Refer to the exhibit.

Users receive an error when attempting to connect to the website https://website.com. The website has a DNS record of 195.56.67.90. The upstream ISP has confirmed that there is nothing wrong with the routing between the user and the LTM device.

The following tcpdump outputs have been captured:

External Vlan, filtered on IP 168.210.232.5

00:25:07.598519 IP 168.210.232.5.33159 > 195.56.67.90.https: S 1920647964:1920647964(0) win 8192

What is the problem?

Options:

The filters on the tcpdumps are incorrect.

The DNS entry for website.com is incorrect.

The virtual server 'WEBSERVICES1' is listening on the incorrect port.

The firewall is dropping the connection coming from the pool members returned to the client.

The subnet masks of the pool members of pool WebServices1 and the f5 'Internal' Vlan are incorrect.

Question 11

Questions 11

-- 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 is tasked with finding the cause of the problem.

The LTM Specialist has the tcpdump extract and knows the client software has at least one connection to a VS on port 1990. However, when a tcpdump runs on the internal VLAN, there is no record of port 1990 in the tcpdump.

Why is there no record of port 1990 in the tcpdump?

Options:

The LTM device drops the connection.

Port 1990 is a well-known port, so its use is restricted.

The LTM device performs a Port Address Translation (PAT).

The LTM device performs a Network Address Translation (NAT).
