A cloud administrator is given a requirement to maintain a copy of all system logs for seven years. All servers are deployed in a public cloud provider's environment. Which of the following is the…

While a long-term storage repository at the cloud provider is a valid option for retention, it would incur additional costs for the dedicated storage service and potentially data transfer costs to move logs from the servers to this repository, making it less cost-efficient than local storage.

Scheduling a nightly job to archive and compress logs on the server itself is the most cost-efficient solution because it leverages existing server storage without incurring additional costs for separate cloud storage services, data egress, or inter-service data transfer fees. Compression also reduces the storage footprint on the existing disk, further optimizing costs.

Configuring SMTP services to email logs is highly inefficient and expensive for long-term, large-volume log retention due to email size limits, potential security risks, and the operational overhead of managing email for storage.

Copying all logs to a single server before retention creates a single point of failure and adds network transfer costs and storage burden to that one server, which is less efficient and scalable than managing logs locally on each server.
