1.
The following commands were entered on a
router: Router(config)# access-list 2 deny 172.16.5.24 Router(config)# access-list 2 permit any What can be concluded about this set of commands? | |
The access list statements are misconfigured. | |
All nodes on 172.16.0.0 will be denied access when these statements are applied. | |
The default wildcard mask, 0.0.0.0 is assumed. | |
The default wildcard mask 255.255.255.255 is assumed. |
ACL statements operate in sequential, logical order. If a
condition match is true, the rest of the ACL statements are not checked. If all
of the ACL statements are unmatched, what happens to the packet? | |
The packets will be placed in a buffer and forwarded when the ACL is removed. | |
The packets will be sent to the source with an error notification message. | |
The implicit permit any statement placed at the end of the list will allow the packets to flow through uninhibited. | |
The implicit deny any statement placed at the end of the list will cause the packets to be dropped. |
Select the statements that describe ACL processing of packets.
(Choose three.) | |
An implicit deny any rejects any packet that does not match any ACL statement. | |
A packet can either be rejected or forwarded as directed by the statement that is matched. | |
A packet that has been denied by one statement can be permitted by a subsequent statement. | |
A packet that does not match the conditions of any ACL statements will be forwarded by default. | |
Each statement is checked only until a match is detected or until the end of the ACL statement list. | |
Each packet is compared to the conditions of every statement in the ACL before a forwarding decision is made. |
Choose the command that will correctly configure a standard ACL.
| |
Router# access-list 10 permit any | |
Router# access-list 101 permit any | |
Router(config)# access-list 10 permit any | |
Router(config)# access-list 101 permit any | |
Router(config)# access-list 10 permit any any |
Choose the commands that will correctly configure a standard ACL.
(Choose two.) | |
Router(config)# access-list 97 permit host
192.5.5.1 | |
Router(config)# access-list 32 permit
210.93.105.3 0.0.0.0 | |
Router(config)# access-list 148 permit
201.100.11.2 0.0.0.0 | |
Router(config)# access-list 107 permit host
192.5.5.1 213.45.27.0 0.0.0.255 eq 23 | |
Router(config)# access-list 10 permit tcp
192.5.5.1 0.0.0.255 201.100.11.0 0.0.0.255 eq 80 |
Which of the following parameters can ACLs use to filter traffic?
(Choose three.) | |
packet size | |
protocol suite | |
source address | |
destination address | |
source router interface | |
destination router interface |
Which of the following matches an ACL identification number with
the correct protocol?(Choose three.) | |
0 - standard IP | |
99 - standard IP | |
100 - extended IP | |
210 - extended IP | |
678 - extended IPX | |
888 - standard IPX |
Select the correct statements 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. |
The router IOS tests each condition statement in an ACL in
sequence. Once a match is made, which of the following occurs? (Choose two.)
| |
The entire ACL must be deleted and recreated. | |
The accept or reject action is performed. | |
The packet is forwarded to the next hop. | |
The remaining ACL statements are not checked. | |
The router goes through the list again to verify that a match has been made. |
