Oracle Cloud Database Services 2025 Professional Sample Questions (Q60-Q65):

NEW QUESTION # 60
Which statement accurately describes the inherent trade-offs often associated with choosing a NoSQL database over a traditional relational database?

A. NoSQL databases universally guarantee stronger data consistency than relational databases, but at the expense of increased operational complexity.
B. NoSQL databases provide simplified querying capabilities using standard SQL, enhancing developer productivity and reducing the learning curve.
C. NoSQL databases typically sacrifice strict data consistency (ACID) to gain horizontal scalability and higher availability.
D. NoSQL databases offer superior data integrity and reduced operational overhead compared to relational databases, making them ideal for transactional systems.

Answer: C

Explanation:
Trade-offs with NoSQL Databases:
NoSQL databases are designed toscale horizontallyby adding more nodes rather than scaling vertically by increasing hardware capacity. To achieve this scalability andhigh availability, NoSQL systems often adopt theBASE model(Basically Available, Soft state, Eventually consistent) rather than the strictACID model (Atomicity, Consistency, Isolation, Durability) typical of relational databases.
* This means thatdata consistencymay be relaxed (eventual consistency) to allow faster reads and writes.
* These characteristics make NoSQL suitable forlarge-scale, distributed systemsbut less ideal for applications requiringimmediate consistency, such as banking systems.
Why the other options are incorrect:
* A:NoSQL does not guarantee stronger consistency than relational databases.
* C:NoSQL typically does not offer superior data integrity for transactional workloads.
* D:SQL-based querying is usually not available in NoSQL, as they often have their own query mechanisms.

NEW QUESTION # 61
Which two prerequisites are required before you can provision a MySQL HeatWave DB system?

A. A MySQL Enterprise Edition license.
B. A pre-configured MySQL database dump for initial data loading.
C. An OCI Compute instance to act as a client for the MySQL DB system.
D. A Virtual Cloud Network (VCN) with appropriately configured subnets.
E. A configured OCI Vault with encryption keys for database security.

Answer: A,D

Explanation:
VCN Requirement (B):
AVirtual Cloud Network (VCN)with appropriate subnets is essential to providenetwork connectivity and isolationfor the HeatWave DB system. It ensures secure data flow within the Oracle Cloud Infrastructure.
License Requirement (E):
Since HeatWave is anenterprise feature, it requires aMySQL Enterprise Edition license.Without this license, the HeatWave functionalities cannot be utilized.
Why the other options are incorrect:
* A:Data loading can be performed post-provisioning.
* C:While encryption can be configured, it is not a prerequisite.
* D:An OCI Compute instance may be used as a client but is not mandatory for provisioning.

NEW QUESTION # 62
Before migrating to MySQL HeatWave, what is the MOST important action to take regarding user accounts and privileges?

A. Merge all user accounts into a single 'admin' account.
B. Delete all user accounts except for the root account.
C. Ensure all user accounts and privileges are compatible with MySQL 8.0, and recreate any incompatible accounts on the target instance.
D. Migrate all user accounts to use external authentication (e.g., LDAP).
E. Reset all user passwords to default values.

Answer: C

Explanation:
B: Ensure all user accounts and privileges are compatible with MySQL 8.0:
* MySQL HeatWaveis based onMySQL 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 inpassword hashing algorithms,privilege structure, androle 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.

NEW QUESTION # 63
In a BaseDB environment configured with automatic backups, what happens to the automatic backups when the DB system is terminated?

A. The most recent automatic backup is retained, while older backups are deleted.
B. The retention of automatic backups after DB system termination is configurable during DB system creation.
C. All automatic backups are immediately and permanently deleted from object storage.
D. All automatic backups are retained in object storage for a period determined by the original backup retention policy.
E. Automatic backups are migrated to a lower-cost archive storage tier.

Answer: D

Explanation:
Backup Retention Policy:
When aBaseDB system is terminated, automatic backups are not immediately deleted. Instead, they remain stored inOCI Object Storagefor the duration specified by thebackup retention policythat was configured at the time of database creation.
* This approach ensures that data can be recovered even after the database instance itself is terminated.
* Administrators can manually delete backups if they are no longer needed, but they arenot automatically purged.
Why the other options are incorrect:
* A:Backups are not deleted instantly upon termination.
* B:All backups are retained as per the policy, not just the most recent.
* D:No automatic migration to archive tier occurs.
* E:Backup retention settings are defined during provisioning, but not dynamically configurable after termination.

NEW QUESTION # 64
Which component aids in assessing the readiness of a MySQL instance for migration to MySQL HeatWave, specifically identifying potential compatibility issues?

A. Oracle SQL Developer
B. Oracle Cloud Advisor
C. MySQL Workbench
D. MySQL Shell Upgrade Checker Utility
E. MySQL Enterprise Monitor

Answer: D

Explanation:
C: MySQL Shell Upgrade Checker Utility:
* The utility analyzes MySQL instances for compatibility with newer versions, such as MySQL 8.0 used by HeatWave.
* It checks for:
* Syntax differences
* Data type mismatches
* Deprecated features
* The tool outputs a report highlighting issues that may impact migration to HeatWave.
Why the other options are incorrect:
* A. MySQL Enterprise Monitor:Focuses on monitoring performance, not compatibility.
* B. Oracle SQL Developer:Primarily used for database development, not upgrade checks.
* D. Oracle Cloud Advisor:Provides cloud optimization recommendations, not MySQL compatibility checks.
* E. MySQL Workbench:A visual tool for database design and administration, not specifically for upgrade assessment.
