• Question 205:

  An LTM Specialist has configured a virtual server for www.example.com, load balancing connections to a pool of application servers that provide a shopping cart application. Cookie persistence is enabled on the virtual server. Users are able

  to connect to the application, but the user's shopping cart fails to update. A traffic capture shows the following:

  Request:

  GET /cart/updatecart.php HTTP/1.1

  Host: www.example.com

What should the LTM Specialist do to resolve the problem?

  A. Use an iRule to rewrite the cartID cookie domain.
  B. Create a universal persistence profile on the cartID cookie.
  C. Enable source address persistence as a fallback persistence method.
  D. Create a cookie persistence profile with "match across services" enabled.
  A. Use an iRule to rewrite the cartID cookie domain.

• Question 206:

  What does the following iRule do? when CLIENT_ACCEPTED {

  if { [matchclass [IP::client_addr] equals WebClient1-Whitelist1] }{

  #log local0. "Valid client IP: [IP::client_addr] - forwarding traffic"

  #Pool WebClient1

  } else {

  log local0. "Invalid client IP: [IP::client_addr] - discarding"

  discard

  }

  }

  A. The iRule compares a client IP to a list. If the client IP is on the list, discard and log the discard.
  B. The iRule compares a client IP to a list. If the client IP is NOT on the list, discard and log the discard.
  C. The iRule compares a client IP to a list. If the client IP is on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.
  D. The iRule compares a client IP to a list. If the client IP is NOT on the list, the client is sent to Pool WebClient1. Otherwise, discard and log the discard.
  B. The iRule compares a client IP to a list. If the client IP is NOT on the list, discard and log the discard.

• Question 207:

  Refer to the exhibit.

  

  An LTM Specialist is troubleshooting an issue with SSL and is receiving the error shown when connecting to the virtual server. When connecting directly to the pool member, clients do NOT receive this message, and the application functions correctly. The LTM Specialist exports the appropriate certificate and key from the pool member and imports them into the LTM device. The LTM Specialist then creates the Client SSL profile and associates it with the virtual server.

  What is the issue?

  A. The SSL certificate and key have expired.
  B. The SSL certificate and key do NOT match.
  C. The client CANNOT verify the certification path.
  D. The common name on the SSL certificate does NOT match the hostname of the site.
  C. The client CANNOT verify the certification path.

• Question 208:

  Refer to the exhibit.

  B. 2

  C. 3

  D. 4

  E. 5

• Question 210:

  What is a benefit provided by F5 Enterprise Manager?

  A. Enterprise Manager allows administrators to analyze traffic flow and create custom application IPS signatures.
  B. Enterprise Manager allows administrators to establish baseline application usage and generate an alert if an administratively set threshold for the application is exceeded.
  C. Enterprise Manager allows administrators to identify application vulnerabilities. Virtual patches are then automatically generated and applied to remediate the detected application vulnerability.
  D. Enterprise Manager allows administrators to monitor all application traffic. Configuration optimization suggestions based on the observed traffic patterns are then generated for the administrator to review and apply.
  B. Enterprise Manager allows administrators to establish baseline application usage and generate an alert if an administratively set threshold for the application is exceeded.
