   An ECS administrator is investigating a security incident where a disk was removed from the cluster. The administrator needs to determine if the data on the disk is at risk. Which factor is most important in assessing the risk?

   • AWhether the disk was securely erased before removal.
   • BWhether the disk was part of a replication group.
   • CWhether the disk was used for metadata or object data.
   • DWhether D@RE was enabled on the cluster.

   An ECS administrator is planning to enable D@RE on an existing cluster that stores production data. The administrator needs to understand the operational impact before proceeding. Which operational consideration is most important to communicate to the team?

   • AEnabling D@RE requires a full cluster rebuild and data migration.
   • BD@RE encrypts data at rest, but performance may be slightly impacted due to encryption overhead.
   • CD@RE automatically encrypts data in transit between ECS nodes.
   • DD@RE requires all client applications to be updated to support encryption.

   A financial services firm is deploying ECS to store customer transaction records. The compliance team requires that data written to the object store be encrypted at the storage layer, independent of any application-level encryption, and that the encryption keys be managed by the ECS platform itself. The storage administrator is configuring the cluster. Which configuration satisfies the compliance requirement?

   • AUse ECS's built-in data deduplication to reduce the volume of stored data.
   • BEnable D@RE on the ECS storage pool and rely on the platform-managed keys.
   • CConfigure the application to encrypt objects with customer-managed keys before writing to ECS.
   • DEnable TLS on all client connections to the ECS endpoint.

   An ECS administrator is troubleshooting a performance issue after enabling D@RE. The administrator notices that write operations are slower than expected. Which factor is most likely contributing to the performance degradation?

   • AThe storage pool is configured with a low redundancy factor.
   • BThe client applications are not using multipart upload for large objects.
   • CThe encryption algorithm used by D@RE is CPU-intensive.
   • DThe AD integration is causing authentication delays for every write.

   What is an operational implication of enabling D@RE on an ECS system?

   • AThe system will automatically re-encrypt all existing data without any administrator action.
   • BThe system will no longer support data deduplication because encrypted data cannot be deduplicated.
   • CThe system will require a reboot to apply the encryption settings to all nodes.
   • DThe system will experience a slight performance overhead due to encryption and decryption operations.
