Question 71

An application is configured on an LTM device:
Virtual server: 10.0.0.1:80 (VLAN vlan301)
SNAT IP: 10.0.0.1
Pool members: 10.0.1.1:8080, 10.0.1.2:8080, 10.0.1.3:8080 (VLAN vlan302)
Which packet capture should the LTM Specialist perform on the LTM device command line interface to capture only client traffic specifically for this virtual server?

    Refer to the exhibit.
    An LTM Specialist is troubleshooting a sync-failover group of three BIG-IP LTM devices. The command used is "tmsh run cm watch-devicegroup-device."
    What does the output mean?
  • Question 73

    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?
  • Question 74

    A client (10.10.1.30) connecting to an HTTPS virtual server (10.10.1.100) with a clientssl profile is getting an SSL error.
    Which options will trace this issue?
  • Question 75

    A stand-alone LTM device is to be paired with a second LTM device to create an active/standby pair. The current stand-alone LTM device is in production and has several VLANs with floating IP addresses configured.
    The appropriate device service clustering (DSC) configurations are in place on both LTM devices.
    Which two non-specific DSC settings should the LTM Specialist configure on the second LTM device to ensure no errors are reported when attempting to synchronize for the first time? (Choose two.)
