- A
Run a full antivirus scan on the user's workstation
Why wrong: Running an antivirus scan is not the first step because the incident is a credential theft via phishing, not a malware infection. While the system may have been compromised, containment of the credentials is more urgent.
- B
Reset the user's password and force re-authentication
Why wrong: Resetting the password is a corrective action but doing so before containing the attacker's access could alert them, allowing them to pivot or destroy evidence. Containment should come first.
- C
Disable the user's account and block the compromised system from the network
This is the correct first step. Disabling the account and isolating the system immediately prevents the attacker from using the stolen credentials to access resources, move laterally, or exfiltrate data.
- D
Contact law enforcement and report the phishing site
Why wrong: Contacting law enforcement is important but should be done after internal containment and data preservation. Immediate containment takes priority over external reporting.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 receives an alert that a user clicked a link in a phishing email and entered their corporate credentials on a fake login page. Which of the following should the analyst do FIRST to minimize further damage?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"first"Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
Disable the user's account and block the compromised system from the network
Option C is correct because immediately disabling the user's account and blocking the compromised system from the network stops the attacker from using the stolen credentials to authenticate to corporate resources, such as email, VPN, or file shares. This containment step is the highest priority in incident response to prevent lateral movement and further compromise, as the attacker already has valid credentials and could be actively using them.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Run a full antivirus scan on the user's workstation
Why it's wrong here
Running an antivirus scan is not the first step because the incident is a credential theft via phishing, not a malware infection. While the system may have been compromised, containment of the credentials is more urgent.
When this WOULD be correct
This would be correct if the question stated that the user's credentials were already reset and the account was secured, and the next step is to ensure the workstation is free from malware that could exfiltrate data or provide persistent access.
- ✗
Reset the user's password and force re-authentication
Why it's wrong here
Resetting the password is a corrective action but doing so before containing the attacker's access could alert them, allowing them to pivot or destroy evidence. Containment should come first.
When this WOULD be correct
This would be correct if the question stated that the user's account was not yet compromised (e.g., the user reported the phishing email before entering credentials) and the goal is to proactively protect the account from potential misuse.
- ✓
Disable the user's account and block the compromised system from the network
Why this is correct
This is the correct first step. Disabling the account and isolating the system immediately prevents the attacker from using the stolen credentials to access resources, move laterally, or exfiltrate data.
Clue confirmation
The clue words "first", "minimum / minimize" in the question point toward this answer.

- ✗
Contact law enforcement and report the phishing site
Why it's wrong here
Contacting law enforcement is important but should be done after internal containment and data preservation. Immediate containment takes priority over external reporting.
When this WOULD be correct
This option would be correct if the question asked: 'After containing the incident and preserving evidence, which of the following should the analyst do to assist in the investigation and prosecution of the attacker?'
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SY0-701 exam frequently reuses these exact scenarios with slightly different constraints.
✓Disable the user's account and block the compromised system from the networkCorrect answer▾
Why this is correct
This is the correct first step. Disabling the account and isolating the system immediately prevents the attacker from using the stolen credentials to access resources, move laterally, or exfiltrate data.
✗Run a full antivirus scan on the user's workstationWrong answer — click to see why▾
Why this is wrong here
Running a full antivirus scan is a reactive step that does not immediately prevent further unauthorized access or credential misuse. The priority is to contain the breach by disabling the account and isolating the system.
★ When this WOULD be the correct answer
This would be correct if the question stated that the user's credentials were already reset and the account was secured, and the next step is to ensure the workstation is free from malware that could exfiltrate data or provide persistent access.
Why candidates choose this
Candidates may think that malware is the primary threat from phishing and that scanning will remove any backdoors, overlooking the immediate need to stop credential abuse.
✗Reset the user's password and force re-authenticationWrong answer — click to see why▾
Why this is wrong here
Resetting the password and forcing re-authentication does not immediately isolate the compromised system or prevent the attacker from using the stolen credentials to access other resources before the password change takes effect.
★ When this WOULD be the correct answer
This would be correct if the question stated that the user's account was not yet compromised (e.g., the user reported the phishing email before entering credentials) and the goal is to proactively protect the account from potential misuse.
Why candidates choose this
Candidates often think that changing the password is the fastest way to revoke access, but they overlook the need to first disable the account and block the system to stop ongoing lateral movement or data exfiltration.
✗Contact law enforcement and report the phishing siteWrong answer — click to see why▾
Why this is wrong here
Contacting law enforcement is not the first priority; immediate containment actions like disabling the account and blocking the system are needed to prevent further credential misuse.
★ When this WOULD be the correct answer
This option would be correct if the question asked: 'After containing the incident and preserving evidence, which of the following should the analyst do to assist in the investigation and prosecution of the attacker?'
Why candidates choose this
Candidates may think reporting the phishing site to law enforcement is a critical early step, but they overlook the need for immediate containment to stop ongoing damage.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose to reset the password first (Option B) because it seems like a direct fix, but they fail to recognize that the compromised system itself may be under attacker control, and without network isolation, the attacker could still pivot or use other stolen credentials.
Detailed technical explanation
How to think about this question
In a credential theft incident, the attacker likely has the user's password and may be using it to authenticate via protocols like Kerberos or NTLM to access domain resources. Disabling the account invalidates the Kerberos TGT and NTLM hashes, while blocking the system at the network level (e.g., via 802.1X or switch port shutdown) prevents any further network-based attacks from that endpoint, even if the attacker has other tools or backdoors. This aligns with the NIST SP 800-61 incident response framework, which prioritizes containment over eradication or recovery.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
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
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
