DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing

Your company has an Azure Data Factory pipeline that ingests data from multiple sources into Azure Data Lake Storage Gen2. The pipeline uses a self-hosted integration runtime (IR) running on an on-premises Windows server. Recently, the pipeline started failing with 'Connection timed out' errors during peak hours. You suspect network congestion. You need to resolve this issue with minimal cost and without modifying the pipeline activities. What should you do?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Scale out the self-hosted IR by adding more nodes to the cluster.

Scaling out the self-hosted IR by adding more nodes distributes the load and reduces timeout issues. Option A is wrong because Azure ExpressRoute provides dedicated bandwidth but is costly and overkill for this scenario. Option B is wrong because increasing the polling interval does not fix network timeouts; it only changes how often the activity checks for data. Option D is wrong because migrating to Azure-SSIS IR is expensive and unnecessary for this pipeline.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Implement Azure ExpressRoute to provide dedicated bandwidth.

    Why it's wrong here

    Overkill and costly for this issue.

  • Increase the 'Polling Interval' setting in the copy activity.

    Why it's wrong here

    Polling interval affects status check, not connectivity.

  • Scale out the self-hosted IR by adding more nodes to the cluster.

    Why this is correct

    Distributes load and improves throughput.

  • Migrate the self-hosted IR to Azure-SSIS IR.

    Why it's wrong here

    Expensive and not a direct solution for load.
