NEW QUESTION # 74
Which are the two restrictions for an Always Free Autonomous Database? (Choose two.)
Answer: A,D
Explanation:
The Always Free tier of Autonomous Database has specific limits. The two correct restrictions are:
Maximum of two Always Free Databases per OCI tenancy (B): OCI’s Always Free tier allows up to two free ADB instances per tenancy (e.g., one ATP, one ADW). This limit ensures fair resource distribution across users. For example, you might create FREEATP1 (1 OCPU, 20 GB) and FREEADW1 (1 OCPU, 20 GB) in your tenancy, but a third free instance isn’t permitted—you’d need a paid upgrade. This is tracked by tenancy OCID, visible in the OCI console under “Limits.” Maximum of one OCPU per Database (D): Each Always Free ADB is capped at 1 OCPU, non-scalable, with 20 GB of storage. This restricts compute power (e.g., no auto-scaling to 3x like paid tiers), suitable for small workloads like dev/test apps. For instance, a free ATP instance runs a lightweight app with SELECT * FROM users, but can’t handle heavy concurrency due to the single OCPU.
The incorrect options are:
Supports only ATP as a workload type (A): False. Always Free supports both ATP (transactional) and ADW (warehouse) workload types, giving flexibility for OLTP or analytics (e.g., ATP for a web app, ADW for reports).
Oracle Application Express (APEX) not included (C): False. APEX is included in both free ATP and ADW instances, pre-installed and accessible via the OCI console (e.g., “Development” > “APEX”). You can build apps like a task tracker without extra cost.
These restrictions balance free access with resource constraints, encouraging upgrades for heavier use.
NEW QUESTION # 75
Which set of Oracle Cloud Infrastructure metrics is available only for Autonomous Database on Dedicated Infrastructure?
Answer: D
Explanation:
Autonomous Database on Dedicated Infrastructure provides unique metrics due to its Exadata underpinnings:
Correct Answer (C): “IOPS, Storage used by tablespace, Apply and Transport Lag” are specific to dedicated deployments:
IOPS: Measures input/output operations per second, reflecting Exadata storage performance.
Storage used by tablespace: Tracks storage allocation at the tablespace level, unique to dedicated infrastructure’s granular control.
Apply and Transport Lag: Relevant for Data Guard configurations, showing replication delays, available only in dedicated setups with standby databases.
Incorrect Options:
A: Transaction Count, Running Statements, and Sessions are general metrics available in both shared and dedicated environments.
B: CPU and Storage Utilization are standard across all Autonomous Database types.
D: Query Latency, User Calls, and Execute Count are also common metrics, not exclusive to dedicated infrastructure.
These metrics offer deeper insights into dedicated Exadata performance.
NEW QUESTION # 76
You are the admin user of an Autonomous Database instance. A new business analyst has joined the team and would like to explore the Autonomous Database tables using Autonomous Database’s Data Tools. Which step should you perform to enable the new team member?
Answer: D
Explanation:
Full Detailed In-Depth Explanation:
To enable a business analyst to use Autonomous Database Data Tools (e.g., Data Load, SQL Developer Web), specific permissions are required:
REST-enabled user: Data Tools rely on REST APIs, necessitating a user with REST support enabled.
Connect and object privileges: These allow database access and interaction with tables.
DWROLE role: This predefined role grants a comprehensive set of privileges for data analysis tasks in Autonomous Data Warehouse (ADW), including SELECT, EXECUTE, and data loading capabilities.
Evaluating the options:
A: Correct. Creating a REST-enabled user with connect/object privileges and granting DWROLE ensures full access to Data Tools, tailored for ADW exploration.
B: Incorrect. Default privileges are minimal and insufficient for Data Tools usage.
C: Incorrect. While connect, resource, and object privileges provide basic access, they lack the REST enablement and DWROLE’s specific analysis permissions.
D: Incorrect. An IDCS (Identity Cloud Service) user is for OCI authentication, not database-level access, and this step overcomplicates the process.
NEW QUESTION # 77
When you are increasing the number of OCPUs in your Autonomous Database, what does its status show?
Answer: C
Explanation:
Scaling OCPUs in an Autonomous Database triggers a specific status update. The correct answer is:
SCALING IN PROGRESS (D): When you increase (or decrease) the number of OCPUs, the database status in the OCI console changes to “SCALING IN PROGRESS.” This indicates that the system is actively adjusting the compute resources, a process that typically completes in a few minutes with no downtime for active transactions.
The incorrect options are:
UPSCALE IN PROGRESS (A): “Upscale” is not an official status term used by Oracle for this operation.
RESIZING IN PROGRESS (B): While “resizing” might intuitively fit, Oracle specifically uses “SCALING IN PROGRESS” for CPU adjustments.
UPLIFT IN PROGRESS (C): “Uplift” is not a recognized status in the context of Autonomous Database scaling.
This status reflects Oracle’s terminology for dynamic scaling.
NEW QUESTION # 78
While provisioning a dedicated Autonomous Container Database, which backup retention period CANNOT be implemented?
Answer: B
Explanation:
Full Detailed In-Depth Explanation:
When provisioning an Autonomous Container Database (ACD) on dedicated infrastructure, Oracle provides specific options for backup retention periods to balance data recovery needs with storage costs. According to the official Oracle documentation, the available backup retention periods for a dedicated ACD are:
7 days: This is the default retention period for a newly provisioned ACD.
15 days: An option for extended retention beyond the default.
60 days: The maximum supported retention period for ACDs, offering the longest recovery window.
The option of 120 days is not supported as a backup retention period for an Autonomous Container Database. This limitation is due to the design of the Autonomous Database service, which caps retention at 60 days to optimize storage and performance on dedicated Exadata infrastructure. Attempting to set a retention period beyond 60 days is not an available choice during provisioning. Users must select a retention period that meets their recovery point objectives (RPO) within these constraints, noting that longer retention increases storage usage and associated costs.
