Security is the basis of architecture design. Designing a secure architecture can minimize the risk of system intrusion and ensure business operation. Which of the following is not a high-security…

Question

Options

• AManage IAM through a unified identity, distinguishing system roles and corresponding
• BUse the elastic scaling service AS to adjust the number of instances according to the actual
• CMulti-dimensional monitoring of the system, real-time assessment of system risk
• DUse cloud certificate management CCM to manage certificates

• A

• B
  72% (18)
• C
  16% (4)
• D
  8% (2)

Explanation

Option B describes elastic auto-scaling, which is a feature designed for availability, performance, and cost efficiency - adjusting compute capacity based on demand has no direct role in securing a system against intrusion or protecting data. Options A, C, and D are each core security architecture concerns: unified IAM with role separation enforces least-privilege access control; multi-dimensional monitoring with real-time risk assessment enables threat detection and incident response; and certificate management via CCM ensures encrypted communications and authenticated identities. The key distinction is that auto-scaling addresses operational resilience, while the other three options directly address confidentiality, integrity, or access control.

Memory tip: Ask yourself whether each option "keeps bad actors out or detects them" - IAM controls who enters, monitoring watches for threats, and certificates authenticate identities. Auto-scaling only adjusts how many servers are running, which has nothing to do with keeping attackers out.
