Correct Answer: access-list 198 deny tcp 200.200.10.0 0.0.0.255 200.199.11.0 0.0.0.255 eq ftp
access-list 198 permit ip any 0.0.0.0 255.255.255.255
Explanation:
Extended IP access lists use numbers 100-199 and 2000-2699 and filter based on source and destination IP address, protocol number, and port number. The last option is correct because of the second line that specifies permit ip any any. (I used 0.0.0.0 255.255.255.255, which is the same as the any option.) The third option does not have this, so it would deny access but not allow everything else.
Correct Answer: access-list 100 deny tcp any 192.168.10.0 0.0.0.255 eq 23
Explanation:
The extended access list ranges are 100-199 and 2000-2699, so the access-list number of 100 is valid. Telnet uses TCP, so the protocol TCP is valid. Now you just need to look for the source and destination address. Only the third option has the correct sequence of parameters. Answer B may work, but the question specifically states "only" to network 192.168.10.0, and the wildcard in answer B is too broad.
Correct Answer: 2 and 4
Explanation:
You must have the same VTP domain name on all switches in order to share VLAN information between the switches. At least one of the switches must be a VTP server; the other switches should be set to VTP client.
Correct Answer: G
Explanation:
IEEE 802.11B is 2.4GHz, but with a maximum of only 11Mbps. IEEE 802.11G is in the 2.4GHz range, with a top speed of 54Mbps.
Correct Answer: 54Mbps
Explanation:
The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps.
Correct Answer: If no commands have been typed in 1 minute and 35 seconds, the console connection will be closed.
Explanation:
The
exec-timeout command is set in minutes and seconds.
Correct Answer: access-list 10 deny 192.168.160.0 0.0.31.255
Explanation:
The range of 192.168.160.0 to 192.168.191.0 is a block size of 32. The network address is 192.168.160.0 and the mask would be 255.255.224.0, which for an access list must be a wildcard format of 0.0.31.255. The 31 is used for a block size of 32. The wildcard is always one less than the block size.
Correct Answer: access-list 1 deny 172.16.10.1 0.0.0.0
Explanation:
Standard IP access lists use the numbers 1-99 and 1300-1999 and filter based on source IP address only. Option C is incorrect because the mask must be in wildcard format.
Correct Answer: That you have more than one access point and they are in the same SSID connected by a distribution system.
Explanation:
Extended Service Set ID means that you have more than one access point and they all are set to the same SSID and all are connected together in the same VLAN or distribution system so users can roam.
Correct Answer: Lab_A(config)#access-list 10 permit 172.16.1.1
Lab_A(config)#line vty 0 4
Lab_A(config-line)#access-class 10 in
Explanation:
Telnet access to the router is restricted by using either a standard or extended IP access list inbound on the VTY lines of the router. The command
access-class is used to apply the access list to the VTY lines.
