If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?

Discard it and send an error message back to the originating host

Flood the network with the frame

Add the source address and port to the MAC address table and forward the frame out the destination port

Add the destination to the MAC address table and then forward the frame

What is the purpose of Spanning Tree Protocol in a switched LAN?

To provide a mechanism for network monitoring in switched environments

To prevent routing loops in networks with redundant paths

To prevent switching loops in networks with redundant switched paths

To manage the VLAN database across multiple switches

To create collision domains

[#]

11.

In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?

During high-traffic periods

After broken links are reestablished

When upper-layer protocols require high reliability

In an improperly implemented redundant topology

[#]

16.

Which of the following is true when describing an anycast address?

Packets addressed to a unicast address are delivered to a single interface.

Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.

This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

[#]

17.

To enable OSPFv3, which of the following would you use?

Router1(config-if)# ipv6 ospf 10 area 0.0.0.0

Router1(config-if)# ipv6 router rip 1

Router1(config)# ipv6 router eigrp 10

Router1(config-rtr)# no shutdown

Router1(config-if)# ipv6 eigrp 10

[#]

18.

Which of the following is true when describing a unicast address?

Packets addressed to a unicast address are delivered to a single interface.

These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

These are like private addresses in IPv4 in that they are not meant to be routed.

These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
