Question 1

In Informatica Cloud, when detecting duplicate records using a sorted input, which algorithm approach has the best time efficiency?

Accepted Answer

Sort then scan adjacent pairs in O(n log n)

Answer

Sorting first (O(n log n)) and then doing a single linear scan to find adjacent duplicates is more efficient than the brute-force O(n²) comparison.

Question 2

Which data structure would you use to implement an undo/redo feature in an Informatica Cloud mapping designer session?

Accepted Answer

Stack

Answer

Stacks provide LIFO behavior, where the most recent action is undone first, making them perfect for undo/redo functionality.

Question 3

An Informatica Cloud pipeline processes records arriving from multiple sources with priority levels. Which data structure should manage processing order?

Accepted Answer

Priority queue (min-heap)

Answer

A priority queue (min-heap) efficiently dequeues the highest-priority record in O(log n) time, ideal for priority-based record processing.

Question 4

What is the worst-case time complexity for searching an unsorted array of n records in Informatica Cloud's flat file source?

Accepted Answer

O(n)

Answer

An unsorted array requires a linear scan in the worst case, visiting every element once, giving O(n) complexity.

Question 5

In Informatica Cloud, a sequence generator transformation produces monotonically increasing values. Which data structure property does this enforce?

Accepted Answer

Monotonic stack property

Answer

A monotonic stack maintains elements in strictly increasing or decreasing order, mirroring the always-increasing values from a sequence generator.
