An organization needs a solution that will inspect network traffic, determine security threats using signature-based rules, and block the traffic in real time based on the security assessment. Which of the following network devices will support these requirements?
An Intrusion Prevention System (IPS) is designed to inspect network traffic, identify malicious activity using signature-based rules, and block potentially harmful traffic in real time. This aligns with the requirements stated in the question.
Which of the following describes the differences between switches and hubs?
Switches operate at the data link layer (Layer 2) of the OSI model and make decisions based on MAC addresses. Hubs, on the other hand, operate at the physical layer (Layer 1) and simply repeat the signals they receive to all connected devices without any filtering or decision-making.
A network administrator is adding a new wired loT device to the internal network. The only devices that will be communicating are the HVAC system and the loT device. Which of the following should the network administrator do?
When adding a new wired IoT device that will only communicate with the HVAC system, it is best practice to configure a dedicated VLAN. This isolates the traffic between the IoT device and the HVAC system from the rest of the network, enhancing security and network efficiency.

A packet has a destination address that is located outside of the local network. Which of the following should be used to route this packet out of the local network?
Default Gateway: The default gateway is the IP address of the router that connects the local network to external networks (such as the internet). When a packet's destination address is outside the local network, it is sent to the default gateway for further routing.

Which of the following synchronizes time on all devices within a network?
Network Time Protocol (NTP): NTP is a widely adopted protocol for synchronizing clocks across network devices. It ensures that all devices have accurate and consistent time. NTP uses a hierarchical system of time sources to maintain synchronization.
