問題 #132
Which file is NOT a component of the client credentials wallet used to connect to an Oracle Autonomous Database?
答案:E
解題說明:
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.
問題 #133
During the provisioning of an Autonomous Database on dedicated hardware, what should the database administrator select to determine where the Autonomous Database is created on the dedicated infrastructure?
答案:C
解題說明:
Full Detailed In-Depth Explanation:
When provisioning an Autonomous Database (ADB) on dedicated infrastructure, the placement within the infrastructure is critical:
A . Listener endpoint: Incorrect. This is for connectivity, not placement.
B . Client Credentials wallet: Incorrect. This is for secure connections, not determining location.
C . The container database in which the Autonomous instance should run: Correct. On dedicated infrastructure, an Autonomous Container Database (ACD) hosts multiple ADB instances. Selecting the ACD during provisioning determines where the ADB resides, affecting resource allocation and isolation.
D . The compartment: Incorrect. Compartments organize resources in OCI, but multiple ACDs can exist within a compartment, so this doesn’t pinpoint the exact location.
Choosing the ACD is a key provisioning step for dedicated deployments.
問題 #134
Given the steps:
Create Oracle Machine Learning User
Create Projects
Create Workspaces
Create Notebooks
Run SQL Scripts
Which two steps are out of order when working with Oracle Machine Learning?
答案:A,B
解題說明:
Full Detailed In-Depth Explanation:
The correct sequence for Oracle Machine Learning (OML) is:
Create Oracle Machine Learning User: First step to enable OML access.
Create Workspaces: Containers for organizing projects.
Create Projects: Groups for related notebooks within a workspace.
Create Notebooks: Environments for coding and analysis.
Run SQL Scripts: Executed within notebooks.
In the given list, Create Projects (2) comes before Create Workspaces (3), which is reversed. Workspaces must exist before projects. Thus, C and D are out of order.
問題 #135
Which statement is FALSE about Autonomous Database maintenance on Dedicated Infrastructure?
答案:D
解題說明:
Full Detailed In-Depth Explanation:
Maintenance on dedicated infrastructure:
A: True. You can adjust maintenance windows for container databases.
B: False. Exadata Infrastructure maintenance (e.g., OS, grid patching) is separate from container database patching, which occurs independently.
C: True. Oracle reschedules missed maintenance to the next quarter.
D: True. Infrastructure maintenance occurs quarterly.
問題 #136
Which command should you issue to enable application continuity on Oracle Autonomous Database on Shared Infrastructure?
答案:A
解題說明:
Application Continuity ensures seamless failover for applications:
Correct Answer (B): EXEC DBMS_CLOUD_ADMIN.ENABLE_APP_CONT('<service_name>'); is the correct command for Autonomous Database on Shared Infrastructure. It enables Application Continuity for a specific service (e.g., tpurgent), leveraging the DBMS_CLOUD_ADMIN package designed for cloud-specific administration.
Incorrect Options:
A: ALTER SESSION only affects the current session, not persistent database-wide settings.
C, D: ALTER DATABASE and ALTER SYSTEM are not supported in Autonomous Database’s managed environment; Oracle restricts such commands.
This ensures application resilience in a managed setup.
