Users in a branch office are reporting a website is always slow. No other users are experiencing the problem. The LTM Specialist tests the website from the external VLAN along with testing the servers directly. All tests indicate normal behavior. The environment is a single HTTP virtual server on the external VLAN with a single pool containing three HTTP pool members on the internal VLAN. Which two locations are most appropriate to collect additional protocol analyzer data? (Choose two.)

• A.a user's Active Directory authentication
• B.the LTM device's internal VLAN
• C.the switch local to the user
• D.a user's machine
• E.the LTM device's external VLAN

A LTM device needs to load balance active and passive FTP traffic while using only a single virtual server. Which virtual server type should an LTM Specialist configure on the LTM device?

• A.Forwarding (Layer 2)
• B.Forwarding (IP)
• C.Standard
• D.Stateless
• E.DHCP relay

Refer to the exhibit. An LTM Specialist has created a virtual server to balance connections to a pool of application servers and offload SSL decryption. Clients connect to the application at
https://www.example.com/. The virtual server is configured with a clientssl profile but no serverssl profile. The application servers are listening on ports 80 and 443. Users are unable to connect to the application through the virtual server but are able to connect directly to the application server.
What is the root cause of the error?

• A.The pool members are configured with the wrong port.
• B.The LTM device is redirecting users to HTTPS.
• C.The LTM device is chunking responses.
• D.The application servers are redirecting users to HTTPS.

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?

• A.The server is marking the connection as closed.
• B.The 'time-until-up' setting on the monitor is incorrect.
• C.The monitor request is NOT returning the page body.
• D.The pool member is rejecting the monitor request.

The LTM device is configured to provide load balancing to a set of web servers that implement access control lists (ACL) based on the source IP address of the client. The ACL is at the network level and the web server is configured to send a TCP reset back to the client if it is NOT permitted to connect.
The virtual server is configured with the default OneConnect profile.
The ACL is defined on the web server as:
Permit: 192.168.136.0/24
Deny: 192.168.116.0/24
The packet capture is taken of two individual client flows to a virtual server with IP address
192.168.136.100.
