An LTM Specialist is investigating reports from users that SSH connections are being terminated unexpectedly.
SSH connections are load balanced through a virtual server. The users experiencing this problem are running SQL queries that take upwards of 15 minutes to return with no screen output. The virtual server is standard with a pool associated and no other customizations.
What is causing the SSH connections to terminate?

• A.The virtual server has no persistence.
• B.UDP IP ToS
• C.The pool has Reselect Retries set to 0.
• D.TCP idle timeout

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 "verbose" logging option needs to be enabled for the pool.
• B.The -log option for tcpdump needs to be used.
• C.The monitor type used is inappropriate.
• D.When the remote syslog sever fails, it returns to service before the timeout for the monitor has expired.
