An organization's large e-commerce website requires high availability and cannot have degraded performance. Which of the following should a cloud administrator do to best meet the requirements?

The correct answer is A. Create a secondary server and load balance the traffic. High availability requires redundancy - if one server fails, another takes over - and load balancing distributes traffic to prevent performance degradation under load. Creating a secondary server with a load balancer directly addresses both requirements. Upgrading to SSD…

Explanation

High availability requires redundancy - if one server fails, another takes over - and load balancing distributes traffic to prevent performance degradation under load. Creating a secondary server with a load balancer directly addresses both requirements. Upgrading to SSD (Option B) improves I/O performance on a single server but provides no redundancy. Adding a secondary NIC with teaming (Option C) adds network redundancy only, not server-level HA. Changing CPU type and RAM (Option D) is vertical scaling on a single server, which still creates a single point of failure and doesn't address availability.
