Question 420
Following a technical incident debrief at a subscription media service, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: A subnet must permit application traffic on one port while denying unwanted inbound flows. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?
- Assuming deploying a firewall alone verifies every container image and runtime configuration.
- Assuming Sentinel replaces all endpoint, email, and identity sensors that produce security signals.
- Assuming any previously consented app can safely retain every permission indefinitely.
- Assuming an NSG is a web-application attack signature engine that understands SQL injection payloads.
Explanation
Correct Answer
D:Assuming an NSG is a web-application attack signature engine that understands SQL injection payloads. This belief conflicts with this control principle: NSGs evaluate allow or deny rules for network traffic at subnet or interface scope. The appropriate response instead is: Apply appropriately scoped network security group rules to the subnet or network interface.
Incorrect Answers
A:Assuming deploying a firewall alone verifies every container image and runtime configuration. That caution concerns defender for containers; the specific misconception here is: Assuming an NSG is a web-application attack signature engine that understands SQL injection payloads.
B:Assuming Sentinel replaces all endpoint, email, and identity sensors that produce security signals. That caution concerns microsoft sentinel central analytics; the specific misconception here is: Assuming an NSG is a web-application attack signature engine that understands SQL injection payloads.
C:Assuming any previously consented app can safely retain every permission indefinitely. That caution concerns cloud apps application governance; the specific misconception here is: Assuming an NSG is a web-application attack signature engine that understands SQL injection payloads.
Question 421
During a production cutover at a telecom operator, the SOC lead records this concrete requirement: Administrators need browser-based management access to Azure VMs without exposing public RDP or SSH ports. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?
- Use Microsoft Defender Vulnerability Management exposure and recommendation insights.
- Use Azure Bastion for supported private management connections to virtual machines.
- Use Defender XDR advanced hunting queries over available supported data.
- Use Sentinel incident views and related entities to triage the alert chain.
Explanation
Correct Answer
B:Use Azure Bastion for supported private management connections to virtual machines. Azure Bastion provides managed administrative connectivity without requiring a public IP on each VM. To verify, confirm admins reach the VM over Bastion while direct public management ports remain closed.
Incorrect Answers
A:Use Microsoft Defender Vulnerability Management exposure and recommendation insights. That addresses a different task: security needs a prioritized view of software exposure and remediation opportunities on devices. The present requirement concerns azure bastion.
C:Use Defender XDR advanced hunting queries over available supported data. That addresses a different task: analysts need to search supported security telemetry for a new attack technique across endpoints. The present requirement concerns azure bastion.
D:Use Sentinel incident views and related entities to triage the alert chain. That addresses a different task: multiple alerts appear connected to one attacker session and analysts need a unified investigation. The present requirement concerns azure bastion.
Question 422
During a production cutover at a telecom operator, the SOC lead records this concrete requirement: Administrators need browser-based management access to Azure VMs without exposing public RDP or SSH ports.

Question 429
During a new service launch at a wholesale distributor, the enterprise architect records this concrete requirement: A service needs a managed cryptographic key for signing operations, not simply a stored API password. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?
- Use EDR investigation and containment features on the onboarded endpoint.
- Enable relevant Microsoft Defender for Storage protection for eligible cloud storage accounts.
- Use Microsoft Defender for Office 365 for supported email and collaboration threat protection.
- Use the Key Vault key capability for supported cryptographic key operations and permission policy.
Explanation
