QUESTION NO: 7

Given the configuration

Access-list 101 permit ip any any

Access-list 1.1 deny TCP any any eq ftp

Dialer list 2 protocol IP list 101

Why does the configuration fail to prevent FTP traffic from dialing the line?

Trang 6

A The final configuration line allows all IP traffic to be forwarded

B The terms “any any” in the deny line allow FTP to be forwarded

C Since FTP uses two sockets, both must be defined to prevent packet forwarding

D The “deny” restriction is read after the “permit” line has already allowed packet forwarding

Answer: D

Explanation: The access lists are matched in order Only the first matching access list is

applied In this scenario the first access list:

Access-list 101 permit ip any any

is applied It will permit any traffic We should swap the order of the access list so that the deny access list is applied first

Answer: C

Explanation: WAN technologies such as Frame Relay, ATM, X.25, and SMDS require

that the header information be untouched so that it can be read by the individual switches that the transmission crosses Any implementation of virtual circuits disallows link

compression In these cases, payload compression is appropriate

A: Link compression compresses the complete packet, including the header Link

compression cannot be used for WAN switching technologies, such as frame relay

B: Only compressing the Headers would not maximize the usage

D: The Predictor compression method attempts to predict the coming character

sequences However, Predictor compression cannot directly be used on WAN links It

is used by link compression for example
