Which network security control is designed to detect and alert on suspicious activity but does not actively block traffic?

Intrusion Prevention System (IPS)

Intrusion Detection System (IDS)

A network administrator is troubleshooting a connectivity issue. A workstation can ping the default gateway but cannot reach a server on a different subnet. The administrator checks the routing table and sees that there is no route to the server's subnet. What is the MOST likely cause?

Missing or incorrect route on the router

Incorrect subnet mask on the workstation

A security analyst notices a sudden spike in outbound traffic from a single workstation to an external IP address on port 443. The workstation is not a web server. Which tool should the analyst use to investigate the source of this traffic?

Packet sniffer (e.g., Wireshark)

A small business wants to secure its office Wi-Fi network. They have legacy devices that do not support WPA3. What is the best security configuration to maximize protection while maintaining compatibility?

Use WPA3-only mode and require all legacy devices to upgrade.

Use WEP with MAC address filtering.

Use WPA2-AES with a strong passphrase and disable WPS.

Use WPA2-TKIP for maximum compatibility.
