Question 461 of 982
Describe an analytics workload on Azure →easyMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is that a self-hosted integration runtime is not installed on premises. This is the missing component because Azure Data Factory requires a self-hosted integration runtime to bridge connectivity between the cloud and on-premises SQL Server; without it installed on a machine that can reach the database, the copy activity cannot establish a private network connection and will fail with a connectivity error. On the DP-900 exam, this scenario tests your understanding of integration runtimes as connectivity gateways—specifically when to use a self-hosted IR versus Azure IR or Azure-SSIS IR. A common trap is assuming a public endpoint or firewall rule is the issue, but the error here stems from the absence of the on-premises agent. Memory tip: think of the self-hosted IR as a “bridge” you must physically install—no bridge, no data flow.

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "most likely"

    Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

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

✓

A self-hosted integration runtime is not installed on premises

The pipeline uses a SelfHostedIR integration runtime to connect to on-premises SQL Server. To work, a self-hosted integration runtime must be installed on a machine that can reach the on-premises SQL Server. Option A is wrong because a public endpoint is not needed; the self-hosted IR connects privately. Option B is wrong because Azure SQL Database firewall rules are not the issue (error is connectivity to on-premises). Option D is wrong because the query is valid.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • ✗

    The Azure SQL Database firewall must allow Azure services

    Why it's wrong here

    The error is about connecting to on-premises SQL Server, not Azure SQL.

  • ✓

    A self-hosted integration runtime is not installed on premises

    Why this is correct

    The SelfHostedIR reference requires an actual installed IR agent on a machine that can access the on-premises SQL Server.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The SQL query is invalid

    Why it's wrong here

    The query is syntactically correct.

  • ✗

    The on-premises SQL Server must have a public endpoint

    Why it's wrong here

    The self-hosted IR connects over private network, no public endpoint needed.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
