A technician is tasked with providing network-based high availability to a pair of identical web servers.
Which of the following minimum server NIC configurations fulfills these requirements?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
The correct answer to this question is B. One physical NIC per server: each individual NIC configured for network load balancing.
Network-based high availability is a strategy to ensure that critical applications or services are always available to users by eliminating single points of failure in the network. In this scenario, a pair of identical web servers needs to be configured to provide high availability.
Option A, which suggests configuring one NIC for multicast and one for broadcast, is not a viable solution for high availability. Multicast and broadcast are not reliable methods for load balancing, and they do not guarantee high availability in the event of a network failure.
Option C, which suggests configuring one NIC for network traffic and one for web traffic, may improve network performance, but it does not provide high availability. In fact, separating network and web traffic may increase the risk of a single point of failure.
Option D, which suggests configuring each NIC with the same MAC and IP address, is not a feasible solution. Configuring identical MAC addresses and IP addresses on multiple network interfaces will create an IP conflict, which will result in network connectivity issues.
Option B, which suggests configuring each individual NIC for network load balancing, is the correct answer. Network Load Balancing (NLB) is a clustering technology that distributes incoming network traffic across multiple servers to provide high availability and scalability. NLB is designed to eliminate single points of failure in the network and ensure that traffic is always directed to an available server. In this scenario, each web server should have a single physical NIC configured for NLB to provide network-based high availability.
