Oracle Autonomous Database Cloud 2025 Professional Sample Questions (Q89-Q94):
NEW QUESTION # 89
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. MEDIUM
- B. TPURGENT
- C. LOW
- D. TP
Answer: B
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 # 90
Which four file formats are supported when loading data from Cloud Storage?
- A. DOC
- B. CSV
- C. JSON
- D. AVRO
- E. DDL
- F. Parquet
Answer: B,C,D,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 # 91
Which two statements are correct about Autonomous Data Warehouse on Shared Exadata Infrastructure?
- A. Compression is enabled by default. Autonomous Data Warehouse uses Hybrid Columnar Compression for all tables by default.
- B. Parallelism is not enabled by default.
- C. You have direct access to the database node.
- D. Oracle Database Result Cache is enabled by default for all SQL statements.
Answer: A,D
Explanation:
Let's evaluate each statement about Autonomous Data Warehouse (ADW) on Shared Exadata Infrastructure:
A . Oracle Database Result Cache is enabled by default for all SQL statements: True. ADW enables the Result Cache by default to improve query performance by storing frequently accessed results in memory.
B . You have direct access to the database node: False. ADW is a fully managed service; users do not have direct access to underlying nodes, which Oracle manages for patching, scaling, and security.
C . Parallelism is not enabled by default: False. Parallelism is enabled by default in ADW to optimize large analytical queries across multiple CPUs.
D . Compression is enabled by default. Autonomous Data Warehouse uses Hybrid Columnar Compression for all tables by default: True. Hybrid Columnar Compression (HCC) is applied automatically to reduce storage and enhance query performance.
Thus, A and D are correct, reflecting ADW's default performance optimizations.
NEW QUESTION # 92
Which file is NOT a component of the client credentials wallet used to connect to an Oracle Autonomous Database?
- A. sqlnet.ora
- B. keystore.jks
- C. ewallet.p12
- D. protocol.ora
- E. cwallet.sso
Answer: D
Explanation:
The client credentials wallet for connecting to an Oracle Autonomous Database contains specific files required for secure connectivity. These files are downloaded from the OCI Console when you generate a wallet:
Correct Answer (A): protocol.ora is not a standard component of the client credentials wallet. It is typically used in traditional Oracle Database setups to define protocol parameters (e.g., TCP vs. IPC), but in Autonomous Database, such details are managed by Oracle and embedded within other wallet files like ewallet.p12.
Included Files:
B . ewallet.p12: Contains the encrypted private key and certificates for authentication.
C . sqlnet.ora: Specifies network configuration details (e.g., wallet location, encryption settings).
D . keystore.jks: A Java KeyStore file for Java-based applications to authenticate with the database.
E . cwallet.sso: Supports single sign-on (SSO) by storing service credentials.
Additionally, tnsnames.ora and truststore.jks (not listed here but mentioned in the original) are also part of the wallet, defining service aliases and trusted certificates, respectively. Since protocol.ora is not included or required, it's the correct exclusion.
NEW QUESTION # 93
Which statement is true about the use of Access Control Lists (ACLs) with an Autonomous Database on Shared Infrastructure?
- A. When you restore a database, the existing ACLs are not overwritten by the restore.
- B. An ACL can only be set during the creation of an Autonomous Database on Shared Infrastructure
- C. ACLs can only be used with private endpoints
- D. An ACL can be set up for an IP Address or a virtual cloud network but not both at the same time
Answer: A
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.
