Read the first 7 Cloud Infrastructure flashcards as text

  1. What does 'RPO' stand for in cloud disaster recovery planning for imaging systems?

    Answer: Recovery Point Objective

    Recovery Point Objective defines the maximum acceptable amount of data loss measured in time, guiding backup frequency for imaging archives.

  2. A cloud auto-scaling group for an imaging rendering workload should scale based on which metric to best match demand?

    Answer: CPU utilization or custom application metrics

    CPU utilization or application-specific metrics like queue depth most accurately reflect rendering workload demand and trigger appropriate scaling.

  3. Which cloud database type is best suited for storing flexible, schema-less imaging metadata with varying attributes per image?

    Answer: NoSQL document database

    NoSQL document databases accommodate varying metadata schemas per document, making them ideal for heterogeneous imaging metadata.

  4. In cloud infrastructure for imaging, what is the role of an API gateway?

    Answer: Manage, secure, and throttle API calls to backend imaging services

    An API gateway acts as an entry point that handles authentication, rate limiting, and routing for all client requests to imaging backend services.

  5. When configuring VPC security groups for a cloud imaging server, what is the principle of least privilege applied as?

    Answer: Opening only the specific ports required for imaging services

    Least privilege means permitting only the minimum necessary ports and protocols, reducing the attack surface of the imaging server.

  6. Which cloud monitoring approach proactively alerts a DIS team before an imaging storage bucket reaches capacity?

    Answer: Setting CloudWatch/cloud metric alarms on bucket size thresholds

    Metric-based alarms automatically notify operations teams when storage usage crosses defined thresholds, enabling proactive capacity management.

  7. A cloud imaging workflow uses serverless functions to generate thumbnails. What is the key billing advantage of serverless over always-on VMs?

    Answer: You pay only for actual execution time, not idle time

    Serverless billing is based on the number of invocations and execution duration, eliminating costs for idle periods unlike continuously running VMs.
