Microsoft SC-900 Practice Test 43

Question 420

At the Quayford payments platform, a hub-and-spoke Azure network sends all outbound application traffic directly to the internet despite a requirement for centralized rule enforcement. Which ongoing control best prevents this issue from recurring?

  1. Review peering settings when network addresses change
  2. Review exposure trends and stale findings each patch cycle
  3. Review protected account scope and exclusions during migrations
  4. Audit route tables and firewall rules after adding spokes

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to audit route tables and firewall rules after adding spokes. This result addresses the stated challenge at the Quayford payments platform.

Incorrect Answers

A:

That routine supports vnet peering connectivity, but the relevant ongoing risk requires the team to audit route tables and firewall rules after adding spokes. For the Quayford payments platform, the direct corrective action is to route the approved egress paths through Azure Firewall with governed network and application rules.

B:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to audit route tables and firewall rules after adding spokes. For the Quayford payments platform, the direct corrective action is to route the approved egress paths through Azure Firewall with governed network and application rules.

C:

Review protected account scope and exclusions during migrations is not the primary recurring safeguard for this problem. The team should audit route tables and firewall rules after adding spokes. For the Quayford payments platform, the direct corrective action is to route the approved egress paths through Azure Firewall with governed network and application rules.

Question 421

At the Foxhaven university IT office, a security policy permits outbound web access only to approved domain destinations but a simple IP allow list cannot express the requirement cleanly. Which implementation choice best addresses the situation?

  1. Evaluate NSG rules in their numeric priority order and correct overlapping entries
  2. Configure supported Microsoft Sentinel analytics rules for the defined suspicious sign-in pattern
  3. Configure suitable Azure Firewall application rules to govern supported web destinations
  4. Use secure score as an improvement indicator rather than a guarantee of zero risk

Explanation

Correct Answer

C:

This is the direct security or compliance remedy: configure suitable Azure Firewall application rules to govern supported web destinations. The observed risk is that layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses; a passing acceptance check would show that a permitted web domain is reachable and an excluded domain is denied under the configured policy. This result addresses the stated challenge at the Foxhaven university IT office.

Incorrect Answers

A:

This alternative would be suitable where the first matching NSG rule by priority controls the traffic decision for that rule evaluation. It does not by itself resolve the need to configure suitable Azure Firewall application rules to govern supported web destinations. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

B:

Configure supported Microsoft Sentinel analytics rules for the defined suspicious sign-in pattern addresses a different kind of problem: ingesting logs alone is insufficient for generating intended detection incidents from event conditions. Here the reported weakness is that layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

D:

This focuses on secure score interpretation; it does not directly correct the condition that layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

Question 422

At the Foxhaven university IT office, a security policy permits outbound web access only to approved domain destinations but a simple IP allow list cannot express the requirement cleanly. What risk should the team identify as the primary issue?

  1. Vault secrets keys and certificates have different management features and usage semantics
  2. Layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses
  3. A playbook must have authorization for each downstream action even if Sentinel launched it successfully
  4. Session policies can inspect and constrain certain user actions after initial application sign-in

Explanation

Correct Answer

B:

This identifies the root issue: layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses. At the Foxhaven university IT office, the team should therefore configure suitable Azure Firewall application rules to govern supported web destinations.

Incorrect Answers

A:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

C:

The proposed cause is relevant to sentinel playbook permissions, but it does not explain why layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses in the reported case. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

D:

Session policies can inspect and constrain certain user actions after initial application sign-in. That is not the mechanism that accounts for the stated failure at the Foxhaven university IT office.

Question 423

At the Foxhaven university IT office, a security policy permits outbound web access only to approved domain destinations but a simple IP allow list cannot express the requirement cleanly. What is the strongest acceptance test for this change?

  1. The deployed app reads its approved secret from Key Vault and repository scans find no active credential
  2. A protected test resource reports healthy onboarding while an intentionally unmonitored resource is flagged
  3. A permitted web domain is reachable and an excluded domain is denied under the configured policy
  4. A safe test incident triggers the intended approved workflow with an auditable action record

Explanation

Correct Answer

C:

This tests the real business behavior: a permitted web domain is reachable and an excluded domain is denied under the configured policy. It specifically checks whether the risk that layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses has been reduced. This result addresses the stated challenge at the Foxhaven university IT office.

Incorrect Answers

A:

That observation may be useful for another security or compliance workflow, but the current acceptance test must demonstrate that a permitted web domain is reachable and an excluded domain is denied under the configured policy. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

B:

At the Foxhaven university IT office, a result about defender agent configuration coverage would not show that the team corrected the failure where layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses.

D:

This result would validate soar response automation, not the intended improvement. The needed observation is that a permitted web domain is reachable and an excluded domain is denied under the configured policy. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

Question 424

At the Foxhaven university IT office, a security policy permits outbound web access only to approved domain destinations but a simple IP allow list cannot express the requirement cleanly. Which setting or practice should be reviewed in future?

