Zorluk: OrtaAmazon S3 Storage Class and Lifecycle Optimization

A company stores application logs in an Amazon S3 bucket. The logs are stored in the S3 Standard storage class by default. The logs are frequently accessed for the first 30 days. After 30 days, they are rarely accessed but must be available immediately if a security audit occurs. After 180 days, the logs are only needed for annual compliance reviews where a retrieval time of up to 12 hours is acceptable. The total retention period is 365 days, after which the logs must be deleted. A SysOps administrator is configuring an S3 Lifecycle policy to minimize storage costs. Which actions should the SysOps administrator configure in the S3 Lifecycle rules to meet these requirements? (Select TWO.)

  1. Transition objects from S3 Standard to S3 Standard-IA after 30 daysCevap
  2. Transition objects from S3 Standard-IA to S3 Glacier Deep Archive after 180 daysCevap
  3. C
    Transition objects from S3 Standard-IA to S3 Intelligent-Tiering after 90 days
  4. D
    Transition objects from S3 Glacier Deep Archive to S3 Standard-IA after 270 days
  5. E
    Transition objects from S3 Standard-IA to S3 Glacier Deep Archive 15 days after transitioning to S3 Standard-IA

Cevap

The SysOps administrator should configure the S3 Lifecycle policy to transition objects from S3 Standard to S3 Standard-IA after 30 days, and transition objects from S3 Standard-IA to S3 Glacier Deep Archive after 180 days.
The correct configuration consists of transitioning objects from S3 Standard to S3 Standard-IA after 30 days, and then from S3 Standard-IA to S3 Glacier Deep Archive after 180 days. This sequence aligns with the requirements of frequent access for 30 days, rare but immediate access up to day 180, and annual compliance access (up to 12 hours retrieval) afterwards, while minimizing costs.

Adım Adım Çözüm

1
Analyze the access and retrieval requirements for the first phase (0-30 days).
The logs are frequently accessed for the first 30 days, so they should remain in the default S3 Standard storage class during this period.
S3 Standard is optimized for active, frequently accessed data.
2
Analyze the access and retrieval requirements for the second phase (30-180 days).
After 30 days, access becomes rare but must remain immediate. Transitioning to S3 Standard-IA at day 30 satisfies this.
S3 Standard-IA has a minimum storage duration of 30 days and provides rapid millisecond access at lower storage costs.
3
Analyze the access and retrieval requirements for the third phase (after 180 days).
After 180 days, logs are only needed for annual reviews where a 12-hour retrieval is acceptable. Transitioning from S3 Standard-IA to S3 Glacier Deep Archive at day 180 meets this requirement at the lowest cost.
S3 Glacier Deep Archive supports 12-hour Bulk retrievals and is the most cost-effective storage class for long-term archiving.

Anahtar Kavram

Amazon S3 Lifecycle rules allow you to transition objects to cost-effective storage classes based on access patterns, complying with unidirectional transition constraints (e.g., from Standard to Standard-IA, and Standard-IA to Glacier Deep Archive).
