1. If a network has converged, what is true about the link-state database held by each router in the same OSPF area?

Each router has a link-state database containing the same status information.

Each router has a different link-state database depending on its position within the network.

The link-state database is stored in a designated router and is accessed by each router in the area as needed.

The link-state database in each router only contains information about adjacent routers and the status of their links.


2. What is always required for OSPF routers to share routing information?

designated routers

a backup designated router

neighbor adjacencies

an NBMA network topology

links that are configured on the network

1. What are two benefits of implementing a VLSM addressing scheme? (Choose two.)

allows efficient use of address space

supports hierarchical addressing capability

supports only one subnet mask length throughout the entire network

allows efficient use of larger routing tables to eliminate the need for route summarization

solves the problem of discontiguous networks with classful routing protocols


2. When running NAT, what is the purpose of address overloading?

limit the number of hosts that can connect to the WAN

allow multiple inside addresses to share a single global address

force hosts to wait for an available address

allow an outside host to share inside global addresses

1. Which statement describes a difference between STP and RSTP?

RSTP is proprietary while STP is defined by IEEE.

RSTP defines four port states while STP defines five port states.

When a topology changes, RSTP reconfigures the spanning tree in less than 1 second.

STP is more commonly used in large switched enterprise networks that require faster recovery.


2. In an enterprise network, why would voice traffic typically require a dedicated VLAN?

It guarantees end-to-end delivery for voice traffic.

It guarantees higher bandwidth for voice traffic.

It separates voice traffic from data traffic so data traffic does not impact voice traffic.

It provides backup support for voice traffic because voice traffic is more critical than data traffic.
