• Question 42:

  The computer where a federated node was running had a failure and cannot be recovered. A system administrator wants to recreate the node with the same configurations in another computer. Which steps should the administrator execute in order to recover the damaged node?

  A. Configure the new computer with a different hostname.Create a custom profile with the same name.Federate to the cell using the command addNode with the default options.
  B. Configure the new computer with a different hostname.Create a custom profile with a different name.Federate to the cell using the command addNote with the option 璦sExistingNode.
  C. Configure the new computer with the same hostname.Create a custom profile with the same name.Federate to the cell using the command addNote with the option 璦sExistingNode.
  D. Configure the new computer with the same hostname.Create a custom profile with the same name.Federate to the cell using the command addNote with the options 璱ncludeapps.
  C. Configure the new computer with the same hostname.Create a custom profile with the same name.Federate to the cell using the command addNote with the option 璦sExistingNode.

  ---

  You can use the -asExistingNode option of the addNode command to recover and move nodes of a deployment manager. Using the -asExistingNode option, federate a new custom node to a deployment manager as an existing node. During

  federation, the product uses information in the deployment manager master configuration to transform the custom node into the existing node.

• Question 43:

  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?

  A. Configure the SIP digest authentication.
  B. Configure the SPNEGO Web or SPNEGO TAI.
  C. Enable Session Management Security Integration.
  D. Ensure Web Inbound security attribute propagation is enabled.
  B. Configure the SPNEGO Web or SPNEGO TAI.

  ---

  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.

• Question 44:

  A new cell contains a cluster with members defined in two managed nodes running on two different machines. The cell also contains two unmanaged nodes running on HTTP servers with HTTP plug-in. Session persistence has been enabled. Which additional component(s) can the system administrator configure to make this environment highly available?

  A. Enable administrative security.
  B. Configure a DMZ secure proxy.
  C. Configure High Performance Extensible Logging.
  D. Configure primary and backup load balancers for the HTTP servers.
  D. Configure primary and backup load balancers for the HTTP servers.

• Question 45:

  There are many applications deployed in a large WebSphere Application Server cluster. A system administrator is required to give Configurator role access to a developer for a single application deployed in that cluster. How should the administrator meet this requirement and restrict Configurator role access for a single application?

  A. Create a J2C authentication alias for that developer.
  B. Create an Administrative user role and provide Configurator access to the developer.
  C. Create an Administrative group role and provide Configurator access to the developer.
  D. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configurator access to the developer.
  D. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configurator access to the developer.

  Fine-grained administrative security

  In releases prior to WebSphere?Application Server version 6.1, users granted administrative roles could administer all of the resources under the cell. WebSphere Application Server is now more fine-grained, meaning that access can be

  granted to each user per resource.

  For example, users can be granted configurator access to a specific instance of a resource only (an application, an application server or a node).

  To achieve this instance-based security or fine-grained security, resources that require the same privileges are placed in a group called the administrative authorization group or authorization group. Users can be granted access to the

  authorization group by assigning to them the required administrative role.

• Question 47:

  A system administrator has added a server cluster as a member of a service integration bus (SIB). The administrator needs to configure one messaging engine for each server in this cluster and to have a failover location for each messaging engine.

  What should the administrator do to achieve the required design?

  A. Configure a new messaging engine in each server to support failover.
  B. Configure the data store for each messaging engine for each server in the cluster.
  C. Select scalability with high availability as the messaging engine policy.
  D. Create a core group policy to restrict each messaging engine to a particular server.
  C. Select scalability with high availability as the messaging engine policy.

  ---

  The scalability with high availability configuration ensures that there is a messaging engine for each server in a cluster, and that each messaging engine has a failover location. http://www-01.ibm.com/support/knowledgecenter/SSCKBL_8.5.5/com.ibm.websphere.nd.doc/ae/cjt10 04_.html (second paragraph)

• Question 48:

  Setting up Liberty server clusters

  A Liberty can be configured into a server cluster for application high availability and scale. The collectiveController-1.0 feature and its capabilities are available only in multiple-server products such as WebSphere?Application Server Liberty

  Network Deployment and WebSphere Application Server Liberty for z/OS. The feature is not available in single- server products such as WebSphere Application Server Liberty, WebSphere Application Server Liberty - Express, or WebSphere

  Application Server Liberty Core. If you have a multiple-server product installation, you can use its collectiveController-1.0 feature to work with collective members from single-server products.
