1. By default, how is IP traffic filtered in a Cisco router?

blocked in and out of all interfaces

blocked on all inbound interfaces, but permitted on all outbound interfaces

*****permitted in and out of all interfaces

blocked on all outbound interfaces, but permitted on all inbound interfaces

2. Which three parameters can ACLs use to filter traffic? (Choose three.)

packet size

*****protocol suite

*****source address

*****destination address

source router interface

destination router interface

3. How do Cisco standard ACLs filter traffic?

by destination UDP port

by protocol type

*****by source IP address

by source UDP port

by destination IP address

4. Which two statements are correct about extended ACLs? (Choose two)

Extended ACLs use a number range from 1-99.

Extended ACLs end with an implicit permit statement.

*****Extended ACLs evaluate the source and destination addresses.

*****Port numbers can be used to add greater definition to an ACL.

Multiple ACLs can be placed on the same interface as long as they are in the same direction.

5. Where should a standard access control list be placed?

close to the source

*****close to the destination

1. Which two statements about DSL are true? (Choose two.)

users are on a shared medium

uses RF signal transmission

*****local loop can be up to 3.5 miles (5.5km)

physical and data link layers are defined by DOCSIS

*****user connections are aggregated at a DSLAM located at the CO

2. Which two Layer 1 requirements are outlined in the Data-over-Cable Service Interface Specification (DOCSIS)? (Choose

two.)

*****channel widths

access method

maximum data rate

*****modulation techniques

compression techniques

3. Which two statements are valid solutions for a cable ISP to reduce congestion for users? (Choose two.)

use higher RF frequencies

*****allocate an additional channel

*****subdivide the network to reduce users on each segment

reduce the length of the local loop to 5.5 kilometers or less

use filters and splitters at the customer site to separate voice from data traffic

4. A technician has been asked to configure a broadband connection for a teleworker. The technician has been instructed that

all uploads and downloads for the connection must use existing phone lines. Which broadband technology should be used?

cable

*****DSL

ISDN

POTS

5. After conducting research to learn about common remote connection options for teleworkers, a network administrator has

decided to implement remote access over broadband to establish VPN connections over the public Internet. What is the result

of this solution?

A reliable connection is established at greater speeds than what is offered from dialup over POTS. Security is increased, but

username and password information are sent in plain text.

*****The connection has increased security and reliable connectivity. Users need a remote VPN router or VPN client

software.

Security and reliability are increased at a substantial loss in throughput, which is considered acceptable when supporting a

single user environment.

Reliability and security are increased without the need for additional equipment, when compared to dialup connections using

POTS.
