Exam N10-008 topic 1 question 384 discussion

The correct answer is A. Multipathing. Multipathing allows multiple physical network connections to a server to share a single IP address, providing both increased performance and fault tolerance in the event of a NIC failure. This is commonly used for servers that require high availability and should be operational at all times. Spanning Tree Protocol (B) and First Hop Redundancy Protocol (C) are network protocols used to provide redundancy and failover capabilities for network switches and routers, but they do not apply to servers directly. Elasticity (D) refers to the ability of a system or application to automatically scale up or down to meet changing demands, and is not directly related to server availability or network connectivity.

To improve performance or fault tolerance, concurrent multipath routing (CMR) is often taken to mean simultaneous management and utilization of multiple available paths for the transmission of streams of data. The streams may be emanating from a single application or multiple applications. A stream is assigned a separate path, as uniquely possible given the number of paths available. If there are more streams than available paths, some streams will share paths. CMR provides better utilization of bandwidth by creating multiple transmission queues. It provides a degree of fault tolerance in that should a path fail, only the traffic assigned to that path is affected. There is also, ideally, an alternative path immediately available upon which to continue or restart the interrupted stream.

Multipathing is about SAN and also WiFi but is the right answer here FHRP could use single IP address for multiple routers, a different thing, but could confuse during exams

MULTIPATHING (Used in Storage Area Networks) creates more than one physical path between the server and it's sorage devices for better fault tolerance and performance.
