This SC-200 practice question tests your understanding of respond to security incidents. 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.
A security analyst in your SOC receives an alert from Microsoft Defender for Cloud Apps indicating that a user downloaded a large number of files from SharePoint in a short time. What is the most likely classification of this activity?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Ransomware
Why wrong: No encryption or ransom note mentioned.
Lateral movement
Why wrong: No evidence of moving to other systems.
Data exfiltration
Downloading many files suggests theft of data.
Privilege escalation
Why wrong: No indication of permission changes.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Data exfiltration
Option A is correct because this behavior is indicative of data exfiltration. Option B is wrong because privilege escalation involves gaining higher permissions. Option C is wrong because ransomware would encrypt files. Option D is wrong because lateral movement involves moving between systems.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Ransomware
Why it's wrong here
No encryption or ransom note mentioned.
Lateral movement
Why it's wrong here
No evidence of moving to other systems.
Data exfiltration
Why this is correct
Downloading many files suggests theft of data.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Authentication checks who the user is.
Privilege escalation
Why it's wrong here
No indication of permission changes.
Common exam traps
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related SC-200 questions on access control and AAA configuration.
