    A user is unable to connect to the network. A network technician is able to determine that there is a problem on the switch. All other users on that switch are able to connect successfully to the network. Which of the following is a probable cause?

    • Switching loop is occurring on the switch.

    • Incorrect SNMP settings on the switch.

    • Wrong subnet mask on the switch.

    • Port is misconfigured on the switch.

    Correct Answer
    A. Port is misconfigured on the switch.
    Explanation
    The probable cause for the user being unable to connect to the network while others on the same switch can connect successfully is a misconfiguration of the port on the switch. This means that the specific port that the user is connected to may have incorrect settings or configurations that are preventing a successful connection.

    Which of the following Will allow an administrator to restrict communication between network devices?

    • DHCP

    • NAT

    • CIDR

    • ACL

    Correct Answer
    A. ACL
    Explanation
    ACL stands for Access Control List. It is a security feature that allows an administrator to restrict communication between network devices. ACLs can be used to control network traffic by specifying which packets are allowed to pass through a network interface and which are denied. By configuring ACLs, administrators can define rules and policies to filter and control the flow of data within a network, enhancing security and preventing unauthorized access.

    For an enterprise to use one of the reserved private IP address ranges, as best practice they should coordinate with:

    • Their IT department.

    • IANA.

    • IEEE.

    • Their legal department.

    Correct Answer
    A. Their IT department.
    Explanation
    When an enterprise wants to use one of the reserved private IP address ranges, it is best practice to coordinate with their IT department. The IT department is responsible for managing and maintaining the organization's network infrastructure, including IP address allocation. They have the knowledge and expertise to ensure that the chosen IP address range does not conflict with existing network resources and can provide guidance on best practices for IP address management within the organization. Coordinating with the IT department helps to maintain the integrity and stability of the network.

    At which of the following layers of the OSI model would a repeater operate?

    • Layer 7

    • Layer 5

    • Layer 3

    • Layer 1

    Correct Answer
    A. Layer 1
    Explanation
    A repeater operates at Layer 1 of the OSI model, which is the Physical layer. This layer is responsible for the transmission and reception of raw data bits over a physical medium. A repeater amplifies and regenerates signals that have weakened over long distances, allowing them to be transmitted further without loss of quality. It does not interpret or manipulate the data in any way, making it the appropriate layer for a repeater to operate.

    An organization with 2,500 users has exhausted their Internet bandwidth. After some investigation, the network administrator discovers that 95%of the traffic is coming from web browsing. Which of the following network devices could be added to BEST reduce the amount of Internet bandwidth the company is using?

    • Content switch

    • Load balancer

    • Proxy server

    • An additional DNS server

    Correct Answer
    A. Proxy server
    Explanation
    A proxy server can be added to the network to reduce the amount of Internet bandwidth being used. A proxy server acts as an intermediary between the users and the Internet. It can cache frequently accessed web pages and files, reducing the need for multiple users to download the same content from the Internet. This can help to conserve bandwidth and improve network performance. By routing web browsing traffic through the proxy server, the organization can effectively reduce the amount of Internet bandwidth being consumed by web browsing activities.

    Which of the following subnet masks will produce the smallest subnet size for a pointtopoint network link?

    • 255.255.255.248

    • 255.255.255.128

    • 255.255.255.252

    • 255.255.255.0

    Correct Answer
    A. 255.255.255.252
    Explanation
    The subnet mask 255.255.255.252 will produce the smallest subnet size for a point-to-point network link. This is because a subnet mask of 255.255.255.252 allows for only 2 usable IP addresses in the subnet, which is the minimum number required for a point-to-point link. The other subnet masks listed allow for larger subnet sizes and more usable IP addresses.

    Two servers and five workstations are connected using a 100BASE-T network. Which of the following physical topologies is used?

    • FDDI

    • Bus

    • Ring

    • Star

    Correct Answer
    A. Star
    Explanation
    A star topology is used in this scenario where two servers and five workstations are connected using a 100BASE-T network. In a star topology, all devices are connected to a central hub or switch. This central hub acts as a central point of communication, allowing each device to communicate directly with the hub. This topology provides a high level of reliability and scalability as each device has its own dedicated connection to the central hub, minimizing network downtime and allowing for easy addition or removal of devices.

    Which of the following is the point when local exchange carrier responsibility ends?

    • Demarc

    • Point of Presence (POP)

    • Smart jack

    • MDF

    Correct Answer
    A. Demarc
    Explanation
    The point when local exchange carrier responsibility ends is known as the demarcation point. This is the point where the responsibility for the telecommunications line transfers from the service provider to the customer. At the demarcation point, the service provider's responsibility for maintaining and repairing the line ends, and any issues beyond that point are the customer's responsibility.

    A company would like to configure newsfeeds on the network for employees to be aware of internal company information. Which of the following ports would be used to allow newsfeeds to passthrough?

    • 25

    • 22

    • 119

    • 143

    Correct Answer
    A. 119
    Explanation
    Port 119 is used for the Network News Transfer Protocol (NNTP), which is specifically designed for the distribution, retrieval, and posting of news articles. By allowing newsfeeds to pass through port 119, employees will be able to access internal company information and stay updated on the latest news within the organization. Ports 25, 22, and 143 are used for other protocols such as SMTP (email), SSH (secure shell), and IMAP (email retrieval), respectively, and are not relevant for configuring newsfeeds.
