Which statement best describes the typical trade-off of using the 5 GHz band instead of 2.4 GHz?

A
It usually reaches farther through walls than 2.4 GHz and has fewer channel choices.
B
It generally offers more channel choices and capacity than 2.4 GHz, but its signal often weakens more quickly through walls and distance.
C
It is available only to Wi-Fi 6E clients and access points.
D
It always provides better real-world performance, regardless of signal quality or interference.

A small office has a router that already handles routing and DHCP. What role would a standalone access point most directly add?

A
It replaces the modem and provides the internet connection by itself.
B
It must provide routing, switching, firewall, and DHCP services.
C
It provides Wi-Fi access and usually relies on a router for other network functions.
D
It serves only as a security mode for wireless clients.

A user wants to connect a device over 6 GHz using Wi-Fi 6E. Which compatibility requirement must be met?

A
Only the access point needs to support 6 GHz; any Wi-Fi 6 client can use it.
B
Both the client and access point need to support 6 GHz.
C
The client and access point must use 2.4 GHz because Wi-Fi 6E does not operate in 6 GHz.
D
A 6 GHz-capable client is sufficient even if the access point does not support 6 GHz.

Select all recommended security choices for a home or small-office Wi-Fi network.

A
Use WPA3-Personal when all required devices support it.
B
If WPA3-Personal is not supported by required devices, use WPA2-Personal with AES.
C
Use WEP because it is the most compatible option.
D
Leave the network open so older devices can connect.

A home Wi-Fi network is performing poorly, and nearby networks may be competing for airtime. What is the best first step before changing the channel?

A
Disable encryption so the access point can use the channel more efficiently.
B
Change to a random channel repeatedly until performance seems better.
C
Check channel use and interference with diagnostic tools, then test a less congested channel if appropriate.
D
Add more access points immediately without checking their placement or channel use.

Several devices are connected to the Wi-Fi network, but all report no internet access. Which troubleshooting action is most appropriate?

A
Change the SSID, because a network name controls internet access.
B
Disable encryption on every client.
C
Inspect the router and internet connection, since the issue affects multiple devices.
D
Replace the Wi-Fi drivers on every device before checking shared equipment.

A client detects the intended SSID but cannot join the Wi-Fi network. Select all conditions that could directly prevent it from joining.

A
The client is using the wrong passphrase.
B
The client's supported security mode does not match the access point's security mode.
C
The client does not support the band used by the access point.
D
The internet connection is down, even though the client is trying to join Wi-Fi.
E
Nearby networks are using congested channels.

A home network’s older device cannot use WPA3-Personal. Which setting best preserves security while allowing the device to connect, if it supports that mode?

A
Leave the network open so the device can connect
B
Use WEP because older devices are more likely to support it
C
Use WPA2-Personal with AES and a long, unique passphrase
D
Disable encryption whenever a device has trouble joining
