An ________ _________ ________ is a security device that monitors system or network activity and then notifies the administrator of any suspicious activity.
Explanation
Intrusion detection systems are important devices that will complement other security devices such as firewalls. The IDS is an important device because it will notify you not only of suspicious activity against the firewall, but also of suspicious activity inside the network.Rate this question:
- 8.
A _______-based IDS monitors network traffic for suspicious behavior.
Explanation
A network-based IDS has the capability of monitoring the entire network and comparing that traffic to known malicious traffic patterns. When a match is found an alert can be triggered. Network-based IDSs can be software loaded on a system that monitors network traffic or can be a hardware device.Rate this question:
- 9.
An ______ IDS will monitor activity, log any suspicious activity, and then take some form of corrective action. For example, if a system is doing a port scan on the network, the IDS may log the activity but also disconnect the system creating the suspicious action from the network.
Explanation
An active IDS refers to an intrusion detection system that actively monitors network activity, logs any suspicious behavior, and takes necessary corrective actions. In this case, if the system detects a port scan, it not only logs the activity but also disconnects the system responsible for the suspicious action from the network. This proactive approach ensures that potential threats are immediately addressed and mitigated to prevent any further damage or unauthorized access.Rate this question:
- 10.
A ______ intrusion detection system does not take any corrective action when suspicious activity has been identified. It will simply identify the activity and then log to file any information needed during an investigation. It does not take any corrective action.
Explanation
A passive intrusion detection system is designed to only identify and log suspicious activity without taking any corrective action. It is primarily used for monitoring and collecting information about potential security threats, allowing for further investigation and analysis. Unlike an active intrusion detection system, which may actively block or mitigate suspicious activity, a passive system focuses on passive observation and documentation.Rate this question:

A _______ is responsible for translating information from one format to another and can run at any layer of the OSI model, depending on what information it translates. A typical use is to ensure that systems in one environment can access information in another environment.
Correct Answer
gatewayExplanation
For example, you want to make sure that your PC environment can access information on the company’s mainframe. As shown in the Figure, when the packet reaches the gateway, the gateway strips the packet down and repackages it so that it is understood on the other side of the gateway.
It is also important to note that when you configure TCP/IP and you configure the “default gateway” setting, you are pointing to the address of the router on the network. It really has nothing to do with an actual “gateway” device.Rate this question:

One disadvantage of using a hub is that it leads to a lot of unneeded traffic and contention across the entire network that will slow network performance.
-
True
-
False
Correct Answer
A. TrueExplanation
A hub sends the signal to all ports on the hub. This means that, if you have a 24-port hub linked to another 24-port hub and a workstation sends data to another workstation, the data will be sent to all 48 ports on the network. This leads to a lot of unneeded traffic and contention across the
entire network that will slow network performance. A solution would be to use a switch, which is the subject of an upcoming discussion!Rate this question:
-
- 29.

Hubs are used in Ethernet environments, whereas Token Ring environments use MAUs.
-
True
-
False
Correct Answer
A. TrueExplanation
Hubs and MAUs are both used in networking environments, but they are specific to different types of networks. Hubs are used in Ethernet environments, where they act as a central connection point for multiple devices. They receive data from one device and then broadcast it to all other devices connected to the hub. On the other hand, MAUs (Media Access Units) are used in Token Ring environments. They provide the physical connection between devices in a Token Ring network, allowing them to transmit data in a controlled manner. Therefore, the statement that hubs are used in Ethernet environments and MAUs are used in Token Ring environments is true.Rate this question:
-
- 31.
It is a best practice to use switches whenever possible because of the increase in performance over a standard hub. The bandwidth with a standard hub is shared by all users connected to the hub; however, with a switch, all users get the full network bandwidth. For example, a 100 Mbps network with a 24-port hub and 24 PCs allows each user to have 100/24 Mbps bandwidth; with a switch, however, each user would have a full 100 Mbps bandwidth.
-
True
-
False
Correct Answer
A. TrueExplanation
Using switches instead of standard hubs is considered a best practice because it improves performance. In a standard hub, the bandwidth is shared among all connected users, resulting in slower speeds for each user. However, with a switch, each user gets the full network bandwidth, which leads to faster and more efficient data transmission. This is demonstrated in the example provided, where a 100 Mbps network with a 24-port hub and 24 PCs would give each user only 100/24 Mbps bandwidth, whereas with a switch, each user would have the full 100 Mbps bandwidth.Rate this question:

MAUs don't have collision indicators because you can't have collisions on a Token Ring network.
-
True
-
False
Correct Answer
A. TrueExplanation
Token Ring networks use a token passing mechanism where only one device can transmit data at a time. Each device on the network waits for its turn to transmit, eliminating the possibility of collisions. Therefore, collision indicators are not necessary in Token Ring networks as collisions cannot occur. Therefore, the given statement is true.Rate this question:

A thinnet segment cannot be attached directly to the BNC connector on the network adapter; it must use a T-connector.
-
True
-
False
Correct Answer
A. TrueExplanation
A thinnet segment cannot be attached directly to the BNC connector on the network adapter because it requires the use of a T-connector. This connector is necessary to connect the thinnet cable to the network adapter, allowing for proper communication and data transmission. Without the T-connector, the thinnet segment would not be able to establish a connection with the network adapter and therefore would not function correctly.Rate this question:

-
It provides faster communication between the CPU and the hard disk.
-
It provides the capability to communicate across a phone line to another computer.
-
It provides the capability to communicate with other computers across a network medium.
-
It provides the capability to save more information on a diskette than normal.
Correct Answer
A. It provides the capability to communicate with other computers across a network medium.Explanation
A network interface card (NIC) adds the capability to communicate with other computers across a network medium. This means that the computer can connect to other devices, such as servers or other computers, and exchange data or access shared resources. The NIC acts as the interface between the computer and the network, allowing it to send and receive data packets. Without a NIC, the computer would not be able to connect to a network and would be limited to local functionality only.Rate this question:

Virtual LANs (VLANs) are a feature of special switches, known as __________ switches, which allow the administrator to group ports on a switch to a “virtual LAN.” When a port is configured for a particular VLAN, it is unable to communicate with systems that are not on that VLAN without the use of a routing device such as a router. This is similar to the fact that, if we had two physical networks, a machine cannot send data from one network to the other without the use of a router.
Correct Answer
managedExplanation
Managed switches are special switches that have the capability to create and manage VLANs. By grouping ports on a switch to a "virtual LAN," the administrator can control the communication between devices on different VLANs. When a port is configured for a particular VLAN, it is isolated from other VLANs and can only communicate with devices within the same VLAN. This is similar to how a machine in one physical network cannot send data to another network without the use of a router. Therefore, the correct answer is "managed."Rate this question:

8. Which network component is used to extend the distance the signal can travel by regenerating the signal?
-
Passive hub
-
Switch
-
Router
-
Repeater
Correct Answer
A. RepeaterExplanation
A repeater is a network component that is used to extend the distance the signal can travel by regenerating the signal. It receives the signal, amplifies it, and then retransmits it to the next segment of the network. This helps to overcome signal degradation and allows the signal to travel further without loss of quality. Unlike a passive hub, switch, or router, which primarily facilitate communication between devices, a repeater specifically focuses on boosting the signal strength to extend its reach.Rate this question:

MAUs don't use an uplink port?
-
True
-
False
Correct Answer
A. TrueExplanation
Another major difference with a MAU is that MAUs don’t actually use an uplink port. With Token Ring, there is a logical ring within the MAU, and when you connect to another MAU, you must complete a full ring structure again. Therefore, you will notice on the Token Ring MAU that it has a ring-in port and a ring-out port. When you wish to connect two MAUs together, you must ring out of the first MAU and, with that cable, ring in to the second MAU.Rate this question:

16. Which layer of the OSI model does a router run at?
-
Layer 4
-
Layer 1
-
Layer 3
-
Layer 2
Correct Answer
A. Layer 3Explanation
A router operates at Layer 3 of the OSI model, which is the network layer. This layer is responsible for routing and forwarding data packets between different networks. Routers use IP addresses to determine the best path for forwarding packets to their destination. They make decisions based on routing protocols and maintain routing tables to efficiently direct traffic. Therefore, Layer 3 is the correct answer for the layer at which a router operates.Rate this question:
-
- 44.
This layer switch doesn’t associate the port with the VLAN, but the MAC addresses of systems are associated with the VLAN. The network administrator is responsible for listing all the MAC addresses for each VLAN on the switch. When a packet is sent by a system and reaches the switch, the switch tags the packet as being a member of the VLAN, and it will be sent only to other systems in the VLAN. The benefit of this layer switches is that, because the MAC address is associated with the VLAN, it doesn’t matter what port the system is plugged into. This is a great feature for laptop users who typically roam around on the network—they will always be a member of the same VLAN unless the switch is reconfigured.
-
Layer 1
-
Layer 2
-
Layer 3
Correct Answer
A. Layer 2Explanation
Layer 2 switches are responsible for associating MAC addresses with VLANs. When a packet reaches the switch, it tags the packet as a member of a specific VLAN based on the MAC address. This allows the switch to send the packet only to other systems in the same VLAN, regardless of the port the system is connected to. This feature is particularly beneficial for laptop users who move around on the network, as they will always remain a member of the same VLAN unless the switch is reconfigured.Rate this question:

12. Which type of network component enables each device to have the full bandwidth of the medium when transmitting?
-
Hub
-
Repeater
-
Switch
-
Transceiver
Correct Answer
A. SwitchExplanation
Switching is a fairly involved process that allows the device to have the full bandwidth when transmitting.
The Transceiver is incorrect because a transceiver is the connection point on a NIC and does not allow for multiple users to send data through the transceiver. The bandwidth on the transceiver is dedicated to the PC in which the NIC is installed.
The Hub is incorrect because the bandwidth is divided among all used ports on the hub.
The Repeater is incorrect because it does not split bandwidth, inasmuch as it is used only to receive signals on one cable and regenerate the signal on another cable.Rate this question:
