Question 1

In Informatica Cloud, when processing hierarchical JSON data, which data structure best represents the parent-child relationship between source and target fields?

Accepted Answer

Tree

Answer

Trees naturally represent hierarchical parent-child relationships found in JSON and XML data structures used in Informatica Cloud mappings.

Question 2

Which sorting algorithm has an average-case time complexity of O(n log n) and is commonly used in Informatica's internal sort transformations?

Accepted Answer

Merge sort

Answer

Merge sort achieves O(n log n) average-case complexity and is well-suited for large datasets that Informatica sort transformations process.

Question 3

In Informatica Cloud data pipelines, a FIFO queue is used to buffer records between stages. What is the primary advantage of a FIFO queue in this context?

Accepted Answer

Ensures records are processed in arrival order

Answer

FIFO (First-In-First-Out) queues preserve record ordering, which is critical when sequence matters in pipeline stages.

Question 4

What is the space complexity of storing a lookup table for a joiner transformation with n records from the master source?

Accepted Answer

O(n)

Answer

A joiner transformation stores the master source in memory as a hash table requiring O(n) space proportional to the number of master records.

Question 5

In Informatica Cloud, a lookup transformation uses a hash map internally. What is the average time complexity for a single lookup operation?

Accepted Answer

O(1)

Answer

Hash maps provide O(1) average-case lookup time, which is why Informatica uses them to make lookup transformations efficient.
