Question 1
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?
Answer: B
Question 2
-- 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?
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?
Answer: D
Question 4
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?
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?
Answer: B