  1. Review secret permissions and rotation plans after application changes
  2. Review allowed domains and logging after service endpoint changes
  3. Review reopened and unclassified incidents during shift handovers
  4. Reassess telemetry value and retention after adding data sources

Explanation

Correct Answer

B:

This control works beyond the initial remediation because it requires the team to review allowed domains and logging after service endpoint changes. This result addresses the stated challenge at the Foxhaven university IT office.

Incorrect Answers

A:

Review secret permissions and rotation plans after application changes is not the primary recurring safeguard for this problem. The team should review allowed domains and logging after service endpoint changes. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

C:

The option would have the team review reopened and unclassified incidents during shift handovers. For this situation, the preventive control should instead be to review allowed domains and logging after service endpoint changes. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

D:

Although the proposed practice may address cases where log storage and ingestion choices affect cost and the period of evidence available to security investigators, it does not maintain the specific correction here. For the Foxhaven university IT office, the direct corrective action is to configure suitable Azure Firewall application rules to govern supported web destinations.

Question 425

At the Umberfield energy utility, a workload must connect to one specific TCP service on a private network but broad outbound permissions are currently allowed. Which corrective action best meets the requirement?

  1. Attach the WAF policy to the supported application delivery resource serving the protected HTTP traffic
  2. Use Defender for Identity identity threat detections alongside endpoint evidence
  3. Use Microsoft Sentinel to ingest and analyze suitable security events for centralized SIEM visibility
  4. Use Azure Firewall network rules scoped by source destination and protocol or port

Explanation

Correct Answer

D:

For the Umberfield energy utility, the appropriate correction is to use Azure Firewall network rules scoped by source destination and protocol or port. The decisive reason is that network rules support precise transport-level filtering instead of unrestricted connectivity; acceptance evidence is that a permitted source reaches the required TCP port while an unrelated port or destination is denied.

Incorrect Answers

A:

The option addresses the separate situation where a policy object alone cannot inspect requests that bypass its associated listener or endpoint. For this case, the more appropriate response is to use Azure Firewall network rules scoped by source destination and protocol or port. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

B:

This focuses on defender for identity lateral movement; it does not directly correct the condition that network rules support precise transport-level filtering instead of unrestricted connectivity. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

C:

Use Microsoft Sentinel to ingest and analyze suitable security events for centralized SIEM visibility can be useful for another workload, but it leaves the immediate failure unresolved. Here the priority is to use Azure Firewall network rules scoped by source destination and protocol or port. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

Question 426

At the Umberfield energy utility, a workload must connect to one specific TCP service on a private network but broad outbound permissions are currently allowed. Which underlying issue most directly explains this situation?

  1. Distributed denial-of-service attacks overwhelm availability at network scale and are distinct from ordinary authorized usage
  2. Authorized OAuth applications can retain significant data access independent of a user's active browser session
  3. Resource risk depends partly on connections and permissions between infrastructure components
  4. Network rules support precise transport-level filtering instead of unrestricted connectivity

Explanation

Correct Answer

D:

The problem stems from the fact that network rules support precise transport-level filtering instead of unrestricted connectivity. A correct solution would use Azure Firewall network rules scoped by source destination and protocol or port and check that a permitted source reaches the required TCP port while an unrelated port or destination is denied. This result addresses the stated challenge at the Umberfield energy utility.

Incorrect Answers

A:

The proposed cause is relevant to azure ddos volumetric attack protection, but it does not explain why network rules support precise transport-level filtering instead of unrestricted connectivity in the reported case. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

B:

Authorized OAuth applications can retain significant data access independent of a user's active browser session. That is not the mechanism that accounts for the stated failure at the Umberfield energy utility.

C:

The case does not describe the failure mode involving cloud security graph relationships. Its core issue is that network rules support precise transport-level filtering instead of unrestricted connectivity. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

Question 427

At the Umberfield energy utility, a workload must connect to one specific TCP service on a private network but broad outbound permissions are currently allowed. What evidence would justify considering this concern addressed?

  1. A plan review documents the selected tier and verifies its required protected resource coverage
  2. A supported cross-product test incident is visible through the configured integrated workflow
  3. A simulated campaign is searchable by the relevant message or URL indicators
  4. A permitted source reaches the required TCP port while an unrelated port or destination is denied

Explanation

Correct Answer

D:

This is the relevant acceptance result: a permitted source reaches the required TCP port while an unrelated port or destination is denied. It demonstrates the outcome of choosing to use Azure Firewall network rules scoped by source destination and protocol or port. This result addresses the stated challenge at the Umberfield energy utility.

