    • Equipments Life Circle

    • Equipment Life Records

    • Equipment Life Documents

    Correct Answer
    A. Equipments Life Cycle
    Explanation
    The correct answer is "Equipments Life Cycle". In CIPS, documents generated are considered historical documentation. These records will remain associated with the equipment throughout its life cycle. This means that the records will be maintained from the time the equipment is acquired or installed until it is retired or disposed of. The equipment life cycle includes various stages such as procurement, operation, maintenance, and retirement. Keeping records associated with the equipment throughout its life cycle helps in tracking its history, performance, and any necessary maintenance or repairs.

    207. Which specification allows for unique identification at the data link layer?

    • MAC sublayer

    • DATA sublayer

    • LOGIC sublayer

    • ROM sublayer

    Correct Answer
    A. MAC sublayer
    Explanation
    The MAC (Media Access Control) sublayer allows for unique identification at the data link layer. This sublayer is responsible for controlling access to the physical medium and assigning unique MAC addresses to network devices. By using MAC addresses, devices can be identified and communicate with each other on a local network. The MAC sublayer ensures that data is transmitted and received correctly between devices, preventing collisions and ensuring efficient data transmission.

    210. What are the two classifications of transport protocols? 

    • Connection and Connectionless oriented

    • Power and Powerless oriented

    • Active and Reactive oriented

    • Secured and Unsecured oriented

    Correct Answer
    A. Connection and Connectionless oriented
    Explanation
    The two classifications of transport protocols are connection-oriented and connectionless-oriented. Connection-oriented protocols establish a dedicated communication path between the sender and receiver before data transmission, ensuring reliable delivery and error detection. Examples of connection-oriented protocols include TCP (Transmission Control Protocol). On the other hand, connectionless-oriented protocols do not establish a dedicated path and do not guarantee reliable delivery. They simply send data packets independently, without any acknowledgment or error checking. UDP (User Datagram Protocol) is an example of a connectionless-oriented protocol.

    211. What are the two methods of subnet masking? 

    • Classful and Classless

    • Classified and Declassified

    • Glasses and Glassless

    • Careful and Careless

    Correct Answer
    A. Classful and Classless
    Explanation
    The correct answer is Classful and Classless. Subnet masking is a technique used in computer networking to divide an IP address into two parts: the network address and the host address. Classful subnet masking is an older method that divides IP addresses into classes (A, B, C, etc.) and assigns a default subnet mask based on the class. Classless subnet masking, on the other hand, allows for more flexibility by allowing the subnet mask to be of any length, not just the default values assigned by classful subnet masking.

    216. What is the name for networks that use the same software and protocols as the public internet, but exist as a portion of an entities private network? 

    • Intranet

    • Extranet

    • Outernet

    • Innernet

    Correct Answer
    A. Intranet
    Explanation
    An intranet is a private network that uses the same software and protocols as the public internet. It allows an organization to share information and resources among its members, but access is restricted to authorized users within the organization. Unlike the public internet, which is accessible to anyone, an intranet is only accessible within the organization's network.

    Correct Answer
    A. JWICS
    Explanation
    JWICS stands for Joint Worldwide Intelligence Communications System. It is a secure network that provides a transmission path capable of secure video/data within the defense intelligence community. JWICS is used by various agencies and organizations within the defense intelligence community to securely communicate and share sensitive information. It ensures that the information transmitted is protected from unauthorized access and maintains the confidentiality, integrity, and availability of the data.
