質問 # 149
Which is an Autonomous Database critical event?
正解：B
解説：
Critical events in Autonomous Database are those requiring immediate attention due to potential security or operational impacts:
Correct Answer (D): “Admin Password Warning” is a critical event because it indicates the admin password is nearing expiration (typically within 7 days). If not updated, it could lock out administrative access, posing a security and availability risk.
Incorrect Options:
A: “Maintenance Begin” is an operational event, not critical, as it’s planned and managed by Oracle.
B: “Database Connection” is a routine activity, not an event requiring urgent action.
C: “Schedule Maintenance Warning” is informational, not critical, as it’s a precursor to planned maintenance.
E: “New Maintenance Schedule” is administrative, not an immediate threat.
This ensures timely response to security-critical situations.
質問 # 150
Which statement is false about Autonomous Database Oracle Client Credentials (Wallets)?
正解：D
解説：
Oracle Client Credentials (wallets) are essential for secure connections to the Autonomous Database. The false statement is:
The Wallet for the Autonomous Database is the same as the TDE wallet (A): This is incorrect. The Oracle Client Credential wallet (used for client authentication and connection security) is distinct from the Transparent Data Encryption (TDE) wallet (used to encrypt data at rest within the database). The client wallet contains certificates and keys for mutual TLS (mTLS) authentication, while the TDE wallet manages encryption keys for data security. They serve different purposes and are not the same.
The correct statements are:
You must have an Oracle Client Credential wallet in order to connect to the Autonomous Database (B): True. The wallet is required for mTLS, which is the default authentication method for Autonomous Databases, ensuring secure connections.
In addition to the Oracle Client Credential Wallet, a user must have a username and password in order to connect to the Autonomous Database (C): True. Alongside the wallet, a database username and password are needed for full authentication (mTLS + user credentials).
The Oracle Client Credential file is downloaded as a ZIP file (D): True. When downloaded from the Oracle Cloud Infrastructure (OCI) console, the wallet is provided as a ZIP file containing configuration files like tnsnames.ora and certificates.
This distinction is critical for understanding security mechanisms in Autonomous Database.
質問 # 151
How do you change the tablespace quota for user MTHEO on an Autonomous Database on Shared Infrastructure?
正解：D
解説：
Full Detailed In-Depth Explanation:
In Autonomous Database on Shared Infrastructure, tablespace quotas are managed using standard SQL commands, as administrative packages like DBMS_CLOUD_ADMIN are restricted in this environment. The correct method is:
ALTER USER MTHEO QUOTA UNLIMITED ON TABLESPACE DATA: This command directly modifies the user’s quota on the DATA tablespace, which is the default tablespace in Autonomous Database. “UNLIMITED” removes any storage restrictions.
Analysis of options:
A: Incorrect. DBMS_CLOUD_ADMIN is used in dedicated infrastructure for advanced administrative tasks, not shared infrastructure for quota changes.
B: Correct. This is the standard SQL syntax supported in shared infrastructure.
C: Incorrect. ALTER TABLESPACE modifies tablespace properties, not user quotas, and isn’t applicable here.
D: Incorrect. ALTER DATABASE syntax is invalid for user quotas; it’s for database-wide settings.
質問 # 152
Autonomous Database's auto scaling feature allows your database to use up to three times the current base number of OCPU cores at any time. As demand increases, auto scaling automatically increases the number of cores in use. Likewise, as demand drops, auto scaling automatically decreases the number of cores in use. Which statement is FALSE regarding the auto scaling feature?
正解：A
解説：
Auto scaling in Autonomous Database dynamically adjusts OCPU usage up to three times the base allocation. Let’s evaluate each statement:
Correct Answer (C): “The base number of OCPU cores allocated to a database is not guaranteed” is false. The base OCPU count, set during provisioning or manual scaling, is always guaranteed as the minimum available resource, even with auto scaling enabled. Auto scaling only increases usage above this baseline when needed.
True Statements:
A: On dedicated Exadata, the max cores for auto scaling are constrained by available free cores not used by other databases, ensuring resource fairness.
B: The total cores in the Exadata instance define the upper limit for any database’s auto scaling capacity.
D: Auto scaling is not enabled by default (must be explicitly activated) and can be toggled on/off, though this statement’s phrasing could be clearer—it’s still true in context.
This guarantees predictable minimum performance while allowing flexibility for peak loads.
質問 # 153
Which statement is FALSE about setting up compartment quotas?
正解：D
解説：
Compartment quotas in Oracle Cloud Infrastructure (OCI) manage resource allocation:
Correct Answer (D): “Compartment quotas cannot be set on the root compartment” is false. Quotas can be applied to any compartment, including the root compartment, to limit resource usage tenancy-wide. While direct quotas on the root are less common (child compartment quotas are typically used), it’s technically possible via OCI policies.
True Statements:
A: Quotas offer flexible resource limits (e.g., OCPUs, storage) via policy statements.
B: Parent compartment quotas take precedence over child quotas, enforcing hierarchical control.
C: Managing quotas requires appropriate IAM permissions (e.g., manage quotas), ensuring security.
This flexibility supports granular resource management across the tenancy.