Incorrect Answers

A:

The alternative checks whether a plan review documents the selected tier and verifies its required protected resource coverage, which is not the direct acceptance criterion for the stated problem. The required result is that a permitted source reaches the required TCP port while an unrelated port or destination is denied. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

B:

This result would validate sentinel integration with defender xdr, not the intended improvement. The needed observation is that a permitted source reaches the required TCP port while an unrelated port or destination is denied. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

C:

This verifies a separate issue in security administration. It does not prove that a permitted source reaches the required TCP port while an unrelated port or destination is denied for the reported situation. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

Question 428

At the Umberfield energy utility, a workload must connect to one specific TCP service on a private network but broad outbound permissions are currently allowed. How should the organization sustain the improvement?

  1. Review network and application-layer controls separately
  2. Review firewall rule collections as internal services change
  3. Trend score changes and unresolved high-impact recommendations
  4. Update indicator status as intelligence confidence and freshness change

Explanation

Correct Answer

B:

For the Umberfield energy utility, this maintenance action preserves the fix: review firewall rule collections as internal services change. It should be revisited as the workload evolves.

Incorrect Answers

A:

The option would have the team review network and application-layer controls separately. For this situation, the preventive control should instead be to review firewall rule collections as internal services change. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

C:

That routine supports secure score interpretation, but the relevant ongoing risk requires the team to review firewall rule collections as internal services change. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

D:

The suggested review does not track the condition behind the incident. Sustained improvement requires the team to review firewall rule collections as internal services change. For the Umberfield energy utility, the direct corrective action is to use Azure Firewall network rules scoped by source destination and protocol or port.

Question 429

At the Glenbrook university IT office, a protected backend VM needs a narrowly defined inbound service behind an Azure Firewall public address. Which approach best resolves the identified risk?

  1. Evaluate NSG rules in their numeric priority order and correct overlapping entries
  2. Use Defender for Cloud Apps application risk assessment and sanctioning workflow
  3. Use an authorized Azure Firewall destination network address translation rule and matching network design
  4. Review Defender for Identity suspicious reconnaissance indicators in the on-premises environment

Explanation

Correct Answer

C:

This solution addresses the stated limitation: inbound translation maps an approved external address and port to a protected internal endpoint. Implementing it means the team should use an authorized Azure Firewall destination network address translation rule and matching network design, then verify that a client reaches only the published backend service while unconfigured inbound ports are not forwarded. This result addresses the stated challenge at the Glenbrook university IT office.

Incorrect Answers

A:

Evaluate NSG rules in their numeric priority order and correct overlapping entries can be useful for another workload, but it leaves the immediate failure unresolved. Here the priority is to use an authorized Azure Firewall destination network address translation rule and matching network design. For the Glenbrook university IT office, the direct corrective action is to use an authorized Azure Firewall destination network address translation rule and matching network design.

B:

The suggested action is to use Defender for Cloud Apps application risk assessment and sanctioning workflow, but the facts at the Glenbrook university IT office require a correction for the distinct problem that inbound translation maps an approved external address and port to a protected internal endpoint.

D:

Review Defender for Identity suspicious reconnaissance indicators in the on-premises environment addresses a different kind of problem: abnormal directory enumeration can be a precursor to account or privilege abuse. Here the reported weakness is that inbound translation maps an approved external address and port to a protected internal endpoint. For the Glenbrook university IT office, the direct corrective action is to use an authorized Azure Firewall destination network address translation rule and matching network design.

Question 430

At the Glenbrook university IT office, a protected backend VM needs a narrowly defined inbound service behind an Azure Firewall public address. Which explanation best accounts for the concern?

  1. Layer-seven destination policies can be based on supported domain-aware rules rather than only network addresses
  2. CSPM and cloud workload protection cover complementary posture and active threat concerns
  3. Cloud workload protection provides service-specific threat signals beyond baseline security posture
  4. Inbound translation maps an approved external address and port to a protected internal endpoint

Explanation

Correct Answer

D:

This identifies the root issue: inbound translation maps an approved external address and port to a protected internal endpoint. At the Glenbrook university IT office, the team should therefore use an authorized Azure Firewall destination network address translation rule and matching network design.

Incorrect Answers

A:

The case does not describe the failure mode involving azure firewall application rules. Its core issue is that inbound translation maps an approved external address and port to a protected internal endpoint. For the Glenbrook university IT office, the direct corrective action is to use an authorized Azure Firewall destination network address translation rule and matching network design.

B:

Although CSPM and cloud workload protection cover complementary posture and active threat concerns, the presented symptoms do not support that as the primary cause; they indicate that inbound translation maps an approved external address and port to a protected internal endpoint. For the Glenbrook university IT office, the direct corrective action is to use an authorized Azure Firewall destination network address translation rule and matching network design.

C:

This explanation belongs to a different security or compliance situation. In this case, the observable gap is that inbound translation maps an approved external address and port to a protected internal endpoint. For the Glenbrook university IT office, the direct corrective action is to use an authorized Azure Firewall destination network address translation rule and matching network design.
