Net+ DAY 5 and 6 Wireless Networking Cloud Concepts and Virtuali

A company is deploying a new wireless network in a high-density office environment. Which of the following wireless standards would be MOST appropriate to optimize data transfer speeds and minimize interference?

• 802.11g
• 802.11n
• 802.11ac
• 802.11ax

Answer explanation

802.11ac offers higher data rates and utilizes multiple streams compared to older standards, improving performance in congested environments.

A user is experiencing slow and unreliable wireless connectivity at home. They suspect interference from neighboring networks. Which of the following tools can be used to identify the best wireless channel for their access point?

• Ping utility
• Traceroute
• Wireless network scanner
• Web browser

Answer explanation

A wireless network scanner can identify nearby networks and their channels, allowing selection of a less congested channel for optimal performance.

A technician is troubleshooting a wireless network where multiple users are reporting dropped connections. What is the MOST likely cause of this issue?

• Incorrect SSID configuration
• Outdated wireless drivers
• Low signal strength
• Faulty access point

Answer explanation

Weak signal strength can lead to dropped connections. Check for proper access point placement and potential interference sources.

A company is implementing a guest wireless network. Which of the following security protocols would be MOST appropriate for this scenario, balancing security and ease of access?

• WPA3
• WPA2-PSK (AES)
• WEP
• Open

Answer explanation

WPA2-PSK (AES) offers a good balance of security and ease of use with a pre-shared key for guest access.

A user is unable to connect to a secure wireless network. They have verified the SSID and password are correct. What could be the reason for this issue?

• Incorrect IP address
• Disabled wireless adapter
• Incompatible encryption type
• Firewall blocking access

Answer explanation

The user's device might not support the encryption type used by the access point. Check the supported encryption types on both devices.

A user is having trouble connecting to a 5 GHz wireless network on their laptop. The laptop supports both 2.4 GHz and 5 GHz bands. What could be the cause of this issue?

• Outdated network adapter
• Incorrect router settings
• Disabled 5 GHz band on the laptop

Answer explanation

The user might need to enable the 5 GHz band in their laptop's wireless adapter settings.

A company wants to improve the security of their wireless network. Which of the following actions would be MOST effective?

• Hiding the SSID
• Using a strong WPA2-PSK
• Enabling WPS
• Disabling guest access

Answer explanation

While hiding the SSID offers some obscurity, a strong WPA2-PSK with a complex password provides a more robust security layer.

A technician is configuring a wireless network for a large open office space. Which of the following antenna types would be MOST suitable for this environment?

• Directional antenna
• High-gain antenna
• Omnidirectional antenna

Answer explanation

Omnidirectional antennas provide 360-degree coverage, making them ideal for open spaces where signal needs to reach devices in all directions.

You are troubleshooting a wireless network where some devices connect successfully while others fail. What could be the cause of this issue?

• Incorrect subnet mask
• Faulty access point firmware
• Outdated wireless drivers on some devices

Answer explanation

Outdated wireless drivers can lead to compatibility issues and connection problems. Update the drivers on

A technician notices a significant decrease in wireless network performance during peak usage hours. What technology can be used to manage bandwidth allocation and prioritize critical traffic?

• Quality of Service (QoS)
• VLANs
• Port security
• Access control lists (ACLs)

Answer explanation

QoS allows prioritizing specific types of traffic, ensuring critical applications maintain performance during peak usage.
