1. Which encryption protocol is recommended for securing modern Wi-Fi networks and replaced the vulnerable WEP and WPA standards?
WPA2 uses AES-CCMP encryption and is the minimum recommended standard; WPA3 adds stronger protections including SAE for resistance to offline dictionary attacks.
2. What is the purpose of PoE (Power over Ethernet)?
PoE (Power over Ethernet) delivers electrical power along with data through standard Ethernet cabling, eliminating the need for separate power supplies for devices like IP phones and wireless access points.
3. A company uses IPsec in tunnel mode. What does tunnel mode do compared to transport mode?
IPsec tunnel mode encapsulates the entire original IP packet (header + payload) within a new IP packet, which is common for VPN gateways.
4. What is the purpose of port scanning in network security assessment?
Port scanning identifies which ports are open and what services are listening on networked devices, helping security professionals and attackers identify potential entry points.
5. A junior network technician makes an error that causes a brief outage. What is the most professionally appropriate response from their senior colleague?
Constructive feedback turns incidents into learning opportunities and builds a stronger, more resilient team culture.
6. Which feature on a managed switch prevents a single port from flooding the network by limiting the number of MAC addresses it learns?
Port security limits the number of MAC addresses allowed on a switch port and can shut down or restrict the port if the limit is exceeded.
