IBM C2090-623 Exam Questions Instant Access

Question 1

An administrator is creating a datasource for an IBM Cognos PowerCube. On the datasource creation page, the 'Configure JDBC connection' check box is played out and cannot be selected.

What is the reason for this?

AThe IBM Cognos PowerCube is not optimized.

BThe execution mode for the dispatcher is not set to 64 bit.

CThe execution mode for the environment is not set to 64 bit.

DJDBC connection is not supported for IBM Cognos PowerCube.

Answer : B

Compatible query mode

To run reports that use the compatible query mode, you must use 32-bit data source client libraries and configure the report server to be 32-bit. The compatible query mode uses native client and ODBC connections to communicate with data sources.

If the data source is 64-bit, ensure that you use the 32-bit client libraries to connect to the data source to use the compatibility query mode.

Question 2

An administrator is evaluating system status using the Scorecard pane on the Status > System page in the IBM Cognos Administration console.

Which statement is true?

AIf a service is disabled in IBM Cognos Configuration, it is listed in the Scorecard pane.

BThe status that is displayed for each entry reflects the lowest status for all child entries.

CA status of Available is displayed when at least 80% of the child entries have a status of Available.

DA status of Unavailable is displayed when at least 80% of the child entries have a status of Unavailable.

Answer : B

The metric score for each entry is based on the performance of individual child entries. The status that is displayed for each entry is the lowest status of the child entries. For example, if all the metrics for a dispatcher are good, but one service on that dispatcher has a poor metric, the metric score shown for the dispatcher is poor.

Status is one of the following:

Question 3

Which attribute can an administrator enable to prevent malicious scripts from reading or manipulating the CAM passport cookie during a user's session with their Web browser?

Acc_session

BuserCapabilities

CSecure flag enabled?

DEnable CAF validation?

Answer : B

The userCapabilities cookie, with the Session temporary type, contains all capabilities and the signature for the current user.

Question 4

Which policy rule is defined by this statement?

''If a policy has not been explicitly defined for an IBM Cognos Analytics object, then the policy that is applied to its parent object will be used to evaluate if the object can be accessed.''

AAcquired policies

BGroup inheritance

CUnion of permissions

DTraversing to view child entries

Answer : D

Users must have at least traverse permissions for the parent entries of the entries they want to access. The parent entries include container objects such as folders, packages, groups, roles, and namespaces.

Question 5

An administrator sees that an environment has a long startup time and wants to remedy the issue.

Which solution should be used?

ASet load balancing to cluster compatible.

BCheck the Fast Startup option under IBM Cognos Configuration.

CIncrease the size of the JVM heap by selecting Large configuration.

DReduce the size of the Content Store through archiving and removal.

Answer : A

If your IBM Cognos servers operate within a load balancing infrastructure, you can turn off the weighted round robin format of load balancing for the dispatcher. Otherwise, load balancing may be duplicated by the cluster and by IBM Cognos software, which can degrade performance.

You can set the dispatcher property named loadBalancingMode either to weightedRoundRobin or clusterCompatible.

Question 6

To monitor performance, an administrator has set thresholds on a system metric and notices that over time, the metric score has changed from green, to yellow, to red, and then back to yellow.

Which system metric is the administrator monitoring?

ADispatcher: JVM: Current heap size

BContentManageService: Request: Number of failed requests

CReportService: Process: Number of processes high watermark

DBatchReportService: Request: Percentage of successful requests

Answer : B

Question 7

An administrator is configuring settings for the Cognos Analytics Mobile app.

Which settings can be managed?

ATo store the user credentials in the IBM Cognos Mobile app.

BThe maximum number of minutes to store cached credentials.

CAllow the user to create an image (screenshot) of the Active Report.

DThe maximum number of Active Reports to store locally on the mobile device.

Answer : B

Policy settings

These settings define how to deliver Cognos Analytics content to mobile applications.
