AI-102 Implement an agentic solution Practice Question

Exhibit

Refer to the exhibit.
$agents = Get-AzAIAgent -ResourceGroupName 'rg-agent' -SubscriptionId 'sub-123'
foreach ($agent in $agents) {
    if ($agent.Properties.Tools.Count -eq 0) {
        Write-Output "Agent $($agent.Name) has no tools configured."
    }
}

You run the PowerShell script shown to audit your Azure AI Agent Service agents. The script outputs that several agents have no tools configured. What is the impact on those agents?

⚠ Common exam trap

Many candidates assume agents must have tools to be functional or deployed, but Azure AI Agent Service allows tool-less agents that operate as pure language models, and the exam tests understanding that tools are optional for basic Q&A but required for action-oriented tasks.

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

✓

The agents can only respond to queries using the model's built-in knowledge, without ability to perform actions

Azure AI Agent Service agents without tools configured rely solely on the model's built-in knowledge (e.g., GPT-4o's training data) to generate responses. They cannot execute external actions like calling APIs, querying databases, or running code, which are enabled only when tools (e.g., code interpreter, function calling, or Azure Functions) are explicitly attached. This is by design: tools extend the agent's capabilities beyond the model's static knowledge.

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 agents cannot be deployed until tools are added
Why it's wrong here
Deployment works without tools.
✓
The agents can only respond to queries using the model's built-in knowledge, without ability to perform actions
Why this is correct
No tools means no external actions.
✗
The agents cannot start conversations with users
Why it's wrong here
Conversation starters still work.
✗
The agents will use default tools provided by Azure
Why it's wrong here
No default tools are added.
