QUESTION 24:
The configuration of the 827 ADSL router depends on tbe encapsulation method
used for the ADSL connection. What are the three common encapsulation methods?
(Choose three)
A. PPPoE
B. PPPoA
C. HDLC over ATM
D. DOCSIS
E. RFC 1483 Bridged
F. IP over ATM
Answer: A, B, E

Explanation:
Before you can successfully configure your Cisco DSL Router with Asymmetric Digital
Subscriber Line (ADSL) service, you need specific information from your Internet
Service Provider (ISP). If your ISP is unsure, unable, or unwilling to provide answers to
the questions outlined below, you may not be able to correctly configure your Cisco DSL
Router.
The most fundamental piece of information you will need is the type of DSL service. The
following lists the type of DSL services that are available and can be configured on the
Cisco 827 ADSL router:
1. Point-to-Point Protocol over Ethernet (PPPoE)
2. Point-to-Point Protocol over ATM (PPPoA)
3. RFC1483 Bridging
4. RFC1483 Routing

QUESTION 25:
Which two encapsulation methods require that an 827 ADSL router be configured
with a PPP username and CHAP password? (Choose two)
A. PPPoE with the 827 configured as a bridge.
B. PPPoE with the 827 configured as the PPPoE client.
C. PPPoA
D. RFC 1483 Bridged with the 827 configured as the PPPoE client.
E. RFC 1482 Bridged with the 827 configured as a bridge.
Answer: B, C

Explanation:
When using the Point to Point Protocol over Ethernet (PPPoE) or the Point to Point
Protocol over ATM (PPPoA), you must configure a PPP username and password to
match the settings configured from the Internet Service Provider. This is required for
both PPPoE and PPPoA in order to overcome some of the security concerns of these two
Internet access methods.

QUESTION 26:
ADSL broadband connections using the PPPoE access method typically uses which
type of user authentication method?
A. AAA authentication
B. DNIS authentication
C. Caller-ID authentication
D. PPP CHAP authentication
E. IPSec authentication
F. L2TP authentication
