AI-102 Practice Question: Implement natural language processing solutions

This AI-102 practice question tests your understanding of implement natural language processing solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Exhibit

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "resources": [
    {
      "type": "Microsoft.CognitiveServices/accounts",
      "apiVersion": "2022-12-01",
      "name": "myLanguageService",
      "location": "[resourceGroup().location]",
      "sku": {
        "name": "S0"
      },
      "kind": "TextAnalytics",
      "properties": {
        "customSubDomainName": "mylanguageservice",
        "networkAcls": {
          "defaultAction": "Deny",
          "virtualNetworkRules": [],
          "ipRules": []
        }
      }
    }
  ]
}

Refer to the exhibit. You deploy this ARM template to create an Azure AI Language Service resource. After deployment, you try to call the Language Service API from your application but receive a 403 Forbidden error. What is the most likely cause?

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

✓

The network ACLs block all traffic because no IP rules are defined

The ARM template in the exhibit does not include any IP rules in the network ACLs section, which means the default behavior for Azure AI Language Service is to deny all traffic when network ACLs are explicitly configured. Even though the resource is deployed successfully, the absence of allowed IP ranges or a virtual network rule causes the service to block all API calls, resulting in a 403 Forbidden error.

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 SKU S0 does not support API calls from applications

    Why it's wrong here

    S0 supports API calls.

  • ✗

    The resource kind is set incorrectly for Language Service

    Why it's wrong here

    TextAnalytics is correct for Language Service.

  • ✓

    The network ACLs block all traffic because no IP rules are defined

    Why this is correct

    Deny default with no allowed IPs blocks all calls.

    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 custom subdomain name is invalid

    Why it's wrong here

    The name is valid.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often assume a 403 error is always due to authentication issues (e.g., missing API key), but in this context, the error is caused by network ACLs blocking traffic, which is a common misdirection in AI-102 questions about ARM template deployments.

Detailed technical explanation

How to think about this question

When you define network ACLs in an ARM template for Azure AI Language Service, the default action is 'Deny' unless you explicitly add IP rules or virtual network rules. The 403 Forbidden error occurs because the API request is blocked at the network layer before it reaches the service endpoint. In real-world scenarios, you must either specify allowed IP ranges or set the default action to 'Allow' (by omitting the networkAcls property entirely) to permit public traffic.

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.

TExam Day Tips

  • 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.
