QUESTION: 11

An Administrator has been given a task to generate a list of users who have not changed their password in the last 90 days.
Which DBC view should be used to generate this list?

DBC.LOGONOFFV
DBC.USERSV
DBSECURITYDEFAULTSV
DBC.ACCESSLOGV

Answer(s): B

Explanation:

DBC.USERSV contains information about users, including the passwordlastmodified column, which records the date and time the user last changed their password. By querying this view, the Administrator can identify users who have not updated their password within the specified time frame (in this case, 90 days).
Option A (DBC.LOGONOFFV) logs user logon and logoff events, but it does not track password changes.
Option C (DBC.SECURITYDEFAULTSV) contains system-wide security defaults, but it does not track individual user password activity.
Option D (DBC.ACCESSLOGV) logs access control events, like who accessed which database objects, but it doesn't track password changes either.

Therefore, DBC.USERSV is the appropriate view to use for this task.

QUESTION: 12

A client has a healthy system but often sees delays in some queries because of workload concurrency limits. These limits have been carefully chosen, so the client needs a solution that will not modify them.
What should the Administrator use to assist this client?

Use a system throttle.
Use Query Group Viewpoint gortjet to change the throttle limit temporally.
Use Flex Throttle option.
Use Query Monitor Viewpoint portlet to change query workloads.

Answer(s): C

Explanation:

The Flex Throttle option allows the system to temporarily adjust workload concurrency limits based on system conditions. This provides more flexibility when handling spikes in query concurrency, without permanently modifying the established workload limits. Flex Throttle is ideal for handling temporary peaks in activity, helping to smooth out delays while keeping the core concurrency limits intact.
Option A (Use a system throttle) would enforce strict concurrency limits but doesn't provide the flexibility needed in this scenario, where the client is trying to avoid modifying existing limits. Option B (Use Query Group Viewpoint portlet to change the throttle limit temporarily) suggests manually adjusting the throttle limit, which is not desirable in this case as the limits have been carefully chosen.
Option D (Use Query Monitor Viewpoint portlet to change query workloads) would involve changing the way queries are handled or prioritized but does not address the need to keep concurrency limits unchanged while still dealing with temporary delays.
Thus, Flex Throttle (Option C) provides the best solution to assist the client without altering the concurrency limits permanently.

QUESTION: 13

Given a user creation request on a 10-AMP system:
CREATE USER hr_user AS PERM = 100e9 SKEW = 10 PERCENT, SPOOL = 100e9 SKEW = 20 PERCENT;
How does the SKEW factor affect the user's Perm space, assuming the total space consumed is under the specified perm space limit?

The per AMP limit of any AMP can reach 20 GB.
The per AMP limit of 100 GB can be breached up to 10 percent.
The per AMP limit of 10 GB can be breached to any percent.
The per AMP limit of any AMP can reach 11 GET

Answer(s): D

Explanation:

In the given CREATE USER statement, the SKEW = 10 PERCENT parameter applies to Perm space and allows some AMPs (Access Module Processors) to use up to 10% more space than the average allocation across the AMPs.
The user is allocated 100 GB of Perm space across a 10-AMP system, meaning the average space per AMP is 10 GB.
With a 10% skew allowed, this means that an AMP can use up to 10% more than the average allocation, which is 10 GB + 1 GB = 11 GB.

QUESTION: 14

An Administrator has been tasked with analyzing previous growth and usage patterns by utilities such as Multiload and FastLoad. The aim is to project the likely resource requirements of the existing loads in the next three to six months.
In the last month, the Administrator team have started using AccountString expansion on all user accounts and have started maintenance jobs to housekeep system data older than seven years. Two years ago, the following command was issued on the system:
BEGIN QUERY LOGGING WITH ALL ON ALL;
No other logging commands have been issued.
Which view contains the utility usage data for the prior months?

AMPUsageV
LogOnOffV
QryLogUtilityV
QryLogV

Answer(s): C

Explanation:

QryLogUtilityV is a specific DBQL (Database Query Logging) view that provides information about utility usage (such as Multiload and FastLoad) on the system. Since the BEGIN QUERY LOGGING WITH ALL ON ALL command was issued two years ago, the DBQL (Database Query Logging) has been tracking various events, including utility usage, which is stored in QryLogUtilityV. Option A (AMPUsageV) contains AMP (Access Module Processor) level statistics and usage data but not detailed information about utility jobs.
Option B (LogOnOffV) tracks user logon and logoff activities but does not provide information about utility usage.
Option D (QryLogV) logs general query execution data but is not specifically focused on utility usage.

QUESTION: 15

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?

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

Answer(s): D

Explanation:

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.
