Switch stacking is a technology that allows multiple physical switches to be interconnected and managed as a single logical switch. The main benefits of switch stacking are scalability, manageability, and improved performance. Let's discuss each of the given options and which one is the correct answer.

A. It provides redundancy with no impact on resource usage: Switch stacking provides redundancy by allowing multiple switches to work together as a single logical unit. If one switch in the stack fails, the other switches can take over its functions without affecting the network's operation. This provides high availability and ensures that the network is always up and running. However, switch stacking does impact resource usage since multiple switches are now working as one logical unit, which can lead to increased power consumption and higher management overhead.

B. It simplifies adding and removing hosts: Switch stacking simplifies adding and removing hosts by allowing network administrators to manage all the switches in the stack as a single entity. This makes it easier to configure, manage, and troubleshoot the network. When a new host is added, it can be easily connected to any switch in the stack, and the switch stack will automatically distribute the traffic across all the switches. Similarly, when a host is removed, the switch stack will adjust the traffic flow accordingly.

C. It supports better performance of high-needs applications: Switch stacking can improve the performance of high-needs applications by increasing the available bandwidth and reducing network congestion. With switch stacking, multiple switches can be combined to create a single logical unit with more ports and higher bandwidth. This allows for more devices to be connected to the network, and data can be transmitted more quickly and efficiently. However, switch stacking does not guarantee better performance of high-needs applications, as other factors such as network topology, traffic patterns, and equipment quality also play a role.

D. It provides higher port density with better resource usage: Switch stacking provides higher port density by allowing multiple switches to work together as a single logical unit. This means that the total number of available ports is increased, making it easier to connect more devices to the network. Additionally, switch stacking can lead to better resource usage by enabling load balancing and link aggregation between the switches in the stack. This ensures that the network is optimized for performance and efficiency.

Based on the given options, the correct answer is D. Switch stacking provides higher port density with better resource usage.
