Three statements. One is false 1. Webhooks are triggered by the server when an event occurs 2. If your Webhook endpoint is down, the event is permanently lost with no way to recover it 3. Webhook payloads should be verified using a signature before processing Which one is the lie?

@EOEboh Prompt Engineering=how you ask RAG=what knowledge you fetch Fine-Tuning=how you train the brain itself Prompt engineering improves outputs without changing the model,RAG augments responses with external data, and fine-tuning modifies the model itself for domain-specific accuracy.

Interviewer: What is the difference between Fine-Tuning, RAG and Prompt Engineering? When would you choose each?

@ashoKumar89 Replica = eventually consistent Primary = source of truth For read-after-write scenarios, you should read from the primary to avoid replication lag and ensure the user sees their latest update.

You have a Primary DB and Read replicas. A simple request comes in: GET /user/profile The user just updated their profile 2 seconds ago. Do you hit the primary or a replica? Most developers get this wrong.

@yourclouddude both operands are strings, Python concatenates them, resulting in '53' instead of performing arithmetic addition.

@SumitM_X DISTINCT = deduplicate GROUP BY = group + (optional) aggregate Both DISTINCT and GROUP BY usually have similar performance since they use the same underlying operations like sorting or hashing, unless aggregations or optimizer differences come into play.

Which Query has better performance ? SELECT DISTINCT dept FROM emp; vs SELECT dept FROM emp GROUP BY dept;

@RHSTUDYZONE answer is 16.
