A) PAP

B) dot1x

C) IPSec

D) CHAP

E) ESP

Question 3

A) TCP adjust.

B) Dialer persistent

C) PPPoE Groups.

D) half-bridging

E) Peer Neighbor Route

Question 4

A) MS CHAP

B) CDPCP

C) CHAP

D) PAP

Question 5

Which protocol uses dynamic address mapping to request the next-hop protocol address for a specific connection?

A) Frame Relay inverse ARP

B) static DLCI mapping

C) Frame Relay broadcast queue.

D) dynamic DLCI mapping

Question 6

What is the default OSPF hello interval on a Frame Relay point-to-point network ?

A) 10

B) 20.

C) 30.

D) 40.

Question 7

PPPoE is composed of which two phases ?

A) Active authentication phase and PPP session phase.

B) Passive discovery phase and PPP session phase.

C) Active authorization phase and PPP session phase.

D) Active Discovery phase and PPP session phase.

Question 8

Which statement is true about the PPP Session Phase of PPPoE ?

A) PPP options are negotiated and authentication is not performed. Once the link setup is completed, PPPoE functions as a Layer 3 encapsulation method that allows data to be transferred over the PPP link within PPPoE headers.

B) PPP options are not negotiated and authentication is performed. Once the link setup is completed, PPPoE functions as a Layer 4 encapsulation method that allows data to be transferred over the PPP link within PPPoE headers.

C) PPP options are automatically enabled and authorization is performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation method that allows data to be encrypted over the PPP link within PPPoE headers.

D) PPP options are negotiated and authentication is performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation method that allows data to be transferred over the PPP link within PPPoE headers.
