TeraData TDVAN5 Exam Syllabus Topics:

Topic
Details

Topic 1

Database Management: This section tests the skills of database administrators in managing access rights and advanced analytic functions. It covers logging benefits, privilege types, and the impact of changing global parameters on user sessions.

Topic 2

Performance Management: This section of the exam evaluates the skills of TeraData database administrators. It focuses on strategies for managing statistics, implementing DBQL logging, and using performance data to troubleshoot and resolve system issues.

Topic 3

Monitoring Vantage: This section of the exam measures the skills of IT professionals such as system administrators. It covers how to effectively use Viewpoint to investigate system conditions, monitor external queries, and administer both Viewpoint and monitored systems.

TeraData HCIA-Datacom V1.0 Sample Questions (Q39-Q44):

NEW QUESTION # 39
On a Vantage system, the data load process has recently become much slower than normal and is now running for two hours in low concurrency. During the time the process is running, the Administrator measured the following average values from ResUsage:
System CPU busy = 75%
WIO = 25%
Inter-AMP parallelism = 90%
Average BYNET usage = 10%
Which resource is most constrained?

A. CPU
B. I/O
C. Parallelism
D. BYNET

Answer: B

Explanation:
WIO (Work in I/O) is at 25%, which indicates that the system is spending a significant amount of time waiting for I/O operations to complete. This suggests that I/O is the most constrained resource in this scenario. A high WIO typically points to I/O bottlenecks, causing delays in processes like data loading.
The other resources appear to be less constrained:
CPU: The system is busy with 75% CPU usage, which indicates the CPU has available capacity (not fully utilized).
BYNET: With 10% BYNET usage, there is no indication of network congestion.
Parallelism: Inter-AMP parallelism is at 90%, which suggests that parallel processing is functioning well and not the bottleneck.
Thus, the data load slowdown is likely due to I/O constraints, making I/O the most constrained resource in this case.

NEW QUESTION # 40
An Administrator notices that a system appears to be near capacity and needs to get information about Input/Output Token Allocations (IOTA) for each workload.
How can this information be obtained?

A. Check DBC.ResSpmaView
B. Check DBC.ResSldvView
C. Check DBC.ResSpdskView
D. Check DBC.ResSpsView

Answer: D

Explanation:
The DBC.ResSpsView view provides resource usage information, including I/O-related metrics for workloads. It includes I/O Token Allocations (IOTA), which are essential for monitoring and managing system capacity.
The other options do not specifically provide I/O Token Allocation data:
DBC.ResSpmaView is used for monitoring memory allocations.
DBC.ResSpdskView focuses on disk space usage.
DBC.ResSldvView is related to logging device information.
Therefore, DBC.ResSpsView is the correct view to check for I/O Token Allocations.

NEW QUESTION # 41
An Administrator has set up security constraints on columns holding sensitive data through the use of profiles. A user, with an appropriate profile, then issues a select against this sensitive data.
Which type of privilege is being used?

A. Ownership
B. Assigned
C. Inherited
D. Automatic

Answer: C

Explanation:
Inherited privileges are those that a user acquires based on their membership in a profile or role. In this case, the user has been assigned a profile that grants access to sensitive data, meaning the privilege to access that data is inherited through the profile.
Option B (Ownership) refers to the privileges that the creator (owner) of a database object has over that object, but in this case, the user is accessing data through a profile, not ownership.
Option C (Automatic) would suggest that the privilege is granted automatically without the need for an explicit assignment or inheritance, which doesn't apply here because the privileges are coming from a profile.
Option D (Assigned) refers to direct privileges granted to a user individually, but in this scenario, the user is accessing data through a profile, which means the privileges are inherited rather than directly assigned.

NEW QUESTION # 42
Which data type could support an index definition on a table?

A. Large Object (LOB)
B. Geospatial
C. DATASET
D. JSON

Answer: B

Explanation:
Geospatial data types can support index definitions in Teradata. Geospatial indexing is used to optimize spatial queries, enabling efficient searching and retrieval of data based on spatial coordinates (e.g., points, lines, polygons).
The other data types do not support indexing directly:
DATASET: This is used to store unstructured or semi-structured data and typically does not support indexing.
JSON: While JSON data can be used within Teradata, it is typically not indexed in the traditional sense.
Large Object (LOB): LOBs (like BLOBs or CLOBs) are generally used for storing large amounts of unstructured data and are not suitable for indexing due to their size and nature.

NEW QUESTION # 43
A user runs a number of large, complex queries that regularly generate insufficient memory errors. The Administrator increases the value of the MaxParseTreeSegs DBS control field in order to allocate more parse tree segments to the parser for parsing requests.
Which action must be taken before the queries will run without memory errors?

A. Purge the request cache.
B. The user should log out and log back in to a new session.
C. Execute an OUTPUT command.
D. Execute an Alter METHOD command for

Answer: B
