CCOA Securing Assets Practice Question
You are implementing 'Just-in-Time' (JIT) access for Azure Virtual Machines using Microsoft Defender for Cloud. A developer complains they cannot request access to a VM. What is the most likely reason?
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 developer lacks the required Azure RBAC permissions to modify the Network Security Group associated with the VM.
Defender for Cloud's JIT VM Access requires the user to have specific RBAC permissions (typically 'Microsoft.Compute/virtualMachines/write') on the resource group or subscription.
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 VM is not joined to an Azure Active Directory domain.
Why it's wrong here
JIT VM access does not require a domain-joined state.
- ✓
The developer lacks the required Azure RBAC permissions to modify the Network Security Group associated with the VM.
Why this is correct
JIT access works by modifying the NSG; without sufficient RBAC permissions to change these rules, the request will fail.
- ✗
The developer lacks the 'Security Reader' role, which is mandatory for requesting JIT access.
Why it's wrong here
Security Reader is a lower-level role and does not grant the write permissions needed to modify NSG rules via JIT.
- ✗
The developer has not enabled 'Multi-Factor Authentication' on their local machine.
Why it's wrong here
While MFA is good practice, it is not a requirement for the JIT request process itself.
