Zorluk: KolayResilient and Highly Available Storage Infrastructure

A logistics company needs to archive historical delivery route logs. The logs must be stored with high durability across multiple Availability Zones. In the event of an audit, the company must be able to retrieve any archived log file within 10 minutes to satisfy their SLA. Which two storage configurations will meet these requirements? (Select TWO.)

  1. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)Cevap
  2. Amazon S3 Glacier Instant RetrievalCevap
  3. C
    Amazon S3 Glacier Flexible Retrieval using Standard retrievals
  4. D
    Amazon S3 Glacier Deep Archive
  5. E
    Amazon EBS Provisioned IOPS SSD (io2) volumes with Multi-Attach enabled across multiple Availability Zones

Cevap

The correct configurations are Amazon S3 Standard-Infrequent Access (S3 Standard-IA) and Amazon S3 Glacier Instant Retrieval.
Amazon S3 Standard-Infrequent Access (S3 Standard-IA) and Amazon S3 Glacier Instant Retrieval are the correct choices. Both storage classes replicate data across at least three Availability Zones, ensuring high availability and resilience. Furthermore, both offer millisecond-level access, ensuring that archived logs can be retrieved well within the 10-minute SLA constraint.

Adım Adım Çözüm

1
Analyze the Availability Zone resilience requirement.
The storage solution must replicate data across multiple Availability Zones, which rules out single-AZ options.
This filters out configurations that are bound to a single Availability Zone, such as Amazon EBS volumes.
2
Evaluate the retrieval time constraints (Recovery Time Objective).
The target retrieval time must be under 10 minutes.
This filters out standard archive classes with long retrieval delays, such as Amazon S3 Glacier Flexible Retrieval with Standard retrieval (3-5 hours) or Amazon S3 Glacier Deep Archive (12 hours).
3
Select the configurations that support both multi-AZ replication and rapid retrieval.
Amazon S3 Standard-IA and Amazon S3 Glacier Instant Retrieval meet all constraints.
Both storage classes offer active, millisecond-level retrievals while storing data redundantly across three or more Availability Zones.
