CompTIA Network+ Certification Exam Sample Questions (Q469-Q474):

NEW QUESTION # 469
A network administrator needs to implement routing capabilities in a hypervisor. Which of the following should the administrator most likely implement?

Answer: C


NEW QUESTION # 470
A network administrator's device is experiencing severe Wi-Fi interference within the corporate headquarters causing the device to constantly drop off the network. Which of the following is most likely the cause of the issue?

Answer: C

Explanation:
Reference: CompTIA Network+ Certification Exam Objectives - Wireless Networks section.


NEW QUESTION # 471
A small company has the following IP addressing strategy:
User subnet: 192.168.1.0/24
Voice subnet: 192.168.2.0/24
Server subnet: 192 168.10.0/24
A user is unable to connect to the company fileshare server located at 192.168.10.1. The user's networking configuration is:

Which of the following will most likely correct the issue?

Answer: A

Explanation:
If the user cannot communicate with 192.168.10.1, they might be on a different subnet. Changing the subnet mask to 255.255.255.0 ensures the user and the file server are in the same subnet.


NEW QUESTION # 472
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?

Answer: B

Explanation:
A toner probe, often referred to as a toner and probe kit, is the easiest and most effective tool for identifying individual cables in a bundle, especially in situations where the patch panel is not labeled. The toner sends an audible tone through the cable, and the probe detects the tone at the other end, allowing the technician to quickly identify the correct cable.
* Functionality: The toner generates a tone that travels along the cable. When the probe is placed near the correct cable, it detects the tone and emits a sound.
* Ease of Use: Toner probes are straightforward to use, even in environments with many cables, making
* them ideal for identifying cables in unlabeled patch panels.
* Efficiency: This method is much faster and more reliable than manual tracing, especially in complex setups.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Details tools used for cable identification and troubleshooting.
* Cisco Networking Academy: Provides training on using toner probes and other cable testing tools.
* Network+ Certification All-in-One Exam Guide: Explains the use of different tools for network cable identification and management.


NEW QUESTION # 473
A network administrator needs to assign IP addresses to a newly installed network. They choose 192.168.1.0
/24 as their network address and need to create three subnets with 30 hosts on each subnet. Which of the following is a valid subnet mask that will meet the requirements?

Answer: B

Explanation:
Understanding the Requirements
* Network Address: 192.168.1.0/24
* The /24 notation means a subnet mask of 255.255.255.0, providing 256 total addresses (192.168.1.0-192.168.1.255).
* Usable hosts: 256 - 2 (network and broadcast) = 254.
* Goal: Create3 subnets, each with30 hosts.
* Each subnet needs enough addresses to accommodate 30 hosts, plus 2 reserved addresses (network and broadcast) per subnet.
* Total addresses per subnet = 30 (hosts) + 2 (network/broadcast) =32 addresses.
Subnetting Basics (Networking Fundamentals)
* Subnet Mask: Determines how many bits are borrowed from the host portion to create subnets.
* Original Mask: /24 (255.255.255.0) = 24 network bits, 8 host bits.
* Formulae:
* Number of subnets = 2
