Question 1

An HA pair of LTM devices configured in Active-Standby mode stops responding to traffic and causes an

outage. The Active device becomes Standby, but the partner device stays in Standby mode instead of taking

over as Active. A reboot and restart of the services brings the LTM device to Active mode for a short time, but

then it goes into Standby mode again.

Which two configuration components caused this condition? (Choose two.)

Options :

A : VLAN Fail-safe

B : System Fail-safe

C : Gateway Fail-safe

D : Switch Board Failure

E : Link down on Failover

Answer: A,C

Question 2

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?

Options :

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

Question 3

Internet clients connecting to a virtual server to download a file are experiencing about 150 ms of latency and

no packet loss.

Which built-in client-side TCP profile provides the highest throughput?

Options :

A : tcp

B : tcp-legacy

C : tcp-lan-optimized

D : tcp-wan-optimized

Answer: D

Question 4

-- Exhibit –

-- Exhibit --

Refer to the exhibits.

An LTM Specialist is troubleshooting an application configured on an LTM device on a one-armed

configuration. The application is NOT working through the LTM device but does work when accessed directly

via the application servers. The virtual server 192.168.1.211:443 is configured to SNAT using the address

192.168.1.144 and references a pool with the member 192.168.10.80:443. No Client or Server SSL profiles

are associated. The LTM Specialist has collected two traffic captures to help determine the issue.

What is the problem with the configuration on the LTM device?

Options :

A :

Pool member is configured to use wrong port.

B : Pool member is configured for SSL off-loading.

C :

Virtual server is configured to use wrong port.

D :

Virtual server is configured without SSL Profiles.

Answer: A

Question 5

-- Exhibit –

-- Exhibit --

Refer to the exhibit.

The decoded TCPDump capture is a trace of a failing health monitor. The health monitor is sending the string

shown in the capture; however, the server response is NOT as expected. The receive string is set to 'SERVER

IS UP'.

What is the solution?

Options :

A :

The GET request Host header field requires a host name.

B : Incorrect syntax in send string. 'HTTP/1.1' should be 'HTTP1.1'.

C : The /test_page.html does NOT exist on the web server and should be added.

D :

Incorrect syntax in send string. 'Connection: Close' should be 'Connection: Open'.
