NEW QUESTION # 32
A Business Analyst joined your organization and wants to explore the database tools. When restoring or cloning an Autonomous Database (ADB), you must select a backup that is at least how old?
Answer: B
Explanation:
Full Detailed In-Depth Explanation:
When restoring or cloning an Autonomous Database (ADB), Oracle enforces a minimum backup age to ensure data consistency and integrity. The official Oracle documentation specifies that backups used for these operations must be at least 24 hours old. This requirement exists because:
Backups need time to complete and stabilize, ensuring all transactions are fully committed and the backup is consistent.
Recent backups (e.g., less than 24 hours old) may still be in progress or lack full verification, risking incomplete or corrupted restores/clones.
Options B (5 minutes), C (2 hours), and D (1 day) are either too short or redundant:
5 minutes and 2 hours: Too recent, violating the 24-hour rule.
1 day: Matches 24 hours but is less precise than the explicit “24 hours” phrasing in the documentation.
For the Business Analyst’s exploration, they can access tools like SQL Developer Web or Data Load via the OCI Console under the “Tools” tab, but this question focuses on the backup age constraint, making A the best answer.
NEW QUESTION # 33
What is a best practice when planning and instituting access controls for your Autonomous Dedicated environment regarding subnets, compartments, and user groups?
Answer: A
Explanation:
When designing access controls for an Autonomous Dedicated environment, Oracle recommends redundancy and separation for security and manageability:
Correct Answer (D): “Create at least 2 of each resource” (subnets, compartments, user groups) is a best practice:
Subnets: Using at least two subnets (e.g., one public, one private) enhances security by segregating traffic and provides failover options if one subnet encounters issues.
Compartments: Multiple compartments allow logical separation (e.g., dev, test, prod), simplifying access control and resource management.
User Groups: At least two groups (e.g., admins, developers) streamline permission assignments and reduce the risk of over-privileging users.
Incorrect Options:
A: OCI allows multiple subnets and compartments; restricting to one limits flexibility and security.
B: There’s no such limitation; multiple resources are supported and encouraged.
C: A VCN with only public subnets contradicts security best practices, as private subnets are critical for database isolation.
This approach aligns with Oracle’s guidance for secure and scalable deployments.
NEW QUESTION # 34
When cloning from a backup, what is the earliest timestamp of the backup allowed in Autonomous Database?
Answer: D
Explanation:
Cloning from a backup in Autonomous Database has a minimum age requirement:
Correct Answer (A): The earliest timestamp allowed is 2 hours after the backup is created. This ensures data consistency by allowing time for any in-flight transactions or writes to stabilize in the backup, preventing incomplete or corrupted clones.
Incorrect Options:
B: 24 hours is the default retention period, not the minimum cloning age.
C, D: 1 hour and 30 minutes are too short; they don’t meet the 2-hour consistency window.
This policy safeguards clone integrity.
NEW QUESTION # 35
Which three are Oracle-recommended best practices for Autonomous Database alarms? (Choose three.)
Answer: A,B,C
Explanation:
Oracle recommends best practices for effective alarm management:
Correct Answer (A): Suppress alarms during investigations prevents notification overload while troubleshooting, focusing attention on the issue.
Correct Answer (C): Select the correct alarm interval for your metric ensures timely alerts without excessive noise (e.g., 1-minute intervals for critical metrics).
Correct Answer (D): Routinely tune your alarms adjusts thresholds and settings to match workload changes, maintaining relevance.
Incorrect Option:
B: Creating multiple alarm metrics isn’t explicitly recommended; quality and tuning of alarms matter more than quantity.
These practices optimize monitoring efficiency.
NEW QUESTION # 36
Which workload type does the Autonomous Database on dedicated infrastructure service currently support?
Answer: B
Explanation:
Autonomous Database on dedicated infrastructure supports multiple workload types. The correct answer is:
ATP and ADW (C): Autonomous Database on dedicated infrastructure supports both Autonomous Transaction Processing (ATP) for OLTP workloads (high concurrency, low latency) and Autonomous Data Warehouse (ADW) for analytical workloads (high throughput, complex queries). This dual support allows flexibility within a single dedicated Exadata infrastructure.
The incorrect options are:
Autonomous Transaction Processing only (A): Incorrect, as ADW is also supported.
Hybrid Columnar Compression (B): HCC is a data compression feature, not a workload type; it’s used within ADW but doesn’t define the workload.
Autonomous Data Warehouse only (D): Incorrect, as ATP is also supported.
This versatility is a key feature of dedicated deployments.
