Here are the answers to Thursday, September 4's Cisco practice exam questions!

A. Use HDLC on both routers.

B. Use PPP on both routers.

C. Use HDLC on the Cisco router and PPP on the non-Cisco router.

CCNA Voice:

What service can redirect a VOIP call to the PSTN when CallManager determines that there is not enough bandwidth available for a high-quality VOIP call?

Answer: When CallManager decides that there isn't enough bandwidth for a high-quality call, Automated Alternate Routing (AAR) can step in and make the call. AAR can actually reroute the call to the PSTN without user intervention - in fact, the user doesn't even have to hang up!

CCNP Certification / BSCI Exam:

Short answer: What multicast addressing range is commonly called the "local network control block"?

Answer: The - range is reserved for network protocols. Packets in this range will not be forwarded by routers, so these packets cannot leave the local segment. This block of addresses is the local network control block.
