IBM IBM Certifications C9510-418 Questions & Answers

• Question 111:

  Which is true about software repositories for IBM Installation Manager?

  A. Repositories must be local.

  B. Repositories must be online.

  C. Repositories can be either local or online.

  D. Repositories are only in the media package.

  Correct Answer: C

  IBM Installation Manager is a single installation program that can use remote or local software repositories to install, modify, or update certain IBM products. It determines and shows available packages, checks prerequisites and interdependencies, and installs or modifies the selected packages. You also use IBM Installation Manager to uninstall the packages that it installed.

• Question 112:

  What data source property can an administrator configure to minimize the chances of encountering StaleConnectionExceptions?

  A. Minimum connections = 0

  B. Reap Timeout < Unused Timeout

  C. Purge Policy = FailingConnectionOnly

  D. Unused Timeout > Half firewall timeout

  Correct Answer: A

  The configuration options below help minimize the chances of encountering StaleConnectionExceptions by helping to ensure that your WebSphere Application Server maintains control of database connections, specifically, the only one closing them, rather than other components in your network: The datasource MIN connections should be set to 0. By setting a MIN > 0, you are telling the application server that this number of connections will be valid for the life of the application server JVM. Unless you can guarantee the MIN number of connections will never be timed out or dropped, setting a MIN will cause

  a StaleConnectionException when the connection becomes invalid.

• Question 113:

  Which of the following is required for Secure Sockets Layer (SSL) enablement within an HTTP server?

  A. A JDK

  B. A valid, issued certificate

  C. IPv6 (Internet Protocol Version 6)

  D. Updating the https.conf file and not the httpd.conf file

  Correct Answer: B

  The iKeyman GUI, which is included within the IBM HTTP Server distribution, can be used to create a key database file (for example: key.kdb) needed to store personal server certificates required by the client browser during an SSL handshake.

  Incorrect Answers:

  D: Enable SSL directives within the IBM HTTP Server's configuration file (httpd.conf)

• Question 114:

  Which statement describes the functionality of web containers?

  A. Web containers forward EJB requests to the EJB container.

  B. Web containers process JSPs, servlets, and various server-side objects.

  C. Servlets requests are forwarded from an EJB container to a web container.

  D. Each application server can contain multiple web containers, depending upon the number of JSPs and servlets.

  Correct Answer: B

  The runtime environment for Web components is called the Web container. It processes servlets, JSP files, and other types of server-side components.

• Question 115:

  An administrator wants to verify an IBM WebSphere Application Server installation by examining the installation's directory structure. In this example, indicates the installation's root directory.

  What is one directory tree structure that indicates a successful installation of the product files?

  A. /web

  B. /bin

  C. /profiles

  D. /installableApps

  Correct Answer: C

  Application Server Version 8.5.5 for Network Deployment: /QIBM/UserData/WebSphere/AppServer/V85/ND/profiles/wp_profile/PortalServer

  Reference: https://www.ibm.com/support/knowledgecenter/en/SSYJ99_8.5.0/reference/wpsdirstr.html

• Question 116:

  Which type of profile provides management capabilities for multiple stand-alone application servers?

  A. Custom

  B. Secure Proxy

  C. Administrative agent

  D. Deployment manager

  Correct Answer: C

  You can use the following different configurations of the application server to combine the plug-in configuration files of multiple application server profiles into a single output file:

  * Using multiple stand-alone base application server profiles with an administrative agent using the job

  manager. The job manager function is a part of WebSphere Application Server Network Deployment.

  However, you can use the job manager function with stand-alone, base application server profiles. Use

  this topic to complete this configuration.

  Etc.

• Question 117:

  Which two methods are used for communicating session linkages between the client and the server? (Choose two.)

  A. Cookies

  B. LTPA Token

  C. Rest Services

  D. URL Rewriting

  E. HTTP Response codes

  Correct Answer: CE

  Representational State Transfer (REST) is a lightweight framework for designing applications that use

  HTTP to make calls. REST uses HTTP to perform the Create, Read, Update, and Delete (CRUD)

  operations between client and server.

  Applications interact with the services by using HTTP, POST, PUT, GET, and DELETE operations.

• Question 118:

  What is a benefit of using the IBM Extended Cache Monitor?

  A. It invalidates cacheids.

  B. It displays the contents of the cache instances.

  C. It displays the contents of object cache instances.

  D. It displays the dependency ids of the cache instances.

  Correct Answer: C

  The IBM Extended Cache Monitor for IBM WebSphere Application Server provides you with two functions that are not available with the cache monitor that is supplied with WebSphere Application Server. These two functions enable you to: display the contents of object cache instances display the Dynamic Cache mbean statistics for cache instances

• Question 119:

  Through what protocol can a Java client directly access EJBs running on an application server?

  A. JDBC

  B. RMI/IIOP

  C. SOAP/JMS

  D. SOAP/HTTP

  Correct Answer: D

  Provided that it uses the correct protocols (SOAP, HTTP, WSDL), any web service client can access a stateless session bean, whether or not the client is written in the Java programming language. The client doesn't even "know" what technology implements the service: stateless session bean, JAX-WS, or some other technology. In addition, enterprise beans and web components can be clients of web services. This flexibility enables you to integrate Java EE applications with web services.

• Question 120:

  When setting up high availability settings for the web server, at what level should an administrator configure the custom properties?

  A. cell

  B. node

  C. server

  D. nodeagent

  Correct Answer: C
