Question Image

An LTM Specialist is troubleshooting a problem with a new virtual server. When clients connect through the virtual server, their browsers display “The connection was reset.” Connections made directly to the pool member confirm that the application is functioning properly.

What is the issue?

  • A The pool member is failing the monitor check.
  • B The pool member default gateway is set incorrectly.
  • C The virtual server is configured with the incorrect SNAT address.
  • D The virtual server is processing encrypted traffic as plain-text HTTP.
Explanation

The virtual server accepts HTTPS traffic but applies an HTTP profile without a Client SSL profile to decrypt the TLS session. The HTTP profile therefore attempts to process encrypted HTTPS records as clear-text HTTP, producing a protocol mismatch and connection reset. A Client SSL profile is required when the virtual server is intended to terminate client-side TLS before HTTP processing.
