A local service provider connected 20 schools in a large city with a fiber-optic switched network. Which of the following network types did the provider set up?

Correct Answer:B
MAN stands for Metropolitan Area Network, and it is a type of network that covers a large geographic area, such as a city or a county. MANs are often used to connect multiple LANs (Local Area Networks) within a region, such as schools, offices, or government buildings. MANs typically use high-speed and high-capacity transmission media, such as fiber-optic cables, to provide fast and reliable data communication. MANs can also provide access to WANs (Wide Area Networks), such as the Internet, or other services, such as cable TV or VoIP.
The other options are not correct because they are not the type of network that covers a large city. They are:
✑ LAN. LAN stands for Local Area Network, and it is a type of network that covers a
small geographic area, such as a home, an office, or a building. LANs are often used to connect multiple devices, such as computers, printers, or phones, within a single network. LANs typically use low-cost and low-capacity transmission media, such as twisted-pair cables, to provide data communication. LANs can also provide access to other networks, such as MANs or WANs, through routers or gateways.
✑ CAN. CAN stands for Campus Area Network, and it is a type of network that
covers a moderate geographic area, such as a university, a hospital, or a military base. CANs are often used to connect multiple LANs within a campus, such as different departments, buildings, or facilities. CANs typically use medium-cost and medium-capacity transmission media, such as coaxial cables, to provide data communication. CANs can also provide access to other networks, such as MANs or WANs, through routers or gateways.
✑ WAN. WAN stands for Wide Area Network, and it is a type of network that covers
a very large geographic area, such as a country, a continent, or the world. WANs are often used to connect multiple MANs or LANs across different regions, such as
different cities, states, or countries. WANs typically use high-cost and high- capacity transmission media, such as satellite links, to provide data communication. WANs can also provide access to various services, such as the Internet, email, or VPN.

A customer has an attached USB printer that needs to be shared with other users. The desktop team set up printer sharing. Now, the network technician needs to obtain the necessary information about the PC and share it with other users so they can connect to the printer. Which of the following commands should the technician use to get the required information? (Select TWO).

Correct Answer:EF
The hostname and ipconfig commands should be used to get the required information about the PC and share it with other users so they can connect to the printer. The hostname command displays the name of the computer on a network. The ipconfig command displays the IP configuration of the computer, including its IP address, subnet mask, default gateway, and DNS servers. These information are necessary for other users to locate and connect to the shared printer on the network. For example, other users can use the UNC path \\hostname\printername or \\ipaddress\printername to access the shared printer.

A branch of a company recently switched to a new ISP. The network engineer was given a new IP range to assign. The ISP assigned 196.26.4.0/26, and the branch gateway router now has the following configurations on the interface that peers to the ISP:

The network engineer observes that all users have lost Internet connectivity. Which of the following describes the issue?

Correct Answer:C
The IP address configured on the router interface is 196.26.4.1/26, which belongs to the IP range assigned by the ISP (196.26.4.0/26). However, this IP address is not valid for this interface because it is the network address of the subnet, which cannot be assigned to any host device. The network address is the first address of a subnet that identifies the subnet itself. The valid IP addresses for this subnet are from 196.26.4.1 to 196.26.4.62, excluding the network address (196.26.4.0) and the broadcast address (196.26.4.63). The router interface should be configured with a valid IP address within this range to restore Internet connectivity for all users.

A user reports that a crucial fileshare is unreachable following a network upgrade that was completed the night before. A network technician confirms the problem exists. Which of the following
troubleshooting Steps should the network technician perform NEXT?

Correct Answer:A
Establishing a theory of probable cause is the third step in the general troubleshooting process, after identifying the problem and gathering information. Establishing a theory of probable cause involves using the information gathered to formulate one or more possible explanations for the problem and testing them to verify or eliminate them. In this scenario, the network technician has confirmed the problem exists
and should proceed to establish a theory of probable cause based on the information available, such as the network upgrade that was completed the night before. Implementing a solution to fix the problem is the fifth step in the general troubleshooting process, after establishing a plan of action. Implementing a solution involves applying the chosen method or technique to resolve the problem and verifying its effectiveness. In this scenario, the network technician has not established a plan of action yet and should not implement a solution without knowing the cause of the problem.
Creating a plan of action to resolve the problem is the fourth step in the general troubleshooting process, after establishing a theory of probable cause. Creating a plan of action involves selecting the best method or technique to address the problem based on the available resources, constraints, and risks. In this scenario, the network technician has not established a theory of probable cause yet and should not create a plan of action without knowing the cause of the problem.
Documenting the problem and the solution is the seventh and final step in the general troubleshooting process, after implementing preventive measures. Documenting the problem and the solution involves recording the details of the problem, its symptoms, its cause, its solution, and its preventive measures for future reference and improvement. In this scenario, the network technician has not implemented preventive measures yet and should not document the problem and the solution without resolving and preventing it.

A customer wants to segregate the traffic between guests on a hypervisor. Which of the following does a technician need to configure to meet the requirement?

Correct Answer:A
A virtual switch is a software-based switch that connects virtual machines on a hypervisor. A virtual switch can create and manage VLANs, which are logical segments of a network that isolate traffic between different groups of devices. A customer can use virtual switches to segregate the traffic between guests on a hypervisor by creating a separate VLAN for each guest and assigning it to a virtual switch port. References:
