Step-by-Step Solution
Solution:
Step 1: Understand instance family memory focus
R family is memory optimized, offering more memory per vCPU than others.Step 2: Compare memory per vCPU for given types
r5.large has 16 GiB RAM and 2 vCPUs (8 GiB/vCPU), higher than m5.large (8 GiB/2 vCPU = 4 GiB/vCPU), c5.large (4 GiB/2 vCPU = 2 GiB/vCPU), t3.large (8 GiB/2 vCPU = 4 GiB/vCPU).Final Answer:
r5.large -> Option AQuick Check:
Memory optimized = r5.large [OK]
Quick Trick: Memory optimized = R family (r5, r6g) [OK]
Common Mistakes:
- Assuming m5.large has more memory per vCPU
- Confusing compute-optimized c5.large as memory heavy
- Thinking burstable t3.large has highest memory per vCPU
