Q

What is Administrative Distance (AD)?

A

A number of an arbitrary unit assigned to dynamic routes and static routes. Low AD is more preferred than high AD.

Q

What is the Network Address Translation (NAT)?

A

Used to converse the limited supply of IPv4 addresses

Translates private IPs to public IPs for routing over public networks

17
Q

What is the Port Address Translation (PAT)?

A

A variation of address translation that utilizes port numbers instead of IP addresses for translation

18
Q

What is the Internet Group Management Protocol (IGMP)?

A

Used by clients and routers to let routers known which interfaces have multicast receivers

19
Q

What is Multicast Flooding?

A

No specific host is associated with the multicast MAC address in the CAM table of the switch
