Demo Questions
Question 1
The network administrator wants to improve the performance of network transmission, what steps can the administrator take? (Choose two)
- Change the work mode to full duplex of each end station.
- Link the end stations together using a switch.
- Change the work mode to half duplex of each end station.
- Link the end stations together using a hub.
Correct answer: AB
Question 2
On Huawei switch, which of the following commands can be used to set port duplex mode as "auto negotiation"? (Choose two)
- duplex negotiation auto
- duplex auto-negotiation
- duplex auto
- undo duplex
Correct answer: CD
Question 3
The network administrator wishes to transmit data between two end stations. The network interface cards of both devices operates at 100Mbps however one supports half duplex while the other uses full duplex mode.
What will occur as a result?
- The end stations cannot communicate.
- The end stations can communicate, but data may be lost during transmission of large amounts of traffic.
- The end stations will operate normally
- The end stations can communicate, but speed is different during transmission of large amounts of traffic.
Correct answer: B
Question 4
An Ethernet port can work one of three duplex modes, whereas an Optical Ethernet port only supports one single mode.
Which of the following represents this mode?
- Full-duplex
- Half-duplex
- Auto-negotiation
- Simplex
Correct answer: A
Question 5
While inspecting packets in the network, a network administrator discovers a frame with the destination MAC address of 01-00-5E-A0-B1-C3.
What can the administrator determine from this?
- The MAC address is a unicast address.
- The MAC address is a broadcast address
- The MAC address is a multicast address.
- The MAC address is incorrect.
Correct answer: C
Question 6
According to OSI reference model, which layer is responsible for end to end error checking and flow control?
- Physical layer
- Data link layer
- Network layer
- Transport layer
Correct answer: D
Question 7
Which of the following mechanisms are used for flow control? (Choose three)
- Acknowledgement
- Buffering
- Source quench messages
- Windowing
Correct answer: BCD
Explanation:
Question 8
Refer to the capture output. The administrator has captured three packets in the network. Which statement regarding the captured packets is incorrect?
- This packets represent a TCP three-way handshake process.
- 10.0.12.1 is the telnet server, while 10.0.12.2 is the telnet client.
- The three packets contain no application data.
- 10.0.12.1 uses port 50190 to buid the telnet connection.
Correct answer: B
Question 9
An Ethernet frame is captured by network protocol analyzer tool and the value of Type/Length field is 0x0800.
Which of the following statements about the frame are correct? (Choose two)
- The frame structure of the frame is Ethernet_II
- The frame structure of the frame is 802.3
- Its upper layer protocol is IP
- Its upper layer protocol is IPX
Correct answer: AC
Explanation:
Question 10
Which of the following descriptions regarding the TTL field of the IP packet is correct?
- The TTL defines how many packets the source can send.
- The TTL defines the duration during which the source can send packets.
- The TTL value will decrement by 1 each time the packet is routed.
- The TTL value will increment by 1 each time the packet is routed.
Correct answer: C
