Question 24

An LTM Specialist is working with an LTM device configured with 10 virtual servers on the same domain with a different key/cert pair per virtual. For examplE. ftp.example.com; ssh.example.com; ftps.example.com.

What should the LTM Specialist do to reduce the number of objects on the LTM device?

Options:

create a 0 port virtual server and have it answer for all protocols

create a 0.0.0.0:0 virtual server thus eliminating all virtual servers

create a transparent virtual server thus eliminating all virtual servers

create a wildcard certificate and use it on all *.example.com virtual servers

Question 25

A device on the network is configured with the same IP address as the management address of the active LTM device, causing the management GUI to be inaccessible.

Which two methods should the LTM Specialist use to access the LTM device in order to change the management IP address? (Choose two.)

Options:

Connect via ssh to the AOM IP address.

Connect via ssh to the management address.

Connect to the LTM device via serial connection.

Connect a monitor and keyboard to the LTM device.

Connect via ssh to the standby unit and connect via ssh across the serial link between the devices.

Question 26

An LTM device has a virtual server configured as a Performance Layer 4 virtual listening on 0.0.0.0:0 to perform routing of packets to an upstream router. The client machine at IP address 192.168.0.4 is attempting to contact a host upstream of the LTM device on IP address 10.0.0.99.

The network flow is asymmetrical, and the following TCP capture displays:

# tcpdump -nnni 0.0 'host 192.168.0.4 and host 10.0.0.99'

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

listening on 0.0, link-type EN10MB (Ethernet), capture size 96 bytes

Which option within the fastL4 profile needs to be enabled by the LTM Specialist to prevent the LTM device from rejecting the flow?

Options:

Loose Close

Loose Initiation

Reset on Timeout

Question 27

A device group is made up of four members: LTM-A, LTM-B, LTM-C, and LTM-D. An LTM Specialist makes a configuration change on LTM-B. Later, a different LTM Specialist notices a "changes pending" message on all devices. When logged into LTM-D, the LTM Specialist attempts to config-sync to the device group. The sync operation fails.

Why is the LTM Specialist on LTM-D unable to synchronize the configuration to the group?
