The answer is creating an incident in ServiceNow, blocking an IP address, and resetting a user password. These three actions are valid because Microsoft Sentinel playbooks, built on Azure Logic Apps, automate incident response by integrating with external systems via connectors—ServiceNow for ticketing, threat intelligence feeds for IP blocking, and Azure AD for password resets. On the SC-900 exam, this question tests your understanding of playbook capabilities versus limitations, often appearing as a multi-select trap where distractors like “modify firewall rules” or “install software” seem plausible but are incorrect because playbooks trigger automation rather than performing direct infrastructure changes. A common memory tip is to remember that playbooks handle logical, user- or system-level actions (tickets, blocks, resets) but never direct hardware or software deployment. For the exam, think “ticket, block, reset” as the three core automated incident response actions.
SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which THREE actions can Microsoft Sentinel perform as part of automated incident response using playbooks?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Block an IP address on a firewall
Option A is correct because playbooks can create incidents in other systems. Option B is correct because playbooks can block IP addresses. Option C is correct because playbooks can reset user passwords. Option D is wrong because playbooks cannot directly modify firewall rules; they can trigger automation. Option E is wrong because playbooks cannot automatically install software.
Key principle: 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.
