Click on the exhibit. After the Isp-ping command is executed, which of the following best describe the router's action?

Answer options

• A. MPLS Echo Request packets are sent within the RSVP-TE tunnel that is signaled for "lsp-toR2".
• B. MPLS Echo Request packets are sent within the LDP tunnel that is signaled for Mlsp-toR2".
• C. MPLS Echo Request packets are IP-routed to the destination address of "lsp-toR2".
• D. MPLS Echo Request packets are sent to the destination address of "lsp-toR2" over TCP.

Correct answer: A

Explanation

The correct answer is A because the Isp-ping command utilizes the RSVP-TE tunnel specifically established for 'lsp-toR2' to send MPLS Echo Request packets. Options B and D are incorrect as they refer to different tunneling protocols and transport methods that do not apply in this context, while option C mischaracterizes how the packets are routed.
