NEW QUESTION # 20
Which Autonomous Database Service is NOT used to connect to an Autonomous Transaction Processing instance?
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
Autonomous Transaction Processing (ATP) supports specific service names for connectivity:
TPURGENT: High-priority service with 200 concurrent statements per OCPU and parallelism.
MEDIUM: Balanced service for moderate workloads.
HIGH: Optimized for reporting/batch jobs with high parallelism.
LOW: Low-priority service for minimal resource use.
TP: General-purpose transactional service.
TPPERFORMANT is not a recognized service name in ATP documentation, making A the correct answer.
NEW QUESTION # 21
What is the difference between Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP) databases?
Answer: A
Explanation:
ADW and ATP are tailored for different workloads:
Correct Answer (C): “Only ADW uses columnar compression by default” is true. ADW employs Hybrid Columnar Compression (HCC) for analytics, optimizing storage and query performance, while ATP uses row-based storage for transactional workloads (though HCC can be enabled manually).
Incorrect Options:
A: Both ADW and ATP manage optimizer statistics automatically.
B: Autoscaling is supported by both ADW and ATP.
D: Automatic backups are standard for both.
This reflects their design focus: ADW for analytics, ATP for transactions.
NEW QUESTION # 22
Which two statements are true about Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for Autonomous Data Guard? (Choose two.)
Answer: A,D
Explanation:
Autonomous Data Guard enhances high availability for Autonomous Database. The two true statements are:
RPO is 0 minutes for an automatic failover (C): Recovery Point Objective (RPO) measures potential data loss. With Autonomous Data Guard, the standby database is synchronously replicated with the primary, ensuring zero data loss (RPO = 0) during an automatic failover, as all transactions are mirrored in real-time.
RTO is 2 minutes for an automatic failover (E): Recovery Time Objective (RTO) measures downtime during failover. For Autonomous Data Guard, Oracle specifies an RTO of approximately 2 minutes for automatic failovers, reflecting the time to detect failure and promote the standby to primary.
The incorrect options are:
RTO and RPO are adjustable through the OCI console (A): RTO and RPO are fixed by the Autonomous Data Guard architecture and cannot be manually adjusted via the OCI console.
RPO is adjustable, but RTO is always 5 minutes (B): RPO is not adjustable (it’s 0 due to synchronous replication), and RTO is not fixed at 5 minutes; it’s typically 2 minutes for automatic failover.
RTO and RPO are 0 minutes for manual failovers (D): Manual failovers (switchovers) have an RTO greater than 0 (typically a few minutes) due to manual initiation, though RPO remains 0 with synchronous replication.
These values ensure minimal disruption and data loss.
NEW QUESTION # 23
In the Autonomous Database on Dedicated Infrastructure service, what does the fleet administrator use to control OCPU utilization?
Answer: C
Explanation:
Fleet administrators manage resource utilization in Autonomous Database on Dedicated Infrastructure:
Correct Answer (B): Compartment quotas are used to set limits on OCPU usage across multiple database instances within a compartment. This OCI feature allows administrators to define maximum resource allocations, ensuring efficient use and cost control at a tenancy level.
Incorrect Options:
A: Oracle Machine Learning notebooks are for analytics, not resource control.
C: SQL Developer Web Console manages individual database tasks, not fleet-wide OCPU limits.
D: Resource Manager settings apply to individual instances, not fleet-level quotas.
Compartments provide a scalable, tenancy-wide control mechanism.
NEW QUESTION # 24
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?
Answer: B
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.
