What two things must be considered when creating a bucket on an ECS cluster? (Select 2)

Question

Options

• ABuckets should be created with a unique name within a federation.
• BBuckets can be accessed from any VDC belonging to the same replication group.
• CBuckets should be created at the VDC closest to the application accessing and updating the objects.
• DS3 buckets support NFS and Centera CAS data access.

• A
  4% (1)
• B
  85% (22)
• D
  12% (3)

Explanation

When creating a bucket on an ECS (Elastic Cloud Storage) cluster, you must consider replication group accessibility and geographic proximity to the application. Option B is correct because buckets assigned to a replication group are accessible from any VDC (Virtual Data Center) within that group, making data available across sites without manual intervention. Option C is correct because placing the bucket at the VDC geographically nearest to the application minimizes latency and improves read/write performance for objects.

Why the distractors are wrong:

• A is incorrect because bucket name uniqueness is scoped to the namespace, not the entire federation - this is a common misstatement of the actual ECS constraint.
• D is incorrect because S3 buckets specifically use the S3 protocol; NFS and Centera CAS are separate access protocols in ECS and are not supported on S3-type buckets.

Memory tip: Think "Where it lives, where it reaches" - the bucket should live close to the app (C) and it reaches across the replication group (B). These are the two placement decisions that matter at creation time.
