You are designing an SAP on Azure production landscape. The landscape must ensure service availability in the event of an Azure datacenter failure. What should you include in the design?

Question

Options

• Aan availability zone
• Ba fusion group
• Can availability set
• Da proximity placement group

• A
  89% (24)
• B
  7% (2)
• C
  4% (1)

Explanation

Availability Zones protect against datacenter-level failures by distributing resources across physically separate facilities within the same Azure region - each zone has independent power, cooling, and networking. For SAP production landscapes requiring high availability against a full datacenter outage, zones are the correct architectural choice.

Why the distractors are wrong:

• B. Fusion group - not a real Azure construct; a distractor.
• C. Availability set - protects against rack-level failures (hardware/software updates within a single datacenter), but does not protect against an entire datacenter going down.
• D. Proximity placement group - reduces network latency by co-locating VMs, but offers zero redundancy against datacenter failure.

Memory tip: Think Zone = Zone-wide disaster protection (cross-datacenter), Set = Server/rack-level protection (within one datacenter). When the question mentions "datacenter failure," the answer is always Zone.
