Question 28 (1 point)

VLSM and CIDR have several advantages over classful routing. Which two advantages do VLSM and CIDR provide?

Question 28 options:

Each subnet in a VLSM IP address allocation must have the same netmask.

Routers can learn the correct path to discontiguous subnets with CIDR.

VLSM and CIDR allow the broadcast address to be used as an IP address for devices.

CIDR cannnot summarise routes; classful routing protocols can summarise routes.

All VLSM subnets must be the same size.

CIDR allows subnets which are not class-A, -B or –C to be advertised in routing updates.

In order to minimise network traffic, OSPF elects a single router to update a group of neighbour routers. Explain why it does this. On a LAN subnet with four routers, which of the four routers will be elected. Give the term used to name this router.

Question 34 options:

This router is known as the Designated Router, and by default it is the router with the highest IP address on any interface.

This router is known as the Designated Router, and by default it is the router with the lowest IP address on any interface.

This router is known as the Dominant Router, and by default it is the router with the lowest physical address on any interface.

This router is known as the Default Router, and it is the router with the biggest routing table.
