Oracle Cloud Database Services 2025 Professional Sample Questions (Q92-Q97):

NEW QUESTION # 92
Oracle NoSQL Database Cloud Service's key-value model is well-suited for certain types of applications.
Which of the following application scenarios would most directly benefit from the key-value data model's characteristics?

  • A. A social media platform needing to store and retrieve individual user profiles and their associated data quickly.
  • B. An application requiring complex analytical queries and joins across multiple related datasets.
  • C. An enterprise resource planning (ERP) system managing intricate relationships between various business entities.
  • D. A financial system requiring strict transactional integrity and complex relationships between accounts and transactions.
  • E. A content management system needing to enforce a rigid schema for all documents and their metadata.

Answer: A

Explanation:
B: Social Media Platform:
* Social media applications require quick retrieval of user profiles based on unique IDs.
* The key-value model supports fast lookups and simple data associations, ideal for user-centric data.
* The flexibility of storing user attributes in a single document enhances performance and scalability.
Why the other options are incorrect:
* A. Complex analytical queries:Relational or analytical databases are better suited.
* C. Financial systems:Require ACID compliance and complex joins, not suitable for key-value models.
* D. Content management:Typically requires a more structured approach, better handled by document databases.
* E. ERP systems:Need relational integrity and complex schema support.


NEW QUESTION # 93
You are tasked with monitoring the I/O performance of an Exadata Database Service (ExaDB) using the exadcli utility. You need to retrieve detailed statistics on Smart Flash Cache usage, including read and write operations, at the storage cell level. Which exadcli command will provide the most comprehensive information?

  • A. exadcli list metriccurrent -cell -metricname "IOPS,MBPS"
  • B. exadcli list metrichistory -cell -metricname "flashcache_read_iops,flashcache_write_iops"
  • C. exadcli list metricdetail -cell -metricname "flashcache.*"
  • D. exadcli list metriccurrent -cell -metricname "cell.*"

Answer: C

Explanation:
Detailed Flash Cache Monitoring:
The commandexadcli list metricdetail -cell -metricname "flashcache.*"provides acomprehensive overviewof all metrics related toSmart Flash Cache. This includes bothread and write operations, hit ratios, and IOPS statistics.
* Themetricdetailoption retrieves in-depth data, crucial for performance troubleshooting.
* Theflashcache.*wildcard captures all relevant metrics associated with the Flash Cache subsystem.
Why the other options are incorrect:
* A:Limited to current IOPS and throughput, not specifically flash cache.
* C:Too broad, as it includes general cell metrics.
* D:Focuses only on historical read/write IOPS, not comprehensive.


NEW QUESTION # 94
Which is NOT a typical function provided by a NoSQL Database Cloud Service SDK related to data operations?

  • A. Automatically optimizing query execution plans for best performance.
  • B. Serializing and deserializing data between application objects and database records.
  • C. Handling pagination of query results.
  • D. Constructing requests to insert, update, or delete data records.

Answer: A

Explanation:
A: Automatically optimizing query execution plans for best performance.
Query Optimization:
* Query optimization is handled by the database engine itself, not the SDK.
* SDKs are primarily focused on providing an interface for data operations, not on internal query optimization.
Why the other options are typical SDK functions:
* B. Constructing requests:SDKs facilitate building and sending data manipulation requests.
* C. Serializing data:Converting data between application objects and database formats is a core SDK function.
* D. Handling pagination:SDKs often include utilities to manage large result sets.


NEW QUESTION # 95
What primary security mechanism within Oracle NoSQL Database Cloud Service governs access to individual tables, dictating which users or groups can perform specific actions?

  • A. Identity and Access Management (IAM) policies
  • B. Database Vault
  • C. Virtual Cloud Network (VCN) security lists
  • D. Transparent Data Encryption (TDE)

Answer: A

Explanation:
IAM Policies:
Oracle NoSQL Database Cloud Service usesOCI IAM policiesto control access to tables. These policies specify who (user or group) can perform what actions (read, write, delete) on specific database resources. This centralized approach allows for granular permission control, supporting the principle ofleast privilege.
IAM policies are configured at theOCI tenancy leveland can be customized to define access based onusers, groups, and dynamic groups. They are essential for maintaining secure data access, especially in multi- tenant environments.
Why the other options are incorrect:
* A:VCN security lists control network traffic, not table-level access.
* C:Database Vault is for fine-grained access control within traditional Oracle Databases, not NoSQL.
* D:TDE handles data encryption, not access management.


NEW QUESTION # 96
Before migrating to MySQL HeatWave, what is the MOST important action to take regarding user accounts and privileges?

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

Answer: B

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.
