The feature that distinguishes a LAN from a WAN is that (D) "a LAN connects computers in a single location".

A LAN (Local Area Network) is a computer network that connects devices in a small geographical area, such as a home, office, or building. In contrast, a WAN (Wide Area Network) is a network that covers a larger geographical area, such as a city, country, or even the whole world. The main difference between the two is the size of the area they cover and the number of devices they connect. LANs typically have higher bandwidth and faster data transfer rates, while WANs often have lower bandwidth and slower transfer rates due to the distance between devices. Both LANs and WANs can be used to share resources and data, but they are designed to meet different needs.

Therefore, the correct answer is (D) "A LAN connects computers in a single location."

The two security measures that would BEST secure a wireless network, according to the given scenario, are:A. Change the encryption method to WPA.D. Enable and configure MAC filtering because WEP (Wired Equivalent Privacy) is the weakest encryption method of the three (WEP, WPA, WPA2) used for securing a wireless network. So, it is best to replace it with WPA (Wi-Fi Protected Access) or WPA2.

Changing the encryption method to WPA will help to prevent unauthorized connections from accessing the wireless network. The third option, enabling SSID broadcast, will not help in securing the wireless network as it will make the network visible to all devices within the range. So, this option is incorrect.

Now coming to option B, limiting the DHCP scope to three addresses total would mean that the router will only provide three IP addresses, making it difficult to add more devices to the network. This method will only create an inconvenience and will not be useful for securing the network. Therefore, this option is also incorrect.

Now coming to option D, enabling and configuring MAC filtering will prevent unauthorized devices from accessing the network by using the device's MAC address to filter out any device that does not have an authorized MAC address. This is one of the effective security measures to secure a wireless network. So, it is one of the right answers.

Finally, option E, changing the broadcast channel to a less commonly used channel, might help reduce the interference from neighboring networks, but it will not prevent unauthorized access to the network. So, this option is also incorrect.

The most pressing security risk in this scenario is (d) Confidentiality.

USB- A USB, or universal serial bus, is a type of hardware interface used to connect devices to computers. USB technology simplifies the process of connecting peripherals to computers by replacing a range of incompatible connectors with a single standardized plug and socket.

Security- Security is a procedure or system that is put in place to safeguard an organization, business, or individual from theft, destruction, or unauthorized access. Security is a set of measures and protocols that are designed to protect and secure an individual, organization, or business from harm, damage, or loss, as well as to provide a safe and secure environment for workers and customers. Security involves the use of technology, software, and hardware to secure digital and physical assets. Confidentiality, integrity, and availability are three principles of security.

Confidentiality- Confidentiality is the practice of keeping sensitive data, information, or communications private and secure. Confidentiality is critical in any business or organization, particularly when it comes to sensitive financial or personnel information. Confidentiality is one of the three cornerstones of security, and it helps to ensure that private information remains private.

In the scenario provided, a user copies files from her desktop computer to a USB flash drive and puts the drive in her pocket. The most pressing security risk is Confidentiality. Since the USB device is portable, it's simple for it to be lost, misplaced, or stolen, allowing any confidential data on it to be viewed by anyone who finds it. As a result, keeping sensitive information safe is critical.

The most distinguishing feature of the use of a client-server processing model over an old mainframe configuration is the distribution of computing power.

A client-server processing model is a distributed application structure that partitions tasks or workload between service providers and service requesters, called clients. Each computer in the client-server model operates as either a client or a server. The server provides services to the clients, such as data sharing, data manipulation, and data storage.

The client requests services from the server, allowing for the distribution of processing responsibilities between the two entities. In this model, the server is responsible for storing data, while the client is responsible for data retrieval. A mainframe configuration is an older computing model that is centralized, where the mainframe performs all computing activities.

All users are linked to the mainframe, which stores all data and applications, as well as handles all processing responsibilities. Mainframes can handle a large amount of data and have a lot of processing power, but they are inflexible and can be difficult to scale. The distribution of computing power is the most distinguishing feature of the use of a client-server processing model over an old mainframe configuration.

The 100BASE-SX and 100BASE-FX standards are designed for slower data transmission rates of 100 Mbps and operate over multimode fiber (MMF) cables with shorter transmission distances, making them unsuitable for this scenario.

The 1000BASE-SX standard also operates over MMF cables, which may not be able to support the necessary distance of 2000 m. Therefore, 1000BASE-LX is the most appropriate standard for this Ethernet network segment setup.

Opening NAT type for multiple PCs requires you to create a static IP address and forwarding ports on your router. This will allow the router to allocate a specific IP address to each device that will always be the same.

Opening NAT type for multiple PC's- To open NAT type for multiple PCs, follow the steps below:

Step 1: Get the MAC addresses of all PCs. Ensure that you have the MAC addresses of all the devices that you want to connect to the network. The MAC address is the unique address that identifies each device on the network. To find the MAC address on a PC, open the command prompt and type "ipconfig/all"

Step 2: Reserve an IP address for each device. Once you have the MAC addresses, you can reserve an IP address for each device. This ensures that each device will always have the same IP address. You can do this by logging into your router and creating a static IP address.

Step 3: Port forwarding. Once you have created static IP addresses, you will need to forward the ports for each device. This involves opening the required ports for each device on your router. This can be done by accessing your router settings and forwarding the required ports. To do this, you will need to know which ports to forward for each device.

The term which best describes the KPI that Homer is revising at his company is RTO because it is a metric used to define the amount of time within which services must be restored after a failure.

RTO stands for Recovery Time Objective. In a disaster recovery strategy, RTO is a critical component for determining how long an enterprise can operate without critical systems before experiencing unacceptable losses.An RTO determines how long an organization's business processes and operations can survive before a service interruption or application outage occurs.

The RTO is based on the criticality of the business process, system availability requirements, and the company's overall business continuity policy. Thus, the Recovery Time Objective is the maximum tolerable length of time that a computer, system, network, or application can be down following a failure before the loss of organization or system functionality has unacceptable consequences.

MTBF, or Mean Time Between Failures, is a statistical measure of the average time a product or system will perform satisfactorily. This measure is widely used in the manufacturing and engineering industries to determine the reliability of a product or system.

MTRR, or Memory Type Range Registers, is a CPU feature that specifies how system memory can be accessed. RPO, or Recovery Point Objective, is a metric used to define the maximum amount of time that an organization's processes or data can be lost following a service interruption or disaster. An RPO determines the amount of data loss an organization can tolerate before experiencing unacceptable business impacts or consequences.
