MD-102 Manage and maintain devices Practice Question

This MD-102 practice question tests your understanding of manage and maintain devices. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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

{
  "@odata.type": "#microsoft.graph.windows10CompliancePolicy",
  "passwordRequired": true,
  "passwordMinimumLength": 6,
  "passwordRequiredType": "deviceDefault",
  "osMinimumVersion": "10.0.19041.0",
  "osMaximumVersion": "10.0.22621.0",
  "storageRequireEncryption": true,
  "activeFirewallRequired": true,
  "defenderEnabled": true
}

Refer to the exhibit. You have applied this compliance policy to a Windows 10 device running build 10.0.19044. The device meets all requirements except that the firewall is disabled. What will be the compliance status of the device?

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

✓

Non-compliant, because the firewall is disabled.

The policy requires activeFirewallRequired to be true. Since the firewall is disabled, the device is non-compliant. Even though other requirements are met, non-compliance in one area makes the device non-compliant. Option A is incorrect because the policy does not have a grace period. Option B is incorrect because the device is non-compliant. Option D is incorrect because the policy is applicable.

Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Answer analysis

Option-by-option breakdown

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

  • ✗

    Non-compliant, because the OS version is not within the allowed range.

    Why it's wrong here

    The OS version is within the allowed range.

  • ✗

    Compliant, because the policy includes a grace period for firewall.

    Why it's wrong here

    No grace period is specified in the policy.

  • ✗

    Compliant, because the OS version is within the allowed range.

    Why it's wrong here

    OS version is within range, but firewall requirement is not met.

  • ✓

    Non-compliant, because the firewall is disabled.

    Why this is correct

    Active firewall is required; disabling it makes the device non-compliant.

    Related concept

    OSPF neighbours must agree on key parameters.

Common exam traps

Common exam trap: OSPF can fail even when IP connectivity looks correct

OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.

Detailed technical explanation

How to think about this question

OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.

KKey Concepts to Remember

  • OSPF neighbours must agree on key parameters.
  • Router ID selection can affect neighbour relationships and LSDB output.
  • OSPF cost influences the preferred path.
  • A route can appear in OSPF information but not become the installed route.

TExam Day Tips

  • Check area mismatch first when OSPF adjacency fails.
  • Review passive interfaces when a network is advertised but no neighbour forms.
  • Use show ip ospf neighbor and show ip route clues carefully.

Key takeaway

OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

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.

What to study next

Got this wrong? Here's your next step.

Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related MD-102 OSPF questions on adjacency and route selection.
