Question 26

Explain high-frequency data replication

Answer 26

A source system asynchronously replicates data to a target system in near–real time at high scale.

Question 27

Explain pub/sub

Answer 27

Salesforce publishes an event (such as a record created, changed, deleted, and so on) with no knowledge of who may be on the receiving end. Any number of subscribers listen for these events and process them accordingly.

Question 28

In the layer approach, what 4 dimensions are used to evaluate integration patterns and solutions?

Answer 28

1. Layers (UI/Bus.Process/Data) 2. Volume 3. Timing (sync/async) 4. Direction

Question 29

In addition to evaluating integration dimensions, what else is important to consider in integration strategy?

Answer 29

1. Security Requirements 2. Error-Handing & Recovery 3. Coupling

Question 30

What is idempotency and why is it important?

Answer 30

Idempotency ensures that repeated requests (e.g., a user clicking the same button multiple times) do not cause duplicate processing or data corruption. To achieve this, include a unique message ID in requests and check for duplicates before processing in the external system.
