AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An EC2 m6i.large instance copies a 2 TB tar file to an S3 bucket with the command aws s3 cp /data/archive.tar s3://corp-logs/. Network CloudWatch metrics show the instance can sustain 8 Gbps, but the transfer stalls around 500 Mbps and uses only one TCP connection. Without changing the instance type or writing custom code, which AWS CLI adjustment will MOST increase upload throughput?

  • Use --storage-class GLACIER in the cp command so the object uploads into the GLACIER storage class.

  • Set multipart_chunksize = 5MB to create many smaller parts during the upload.

  • Turn off enhanced networking on the instance to eliminate driver overhead.

  • Add an S3 transfer configuration in ~/.aws/config such as:

    [s3]
multipart_threshold = 64MB
max_concurrent_requests = 50
