A network engineer recently deployed a new application server in a cloud environment. Which of the following should be implemented to prevent a single point of failure within the system?

The correct answer is C. High availability. High availability (HA) is a system design approach that uses redundancy, failover clustering, and load balancing to ensure a system remains operational if one component fails, directly eliminating a single point of failure. Rapid elasticity (A) is about dynamic resource…

Explanation

High availability (HA) is a system design approach that uses redundancy, failover clustering, and load balancing to ensure a system remains operational if one component fails, directly eliminating a single point of failure. Rapid elasticity (A) is about dynamic resource scaling, not redundancy. RAID (B) provides storage redundancy for disk drives but does not address server-level single points of failure. Shared resources (D) refers to cloud resource pooling, not fault tolerance.
