What is the primary function of an intrusion prevention system (IPS)?

To monitor network traffic in real time and block malicious activity

To encrypt all network traffic to ensure confidentiality

To detect and report security incidents without taking action

To filter traffic based on MAC addresses

What is the primary role of a router in a network?

To forward frames within a LAN based on MAC addresses

To forward packets between different networks based on IP addresses and routing tables

To provide wireless connectivity to clients and bridge them to the wired network

To inspect application-layer traffic and block malicious activity

An organization has deployed a firewall but wants to add a device that can actively detect and block malicious traffic in real time by analyzing network traffic patterns. Which component should be added to the network?

An intrusion prevention system (IPS)

A warehouse is installing IP cameras and wireless access points in areas without nearby power outlets. The network switch is PoE-enabled. What is the most efficient way to power these devices?

Connect them to the PoE switch using standard Ethernet cabling.

Use wireless power transfer to charge the devices.

Use power adapters for each device and run extension cords.

Install a separate power-over-Ethernet injector for each device.

A small office has a single Layer 2 switch connecting 20 PCs and a server. The PCs are all in the same IP subnet. Users report that they can reach the server but cannot reach the internet. The router that provides internet access is connected to the switch. What is the most likely reason for this issue?

The PCs have a default gateway configured that is not the router's IP address.

The switch is not performing inter-VLAN routing.

The server is acting as a router and blocking internet traffic.

The router is not receiving frames destined for the internet because the switch is not forwarding them based on MAC addresses.
