IBM C9510-418 Online Questions & Answers

• Question 31:

  An administrator created a large cell which consists of 20 clusters with 10 cluster members in each cluster spanned across multiple nodes. During high business load on the cell, the administrator observed performance degradation. What action(s) can an administrator take to resolve performance degradation?

  A. Add more nodes on the existing computers in the cell.
  B. Split the large cell into two smaller calls and bridge them.
  C. Select multiple core group coordinators, and set core group wire transfer protocol to the latest available.
  D. Split the default core group into multiple core groups, and follow core group splitting and bridging rules as necessary.
  A. Add more nodes on the existing computers in the cell.

• Question 32:

  How can an administrator reduce overhead when utilizing monitored directories?

  A. Increase the polling interval so that the process runs less often.
  B. Decrease the amount of time that the monitored directory is accessible by users.
  C. Decrease the size of the monitored directory so that larger files will not be able to be stored in it.
  D. Configure the monitored directory settings to not automatically synchronize the application once it is installed.
  A. Increase the polling interval so that the process runs less often.

  ---

  To change the standard polling interval setting, specify a number of seconds in the Polling interval field. Figure: Configuring the monitored directory Reference: Application Server V8.5, July 2013, page 852

  

• Question 33:

  When building a partial application for IBM WebSphere Application Server, how should the files be packaged for deployment?

  A. The files should be placed in the same directory structure as they are in the .ear file and zipped.
  B. The files should be placed in the same flat folder, and the properties file should map the files to their intended destinations.
  C. The files should be placed in the same flat folder, named to match the directory structure of the deployed application, and zipped.
  D. The files can be placed in any directory structure the administrator decides, and then, manually replaces on the WebSphere Application Server file system.
  A. The files should be placed in the same directory structure as they are in the .ear file and zipped.

• Question 34:

  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
  D. SOAP/HTTP

  ---

  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 35:

  Which of the following is true about certificate expiration monitoring?

  A. Must be run manually.
  B. Must be run on the deployment manager.
  C. Deletes the certificates after they are expired, but does not replace them.
  D. Can replace expired certificates or certificates in the expiration threshold with a new certificate
  D. Can replace expired certificates or certificates in the expiration threshold with a new certificate

  ---

  Certificate monitor configuration settings can be configured on the administrative console by selecting Security > SSL certificate and key management > Manage certificate expiration. . On the Manage certificate expiration panel, you can

  perform the following functions.

  Set the expiration threshold in the box labeled Expiration replacement threshold. The expiration replacement threshold is the number of days before a certificate expiration that a certificate can be replaced and has a default value of 60 days.

  Delete the certificates after they are replaced by selecting the Delete expiring certificates and signers after replacement box. This box is selected by default.

  Etc.

• Question 36:

  What is the main difference between interim fixes and product fix packs as they relate to IBM WebSphere Application Server?

  A. Interim fixes typically contain new features or functionality ahead of future product fix packs.
  B. Product fix packs are a combination of interim fixes and internal fixes to make patching easier.
  C. Product fix packs are generally reserved for new features or functionality whereas interim fixes are provided only to fix known issues.
  D. Product fix packs bring WebSphere Application Server to a new product level whereas interim fixes provide corrective service for specific known problems.
  D. Product fix packs bring WebSphere Application Server to a new product level whereas interim fixes provide corrective service for specific known problems.

  ---

  Product fix packs contain bundled service to bring WebSphere Application Server up to a new product level. Interim fixes provide corrective service for specific known problems.

• Question 37:

  An administrator notices a sudden increase in the user load that causes resource contention on the database server. What preventive measure can the administrator take to avoid database outage?

  A. Enable surge protection.
  B. Configure Stuck connection.
  C. Reduce connection pool size.
  D. Reduce WebContainer Thread pool size.
  C. Reduce connection pool size.

  ---

  Maximum Connection Pool Size

  When determining the maximum size of the database connection pool, consider the following issues:

  The total number of connections that the WebSphere Commerce cluster can open to the database should not overwhelm your database.

• Question 38:

  What must be done to delete one or more files from an application when using a partial application update?

  A. Manually delete the files from the file system (on all nodes if clustered).
  B. Supply the paths to the files that should be deleted in the administrative console.
  C. Include a META-INF/ibm-partialapp-delete.props in the partial application update file.
  D. Select the files that need to be deleted in the file selector section of the form for the partial application update.
  C. Include a META-INF/ibm-partialapp-delete.props in the partial application update file.

  ---

  If you want to delete application files when you deploy a partial application update, you must first supply a special metadata file called META-INF/ibm-partialapp-delete.props in the partial application compressed file before you continue with

  the following procedure.

  Etc.

• Question 39:

  An administrator notices performance degradation after a new deployment of an application. After investigation, increased CPU usage is observed due to frequent GC cycles. However, there is no significant growth in the heap memory. How can the resource consumption issue be resolved?

  A. Increase max heap.
  B. Increase perm space.
  C. Increase nursery size.
  D. Change the GC policy.
  D. Change the GC policy.

• Question 40:

  Which of the following can be queried to get PMI data?

  A. Server Cell
  B. JMX Connectors
  C. MBean ObjectNames
