  1. Which throughput-optimized EBS HDD type is ideal for big data, data warehouses, and log processing?

    Answer: st1

    Throughput Optimized HDD (st1) targets large, sequential workloads like big data and logs.

  2. What is the default behavior of S3 Block Public Access for newly created buckets?

    Answer: Public access is blocked

    By default S3 blocks public access to new buckets to prevent accidental exposure.

  3. Which encryption option requires the customer to provide and manage their own encryption keys passed with each request?

    Answer: SSE-C

  4. Which AWS service automatically replicates S3 objects to a bucket in a different AWS Region?

    Answer: S3 Cross-Region Replication

    Cross-Region Replication asynchronously copies objects to a bucket in another Region.

  5. What is the smallest retrieval option tier offered by S3 Glacier Flexible Retrieval for fastest access?

    Answer: Expedited

    Expedited retrievals provide the fastest access (minutes) from Glacier Flexible Retrieval.

  6. Which characteristic distinguishes gp3 from gp2 EBS volumes?

    Answer: gp3 lets you provision IOPS and throughput independently of size

    gp3 decouples IOPS and throughput from volume size, unlike gp2 which scales with capacity.

  7. What does Amazon EFS automatically do as you add or remove files?

    Answer: Scales storage capacity elastically

    EFS grows and shrinks automatically as files are added or removed, with no capacity planning.
