A network contains 25 access points. Which of the following devices would be best to change configurations on all the devices remotely?

Correct Answer:A
A WLAN controller is a device that can centrally manage and configure multiple access points in a wireless network. A WLAN controller can change settings on all the devices remotely, such as SSIDs, security policies, firmware updates, and channel assignments. A WLAN controller can also monitor the performance and status of the access points and provide load balancing and fault tolerance

A network technician crimped a length of IJTP with TIAElA-568A on one end and TINE-IA- 5688 on the other. Which of the following cable types did the technician create?

Correct Answer:A
The cable type that the technician created is a crossover cable. A crossover cable is a type of twisted-pair cable that has the transmit and receive pairs reversed on one end. A crossover cable is used to connect two devices of the same type, such as two switches or two computers, without using a hub or a switch. A crossover cable can be made by crimping one end of the cable with TIA/EIA-568A standard and the other end with TIA/EIA- 568B standard, or vice versa. These standards define the color coding and pin
assignments for RJ-45 connectors on twisted-pair cables. References: CompTIA Network+ N10-008 Certification Study Guide, page 53; The Official CompTIA Network+ Student Guide (Exam N10-008), page 2-4.

A network technician needs to install patch cords from the UTP patch panel to the access switch for a newly occupied set of offices. The patch panel is not labeled for easy jack identification. Which of the following tools provides the easiest way to identify the appropriate patch panel port?

Correct Answer:A
A toner is a tool that generates an audible signal that can be traced by a probe. A network technician can use a toner to identify the appropriate patch panel port by connecting the toner to one end of the patch cord and using the probe to scan the patch panel until the signal is detected. A toner is the easiest way to identify the patch panel port when the patch panel is not labeled, as it does not require a laptop, a cable tester, or a visual fault locator.
A toner can also be used to locate breaks or shorts in a cable, or to verify continuity. References:

A network administrator is setting up several loT devices on a new VLAN and wants to accomplish the following
* 1. Reduce manual configuration on each system
* 2. Assign a specific IP address to each system
* 3. Allow devices to move to different switchports on the same VLAN
Which of the following should the network administrator do to accomplish these requirements?

Correct Answer:A
A reservation is a feature of DHCP that assigns a specific IP address to a device based on its MAC address. This way, the device will always receive the same IP address from the DHCP server, regardless of its location or connection time. A network administrator can set up a reservation for each loT device to accomplish the requirements of reducing manual configuration, assigning a specific IP address, and allowing devices to move to different switchports on the same VLAN.

A technician is troubleshooting a previously encountered issue. Which of the following should the technician reference to find what solution was implemented to resolve the issue?

Correct Answer:D
Change management documentation is a record of the changes that have been made to a system or process, including the reason, date, time, and impact of each change. A technician can reference this documentation to find what solution was implemented to resolve a previously encountered issue, as well as any potential side effects or dependencies of the change.
