    Which of the following basic devices blocks ports and can sometimes filter data?

    • Repeater

    • Hub

    • Firewall

    • Switch

    Correct Answer
    A. Firewall
    Explanation
    A firewall is a basic device that blocks ports and can sometimes filter data. It acts as a barrier between a trusted internal network and an untrusted external network, monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. By blocking specific ports, a firewall can prevent unauthorized access to a network, while also filtering data to ensure that only legitimate and safe traffic is allowed through. This helps to enhance network security and protect against potential threats or attacks.

    Which of the following metrics indentifies the number of connections that is between two devices?

    • Hop count

    • MTU

    • Latency

    • Bandwidth

    Correct Answer
    A. Hop count
    Explanation
    Hop count is a metric that identifies the number of connections between two devices. It represents the number of routers or network devices that a packet must traverse to reach its destination. A higher hop count indicates a longer path and potentially more latency in the network. Therefore, hop count is a useful metric for measuring the efficiency and performance of a network connection.

    A router that takes the workstations internal IP address and changes it to another IP address when it sends the data outside of the network is and example of which of the following?

    • NAT

    • IDS

    • NMAP

    • DMZ

    Correct Answer
    A. NAT
    Explanation
    NAT stands for Network Address Translation. It is a technology used by routers to translate the internal IP addresses of devices in a private network to a different IP address when sending data outside of the network. This allows multiple devices to share a single public IP address. In this case, the router is performing NAT by changing the internal IP address of the workstation to another IP address before sending the data outside of the network.

    Karen, a technician, is asked to run new cabling for an office that is 350 feet (107 meters) away from the networking equipment. The type of cable being run is CAT6. Karen purchases and installs a 500 foot (152 meters) CAT6 cable, but after installation, notices a weak signal between the office and the networking equipment. Which of the following would have been the BEST to install instead of the CAT6 cable?

    • Install two CAT6 cables with a repeater

    • Install a 500 foot (152 meter) CAT5 cable.

    • Install a 500 foot (152 meter) CAT5e cable

    • Install three CAT6 cables with a repeater

    Correct Answer
    A. Install two CAT6 cables with a repeater
    Explanation
    Installing two CAT6 cables with a repeater would be the best option instead of the CAT6 cable. This is because the weak signal between the office and the networking equipment suggests that the distance is too long for a single CAT6 cable to maintain a strong signal. By installing two CAT6 cables and using a repeater, the signal can be boosted and maintained over the longer distance.

    Kurt, the network administrator, has just finished installing a new 10/100/1000 switch, but receives reports from the server administrator that servers connected to the new switch seem to be experiencing slow LAN connections. Kurt checks the port connecting the new switch to the core switch and sees the following information: #show run interface GigabitEthernet 0/10 Switchport trunk encapsulation dotlq Switchport mode trunk Switchport trunk native VLAN 10 Which of the following is the MOST likely cause of the slow connections?

    • The servers have not had VLAN tagging enabled on their NICs

    • Speed and duplex have not been set

    • VLAN tagging was not set on the trunk

    • The servers have been connected with CAT5 cable

    Correct Answer
    A. Speed and duplex have not been set
    Explanation
    The most likely cause of the slow connections is that the speed and duplex settings have not been configured on the port connecting the new switch to the core switch. This means that the switch and the core switch are not communicating at the optimal speed and duplex settings, resulting in slower LAN connections. Configuring the correct speed and duplex settings on the port should help resolve the issue and improve the network performance.

    Karen, an administrator, wants to list all the network connections to and from the server. Which of the following commands would MOST likely be used?

    • Traceroute

    • Ping

    • Ipconfig

    • Netstat

    Correct Answer
    A. Netstat
    Explanation
    The command "netstat" would most likely be used to list all the network connections to and from the server. Netstat is a command-line tool that displays active network connections, listening ports, and other network statistics. It provides information about the IP addresses and ports being used by the server for network communication. This command is commonly used by administrators to troubleshoot network issues and monitor network activity.

    • Coaxial

    • CAT3

    • CAT5

    • CAT5e

    Correct Answer
    A. CAT5e
    Explanation
    CAT5e should be purchased because it is capable of supporting a transmission rate of 1Gbps. Coaxial, CAT3, and CAT5 cables do not have the same level of performance and may not be able to achieve the desired transmission rate.

    Which of the following regulates the amount of network traffic a single node receives in a server cluster?

    • Load balancer

    • Proxy server

    • Content filter

    • Quality of service

    Correct Answer
    A. Load balancer
    Explanation
    A load balancer is a device or software that distributes network traffic across multiple servers or nodes in a server cluster. It helps regulate the amount of network traffic that each individual node receives by evenly distributing the workload. This ensures that no single node is overwhelmed with too much traffic, which can lead to performance issues or system failure. Therefore, a load balancer is the correct answer for regulating network traffic in a server cluster.
