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?

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

-- Exhibit –

-- Exhibit --

Refer to the exhibit.

A client attempts to connect from a Google Chrome browser to a virtual server on a BIG-IP LTM. The virtual

server is SSL Offloaded. When the client connects, the client receives an SSL error. The client receives the

same errors when trying Mozilla Firefox and Internet Explorer browsers.

The LTM Specialist does an ssldump on the virtual server and receives the results as per the exhibit.

How should this be resolved?

A : Set the virtual server to listen on port 443 (HTTPS).

B : Upgrade the client to support the appropriate SSL cipher suite.

C : Select the appropriate "SSL Profile (Client)" in the virtual server settings.

D : Adjust the SSL key length in the SSL profile to match the minimum required by the client.

Answer: C

Question 3

The active LTM device in a high-availability (HA) pair performs a failover at the same time the network team

reports an outage of a switch on the network.

Which two items could have caused the failover event? (Choose two.)

A : a VLAN fail-safe setting

B : a monitor on a pool in an HA group

C : the standby LTM that was rebooted

D : an Auditor role that has access to the GUI

E : the standby LTM that lost connectivity on the failover VLAN

Answer: A,B

Question 4

-- Exhibit –

-- Exhibit --

Refer to the exhibit.

A pair of LTM devices are deployed in a high-availability (HA) pair as the diagram shows. After inserting a new

rule on the firewalls, the LTM devices become Standby. The rule drops all outbound sessions to the Internet.

Only inbound connections are allowed from the Internet. There are no other changes to the environment.

What triggered the LTM device failover?

A : HA Group

B : Auto Failback

C : VLAN Failsafe

D : Gateway Failsafe

Answer: D

Question 5

An LTM Specialist is tasked with ensuring that the syslogs for the LTM device are sent to a remote syslog

server.

The following is an extract from the config file detailing the node and monitor that the LTM device is using for

the

remote syslog server:

monitor

Syslog_15002 {

defaults from udp

dest *:15002

}

node 91.223.45.231 {

monitor Syslog_15002

screen RemoteSYSLOG

}

There seem to be problems communicating with the remote syslog server. However, the pool monitor shows

that the remote server is up.

The network department has confirmed that there are no firewall rules or networking issues preventing the

LTM device from

communicating with the syslog server. The department responsible for the remote syslog server indicates that

there may

be problems with the syslog server. The LTM Specialist checks the BIG-IP LTM logs for errors relating to the

remote syslog

server. None are found. The LTM Specialist does a tcpdump:

tcpdump -nn port 15002, with the following results:

21:28:36.395543 IP 192.168.100.100.44772 > 91.223.45.231.15002: UDP, length 19

21:28:36.429073 IP 192.168.100.100.39499 > 91.223.45.231.15002: UDP, length 169

21:28:36.430714 IP 192.168.100.100.39499 > 91.223.45.231.15002: UDP, length 181

21:28:36.840524 IP 192.168.100.100.39499 > 91.223.45.231.15002: UDP, length 169

21:28:36.846547 IP 192.168.100.100.39499 > 91.223.45.231.15002: UDP, length 181

21:28:39.886343 IP 192.168.100.100.39499 > 91.223.45.231.15002: UDP, length 144

NotE. 192.168.100.100 is the self IP of the LTM device.

Why are there no errors for the remote syslog server in the log files?

A : The -log option for tcpdump needs to be used.

B : The monitor type used is inappropriate.

C : The "verbose" logging option needs to be enabled for the pool.

D : When the remote syslog sever fails, it returns to service before the timeout for the monitor has expired.

Answer: B
