WebSphere Application Server (WAS) is a web application server that runs on IBM's WebSphere platform. It is, more precisely, a software framework and middleware for hosting Java-based web applications. It is the centerpiece of IBM's WebSphere software suite.
Question 1: What does FFDC stand for?
(a) Failure First Data Capture
(b) First Failure Data Capture
(c) Fail Fail Data Capture
(d) Fault Failure Data Capture
Explanation: First Failure Data Capture (FFDC) is used in order to collect information on the events and conditions that lead to a failure so that they don't have to recreate it.
Question 2: JDBC is?
(d) Java Connector
Explanation: The JavaSoft specification for a standard application programming interface (API) that allows Java programmes to access database management systems is known as Java database connectivity (JDBC).
Question 3: Which component in a WebSphere cell design constitutes a single point of failure?
(a) EJB container
(b) Deployment manager
(c) Web container
(d) HTTP server
Explanation: The deployment manager is an administrative application that runs in a special application server that is generated when you install the WebSphere Application Server Network Deployment product or when you use the deployment manager profile template to establish a management profile.
Question 4: Which of the following statements concerning the FFDC feature is correct?
(a) FFDC logs are mainly intended for application development teams.
(b) The application server needs to be restarted after enabling FFDC.
(c) FFDC information is stored in an optimized relational database.
(d) FFDC does not affect the performance of the WebSphere application server.
Explanation: FFDC is the abbreviation for "First Failure Data Capture."
Question 5: Which of the following statements concerning WebSphere Application Server ND's Load Balancer Edge component is correct?
(a) Performance is reduced due to the routing algorithm.
(b) It provides session affinity.
(c) The load cannot be balanced by it on platform attributes or unique applications.
(d) It does not provide for site selection.
Explanation: Incoming requests are routed to the proper server based on a set of criteria, which may involve load balancing requests over multiple servers.
Question 6: Which changes to Web module parameters would result in a faster response time for Web clients?
(a) By disabling load on startup
(b) By setting the distributable flag
(c) By setting the reload interval to 20 seconds or less
(d) By enabling the pre-compile JSP option
Explanation: Enabling pre-compile JSP option in Web module parameters would result in a faster response time for Web clients.
Question 7: Which configuration choice is the easiest to maintain and operate if a Web server is placed in the intranet, behind the DMZ (Demilitarized Zone)?
(a) The web server in an unmanaged node
(b) The web server in a stand-alone profile
(c) The web server in a managed node
(d) None of the above
Explanation: WebSphere Application Server, Java Message Service (JMS) servers, web servers, and generic servers can all be found on a managed node in a cell.
Question 8: An administrator would like to verify that HTML resources are isolated amongst Web modules running on a server for security reasons. Which of the administrator's settings should be changed?
(a) Class loader configuration
(b) HTTPS port configuration
(c) Admin console configuration
(d) Virtual host configuration
Explanation: For configuration reasons, a virtual host is a configuration entity that allows WebSphere Application Server to handle numerous host machines or port numbers as a single logical host (virtual host). Multiple aliases can be assigned to each virtual host.
Question 9: Which of the following are the two most popular SSL encryption techniques?
(a) 40 and 164
(b) 128 and 256
(c) 40 and 128
(d) None of the above
Explanation: 40 and 128 are the two most popular SSL encryption techniques. SSL (Secure Sockets Layer) is an Internet security protocol that uses encryption.
Question 10: Which servlet is appropriate for validating system configuration after installation and application server profile creation?
(c) Hit Count
(d) None of these
Explanation: Snoop servlet is appropriate for validating system configuration after installation and application server profile creation.
