Compared with self-built servers, which of the following descriptions about the advantages of deploying business on the cloud is wrong?

Question

Options

• ASecurity, with a large number of cloud security experts, security services respond in a timely
• BAvailability, automatic downtime migration, automatic snapshot backup, and convenient data
• CScalability, the opening is very flexible, and the configuration can be upgraded online
• DCost, low usage cost threshold and high maintenance cost

• A
  6% (3)
• B
  4% (2)
• C
  12% (6)
• D
  78% (38)

Explanation

Option D is the wrong description because while cloud computing does offer a low usage cost threshold (pay-as-you-go, no upfront hardware investment), it also features significantly lower maintenance costs - not higher ones - since the cloud provider handles hardware upkeep, infrastructure management, and technical staffing. Options A, B, and C all accurately describe genuine cloud advantages: cloud platforms employ dedicated security teams and provide rapid incident response (A), offer built-in high availability through automatic failover and snapshot backups (B), and allow on-demand, flexible resource scaling without physical hardware changes (C). The error in D is the phrase "high maintenance cost," which is the opposite of reality - reduced operational and maintenance burden is one of the primary financial arguments for moving to the cloud.

Memory tip: Remember that cloud computing replaces capital expenditure and ongoing maintenance with a predictable, provider-managed service model, so both the entry cost and the maintenance cost are lower than self-built - any answer claiming cloud raises maintenance costs is always wrong.
