CompTIA Cloud+ (CV1-003) — Question 2

A systems administrator for an e-commerce company will be migrating the company's main website to a cloud provider. The principal requirement is that the website must be highly available.
Which of the following will BEST address this requirement?

Answer options

Correct answer: A

Explanation

Vertical scaling allows resources to be increased on a single server, enabling it to handle more traffic and improving availability. A server cluster, while also useful for high availability, typically involves multiple servers working together, which may not address the requirement as directly as vertical scaling. Redundant switches and next-generation firewalls are important for network reliability and security, but they do not directly enhance the website's availability.
