AWS - S3 Fundamentals

You have this lifecycle rule but objects are not being deleted as expected:

{
  "Rules": [{
    "Status": "Enabled",
    "Expiration": {"Days": 0}
  }]
}

What is the most likely reason?

AThe rule is missing a prefix filter

BSetting 'Days' to 0 is invalid; it must be at least 1

CExpiration requires a 'Transition' action to work

DThe bucket versioning must be disabled for expiration to work

Step-by-Step Solution

Solution:

Step 1: Check the 'Days' value
Expiration 'Days' must be a positive integer; 0 is not valid.
Step 2: Understand expiration behavior
Objects can only expire after at least 1 day; zero days means immediate expiration which is unsupported.
Final Answer:
Setting 'Days' to 0 is invalid; it must be at least 1 -> Option B
Quick Check:
Expiration does not require transition or prefix; versioning affects delete markers [OK]

Quick Trick: Expiration days must be >= 1 [OK]
