Which access pattern is likely to result in the best performance on an ECS system?

Accessing objects only during peak hours

Random access to small objects with no locality

Sequential access to large objects

Accessing objects from multiple geographic regions simultaneously

A research institution stores genomics data on ECS. Files range from 100 MB to 10 GB, and researchers frequently access the same files concurrently from multiple compute nodes. They report variable performance, with some reads taking much longer than others. Which data layout or access pattern factor is most likely causing the variability?

Incorrect chunk size for large files

Uneven object distribution across storage nodes

Insufficient network bandwidth to the compute nodes

Low memory on the storage nodes

Which hardware component in an ECS node is most critical for handling a high number of concurrent client connections?

The network interface cards (NICs)

When evaluating the impact of memory on ECS performance, which of the following is a primary consideration?

The number of memory slots populated with dummy modules

The memory's color coding on the motherboard

The amount of memory available for caching metadata and frequently accessed data

The memory's physical size in millimeters
