An LTM Specialist has configured a virtual server for www.example.com, load balancing connections to a pool of application servers that provide a shopping cart application. Cookie persistence is enabled on the virtual server. Users are able to connect to the application, but the user's shopping cart fails to update. A traffic capture shows the following:
Request: GET /cart/updatecart.php HTTP/1.1 Host: www.example.com Connection: keep-alive Cache-Control: max-age=0 User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.4 (KHTML,

What should the LTM Specialist do to resolve the problem?

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?

-- Exhibit- -- Exhibit -Refer to the exhibit. A client attempts to connect from a Google Chrome browser to a virtual server on a BIG-IP

LTM. The virtual server is SSL Offloaded. When the client connects, the client receives an SSL error. After trying Mozilla Firefox and Internet Explorer browsers, the client still receives the same errors.
The LTM Specialist does an ssldump on the virtual server and receives the results as per the exhibit.
What is the problem?

-- Exhibit-

-- Exhibit -
Refer to the exhibit.
A virtual server is set up on an LTM device as follows:
Virtual server address 78.24.213.79
Default Persistence ProfilE.source_addr, 600s.
Pool NamE.Pool1
Pool Members: 10.72.250.52:80 and 10.72.250.60:80 (both on Internal Vlan)
There are several current connections to the virtual server, and pool member
10.72.250.52:80 has been set to a "Disabled" state.
A tcpdump on the Internal Vlan shows traffic going to 10.72.250.52:80.
How soon after the persistence table query was run can existing connections be
refreshed/renewed to ensure that no requests are sent to 10.72.250.52?

-- Exhibit- -- Exhibit -


Refer to the exhibits.
A customer requests to offload SSL for an internal website. The front page of the website loads correctly; however, selecting links on the page fails.
How should the LTM Specialist fix the issue?

-- Exhibit-

-- Exhibit -Refer to the exhibit. A layer 2 nPath routing configuration has been deployed. A packet capture contains a client
connection packet with the following properties:
Source IP: <Virtual Server>
Destination IP: <Client A>
At which two locations could the packet capture have been taken? (Choose two.)

Refer to the exhibit.
The decoded TCPDump capture is a trace of a failing health monitor. The health monitor is sending the string shown in the capture; however, the server response is NOT as expected. The receive string is set to 'SERVER IS UP'.
What is the solution?

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?

An LTM Specialist has set up a custom SNMP alert.
Which command line tool should the LTM Specialist use to test the alert?

An LTM device is running BIG-IP v10.2.0 software. The LTM Specialist is tasked with upgrading the LTM device to BIG-IP v11.2.0 HF1. The LTM Specialist starts the upgrade process by selecting the uploaded Hotfix and installing to an unused volume. After 10 minutes,the LTM Specialist checks the status of the upgrade process and notices that the process is stalled at 0%.
What should the LTM Specialist verify?

There is a fault with an LTM device load balanced trading application that resides on directly connected VLAN vlan-301. The application virtual server is 10.0.0.1:80 with trading application backend servers on subnet 192.168.0.0/25. The LTM Specialist wants to save a packet capture with complete payload for external analysis.
Which command should the LTM Specialist execute on the LTM device command line interface?

An LTM Specialist must perform a packet capture on a virtual server with an applied standard FastL4 profile. The virtual server 10.0.0.1:443 resides on vlan301.
Which steps should the LTM Specialist take to capture the data payload successfully while ensuring no other virtual servers are affected?
