第1题：

Which of the following statements correctly describe the differences between half-duplex and full-duplex Ethernet? (Select two answer choices.)

A．Full-duplex Ethernet uses CSMA/CD to prevent collisions.

B．Half-duplex Ethernet uses a loopback circuit to detect collisions.

C．A full-duplex Ethernet card allows 20Mbps for data transmission.

D．Full-duplex Ethernet makes use of two pairs of wires for data.

E．An Ethernet hub can operate both half and full duplex simultaneously.

正确答案：BD
解析：Explanation:
Half-duplex Ethernet send and receives on the same line, so a loopback needs to be set to detect collisions. Alternatively, full-duple Ethernet doesn't have to because it uses two pairs of wire, one to send and the other to receive. Collisions are not possible on full duplex Ethernet networks.

Incorrect Answers:
A. Full duplex uses both pairs of wires, so transmissions are sent on the first pair, and data that is received come in on the other pair. This prevents collisions.

C. Full duplex allows for data to be sent and received at the same time. It will not double the amount of bandwidth at any given time. The speed of the Ethernet link will remain at 10/100.

E. Hubs are shared devices and can only support one mode, unlike switches.

第2题：

In which two situations should you run the command sync group?() (Choose two.)

A. when you enable Unified Failover

B. when you create an ActiveN group

C. when you synchronize the sticky table

D. when you require synchronization of the 3G Cache objects

第3题：

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

A．Full-duplex Ethernet consists of a shared cable segment. Half-duplex provides a point-to-point link

B．Full-duplex Ethernet uses two wires to send and receive. Half-duplex Ethernet uses one wire to send and receive

C．Full-duplex Ethernet can provide higher throughput than can half-duplex Ethernet of the same bandwidth

D．Full-duplex Ethernet uses a loopback circuit to detect collisions. Half-duplex Ethernet uses a jam signal

E．None of the above

第8题：

When you compare the differences between half-duplex and full-duplex Ethernet, which of the following characteristics are exclusive to half-duplex? (Select two answer choices)

A．Half-duplex Ethernet operates in a shared collision domain.

B．Half-duplex Ethernet operates in an exclusive broadcast domain.

C．Half-duplex Ethernet has efficient throughput.

D．Half-duplex Ethernet has lower effective throughput.

E．Half-duplex Ethernet operates in an exclusive collision domain.

正确答案：AD
解析：Explanation:
A single device could not be sending a frame. and receiving a frame. at the same time because it would mean that a collision was occurring. So, devices simply chose not to send a frame. while receiving a frame. That logic is called half-duplex logic.

Ethernet switches allow multiple frames to be sent over different ports at the same time. Additionally, if only one device is connected to a switch port, there is never a possibility that a collision could occur. So, LAN switches with only one device cabled to each port of the switch allow the use of full-duplex operation. Full duplex means that an Ethernet card can send and receive concurrently.

Incorrect Answers:
B. Full duplex effectively doubles the throughput of half-duplex operation, because data can be both sent and received at the full 10/100 speed.

C, E. In half duplex operation, the network is shared between all devices in the collision domain.

第9题：

In Ethernet networks, duplex mismatches will lower performance. Which error statistics can be seen if a duplex mismatch is present?()

A.collisions on the full-duplex side; runts on the half-duplex side

B.collisions on the full-duplex side; collisions on the half-duplex side

C.collisions on the half-duplex side; framing errors on the full-duplex side

D.collisions on the half-duplex side; giants on the full-duplex side
