Which of the following authentication methods is supported by IBM Cognos Analytics for user access?
Single Sign-On (SSO)
Role-based authentication
oken-based authentication wer: A
anation: IBM Cognos Analytics supports Single Sign-On (SSO) as an entication method for user access. SSO allows users to log in to the sy and access multiple applications or systems without the need to provi entials again. It provides a seamless and secure authentication experie sers.
on B is incorrect because role-based authentication is not an authentic od but rather a mechanism for granting different permissions and acce
based on user roles.
on C is incorrect because LDAP (Lightweight Directory Access Proto entication is a common method for authenticating users against a direc ce, such as Active Directory, but it is not the only authentication meth orted by IBM Cognos Analytics.
on D is incorrect because token-based authentication typically involve f access tokens or bearer tokens for authentication and authorization,

An administrator needs to address an environment that is not running optimally and conduct an architecture review.
Which performance attributes should be considered?
capacity, scalability, availability
gateways, application servers, Content Manager
IBM Cognos implementation, capacity, infrastructure
anation: When conducting an architecture review to address performa s in an IBM Cognos Analytics environment, the administrator should ider the IBM Cognos implementation itself, the capacity of the structure, and the overall infrastructure setup. These factors play a cru n optimizing the performance of the system.
on A is incorrect because while capacity, scalability, and availability a rtant performance attributes, they do not specifically address the IBM nos implementation and infrastructure.
on B is incorrect because gateways, application servers, and Content ager are components of the IBM Cognos Analytics architecture, but th ot encompass all the performance attributes that need to be considered on D is incorrect because while infrastructure, gateways, application ers, and scalability are relevant to performance, they do not cover the e
of performance attributes that should be assessed during an architect w.

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?
If a service is disabled in IBM Cognos Configuration, it is listed in the
Scorecard pane.
The status that is displayed for each entry reflects the lowest status for all child entries.
A status of Available is displayed when at least 80% of the child entries have a status of Available.
wer: B
anation: In the Scorecard pane, the status displayed for each entry refl owest status among all child entries. This means that if any child entry wer status, such as Unavailable, the overall status for the parent entry w e Unavailable. This provides a consolidated view of the system statu
administrators quickly identify any potential issues or areas that requ tion.
ch of the following techniques can be used to enhance the performanc report execution in IBM Cognos Analytics?
mplementing data caching
creasing the number of user connections nabling verbose logging
educing the number of report parameters
A status of Unavailable is displayed when at least 80% of the child entries have a status of Unavailable.

Answer: A
Explanation: One technique to enhance the performance of report execution in IBM Cognos Analytics is implementing data caching. Data caching involves storing the results of frequently executed queries in memory or disk storage, allowing subsequent executions of the same query to retrieve the data from the
cache rather than querying the data source again. This can significantly improve the response time of reports and reduce the load on the data source.
on D is incorrect because reducing the number of report parameters m the flexibility and functionality of the reports, but it may not have a ficant impact on the performance of report execution. Other optimizat niques, such as data filtering and query optimization, are more effectiv oving performance.
ch of the following components are part of the IBM Cognos Analytics er environment?
eport Studio, Query Studio, Analysis Studio ateway, Content Manager, Application Server ramework Manager, Transformer, Event Studio ata Source, ETL Tool, Data Warehouse
Option B is incorrect because increasing the number of user connections may strain the system resources and potentially degrade performance, especially if the system is not appropriately scaled or optimized to handle the increased load. Option C is incorrect because enabling verbose logging, which generates detailed log files, can consume additional system resources and may not directly impact the performance of report execution.

Answer: B
Explanation: The IBM Cognos Analytics server environment consists of several components, including the Gateway, Content Manager, and Application Server. Option A is incorrect because Report Studio, Query Studio, and Analysis Studio are client tools used for report authoring and analysis, not server components.
Option C is incorrect because Framework Manager, Transformer, and Event Studio are also client tools used for modeling, transforming data, and creating event-driven reports, respectively.
Option D is incorrect because Data Source, ETL Tool, and Data Warehouse are not specific to the IBM Cognos Analytics server environment but rather represent general data management and integration components.
ch of the following statements about report execution in IBM Cognos ytics is true?
eport execution can only be triggered manually by users. eport execution is independent of the underlying data sources. eport execution can be scheduled and automated.
eport execution requires the administrator's approval. wer: C
anation: In IBM Cognos Analytics, report execution can be scheduled mated. This means that reports can be set to run at specific times or vals without manual intervention. This scheduling and automation feat ws for regular and timely generation of reports, reducing the need for ual execution.
on A is incorrect because report execution can be triggered both manu

by users and automatically through scheduled jobs.
Option B is incorrect because report execution is dependent on the underlying data sources. The data must be available and up-to-date for the reports to execute successfully.
Option D is incorrect because the administrator's approval is not required for report execution. The administrator's role is primarily focused on system administration and monitoring rather than individual report execution.
Which of the following is NOT a recommended practice for managing the IBM Cognos Analytics server environment?
pplying software updates and patches in a timely manner estricting access to the system only to administrators acking up system configurations and content regularly
wer: C
anation: Restricting access to the IBM Cognos Analytics system only nistrators is not a recommended practice for managing the server onment. While administrators require privileged access for system nistration tasks, it is important to provide appropriate access to other
such as report authors, analysts, and business users, based on their r esponsibilities.
on A is a recommended practice because monitoring system performa esource usage helps identify and resolve any performance issues or enecks.
on B is a recommended practice because applying software updates an hes in a timely manner ensures that the system remains secure and up t
ith thelatest fixes and enhancements.
