    • CSMA/CD

    • CSMA/CA

    • Token passing

    • Polling

    Correct Answer
    A. CSMA/CA
    Explanation
    Wireless networks use the CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism to access the network. This mechanism allows devices to listen for ongoing transmissions before sending their own data, thus avoiding collisions. CSMA/CA involves a device sending a request to transmit, and if the channel is clear, it can proceed with transmitting data. If the channel is busy, the device waits for a random amount of time before attempting again. This collision avoidance method is crucial in wireless networks where multiple devices share the same channel.

    • Reduce the number of broadcast domains.

    • Reduce the number of nodes in a broadcast domain.

    • Increase the number of available Media Access Control (MAC) addresses.

    • Increase the number of available IP addresses.

    • Reduce the number of available IP addresses.

    Correct Answer
    A. Reduce the number of nodes in a broadcast domain.
    Explanation
    Incorporating VLANs in a network helps to reduce the number of nodes in a broadcast domain. A broadcast domain is a network segment where broadcast packets are forwarded to all devices. By dividing the network into VLANs, broadcast traffic is contained within each VLAN, reducing the number of devices that receive the broadcast packets. This improves network efficiency and reduces congestion caused by excessive broadcast traffic.

    What is the minimum cabling requirement for a 100BaseTx network?

    • Category 3 UTP cable

    • Category 5 UTP cable

    • Category 6 UTP cable

    • Multimode fiber cable

    • Monomode fiber cable

    Correct Answer
    A. Category 5 UTP cable
    Explanation
    The minimum cabling requirement for a 100BaseTx network is Category 5 UTP cable. This type of cable is capable of supporting data transmission speeds of up to 100 Mbps, which is the requirement for a 100BaseTx network. Category 3 UTP cable is not sufficient as it can only support speeds up to 10 Mbps. Category 6 UTP cable is capable of supporting higher speeds, but it is not necessary for a 100BaseTx network. Multimode and monomode fiber cables are typically used for longer distance and higher speed networks, and are not the minimum requirement for a 100BaseTx network.

    A router’s static route is set by the:

    • Next upstream router.

    • Routing protocol.

    • Network administrator.

    • Adjacent network.

    • Database Administrator

    Correct Answer
    A. Network administrator.
    Explanation
    A router's static route is set by the network administrator. The network administrator is responsible for configuring and managing the network infrastructure, including routers. Static routes are manually configured routes that are entered into the router's routing table. This allows the network administrator to control the path that network traffic takes by specifying the next hop or destination for specific IP addresses or network ranges. The network administrator determines the static routes based on the network topology and requirements, ensuring efficient and secure routing within the network.

    What type of record does DNS use to find a mail service?

    • Host (A) DNS record

    • Host (AAAA) DNS record

    • Canonical (CNAME) DNS record

    • Mail Exchanger (MX) DNS record

    • Service (SRV) DNS record

    Correct Answer
    A. Mail Exchanger (MX) DNS record
    Explanation
    DNS uses the Mail Exchanger (MX) DNS record to find a mail service. This record specifies the mail server responsible for accepting email messages on behalf of a domain. When someone sends an email to a specific domain, the MX record is used to determine which server should receive the email.

    How many bits are there in an Internet Protocol version 6 (IPv6) address?

    • 32

    • 64

    • 128

    • 256

    • 512

    Correct Answer
    A. 128
    Explanation
    An Internet Protocol version 6 (IPv6) address consists of 128 bits. This is a significant increase compared to the previous version, IPv4, which had only 32 bits. The increased number of bits allows for a much larger address space, accommodating the growing number of devices connected to the internet. The 128-bit address format provides a virtually unlimited number of unique addresses, ensuring the continued growth and expansion of the internet.

    In which OSI layer does routing occur?

    • Physical

    • Data Link

    • Network

    • Presentation

    • Application

    Correct Answer
    A. Network
    Explanation
    Routing occurs in the Network layer of the OSI model. This layer is responsible for the logical addressing and routing of data packets between different networks. It determines the optimal path for data transmission, based on network conditions and routing protocols, to ensure that data reaches its intended destination efficiently. The Network layer also handles the fragmentation and reassembly of data packets, as well as the error handling and congestion control mechanisms.

    The query protocol used to locate resources on a network is:

    • Tracert

    • Telnet

    • Lightweight Directory Access Protocol (LDAP)

    • User Datagram Protocol (UDP)

    • Transport Controll Protocol

    Correct Answer
    A. Lightweight Directory Access Protocol (LDAP)
    Explanation
    LDAP is a query protocol used to locate resources on a network. It is specifically designed for accessing and maintaining directory services over a TCP/IP network. LDAP allows clients to search, retrieve, and update information in a directory server. It is widely used in various applications, such as user authentication, email systems, and address book services. Tracert, Telnet, UDP, and TCP are not query protocols used for locating resources on a network.
