Question 4

OSPF -Open Shortest Path First

Answer 4

The OSPF metric is based on cumulative bandwidth from source to destination

Question 5

EIGRP

Answer 5

uses a metric based on minimum bandwidth, delay, load and reliability

Question 6

Default Static Route

Answer 6

Typically used as a Gateway of Last Resort, which is used for any packet that does not have a destination route in the routing table

Question 7

Dual Stack

Answer 7

Dual Stack means that a device runs both Ipv4 and ipv6 protocols simultaneously. Using two stacks allows both Ip version to coexist

Question 8

Tunneling

Answer 8

Tunneling is used when Ipv6 addresses are sent over IPv4 networks or vice versa. IPv6 packets is encapsulated within a Ipv4 packet

Question 9

Cisco Discovery Protocol (CDP)

Answer 9

is a layer 2 cisco proprietary protocol enabled by default on all cisco devices. Its purpose is similar to the purpose of NDP.

Question 10

Cisco Discovery Protocol (CDP) 2

Answer 10

includes a unique feature that can detect a protocol-connection mismatch

Question 11

Answer 11

Cisco recommends to place this type of ACL as close to the destination device as possible

Question 12
