Which cloud storage class is most cost-effective for digital imaging archives that are accessed less than once per year?
Answer: Glacier Deep Archive
Glacier Deep Archive offers the lowest cost for long-term archival data retrieved rarely, making it ideal for inactive imaging archives.
A DIS professional needs to replicate imaging data across two geographic regions for disaster recovery. Which strategy best achieves this?
Answer: Cross-region replication with versioning enabled
Cross-region replication with versioning ensures data is duplicated to a geographically separate region, protecting against regional outages.
When uploading large DICOM imaging files to cloud storage, which transfer method minimizes upload time and reduces failure risk?
Answer: Multipart upload
Multipart upload splits large files into chunks uploaded in parallel, improving throughput and allowing resume on partial failure.
In a cloud imaging pipeline, what is the primary purpose of an object lifecycle policy?
Answer: To automatically transition or delete objects based on age
Lifecycle policies automate transitioning objects to cheaper storage tiers or deleting them after a defined period, reducing costs.
Which network architecture element reduces latency for globally distributed imaging clients retrieving the same radiographic files?
Answer: Content Delivery Network (CDN)
A CDN caches content at edge locations near users, dramatically reducing retrieval latency for frequently accessed imaging files.
A hospital imaging system must ensure that cloud-stored patient images are encrypted with keys the hospital controls. Which approach satisfies this?
Answer: Client-side encryption with customer-managed keys (CMK)
Customer-managed keys (CMK) give the hospital full control over encryption keys, ensuring they can revoke access independent of the cloud provider.
Which cloud service model allows a DIS professional to deploy a custom PACS application without managing the underlying operating system?
Answer: Platform as a Service (PaaS)
PaaS provides a managed runtime environment where developers deploy applications without patching or maintaining the underlying OS.
