http://img220.imageshack.us/i/acllabc.jpg/

A corporation wants to add security to its network. The requirements are:

Host C shoulb be able to use a web browser(HTTP)to access the Finance Web Server Other types of access from host C to the Finance Web Server should be blocked. All acces from hosts in the Core or local LAN to the Finance We b Server should be

blocked All hosts in the Core and local LAN should be able to acces the Plublic Web Server.

You have been tasked to create and apply a numberd acces list to a single outbound interface.

no more three statements that meets these requirements .

corp1(config)#access-list 100 permit tcp host (host address) host (finance web server address) eq 80

corp1(config)#access-list 100 deny ip any host (finance web server address)

Corp1(config)# access-list 100 permit ip any any

Corp1(config)#int fa0/1

Corp1(config-if)#ip access-group 100 out

Corp1(config-if)#end

Corp1#copy run start

Question 11 as shown above.what is the alternative notation for the IPV6 Address B514:82C3:0000:0000:0029:EC7A:0000:EC72

a) B514:82C3:0029:EC7A:EC72b) B514:82C3::0029:EC7A:EC72c) B514:82C3:0029::EC7A:0000:EC72d) 14:82C3::0029:EC7A:0:EC72

NONE OF THESE ARE RIGHT! Am I missing something?!@Adeel Khan, how can your answer be right when the 2nd to last group of hex (0000) is completely omitted and you can only use zero compression ONCE in an IPv6 address!

A correct answer would look like

B514:82C3::29:EC7A:0:EC72

if you used all available zero compression and leading zero rules. D is closest but somehow it doesn’t show B5 in the first hex grouping. This cannot be an actual question.
