Here are the answers....and be sure to watch the CCNA Video Boot Camp at the bottom of this page!
1. (B). In short, "INACTIVE" means the problem is at the other end, "DELETED" means the problem is at your end.
2. Features that PPP offers that HDLC does not includes data compression options, multilink, encryption options, and dialer callback.
That version of HDLC is also Cisco-proprietary, so if non-Cisco devices are part of the communication, you'd need to use PPP.
3. (A, D). Always use the local DLCI and remote IP address in frame map statements.
4. (B). Inverse ARP, sometimes referred to as iARP, created those dynamic frame mappings. Inverse ARP runs by default on a frame relay interface, and can be disabled with the no frame inverse-arp command.
