Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q40-Q45):

NEW QUESTION # 40
You need to create a new database by using the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI) with the following requirements: Autonomous Transaction Processing, License Included, Shared Infrastructure. Which parameter would you NOT use?

A. db-type
B. is-dedicated
C. license-model
D. db-workload

Answer: A

Explanation:
Creating an Autonomous Transaction Processing (ATP) database via OCI CLI requires specific parameters:
Correct Answer (A): db-type is not a standard OCI CLI parameter for provisioning an Autonomous Database. The CLI uses parameters like db-workload to specify the type (e.g., ATP).
Used Parameters:
B: is-dedicated must be set to false for shared infrastructure.
C: db-workload is set to OLTP for ATP.
D: license-model is set to LICENSE_INCLUDED per the requirement.
The correct command might look like: oci db autonomous-database create --db-name <name> --db-workload OLTP --license-model LICENSE_INCLUDED --is-dedicated false.

NEW QUESTION # 41
DBSRV1 is an Autonomous Database with the display name PRODDB. You plan to take manual backups of this database periodically. What must be the name of the bucket that will be used to store manual backups?

A. backup_dbsrv1
B. BACKUP_DBSRV1
C. backup_proddb
D. BACKUP_PRODDB

Answer: B

Explanation:
Manual backups in Autonomous Database are stored in OCI Object Storage, and the bucket name follows a strict convention. The correct name is:
BACKUP_DBSRV1 (D): For manual backups, ADB uses a bucket named BACKUP_<DB_UNIQUE_NAME> (all uppercase). Here, DBSRV1 is the database's unique name (not the display name PRODDB), so the bucket must be BACKUP_DBSRV1. This bucket is automatically created by Oracle when you initiate a manual backup via the OCI console (e.g., "Create Manual Backup" button) or API (e.g., oci db autonomous-database backup create). For example, backing up DBSRV1 on March 18, 2025, stores files like backup_DBSRV1_20250318.dmp in this bucket. The unique name ensures uniqueness across the tenancy, as display names (e.g., PRODDB) might not be unique but the DB_UNIQUE_NAME is system-assigned and distinct.
The incorrect options are:
backup_proddb (A): This uses the display name proddb and lowercase, violating the BACKUP_<UNIQUE_NAME> uppercase convention.
BACKUP_PRODDB (B): While uppercase, it uses the display name PRODDB, not the unique name DBSRV1, so it's incorrect. Display names are for human readability, not system identification.
backup_dbsrv1 (C): This uses lowercase and lacks the exact BACKUP_ prefix format, failing Oracle's naming rule.
The rigid naming ensures consistency and automation in ADB's backup system.

NEW QUESTION # 42
You have a requirement to create an Autonomous Transaction Processing database that can support at least 200 concurrent statements per OCPU as well as parallelism. Which service will you need to connect to?

A. LOW
B. TP
C. TPURGENT
D. MEDIUM

Answer: C

Explanation:
Full Detailed In-Depth Explanation:
Autonomous Transaction Processing (ATP) offers predefined service levels with varying concurrency and parallelism capabilities:
MEDIUM: Supports up to 50 concurrent statements per OCPU, with no parallelism by default. Unsuitable for the requirement.
TPURGENT: Supports up to 200 concurrent statements per OCPU and enables manual parallelism. This meets both requirements (concurrency ≥ 200 and parallelism), making it the correct choice.
LOW: Supports only 25 concurrent statements per OCPU, with no parallelism. Insufficient for the requirement.
TP: Supports 125 concurrent statements per OCPU, with no parallelism by default. Falls short of the 200 concurrency threshold.
TPURGENT is designed for high-concurrency, time-sensitive workloads, providing the necessary resources and flexibility for parallel query execution, aligning perfectly with the specified needs.

NEW QUESTION # 43
Which can be used to ensure that your Autonomous Database is accessible only from a given set of IPs?

A. Security List
B. Access Control List
C. IPSec List
D. IP Vault

Answer: B

Explanation:
Restricting access to an Autonomous Database to specific IPs involves network security controls. The correct answer is:
Access Control List (C): In Autonomous Database, an Access Control List (ACL) defines which IP addresses or CIDR blocks (e.g., 192.168.1.0/24) can connect to the database. You configure this via the OCI console under the ADB's "Access Control List" settings, adding rules like "Allow TCP from 10.0.0.0/16 on port 1522." This applies to public endpoints (shared infrastructure) or private endpoints with additional network rules, ensuring only authorized IPs can initiate connections. For example, a company might restrict access to its office VPN range, blocking all other traffic. ACLs work at the database level, complementing VCN security.
The incorrect options are:
Security List (A): Security Lists operate at the VCN subnet level, controlling traffic to all resources in the subnet (e.g., ingress TCP 1522 to an ADB subnet). While useful, they're broader than ADB-specific ACLs, which target the database instance directly, making ACLs the precise answer here.
IP Vault (B): There's no "IP Vault" in OCI. This might confuse OCI Vault (for secrets), but it doesn't manage IP access.
IPSec List (D): IPSec secures traffic via VPNs, not IP allowlisting for database access. It's unrelated to ADB connectivity restrictions.
ACLs provide a database-specific, user-friendly way to enforce IP-based access control.

NEW QUESTION # 44
Which statement is FALSE about Oracle Autonomous JSON Database?

A. It supports NoSQL-style, document-centric applications.
B. JSON data is stored natively in the database.
C. You can promote Autonomous JSON Database to Autonomous Transaction Processing.
D. There is a 20 GB limit on JSON collection.

Answer: D

Explanation:
Full Detailed In-Depth Explanation:
The Oracle Autonomous JSON Database is a specialized service for managing JSON data with NoSQL-style capabilities. Let's evaluate each statement:
A . It supports NoSQL-style, document-centric applications: True. Autonomous JSON Database is designed for NoSQL workloads, supporting document-based applications via APIs like SODA (Simple Oracle Document Access).
B . There is a 20 GB limit on JSON collection: False. The Oracle documentation does not specify a fixed 20 GB limit on JSON collections. Storage capacity is determined by the overall database size, which can scale dynamically without a specific cap on individual collections. This makes B the false statement.
C . JSON data is stored natively in the database: True. JSON data is stored in a binary format optimized for performance, avoiding the need for parsing or transformation during access.
D . You can promote Autonomous JSON Database to Autonomous Transaction Processing: True. Oracle allows promoting an Autonomous JSON Database to ATP, enabling relational capabilities if application needs evolve.
The false claim about a 20 GB limit likely stems from confusion with other database constraints, but no such restriction exists for JSON collections in Autonomous JSON Database.
