lan internet lan | 4050. When you compare the differences between half-duplex and full-duplex Ethernet, which of the following characteristics are exclusive to half-duplex?

1. Half-duplex Ethernet operates in an exclusive broadcast domain.
2. Half-duplex Ethernet operates in a shared collision domain.
3. None of the above
4. Half-duplex Ethernet has efficient throughput.

4051. What is the IEEE standard associated with Gigabit Ethernet?

1. 802.3ab
2. 802.11
3. 802.5
4. 802.3ae

4052. What is a valid reason to assign ports on VLANs on a new LAN switch?

1. To make VTP easier to implement
2. To allow more devices to connect to the network
3. To increase the size of the collision domain
4. To isolate broadcast traffic

4053. You are experiencing intermittent issues relating to congestion within the network. What are the possible causes of congestion on this LAN?

1. Multicasting
2. A broadcast domain with too many hosts.
3. None of the above
4. Full duplex operation.

4054. You want to upgrade the LAN so that all ports operate in full duplex mode. Which statement is true about full-duplex Ethernet when comparing to half-duplex Ethernet?

1. Full-duplex Ethernet consists of a shared cable segment. Half-duplex provides a point-to-point link
2. Full-duplex Ethernet can provide higher throughput than can half-duplex Ethernet of the same bandwidth
3. Full-duplex Ethernet uses two wires to send and receive. Half-duplex Ethernet uses one wire to send and receive
4. Full-duplex Ethernet uses a loopback circuit to detect collisions. Half-duplex Ethernet uses a jam signal

4055. Company is installing IP phones in a new office. The phones and office computers connect to the same device. To ensure maximum throughout for the phone data sessions, the company needs to make sure that the phone traffic is on a different network from that of the office computer data traffic. What is the best network device to which to directly connect the phones and computers and what technology should be implemented on this device?

1. Subinterface
2. VLAN
3. Hub
4. STP

4056. The network administrator needs to add a switch named PC1 to become the root bridge for a redundant path switched network. What can be done to ensure that PC1 will always assume the role as the root bridge?

1. Assign the switch a higher MAC address than the other switches in the network have
2. Establish a direct link from the switch to all other switches in the network
3. Configure the switch full-duplex operation and configure the other switches for half-duplex operation
4. Configure the switch so that it has lower priority than other switches in the network

4057. 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.

4058. 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

4059. 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
