A.

Load balancer

B.

Jumbo frames

C.

Clustering

D.

Round robin

E.

TCP offloading.

AC.

The correct answers are A. Load balancer and C. Clustering.

A. Load balancer: A load balancer is a device that distributes network traffic across multiple servers to improve fault tolerance, availability, and performance. It distributes incoming traffic evenly across multiple servers, ensuring that no single server is overloaded. This not only ensures that the workload is evenly distributed, but it also provides a level of redundancy in case one or more servers fail. As a result, a load balancer can improve fault tolerance and availability.

C. Clustering: Clustering is a technique used to group multiple servers together so that they function as a single system. This is typically done to improve fault tolerance, availability, and performance. Clustering involves installing specialized software on each server and configuring them to work together as a single unit. The servers in a cluster share a common set of resources, such as storage and memory, which allows them to handle a higher workload than any single server could handle alone. In addition, if one server in the cluster fails, the other servers can pick up the workload, providing a high level of fault tolerance and availability.

B. Jumbo frames: Jumbo frames are larger-than-standard Ethernet frames that can improve network performance by reducing the overhead associated with transmitting smaller frames. However, they do not provide fault tolerance or availability benefits.

D. Round robin: Round-robin is a load-balancing technique that distributes incoming traffic to multiple servers in a circular order. However, it does not provide fault tolerance or availability benefits.

E. TCP offloading: TCP offloading is a technique used to offload some of the processing of TCP/IP packets from the CPU to a specialized network interface card (NIC). This can improve network performance by reducing the load on the CPU, but it does not provide fault tolerance or availability benefits.
