Oracle Cloud Database Services 2025 Professional Sample Questions (Q96-Q101):

NEW QUESTION # 96
Which statement accurately describes the inherent trade-offs often associated with choosing a NoSQL database over a traditional relational database?

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

Answer: B

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 # 97
Which of the following characteristics is most indicative of a NoSQL database's focus on scalability and availability over strict consistency?

A. Partitioning and replication of data across multiple nodes.
B. Support for complex joins and transactions across multiple tables.
C. Reliance on a centralized, single-instance architecture.
D. Enforcement of strict referential integrity constraints.

Answer: A

Explanation:
C: Partitioning and replication of data across multiple nodes:
* NoSQL databases typically prioritizehorizontal scalabilityby distributing data across multiple nodes.
* Replicationensures data availability even if one node fails.
* This approach leads toeventual consistencyrather than strict ACID compliance.
* The system can continue to operate despite some nodes being offline, maintaining high availability.
Why the other options are incorrect:
* A. Complex joins and transactions:Typical of relational databases prioritizing consistency.
* B. Strict referential integrity:More common in SQL databases requiring ACID transactions.
* D. Centralized architecture:Opposite of scalable, distributed NoSQL models.

NEW QUESTION # 98
Which characteristic is MOST indicative of an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM) deployment compared to using Autonomous Database?

A. Shared Exadata infrastructure with other tenants for cost optimization.
B. Automated patching and upgrades handled by Oracle.
C. Direct control over the operating system and database configuration.
D. Automatic scaling of compute and storage resources based on workload demands.

Answer: C

Explanation:
Direct Control in BaseDB VM:
In aBaseDB VM deployment, users haveroot-level access to the operating systemand can directly manage the database configuration. This contrasts withAutonomous Database, where Oracle handles most administrative tasks, including patching and resource scaling.
* BaseDB VM offersflexibility for custom configurationsand control overOS-level operations.
* This is particularly useful for environments requiringcustom scripts, configurations, or database tuning.
Why the other options are incorrect:
* A:Autonomous Database features automatic patching, not BaseDB VM.
* B:Exadata infrastructure is typically associated withAutonomous Databaserather than VM-based BaseDB.
* D:Automatic scaling is a feature of Autonomous Database, not BaseDB.

NEW QUESTION # 99
Which Oracle Cloud Infrastructure (OCI) service is PRIMARILY used to store backups created from a BaseDB database?

A. OCI Block Volume
B. OCI Data Transfer Service
C. OCI Archive Storage
D. OCI Object Storage
E. OCI File Storage

Answer: D

Explanation:
C: OCI Object Storage:
* The primary storage service for database backups within OCI.
* Offers high durability, availability, and scalability.
* Integrated with Oracle's automated backup solutions for BaseDB.
* Suitable for both short-term and long-term storage of database backups.
Why the other options are incorrect:
* A. OCI Block Volume:Used for primary database storage, not long-term backups.
* B. OCI File Storage:Typically used for file system-based workloads, not for database backups.
* D. OCI Archive Storage:Suitable for long-term archival but not the primary backup destination.
* E. OCI Data Transfer Service:Used for bulk data migration into OCI, not for backup storage.

NEW QUESTION # 100
Before migrating to MySQL HeatWave, what is the MOST important action to take regarding user accounts and privileges?

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

Answer: A

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.
