In setting up a wireless infrastructure network, which device is used to associate a client computer to the network?
- A.
An Ethernet switch
- B.
A wireless access point
- C.
Another wireless computer
- D.
A hard-wired computer on the network
Correct Answer
B. A wireless access pointExplanation
A wireless access point is used to associate a client computer to a wireless network. It acts as a central hub that allows devices to connect to the network wirelessly. The access point receives signals from the client computer and transmits them to the network, enabling the client to access the internet or other network resources. Unlike an Ethernet switch, which is used for wired connections, a wireless access point specifically facilitates wireless connections. Another wireless computer could potentially connect to the network, but it would not be the device specifically used for association. A hard-wired computer on the network is not used to associate a client computer to the wireless network.Rate this question:

After listening for the presence of a signal on the network media, hosts A and C transmit data atthe same time. In what two ways do the hosts respond to this situation? (Choose two.)
- A.
The hosts transmit a jam signal to ensure that all hosts on the network are aware that a collision has occurred.
- B.
Because they are operating in full-duplex mode, the hosts resume listening for traffic in preparation for sending future messages.
- C.
Because the hub will temporarily block traffic from one of the hosts, that host will be allowed to-transmit once the wire is clear.
- D.
Hosts A and C are assigned shorter back off values to provide them priority to access the media for retransmission.
- E.
After the back off period of a host, the host checks to determine if the line is idle before retransmitting.
Correct Answer(s)
A. The hosts transmit a jam signal to ensure that all hosts on the network are aware that a collision has occurred.
E. After the back off period of a host, the host checks to determine if the line is idle before retransmitting.Explanation
When hosts A and C transmit data at the same time, they both respond by transmitting a jam signal. This signal is sent to inform all hosts on the network that a collision has occurred. Additionally, after a back off period, the host checks if the line is idle before retransmitting. This ensures that the host does not collide with another transmission and helps in avoiding further collisions on the network.Rate this question:

Refer to the exhibit. Hosts A and B attempt to transmit a frame at the same time and a collisionoccurs. When will host D be able to transmit?
- A.
Immediately
- B.
After sending its jam signal
- C.
After host A and host B have completed transmission
- D.
After the jam signal clears and its backoff delay expires
Correct Answer
A. ImmediatelyExplanation
After a collision occurs, all hosts involved in the collision will send a jam signal to indicate the collision. Once the jam signal clears, each host will wait for a random backoff delay before attempting to retransmit. In this case, since host D was not involved in the collision, it can immediately transmit its frame without waiting for any other hosts to complete transmission or for the backoff delay to expire.Rate this question:

What happens when the crypto key zeroize rsa command is entered on a switch configured withthe transport input ssh command on the vty lines?
- A.
A new RSA key pair is created.
- B.
The switch defaults to allowing Telnet connections only.
- C.
The switch is no longer able to make SSH connections as an SSH client.
- D.
The switch allows remote connections only after a new RSA key pair is generated.
Correct Answer
D. The switch allows remote connections only after a new RSA key pair is generated.Explanation
When the crypto key zeroize rsa command is entered on a switch configured with the transport input ssh command on the vty lines, the switch erases the existing RSA key pair. As a result, the switch is no longer able to make SSH connections as an SSH client. However, the switch allows remote connections only after a new RSA key pair is generated. This means that the switch will still accept remote connections, but only after generating a new RSA key pair.Rate this question:

Refer to the exhibit. The network administrator enters the configuration shown to allow both SSH and Telnet connections to the switch. The Telnet connections fail. What is the most likely cause of this problem?
- A.
The SSH version number is wrong.
- B.
SSH has been configured on the wrong line.
- C.
Telnet and SSH cannot be configured simultaneously.
- D.
The transport input command is configured incorrectly.
Correct Answer
D. The transport input command is configured incorrectly.Explanation
The most likely cause of the Telnet connections failing is that the transport input command is configured incorrectly. The transport input command determines which protocols are allowed for incoming connections. In this case, if the command is misconfigured and does not include Telnet as an allowed protocol, then Telnet connections will fail. The SSH configuration or version number would not affect Telnet connections. Additionally, it is possible to configure both Telnet and SSH simultaneously, so that is not the cause of the problem.Rate this question:

What is the correct order in which the STP components are chosen?
- A.
Designated ports, non designated ports, root bridge, root ports
- B.
Non designated ports, designated ports, root ports, root bridge
- C.
Root bridge, root ports, designated ports, non designated ports
- D.
Root ports, root bridge, non designated ports, designated ports
Correct Answer
C. Root bridge, root ports, designated ports, non designated portsExplanation
The correct order in which the STP components are chosen is: root bridge, root ports, designated ports, non-designated ports. This sequence follows the logical progression of the STP algorithm. First, the root bridge is determined, which is the central point of the spanning tree. Then, root ports are selected on each non-root bridge, which are the ports that provide the shortest path to the root bridge. After that, designated ports are chosen on each segment, which are the ports that forward traffic towards the root bridge. Finally, non-designated ports are left, which are the ports that are blocked to prevent loops in the network.Rate this question:

How does Spanning Tree Protocol aid network architecture?
- A.
Allows for redundant links by eliminating loops
- B.
Provides greater scalability by eliminating collisions
- C.
Reduces switch processor load by reducing broadcast traffic on trunk links
- D.
Reduces administrative overhead by sharing VLAN databases between switches across the network
Correct Answer
A. Allows for redundant links by eliminating loopsExplanation
Spanning Tree Protocol aids network architecture by allowing for redundant links while eliminating loops. This is achieved by creating a tree-like structure within the network, where only one active path exists between any two network devices. This prevents the formation of loops, which can cause broadcast storms and network congestion. By eliminating loops, the network becomes more reliable and stable, as redundant links can be utilized for backup purposes in case of link failures.Rate this question:

