Question 410

An architecture proposal for cosmos db consistency and nosql choices relies on the following approach: Assume strong consistency has identical latency and topology support as eventual. Which specific failure or mismatch should the design reviewer identify?

  1. Eventual consistency does not guarantee session read-your-writes.
  2. Database server administration can be disproportionate for simple key-value storage.
  3. Removing live blobs can destroy application data unrelated to obsolete versions.
  4. Higher consistency entails availability and geographic limitations.

Explanation

Correct Answer

D:

Assume strong consistency has identical latency and topology support as eventual. Higher consistency entails availability and geographic limitations.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Choose eventual consistency and promise every new read immediately sees its own writes.' not to the recommendation under review. Here, Higher consistency entails availability and geographic limitations.

B:

That assessment refers to the separate proposal 'Select a full SQL VM solely because every entity has two key columns.' not to the recommendation under review. Here, Higher consistency entails availability and geographic limitations.

C:

This concern applies to Delete every current object indiscriminately to clear its old versions. in another design data storage solutions for semi-structured and unstructured data design. The current proposal specifically fails because higher consistency entails availability and geographic limitations.

Question 411

  1. Inspect version listings after the lifecycle job completes.
  2. Load-test latency and read correctness under supported topology.
  3. Test writes followed by cross-region reads with the same client session.
  4. Test partition-key and row-key queries with realistic entity counts.

Explanation

Correct Answer

B:

Results quantify the guarantee and performance trade-off.

Incorrect Answers

A:

This is a test for An app needs to remove temporary object versions older than the approved retention window. The requirement here is instead demonstrated by load-test latency and read correctness under supported topology.

The current proposal specifically fails because database server administration can be disproportionate for simple key-value storage.

Question 414

Acceptance testing must establish the following operational result: Key-based access proof validates the model's suitability. Which verification action most directly establishes that outcome?

  1. Test partition-key and row-key queries with realistic entity counts.
  2. Inspect disk SKU and supported zone failure properties.
  3. Test writes followed by cross-region reads with the same client session.
  4. Load-test latency and read correctness under supported topology.

Explanation

Correct Answer

A:

Key-based access proof validates the model's suitability.

Incorrect Answers

B:

This is a test for A platform architect wants all managed disks to survive zonal failure simply because the VMs use zones. The requirement here is instead demonstrated by test partition-key and row-key queries with realistic entity counts.

C:

That verification addresses the different requirement: A globally distributed application needs guaranteed read-your-writes for a user's own session across regions. It does not directly establish key-based access proof validates the model's suitability.

D:

That verification addresses the different requirement: A financial workflow prioritizes strict read ordering over maximum global read availability. It does not directly establish key-based access proof validates the model's suitability.

Question 415

Daily batch files require mapping, copying, transformation and scheduled dependencies across systems. Which Azure architecture choice best meets this requirement?

  1. Open the on-premises database broadly to anonymous Internet access.
  2. Schedule dozens of unaudited VM cron jobs with hardcoded credentials.
