Question 1

A new VLAN vlan301 has been configured on a highly available LTM device in partition ApplicationA. A new

directly connected backend server has been placed on vlan301. However, there are connectivity issues pinging

the default gateway. The VLAN self IPs configured on the LTM devices are 192.168.0.251 and 192.168.0.252

with floating IP 192.168.0.253. The LTM Specialist needs to perform a packet capture to assist with

troubleshooting the connectivity.

Which command should the LTM Specialist execute on the LTM device command line interface to capture the

attempted pings to the LTM device default gateway on VLAN vlan301?

Options :

A :

tcpdump -ni /ApplicationA/vlan301 'host 192.168.0.253'

B : tcpdump -ni vlan301 'host 192.168.0.253'

C :

tcpdump -ni /ApplicationA/vlan301 'host 192.168.0.251 or host 192.168.0.252'

D :

tcpdump -ni vlan301 'host 192.168.0.251 or host 192.168.0.252'

Answer: A

Question 2

An LTM device is load balancing SIP traffic. An LTM Specialist notices that sometimes the SIP request is being

load balanced to the same server as the initial connection.

Which setting in the UDP profile will make the LTM device more evenly distribute the SIP traffic?

Options :

A : Enable Datagram LB

B : Disable Datagram LB

C : Set Timeout to Indefinite

D :

Set Timeout to Immediate

Answer: A

Question 3

An LTM Specialist configures the following iRule on an LTM device:

when HTTP_REQUEST {

if {[string tolower [HTTP::uri]] contains "/URI1/" } {

pool Pool1

}

elseif {[string tolower [HTTP::uri]] contains "/URI2/" } {

pool Pool2

}

elseif {[string tolower [HTTP::uri]] contains "/URI3/" } {

pool Pool3

}

else { pool Pool4}

}

Given the following request: http://www.example.comURI1/index.html?fu=bar&pass=1234

Which pool will be selected by the iRule?

Options :

A : Pool1

B : Pool2

C : Pool3

D : Pool4

Answer: D

Question 4

-- Exhibit –

-- Exhibit --

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?

Options :

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.

Answer: D

Question 5

-- Exhibit –

-- Exhibit --

Refer to the exhibits.

After upgrading LTM from v10 to v11, users are unable to connect to an application. The virtual server is using

a client SSL profile for re-terminating SSL for payload inspection, but a server SSL profile is being used to reencrypt the request.

A client side ssldump did NOT show any differences between the traffic going directly to the server and the

traffic being processed by the LTM device. However, packet capture was done on the server, and differences

were noted.

Which modification will allow the LTM device to process the traffic correctly?

Options :

A :

Enable Strict Resume.

B :

Change Secure Renegotiation to "Request."

C :

Enable ProxySSL option in the server SSL profile.

D :

Change to different ciphers on the server SSL profile.
