IT Architects will learn how to integrate dedicated database environments within their cloud strategy.

Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q54-Q59):

NEW QUESTION # 54
Which two statements are true about the Oracle Cloud Infrastructure (OCI)? (Choose two.)

A. Regions are dependent on other regions and must be located within 5 thousand kilometers of each other.
B. Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region.
C. A single fault domain can be associated with multiple regions and availability domains.
D. An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region.

Answer: B,D

Explanation:
Oracle Cloud Infrastructure (OCI) is designed with a hierarchical structure to ensure high availability and fault tolerance:
Correct Answer (B): "An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region" accurately describes OCI's architecture. A region is a standalone geographic area (e.g., US East), and availability domains (ADs) are isolated data centers within that region, enhancing resilience.
Correct Answer (D): "Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region" reflects OCI's design for fault isolation. ADs are physically separate, minimizing the risk of cascading failures.
Incorrect Options:
A: Regions are independent, not dependent, and there's no 5,000-kilometer restriction; they are globally distributed for latency and redundancy purposes.
C: Fault domains are subdivisions within an AD, not across regions or ADs, ensuring resource isolation within a single AD.
This structure supports robust disaster recovery and high availability.

NEW QUESTION # 55
Which option should you use to create a graph with Graph Studio?

A. Tables in an Autonomous Database instance
B. NoSQL configuration
C. Graph analytics algorithms
D. A graph license key
E. Graph created by a special tool downloaded from oracle.com

Answer: A

Explanation:
Graph Studio in Autonomous Database enables graph creation and analysis:
Correct Answer (A): "Tables in an Autonomous Database instance" are used to create graphs. Graph Studio builds property graphs from relational tables by defining vertices (nodes) and edges (relationships) based on existing data, leveraging the database's schema.
Incorrect Options:
B: Graph analytics algorithms analyze existing graphs, not create them.
C: NoSQL configuration is unrelated; Graph Studio uses relational data.
D: No external tool from oracle.com is required; Graph Studio is a built-in feature.
E: A license key isn't a creation method; graph features are included with Autonomous Database.
This integrates graph capabilities with existing data.

NEW QUESTION # 56
Which statement is true about the use of Access Control Lists (ACLs) with an Autonomous Database on Shared Infrastructure?

A. An ACL can only be set during the creation of an Autonomous Database on Shared Infrastructure
B. ACLs can only be used with private endpoints
C. When you restore a database, the existing ACLs are not overwritten by the restore.
D. An ACL can be set up for an IP Address or a virtual cloud network but not both at the same time

Answer: C

Explanation:
ACLs control network access to Autonomous Database on Shared Infrastructure:
Correct Answer (B): "When you restore a database, the existing ACLs are not overwritten by the restore" is true. ACLs are part of the database's network configuration, preserved during restore operations to maintain security settings.
Incorrect Options:
A: ACLs can include both IP addresses and VCN CIDR blocks simultaneously; they're not mutually exclusive.
C: ACLs apply to public endpoints, not just private ones, to restrict access.
D: ACLs can be modified post-creation, not just at provisioning time.
This ensures consistent security post-restore.

NEW QUESTION # 57
Which four file formats are supported when loading data from Cloud Storage?

A. JSON
B. DDL
C. DOC
D. CSV
E. AVRO
F. Parquet

Answer: A,D,E,F

Explanation:
Full Detailed In-Depth Explanation:
Supported formats:
A: False. DDL is a language, not a data format.
B: True. AVRO is supported for structured data.
C: True. Parquet is optimized for analytics.
D: False. DOC is not supported.
E: True. JSON is flexible for semi-structured data.
F: True. CSV is widely used for tabular data.

NEW QUESTION # 58
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_proddb
C. BACKUP_PRODDB
D. backup_dbsrv1

Answer: A

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.
