• Question 132:

  An LTM device pair is configured for failover and connection mirroring. The LTM devices are configured with virtual servers for HTTP, HTTPS with SSL offload, and SSH. An event occurs that causes a failover. HTTP and SSH sessions active at the time of failover remain active, but HTTPS sessions are dropped.

  What is the root cause of this problem?

  A. The SSL certificates on the LTM devices do NOT match.
  B. Connection mirroring is incompatible with clientssl profiles.
  C. SNAT automap was NOT enabled for the HTTPS virtual servers.
  D. Connection mirroring was NOT enabled for the HTTPS virtual servers.
  B. Connection mirroring is incompatible with clientssl profiles.

• Question 133:

  Refer to the exhibit.

  

  

  An LTM Specialist has configured a virtual server to distribute connections to a pool of application servers and to offload SSL processing. The application fails to work as expected when connecting to the virtual server. It does work when clients connect directly to the application. Two packet captures were taken at the application server.

  What is the root cause of the problem?

  A. The application servers are NOT listening on port 80.
  B. The LTM device is sending non-SSL traffic to an SSL port.
  C. The virtual server does NOT have a clientSSL profile assigned.
  D. The SSL handshake between the LTM device and the server is failing.
  B. The LTM device is sending non-SSL traffic to an SSL port.

• Question 134:

  Refer to the exhibit.

  

  An LTM Specialist is performing an HTTP trace on the client side of the LTM device and notices there are many undesired headers being sent by the server in the response. The LTM Specialist wants to remove all response headers except "Set-Cookie" and "Location."

  How should the LTM Specialist modify the HTTP profile to remove undesired headers from the HTTP response?

  A. Enter the desired header names in the 'Request Header Insert' field.
  B. Enter the undesired header names in the 'Request Header Erase' field.
  C. Enter the undesired header names in the 'Response Header Erase' field.
  D. Enter the desired header names in the 'Response Headers Allowed' field.
  D. Enter the desired header names in the 'Response Headers Allowed' field.

• Question 135:

  Refer to the exhibit.

  

  The three VLANS shown provide connectivity to backend servers. The backend servers are being moved to unmanaged switches and require separate interfaces. How should the F5 device interfaces be configured?

  A. Create a Trunk interface and combined interface 1.1.1.2 and 1.3.
  B. Create a Trunk interface and select VLAN,,A, VLAN_B. and VLAN_C.
  C. Create VLAN named VLAN_A enter 100 under Tag and moveinterface 1.1 to tagged Create VLAN_B enter 200 and move interface 1.2 to tagged Create VLAN_C Center 300 and move interface 1.3 to tagged.
  D. Create VLAN_A move interface 1.1 to untagged. Create VLAN_B move interface 1.2 to untagged. Create VLAN_C move interface 1.3 to untagged.
  D. Create VLAN_A move interface 1.1 to untagged. Create VLAN_B move interface 1.2 to untagged. Create VLAN_C move interface 1.3 to untagged.
