Question 1

An LTM Specialist has a OneConnect profile and HTTP profile configured on a virtual server to load balance an HTTP application.

The following HTTP headers are seen in a network trace when a client connects to the virtual server:

Clientside:

GET / HTTP/1.1

Host: 192.168.136.100

User-Agent: Mozilla/5.0

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

Accept-EncodinG. gzip, deflate

Connection: keep-alive

Serverside:

HTTP/1.1 200 OK

DatE. 5 Jun 1989 17:06:55 GMT

Server: Apache/2.2.14 (Ubuntu)

Vary: Accept-Encoding

Content-EncodinG. gzip

Content-LengtH. 3729

X-Cnection: close

Content-TypE. text/html

The LTM Specialist notices the OneConnect feature is working incorrectly.

Why is OneConnect functioning incorrectly?

AClient must support HTTP/1.0.

BClient must support HTTP keep-alive.

CServer must support HTTP/0.9.

DServer must support HTTP keep-alive.

Answer : D

Answer : D

Question 4

An application owner claims an LTM device is delaying delivery of an HTTP application. The LTM device has two VLANs, an internal and an external. The application servers reside on the internal VLAN. The virtual server and clients reside on the external VLAN.

With appropriate filters applied, which solution is most efficient for obtaining packet captures in order to investigate the claim of delayed delivery?

Aone capture on interface 0.0

Bone capture on the internal interface

Cone capture on the external interface

Done capture on the management interface

Answer : A

Question 5

-- Exhibit --

Refer to the exhibit.

An LTM Specialist is reviewing the 'test' partition.

Which objects, in order, can be removed from the partition?

Adelete pool test1_pool, delete node 10.1.1.2

Bdelete node 10.1.1.2, delete pool test2_pool

Cdelete pool test1_pool, delete node 10.1.1.2, delete node 10.1.1.1

Ddelete virtual test1_vs, delete pool test2_pool, delete node 10.1.1.1

Edelete pool test1_pool, delete pool test2_pool, delete node 10.1.1.3

Answer : A

Question 6

There are three servers in the pool: 172.16.20.1, 172.16.20.2, and 172.16.20.3, with the virtual IP address 10.0.20.88.

A user CANNOT connect to an HTTP application. To understand the problem and find a solution, the LTM Specialist runs two concurrent traces on the LTM device, with the following results:

Trace on client side:

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

Answer : D

Question 7

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'
