You launched an instance with type c5.large but your application needs more memory. Which instance type should you choose to fix this issue without changing the CPU count?

Ar5.large

Bc5.xlarge

Ct3.large

Dm5.large

Step-by-Step Solution

Solution:

Step 1: Identify current instance specs
c5.large has 2 vCPUs and 4 GiB memory.
Step 2: Find instance with same vCPU but more memory
r5.large has 2 vCPUs and 16 GiB memory, increasing memory without changing CPU count.
Final Answer:
r5.large -> Option A
Quick Check:
More memory, same CPU = r5.large [OK]

Quick Trick: Keep vCPU same, pick memory-optimized with same size [OK]

Common Mistakes:

MISTAKES

Choosing c5.xlarge which doubles CPU and memory
Picking t3.large which is burstable, not memory optimized
Selecting m5.large which has less memory (8 GiB) than r5.large
