and Service Backup subnet.

CYou need to define the VCN, Private Client subnet, and Private Backup subnet.

DThere are no prerequisites for creating an Exadata Database Service instance.

EYou need to create an Exadata Infrastructure and VM Cluster resource.

Correct : C, E

C . Define VCN, Private Client subnet, and Private Backup subnet:

These network components are necessary to ensure secure connectivity and backup configurations.

The VCN (Virtual Cloud Network) provides network isolation.

The Private Client subnet enables secure client connections.

The Private Backup subnet is required for secure access to OCI Object Storage for backups.

E . Create Exadata Infrastructure and VM Cluster resource:

Exadata Infrastructure represents the physical hardware.

VM Cluster resource defines compute and storage resources for the databases.

Both must be set up before provisioning the actual database instance.

Why the other options are incorrect:

A . VCN and Universal Cloud Credits: Insufficient; more configuration is needed.

B . Service Backup subnet: Incorrect, it should be a Private Backup subnet.

D . No prerequisites: Incorrect; prerequisites include both network and infrastructure setup.
