Question 1

The LTM device is configured for RADIUS authentication. Remote logins are failing and the LTM Specialist must verify the RADIUS configuration.

How should the LTM Specialist check the RADIUS server and shared secret configured on the LTM device?

Atmsh show running-config /auth radius

Btmsh show running-config /sys auth radius

Ctmsh show running-config /auth configuration

Dtmsh show running-config /sys auth radius-server

Answer : A

Question 2

An active/standby pair of LTM devices deployed with network failover are working as desired. After external personnel perform maintenance on the network, the LTM devices are active/active rather than active/standby. No changes were made on the LTM devices during the network maintenance.

Which two actions would help determine the cause of the malfunction? (Choose two.)

Achecking that the configurations are synchronized

Bchecking the configuration of the VLAN used for failover

Cchecking the configuration of the VLAN used for mirroring

Dchecking the open ports in firewalls between the LTM devices

Echecking synchronization of system clocks among the network devices

Answer : B, D

Question 3

A new VLAN vlan301 has been configured on a highly available LTM device in partition Application A . A new directly connected backend server has been placed on vlan301. However, there are connectivity issues pinging the default gateway. The VLAN self IPs configured on the LTM devices are 192.168.0.251 and 192.168.0.252 with floating IP 192.168.0.253. The LTM Specialist needs to perform a packet capture to assist with troubleshooting the connectivity.

Which command should the LTM Specialist execute on the LTM device command line interface to capture the attempted pings to the LTM device default gateway on VLAN vlan301?

Atcpdump -ni /ApplicationA/vlan301 'host 192.168.0.253'

Btcpdump -ni vlan301 'host 192.168.0.253'

Ctcpdump -ni /ApplicationA/vlan301 'host 192.168.0.251 or host 192.168.0.252'

Dtcpdump -ni vlan301 'host 192.168.0.251 or host 192.168.0.252'

Answer : A

Question 4

-- Exhibit --

Refer to the exhibit.

An LTM Specialist is troubleshooting a new HTTP monitor on a pool. The pool member is functioning correctly when accessed directly through a browser. However, the monitor is marking the member as down. The LTM Specialist captures the monitor traffic via tcpdump.

What is the issue?

AThe server is marking the connection as closed.

BThe pool member is rejecting the monitor request.

CThe monitor request is NOT returning the page body.

DThe 'time-until-up' setting on the monitor is incorrect.

Answer : C

Question 5

-- Exhibit --

Refer to the exhibit.

A company uses a complex piece of client software that connects to one or more virtual servers (VS) hosted on an LTM device. The client software is experiencing issues. An LTM Specialist must determine the cause of the problem.

The LTM Specialist is seeing a client source IP of 168.210.232.5 in the tcpdump. However, the client source IP is actually 10.123.17.12.

Why does the IP address of 10.123.17.12 fail to appear in the tcpdump?

AThe LTM device performed NAT on the individual's IP address.

BThe Secure Network Address Translation (SNAT) pool on the virtual server is activated.

CNetwork Address Translation (NAT) has occurred in the path between the client and the LTM device.

DThe individual's data stream is being routed to the LTM device by a means other than the default route.

Answer : C

Question 6

Given a tcpdump on an LTM device from both sides of a connection on the External and Internal VLANs, how should an LTM Specialist determine if SNAT is enabled for a particular pool?

Aby checking to see if the Source IP is carried through from the External Vlan to the Internal Vlan

Bby checking to see if the Destination port is carried through from the External Vlan to the Internal Vlan

Cby checking to see if the Source port is carried through from the External Vlan to the Internal Vlan

Dby checking to see if the Destination IP is carried through from the External Vlan to the Internal Vlan

Answer : A

Question 7

In which file would the LTM Specialist find virtual server configurations?

Abigip.conf

Bbigip_sys.conf

Cbigip_base.conf

Dprofile_base.conf
