Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 11

An engineer is performing an international multisite deployment and wants to create an effective backup method to access TEHO destinations in case there is a call failure through the primary route. Which technology provides this ability?

Answer options

• A. CFUR
• B. LRG
• C. AAR
• D. SRST

Correct answer: A

Explanation

CFUR (Call Forward Unreachable) is designed to reroute calls to alternate destinations when the primary route is unavailable, making it the correct choice. LRG (Location Route Group), AAR (Automated Alternate Routing), and SRST (Survivable Remote Site Telephony) do not specifically address the need for accessing TEHO destinations in this context.
