SAP-C02 Continuous Improvement for Existing Solutions Practice Question
Network Topology
A company is using t3.large instances in an Auto Scaling group. They want to launch instances that support both x86_64 and arm64 architectures. Based on the exhibit, can they meet this requirement with t3.large?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
No, because t3.large instances only support x86_64 architecture.
T3.large instances only support the x86_64 architecture. They do not support arm64. Therefore, the company cannot meet the requirement of supporting both x86_64 and arm64 architectures with t3.large instances. Options B and D are incorrect because t3.large does not support arm64, and a custom AMI cannot add architecture support beyond what the instance type offers. Option C is incorrect because t3.large is a current generation instance type, but that is not relevant to the architecture support limitation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
No, because t3.large instances only support x86_64 architecture.
Why this is correct
T3 instances are exclusively x86_64; arm64 requires Graviton-based families such as t4g, m6g or c7g. Since the stem demands a single instance type supporting both architectures, t3.large cannot satisfy it — no x86 instance does. The requirement is therefore unmet with t3.large.
- ✗
Yes, because t3.large supports both architectures.
Why it's wrong here
t3.large runs exclusively on x86_64 Intel hardware; arm64 requires Graviton-based families such as t4g or m6g. The claim tempts because t3 instances are flexible across sizes and credits, but that flexibility concerns CPU burst behaviour, not instruction-set architecture, so a single t3.large cannot serve both architectures.
- ✗
No, because t3.large is not a current generation instance type.
Why it's wrong here
t3.large is a current-generation burstable instance; generation is irrelevant to the architecture question, since t3 is x86_64-only regardless. The distractor tempts candidates who conflate instance generation with processor support, and generation would matter where the requirement concerned newer features such as Nitro-based networking or Graviton pricing.
- ✗
Yes, but only if they use a custom AMI that supports both architectures.
Why it's wrong here
An AMI carries binaries compiled for one instruction set; it cannot make x86_64 silicon execute arm64 code. The option tempts because custom AMIs do solve many compatibility problems, and it would be correct where the requirement was a bespoke OS image on a single supported architecture, not dual-architecture support.
