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 Specialist must perform a packet capture on a virtual server with an applied standard FastL4 profile.

The virtual server 10.0.0.1:443 resides on vlan301.

Which steps should the LTM Specialist take to capture the data payload successfully while ensuring no other

virtual servers are affected?

Options :

A :

The standard FastL4 profile should have PVA acceleration disabled. Then the packet capture tcpdump -ni

vlan301 should be executed on the command line interface.

B :

The packet capture tcpdump -ni vlan301 should be executed on the command line interface. There is no

need to change profiles or PVA acceleration.

C :

A new FastL4 profile should be created and applied to the virtual server with PVA acceleration disabled.

Then the packet capture tcpdump -ni vlan301 should be executed on the command line interface.

D :

The LTM device is under light load. The traffic should be mirrored to a dedicated sniffing device. On the

sniffing device, the packet capture tcpdump -ni vlan301 should be executed.

Answer: C

Question 3

An LTM HTTP pool has an associated monitor that sends a string equal to 'GET /test.html'.

Which two configurations could an LTM Specialist implement to allow server administrators to disable their

pool member servers without logging into the LTM device? (Choose two.)

Options :

A :

Set monitor to transparent and ask the server team to set string ‘TRANSPARENT’ in test.html.

B :

Set ‘receive string’ equal to 'SERVER UP and ask the server team to set string ‘SERVER DOWN’ in

test.html.

C :

Set ‘alias’ equal to 'SERVER DOWN’ and ask the server team to set string ‘SERVER DOWN’ in test.html.

D : Set ‘receive disable string’ equal to 'SERVER DOWN’ and ask the server team to set string ‘SERVER DOWN’ in test.html.

E :

Set ‘disable pool member’ equal to 'SERVER UP’ and ask the server team to set string ‘SERVER DOWN’

in test.html.

Answer: B,D

Question 4

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 5

A device on the network is configured with the same IP address as the management address of the active LTM

device, causing the management GUI to be inaccessible.

Which two methods should the LTM Specialist use to access the LTM device in order to change the

management IP address? (Choose two.)

Options :

A : Connect via ssh to the AOM IP address.

B :

Connect via ssh to the management address.

C :

Connect to the LTM device via serial connection.

D :

Connect a monitor and keyboard to the LTM device.

E :

Connect via ssh to the standby unit and connect via ssh across the serial link between the devices.
