When configuring ECS storage for a data-intensive application, which practices will enhance both performance and data protection?

Question

Options

• AUsing high-performance SSDs for active data sets
• BPeriodic manual backups to an external hard drive
• CEnabling automatic replication to secondary storage
• DImplementing data deduplication and compression techniques

• A
  80% (16)
• B
  20% (4)

Explanation

For data-intensive ECS workloads, high-performance SSDs (A) dramatically reduce I/O latency and increase throughput compared to spinning disks, directly boosting application performance for active datasets. Automatic replication (C) ensures continuous data protection by maintaining synchronized copies across storage tiers without human intervention, minimizing the risk of data loss. Deduplication and compression (D) reduce storage overhead and the volume of data moved across the system, improving both effective throughput and cost efficiency.

Option B is wrong because periodic manual backups are unreliable for data protection - they create gaps between backup windows, are prone to human error, and external hard drives introduce a single point of failure that doesn't scale.

Memory tip: Think "ACD = Active, Continuous, Dense" - SSDs handle Active data fast, replication provides Continuous protection, and deduplication/compression keeps storage Dense (efficient). Manual backups break the "continuous" principle, which is why B is the odd one out.
