NEW QUESTION # 92
You created an Autonomous Database without auto scaling. Which two ways can you enable auto scaling? (Choose two.)
Answer: B,D
Explanation:
Enabling auto scaling on an existing Autonomous Database can be done without unnecessary complexity:
Correct Answer (A): “Click Scale Up/Down and select the Auto Scaling checkbox” is the simplest GUI method. In the OCI Console, navigate to the database, select “Scale Up/Down,” and enable the auto scaling option, allowing up to 3x the base OCPUs dynamically.
Correct Answer (C): “Use a REST call to enable Auto Scaling” leverages the OCI REST API to update the database configuration with the isAutoScalingEnabled parameter set to true. This is ideal for programmatic control.
Incorrect Options:
B: Shutting down the instance is unnecessary; auto scaling can be enabled while the database is running.
D: Multiple REST calls, including shutdown and restart, overcomplicate the process when a single API call suffices.
These methods ensure minimal disruption and efficient resource management.
NEW QUESTION # 93
Which three Oracle Cloud Infrastructure (OCI) resources do you need to configure before provisioning your Autonomous Database with a private endpoint? (Choose three.)
Answer: A,C,E
Explanation:
Provisioning an Autonomous Database with a private endpoint requires:
Correct Answer (A): Network Security Group (NSG) defines traffic rules for the private endpoint, restricting access to specific sources.
Correct Answer (B): VCN (Virtual Cloud Network) provides the network foundation, hosting the subnet and endpoint.
Correct Answer (E): Subnet (private) contains the database’s private endpoint, isolating it from public access.
Incorrect Options:
C: Security Lists apply to subnets but are optional with NSGs, which are preferred for finer control.
D: Route Table is needed for connectivity (e.g., to a NAT Gateway), but not strictly required for the private endpoint itself.
These ensure secure, private access.
NEW QUESTION # 94
For fleet admins to access dedicated Exadata infrastructure, which policy should be assigned?
Answer: C
Explanation:
Fleet administrators managing dedicated Exadata infrastructure in Oracle Autonomous Database require broad permissions across all Autonomous Database resources, including those on dedicated infrastructure.
Correct Answer (B): The policy Allow group adb-admins to manage autonomous-database-family in tenancy grants comprehensive management rights over the entire Autonomous Database family, including dedicated Exadata infrastructure. The autonomous-database-family resource type encompasses all Autonomous Database resources (shared and dedicated) within the tenancy, making it suitable for fleet admins.
Incorrect Options:
A: Limits permissions to databases with the OLTP workload type (Autonomous Transaction Processing), excluding Data Warehouse (DW) or other types on dedicated infrastructure.
C: Restricts access to DW workload types only, omitting OLTP and other configurations.
D: Grants permissions only to autonomous-database resources, which may not fully cover dedicated infrastructure components like Autonomous Container Databases or Exadata Infrastructure.
This policy ensures fleet admins have the necessary scope to manage all aspects of dedicated deployments.
NEW QUESTION # 95
What predefined user is created when provisioning an Autonomous Database (ADB) instance to which you connect to create other users and grant roles?
Answer: B
Explanation:
When provisioning an Autonomous Database (ADB) instance, Oracle creates a default administrative user with extensive privileges. The correct user is:
ADMIN (B): The ADMIN user is automatically created during ADB provisioning and serves as the primary administrative account. It has full privileges to manage the database, including creating users, granting roles, and performing administrative tasks (e.g., scaling, backups). For example, after provisioning an ADB via the OCI console, you’d connect as ADMIN using the password you set, then run commands like: CREATE USER analyst1 IDENTIFIED BY "password"; GRANT CONNECT, RESOURCE TO analyst1;. This user is the entry point for initial configuration and ongoing management, authenticated via the client wallet for secure access (e.g., sqlplus admin/password@adb_high). The ADMIN user is distinct from traditional Oracle users like SYS because ADB’s managed nature limits direct system-level access, funneling administration through ADMIN.
The incorrect options are:
SYS (A): In traditional Oracle databases, SYS is the superuser with ultimate control (e.g., owning the data dictionary). In ADB, however, SYS exists but is locked and inaccessible to customers due to the fully managed environment—Oracle manages system-level operations, and users connect as ADMIN instead.
DWDEV (C): There’s no predefined DWDEV user in ADB. This might confuse with roles like DWROLE (for Data Warehouse developers), but no such user is created by default.
SCOTT (D): SCOTT is a sample user from older Oracle versions (with tables like EMP and DEPT), not created in ADB. It’s irrelevant in this modern, managed context.
The ADMIN user’s role ensures customers can manage ADB without needing Oracle’s intervention, aligning with its autonomous design.
NEW QUESTION # 96
While provisioning a dedicated Autonomous Container Database, which backup retention period CANNOT be implemented?
Answer: C
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.
