    ________ routing requires the most administrative overhead.

    • Static

    • Dynamic

    Correct Answer
    A. Static
    Explanation
    Static routing requires the most administrative overhead because it involves manually configuring and maintaining the routing tables on each router in the network. This requires the network administrator to have detailed knowledge of the network topology and manually update the routing tables whenever there are changes in the network. In contrast, dynamic routing protocols automatically exchange routing information between routers, reducing the administrative overhead as the routers can dynamically update their routing tables based on the information received from neighboring routers.

    Rate this question:

  • 7. 

    A private IP address is only used within a _____?

    • WAN

    • Subnetwork

    • Domain

    • LAN

    Correct Answer
    A. LAN
    Explanation
    A private IP address is only used within a LAN (Local Area Network). A LAN is a network that is confined to a small geographic area, such as a home, office, or building. Private IP addresses are reserved for internal use within a LAN and are not routable over the internet. They are used to identify devices within the network and allow them to communicate with each other. Therefore, a private IP address is not used within a WAN (Wide Area Network), subnetwork, or domain.

    True or False: DNS uses both TCP and UDP.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    DNS (Domain Name System) uses both TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). TCP is used when the size of the DNS response exceeds the maximum limit for a UDP packet, or when the DNS query requires a reliable and ordered delivery. UDP is used for most DNS queries as it is faster and more efficient for simple queries that can fit within a single packet. Therefore, the statement "DNS uses both TCP and UDP" is true.

    True or False: Token Ring uses CSMA/CD.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Token Ring does not use CSMA/CD (Carrier Sense Multiple Access with Collision Detection). Instead, it uses a different access method called Token Passing. In Token Ring, a token is passed around the network, and only the device holding the token is allowed to transmit data. This eliminates the need for collision detection since only one device can transmit at a time. Therefore, the statement that Token Ring uses CSMA/CD is false.

    Rate this question:

    RAID ____ provides disk striping with parity.

    • 0

    • 1

    • 3

    • 5

    Correct Answer
    A. 5
    Explanation
    RAID 5 provides disk striping with parity. In RAID 5, data is striped across multiple disks, with parity information distributed across all the disks. This allows for increased performance and fault tolerance. In the event of a disk failure, the parity information can be used to reconstruct the data on the failed disk. RAID 0 does not provide parity, RAID 1 is mirroring, and RAID 3 uses dedicated parity disk.

    Rate this question:

  • 21. 

    True or False: TCP and UDP offer the same services over Port 21.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    TCP and UDP do not offer the same services over Port 21. Port 21 is specifically reserved for FTP (File Transfer Protocol) services. TCP is a connection-oriented protocol that ensures reliable and ordered delivery of data, making it suitable for applications like FTP that require error-free transmission. UDP, on the other hand, is a connectionless protocol that does not guarantee reliable delivery of data, making it unsuitable for FTP services. Therefore, the correct answer is False.
