TeraData HCIA-Datacom V1.0 TDVAN5 Prüfungsfragen mit Lösungen (Q73-Q78):

73. Frage
A middle-tier application server logs on to the database as TrustedUser and submits requests on behalf of application end users. The server is shared by Finance and Human Resources groups and uses ProxyUser query band to identify end users to the database. Each group needs access to its own sensitive data, so the Administrator has created two separate roles with the appropriate permissions.
What is the best way to control access to each group's sensitive data?

A. Specify the appropriate role for each end user in a grant connect through statement.
B. Define the roles as external and use the ProxyRole query band to specify one role.
C. Include both roles in the grant connect through statement, and use ProxyRole in the query band to select the appropriate role.
D. Grant both roles to TrustedUser, and add the ProxyRole query band to specify one role.

Antwort: C

Begründung:
The GRANT CONNECT THROUGH statement allows the TrustedUser to act on behalf of multiple end users while securely connecting to the database. By granting both roles (Finance and Human Resources) in this statement, you allow the ProxyUser to switch between roles depending on the query band's ProxyRole value.
Using the ProxyRole query band, the application can specify which role (Finance or Human Resources) should be used for each specific request. This approach provides flexibility, as the application can dynamically assign the appropriate role to the user based on the query context.
Option A (Defining roles as external and using ProxyRole) wouldn't fully address the need to manage multiple roles dynamically for a shared server.
Option B (Granting both roles to TrustedUser) doesn't allow for flexible role switching on a per-request basis without the use of GRANT CONNECT THROUGH and could lead to over-granting of permissions.
Option C (Specifying a role for each end user in GRANT CONNECT THROUGH) isn't as flexible as allowing both roles to be used and dynamically selected through the query band.
Thus, Option D is the most appropriate solution, as it provides both security and flexibility, enabling the application to use the correct role based on the ProxyRole query band for each query submitted.

74. Frage
The Administrator has dropped a profile which was associated with a group of users.
What will happen when one of the users from the group logs on to the database?

A. SPOOL and DEFAULT DATABASE specifications for the dropped profile will still apply to the user.
B. Password attributes defined at the system level in DBCSecurityDefaultsV will apply
C. The system will show a warning message.
D. The default profile setting for the user will be reset to NULL.

Antwort: B

Begründung:
When a profile is dropped, the users who were associated with that profile will no longer have the specific resource and configuration settings defined by that profile. Instead, the system-level default settings, such as those specified in DBC.SecurityDefaultsV, will apply to the users. This includes password attributes and other system-wide settings.
Option A (The default profile setting for the user will be reset to NULL) is not accurate, as the system will revert to the default settings rather than leaving values unset.
Option C (The system will show a warning message) does not typically occur when a profile is dropped. The system will manage the transition without user-facing warnings at login.
Option D (SPOOL and DEFAULT DATABASE specifications for the dropped profile will still apply to the user) is incorrect because once the profile is dropped, its settings no longer apply to the users who were associated with it.
Thus, the correct outcome is that system-level attributes defined in DBC.SecurityDefaultsV will govern the users' settings moving forward.

75. Frage
Which Viewpoint portlet can an Administrator use to track the live progress of a long running QueryGrid query?

A. Today's Statistics
B. Query Spotlight
C. Query Monitor
D. Completed Queries

Antwort: C

Begründung:
The Query Monitor portlet provides real-time monitoring of active queries, including QueryGrid queries. It shows the live progress of the query, details about its execution, and allows administrators to monitor long-running queries as they are processed.
Option B (Query Spotlight) is more focused on detailed analysis of query performance issues but is typically used after a query has completed.
Option C (Today's Statistics) shows aggregated statistics and system-level metrics but doesn't provide live tracking of individual query progress.
Option D (Completed Queries) shows details about queries that have already finished, so it wouldn't be suitable for tracking an ongoing query.

76. Frage
Which option in READ_NOS will reduce the number of objects scanned by queries?

A. LOCATION
B. ACCESS_KEY
C. BUFFERSIZE
D. FULLSCAN

Antwort: A

Begründung:
The LOCATION option in READ_NOS is used to specify the exact path or directory in the external storage system, helping reduce the number of objects scanned by narrowing down the scope of the query to specific locations within the data source.
The other options:
BUFFERSIZE adjusts the size of the data buffer used in reading, but does not reduce the number of objects scanned.
ACCESS_KEY is used to authenticate access to the data but does not affect the number of objects scanned.
FULLSCAN would scan all objects and is the opposite of what is needed to reduce the number of objects scanned.

77. Frage
After a recent migration, a request has started to take significant time to complete. Upon a detailed investigation of the EXPLAIN plan, it is found that an accidental unconstrained product join on a very uniformly-distributed large table was the prime reason for the issue. The Administrator needs to use workload management to detect when this request is running.
Which criteria should the Administrator select for this issue?

A. CPU Utilization
B. AWT Wait Time
C. CPU Disk Ratio
D. CPU Skew

Antwort: D

Begründung:
CPU Skew is a metric that measures the uneven distribution of CPU usage across AMPs (Access Module Processors). In the case of an accidental unconstrained product join on a large, uniformly distributed table, certain AMPs may handle significantly more work than others, leading to high CPU Skew. This skew occurs because the product join results in an inefficient execution plan, where data from the large table is unnecessarily compared row-by-row with another table.
Option A (AWT Wait Time) refers to the time queries spend waiting for available AMP Worker Tasks, but it is not directly related to detecting the inefficiencies caused by product joins.
Option C (CPU Disk Ratio) measures the relationship between CPU usage and disk I/O. While it could indicate inefficiency, it doesn't directly pinpoint product join issues like CPU Skew does.
Option D (CPU Utilization) reflects overall CPU usage but doesn't indicate imbalance across AMPs, which is critical for detecting issues like product joins.
