    • Any method such as tearing, burning, or shredding; as longs personal data is not recognizable and beyond reconstruction.

    Correct Answer
    A. Any method such as tearing, burning, or shredding; as longs personal data is not recognizable and beyond reconstruction.
    Explanation
    The proper way to destroy records to prevent compromise is by using any method such as tearing, burning, or shredding, as long as personal data is not recognizable and beyond reconstruction. This ensures that the information contained in the records cannot be accessed or used by unauthorized individuals. Placing the records in approved staging containers and shipping them to Federal records centers are also valid methods for secure destruction, but the most important aspect is to ensure that the personal data is completely destroyed and cannot be reconstructed.

    What is a formal set of rules and conventions that govern how computers exchange information over a network medium?

    • Specification

    • Standard

    • Etiquette

    • Protocol

    Correct Answer
    A. Protocol
    Explanation
    A protocol is a formal set of rules and conventions that govern how computers exchange information over a network medium. It defines the format, timing, sequencing, and error control of data transmission. Protocols ensure that devices can communicate effectively and understand each other's messages. They provide a standardized way for computers to interact and exchange data, enabling seamless communication across different network devices and platforms.

    What topology defines the way in which devices communicate, and data is transmitted, throughout the network?

    • Physical

    • Logical

    • Star

    • Hybrid

    Correct Answer
    A. Logical
    Explanation
    Logical topology refers to the way devices are connected and communicate with each other in a network. It defines the paths that data takes from one device to another, regardless of the physical layout of the network. This includes the arrangement of nodes, the flow of data, and the protocols used for communication. Unlike physical topology, which focuses on the physical connections between devices, logical topology focuses on the logical relationships and connections between devices.

    What type of network makes use of tunneling and security protocols to enables a group of two or more computer systems to communicate over the public Internet?

    • Local Area Network

    • Wide Area Network

    • Virtual Private Network

    • Metropolitan Area Network

    Correct Answer
    A. Virtual Private Network
    Explanation
    A Virtual Private Network (VPN) is a type of network that uses tunneling and security protocols to enable communication between two or more computer systems over the public Internet. It creates a secure and private connection, allowing users to access resources and share data as if they were directly connected to a private network, even though they are physically located in different locations. VPNs are commonly used by businesses and individuals to ensure the confidentiality and integrity of their data while using public networks.

    Using a range of 1-26 is the first octet of an IPv4 address, what class does it belong to?

    • Class A

    • Class B

    • Class C

    • Class D

    Correct Answer
    A. Class A
    Explanation
    An IPv4 address is divided into different classes based on the range of the first octet. Class A addresses have a range of 1-126, which means that if the first octet of an IPv4 address falls within this range, it belongs to Class A. Therefore, the correct answer is Class A.

  • 45. 

    What IPv4 reserved address is used for loop back?

    • 0.0.0.0

    • 127.0.0.1

    • 207.55.157.255

    • 255.255.255.255

    Correct Answer
    A. 127.0.0.1
    Explanation
    The IPv4 reserved address used for loop back is 127.0.0.1. This address is commonly referred to as the loopback address and is used to test network connectivity on a local machine. When a packet is sent to this address, it is immediately looped back and delivered to the sending host, allowing for testing and troubleshooting of network applications without the need for an external network connection.

    Which landline transmission medium is the primary carrier of voice communications?

    • Twisted pair cable

    • Fiber optic cable

    • Coaxial cable

    • Twinax cable

    Correct Answer
    A. Twisted pair cable
    Explanation
    Twisted pair cable is the primary carrier of voice communications because it is a widely used and cost-effective transmission medium for telephone systems. It consists of two insulated copper wires twisted together, which helps to reduce interference and crosstalk. Twisted pair cable is capable of carrying analog voice signals efficiently over short to medium distances, making it the preferred choice for landline telephone networks.

    Which of the following is not the four security threats to Wireless Local Area Network?

    • Rogue Access Point

    • Direct Connections

    • War Drivers

    • Hackers

    Correct Answer
    A. Direct Connections
    Explanation
    Direct Connections is not considered one of the four security threats to Wireless Local Area Network. Rogue Access Point refers to unauthorized access points that can be used to gain unauthorized access to the network. War Drivers are individuals who drive around with a wireless device to detect and exploit vulnerabilities in wireless networks. Hackers are individuals who attempt to gain unauthorized access to the network. However, Direct Connections does not specifically pose a security threat to the Wireless Local Area Network.

    What rule establishes the percent of data that should be local to a segment and the percentage of data that should be destined to traverse a bridge to the other segment?

    • 90/10 rule

    • 80/20 rule

    • 70/30 rule

    • 60/40 rule

    Correct Answer
    A. 80/20 rule
    Explanation
    The 80/20 rule establishes that 80% of the data should be local to a segment, meaning it stays within that segment, while 20% of the data should be destined to traverse a bridge to the other segment. This rule helps in determining the distribution of data between segments and ensures efficient communication and data sharing between them.

    What is the method called when the entire frame is received and placed into the buffer, an error check is performed, and the frame is sent to the proper port for delivery?

    • Store-and-forward

    • Cross-over

    • Fragment-free

    • Adaptive

    Correct Answer
    A. Store-and-forward
    Explanation
    Store-and-forward is the method in which the entire frame is received and stored in the buffer. An error check is then performed to ensure the integrity of the frame. Once the error check is successful, the frame is sent to the appropriate port for delivery. This method ensures that the entire frame is received and checked for errors before forwarding it, which helps in preventing the transmission of corrupt or incomplete data.
