4030. The system LED is amber on a new Catalyst 2950 series switch. What does this indicate?

1. The system is malfunctioning.
2. The system is powered up and operational.
3. The system is sensing excessive collisions.
4. The system is forwarding traffic.

4031. Users have noticed extremely slow network performance, intermittent connectivity, and connection losses. After entering the "show interfaces" command, you notice that the Ethernet interface is configured as 100 Mbps full-duplex and that there is evidence of late collisions. What could be the cause of this problem?

1. Duplex mismatch
2. Trunking mode mismatch
3. A routing loop
4. Improperly configured root bridge

4032. PC1 is a switch in the network. Why will PC1 never learn the broadcast address?

1. A broadcast frame is never forwarded by a switch
2. Broadcasts only use network layer addressing
3. Broadcast frames are never sent to switches
4. A broadcast address will never be the source address of a frame

4033. Which of following VLAN frame encapsulation types are configurable on a Cisco switch?

1. 802.1Q
2. None of the above
3. LLC
4. VTP

4034. Why is full-duplex Ethernet superior to its single-duplex counterpart?

1. It uses inexpensive hubs
2. It operates on switches
3. It operates without collisions
4. None of the above

4035. In which circumstance are multiple copies of the same unicast frame likely to be transmitted in the Switched LAN?

1. After broken links are re-established
2. When upper-layer protocols require high reliability
3. During high traffic periods
4. In an improperly implemented redundant topology

4036. The network administrator needs to determine what LAN devices to install on the network. What are advantages of using Layer 2 Ethernet switches over hubs?

1. Increasing the size of broadcast domains
2. Filtering packets based on MAC addresses
3. Allowing simultaneous frame transmissions
4. Increasing the maximum length of UTP cabling between devices

4037. What basic functions do their routers perform in a network?

1. Bridging between LAN segments
2. Route switching
3. The microsegmentation of broadcast domains
4. Path selection

4038. The network administrator wants to use a router named PC1 to segment the local network. What are some of the advantages of using PC1 to segment the network?

1. Filtering can occur based on Layer 3 information
2. Broadcasts are eliminated
3. Routers generally cost less than switches
4. None of the above

4039. The corporate LAN consists of one large flat network. You decide to segment this LAN into two separate networks with a router. What will be the affect of this change?

1. The number of broadcast domains will be decreased
2. It will make the broadcasting of traffic between domains more efficient between segments.
3. It will increase the number of collisions.
4. It will prevent segment 1’s broadcasts from getting to segment 2.
