The cost to perform a snapshot refresh may depend on whether the snapshot is simple or complex.

Solution (By Examveda Team)

The statement is true. The cost to perform a snapshot refresh may indeed depend on whether the snapshot is simple or complex, as complex snapshots may require more resources and time for refreshing compared to simple snapshots.

Option A: True
This option correctly affirms the statement provided in the question. The cost associated with performing a snapshot refresh can vary based on several factors, including the complexity of the snapshot. A simple snapshot, which captures a straightforward representation of data without extensive transformations or filtering, may be relatively inexpensive to refresh. In contrast, a complex snapshot, which involves aggregations, joins, or other computationally intensive operations, may require more resources and time for refreshing. The complexity of the snapshot impacts the amount of processing and data movement required during the refresh process, which in turn can affect the overall cost in terms of time, CPU utilization, and network bandwidth.

Option B: False
This option contradicts the statement provided in the question. The cost to perform a snapshot refresh can indeed vary based on the complexity of the snapshot. Complex snapshots may require more resources and time for refreshing compared to simple snapshots, as they involve additional processing and data manipulation tasks. Therefore, the complexity of the snapshot is an important factor to consider when assessing the cost and performance implications of snapshot refresh operations.

Therefore, in response to the question, the correct option is True (Option A).
