Question No. 1

A system administrator needs to deploy a new enterprise application which requires that application security be enabled, but, the existing applications in the cell cannot be executed with application security enabled. The cell has the global security and Java 2 security disabled.

How can the administrator handle this requirement?

AEnable Java 2 security for the cell.Create a security domain with application security enabled.Associate the security domain to the new application.

BEnable Java 2 security for the cell.Create a security domain with application security enabled.Associate the security domain to a new cluster to be used to deploy the new application.

CEnable administrative security for the cell.Create a security domain with application security enabled.Associate the security domain at the application level for the new application.

DEnable administrative security for the cell.Create a security domain with application security enabled.Associate the security domain to the new cluster where the new application is deployed.

Show Answer

Correct Answer: C

When Java 2 security is enabled for a WebSphere Application Server, all the applications that run on WebSphere Application Server undergo a security check before accessing system resources. An application might need a was.policy file if it accesses resources that require more permissions than those granted in the default app.policy file

Question No. 2

A system administrator has deployed web applications to a clustered environment where database session persistence is configured. The administrator needs to improve the response time and the throughput.

How can the system administrator do this?

ADisable server affinity.

BConfigure dynamic caching.

CConfigure a load balancer to spread work between existing web servers.

DTune the database session persistence to optimize for failover.

Show Answer

Correct Answer: B

The dynamic cache service improves performance by caching the output of servlets, commands, and JavaServer Pages (JSP) files. WebSphere Application Server consolidates several caching activities, including servlets, web services, and WebSphere commands, into one service called the dynamic cache. These caching activities work together to improve application performance and share many configuration parameters that are set in an application server's dynamic cache service.

Question No. 3

After collecting diagnostic trace from a server running under a cell, a system administrator noticed that the trace files contained sensitive information.

To avoid this issue in the future, what can the administrator do?

AConfigure entries in the ras.rawtracelist.properties.

BConfigure suppressSensitiveTrace in the bootstrap.properties file.

CClear the ''Disable logging and tracing of potentially sensitive data'' checkbox.

DAdd the entry com.ibm.websphere.logging.RawTraceList=off to the end of the trace string.

Show Answer

Correct Answer: C

You can either enable or disable the sensitive log and trace guard to help control whether loggers write sensitive information in your log and trace files.

Use the administrative console to enable or disable the sensitive log and trace guard.

Question No. 4

A newly deployed application has authorization errors when invoking EJB methods from a servlet. An additional review indicates that users are authenticated, but do not have the correct authorization.

How can a system administrator fix the issue ensuring only authorized access?

AUsing the Integrated Solutions Console (ISC), map all security roles to the special subject Everyone.

BUsing the Integrated Solutions Console (ISC), map the security roles that are still not mapped to groups in the correct user registry.

CEdit the application using an assembly tool to add a security constraint for the servlet and reinstall the application.

DEdit the application using an assembly tool to remove the security constraint defined for the servlet and reinstall the application.

Show Answer

Correct Answer: B

Question No. 5

A web application has a configured session timeout of eight hours and a default LTPA token timeout of two hours. After every two hours, the users have to log in again from their HTTP browser. The system administrator is required to make configuration changed so users only have to log in once, while keeping the above mentioned timeouts the same. The authentication mechanism available is Kerberos.

How should the administrator do this?

AConfigure the SIP digest authentication.

BConfigure the SPNEGO Web or SPNEGO TAI.

CEnable Session Management Security Integration.

DEnsure Web Inbound security attribute propagation is enabled.

Show Answer

Correct Answer: B

In WebSphere Application Server Version 6.1, a trust association interceptor (TAI) that uses the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) to securely negotiate and authenticate HTTP requests for secured resources was introduced. This function was deprecated In WebSphere Application Server 7.0. SPNEGO web authentication has taken its place to provide dynamic reload of the SPNEGO filters and to enable fallback to the application login method.