How are data frames identified and sent to the correct VLAN when exiting an Ethernet trunk?
- A.
Frames are forwarded to the correct VLAN based on the VLAN tag.
- B.
Frames are always forwarded to the native VLAN when exiting a trunk.
- C.
Frames are forwarded to the correct VLAN based on the source IP address.
- D.
Frames are forwarded to the correct VLAN based on information in the MAC address table.
Correct Answer
A. Frames are forwarded to the correct VLAN based on the VLAN tag.Explanation
Frames are forwarded to the correct VLAN based on the VLAN tag. This is because when a frame enters an Ethernet trunk, it is tagged with the VLAN ID. The VLAN tag allows the network devices to identify which VLAN the frame belongs to and ensure that it is forwarded to the correct VLAN. This tagging process helps in maintaining the segregation and isolation of different VLANs within the network.Rate this question:

Refer to the exhibit. All switches are configured with the default bridge priority. Which port will act as a non-designated port if all links are operating at the same bandwidth?
- A.
Fa0/1 interface of switch A
- B.
Fa0/2 interface of switch A
- C.
Fa0/1 interface of switch B
- D.
Fa0/2 interface of switch B
- E.
Fa0/1 interface of switch C
Correct Answer
A. Fa0/1 interface of switch AExplanation
The correct answer is the Fa0/1 interface of switch A. In spanning tree protocol (STP), the non-designated port is the port that is not part of the designated switch or designated bridge for a particular network segment. Since all switches are configured with the default bridge priority, the switch with the lowest MAC address will become the root bridge. In this case, switch A has the lowest MAC address. The non-designated port on the root bridge will be the one with the highest cost to reach the root bridge. Since all links are operating at the same bandwidth, the non-designated port on switch A will be the one with the highest port ID, which is the Fa0/1 interface.Rate this question:

Which two statements describe Spanning Tree Protocol? (Choose two.)
- A.
It is only used at Layer 2.
- B.
It is configured on routers.
- C.
It eliminates Layer 2 loops in network topologies.
- D.
It limits the number of valid MAC addresses allowed on a port.
- E.
It allows VLAN information to propagate to other switches in the network.
Correct Answer(s)
A. It is only used at Layer 2.
C. It eliminates Layer 2 loops in network topologies.Explanation
Spanning Tree Protocol (STP) is a Layer 2 protocol used to prevent and eliminate loops in network topologies. It accomplishes this by creating a loop-free logical topology and blocking redundant links. STP operates at Layer 2, specifically at the Data Link layer, to ensure that there is only one active path between any two network devices. It is not configured on routers as they operate at Layer 3. STP does not limit the number of valid MAC addresses on a port; this is typically controlled by other mechanisms like MAC address filtering. STP also allows VLAN information to propagate to other switches in the network, ensuring consistent VLAN configurations.Rate this question:

The correct answer is to reconfigure the VTP password to be consistent on all VTP switches. This is because the VTP password is used to authenticate and secure VTP messages between switches. If the VTP password is not consistent across all switches, they will not be able to communicate and synchronize their VLAN database information. By ensuring that the VTP password is the same on all switches, the switches will be able to successfully exchange VTP messages and keep their VLAN databases in sync.Rate this question:

A new switch is to be added to an existing network in a remote office. The network administrator does not want the technicians in the remote office to be able to add new VLANs to the switch, but the switch should receive VLAN updates from the VTP domain. Which two steps must be performed to configure VTP on the new switch to meet these conditions? (Choose two.)
- A.
Configure an IP address on the new switch.
- B.
Configure the existing VTP domain name on the new switch.
- C.
Configure all ports of both switches to access mode.
- D.
Configure the new switch as a VTP client.
- E.
Enable VTP pruning.
Correct Answer(s)
B. Configure the existing VTP domain name on the new switch.
D. Configure the new switch as a VTP client.Explanation
To meet the given conditions, the network administrator needs to perform two steps. Firstly, they should configure the existing VTP domain name on the new switch. This will ensure that the switch can receive VLAN updates from the VTP domain. Secondly, they need to configure the new switch as a VTP client. This will prevent the technicians in the remote office from adding new VLANs to the switch, as only VTP servers have the ability to create and modify VLANs.Rate this question:

A switch that is using port-based memory buffering receives two incoming frames on the same port. The destination port for the first frame that is received is busy. How will the switch handle the second frame that it received?
- A.
The second frame will have to wait to be delivered even if its destination port is available.
- B.
The second frame will be delivered to the memory buffer for its destination port.
- C.
The second frame will be placed in a common memory buffer to await delivery.
- D.
The second frame will be dropped.
Correct Answer
A. The second frame will have to wait to be delivered even if its destination port is available.Explanation
When a switch using port-based memory buffering receives two incoming frames on the same port, and the destination port for the first frame is busy, the switch will handle the second frame by making it wait to be delivered, even if its destination port is available. This is because port-based memory buffering allows only one frame to be transmitted at a time on a specific port, ensuring that frames are delivered in the order they were received. Therefore, the second frame will have to wait until the first frame is delivered before it can be transmitted.Rate this question:

Which benefit is gained by designing a network with a small network diameter?
- A.
Lower latency
- B.
Improved security
- C.
Increased redundancy
- D.
Higher interface bandwidth
Correct Answer
A. Lower latencyExplanation
Designing a network with a small network diameter can result in lower latency. A smaller network diameter means that the distance between any two nodes in the network is shorter. This reduces the time it takes for data to travel between nodes, resulting in lower latency. Lower latency is beneficial as it improves the responsiveness and speed of network communication, making it ideal for real-time applications such as video streaming, online gaming, and VoIP.Rate this question:
