Employees report intermittent Wi-Fi disconnections and slow speeds. A network scan shows an unknown access point with the same SSID as the company network but on a different channel. What is the most likely issue?

The company AP is overloaded with too many clients

The clients are using outdated wireless drivers

The Wi-Fi channel is congested due to neighboring networks

A rogue access point is causing a denial of service

A company wants to provide Wi-Fi to guests in their lobby. They want to prevent guests from accessing internal resources while still allowing internet access. What is the best approach?

Use the same SSID as the internal network but with a different passphrase

Create a separate guest SSID with a captive portal and VLAN isolation

Disable SSID broadcasting for the guest network

Use WPA2-Enterprise for guests with a shared account

A company is deploying Wi-Fi in a high-security facility. They need to prevent attackers from capturing and cracking the pre-shared key. They also want to support older devices that do not support WPA3. What is the best configuration?

Use WPA2-Personal with a very long passphrase

Use WPA2-Enterprise with 802.1X and certificates

Use WPA3-Personal with a strong passphrase
