- A
A distributed denial-of-service attack launched from a compromised internal host.
Why wrong: DDoS traffic is usually aimed at overwhelming a target with volume, not lateral administrative access and service creation.
- B
DNS tunneling used to exfiltrate data through allowed name-resolution traffic.
Why wrong: DNS tunneling would show unusual DNS patterns, not SMB spread, remote service creation, and privileged account use.
- C
ARP spoofing to redirect local traffic at the network layer.
Why wrong: ARP spoofing affects local segment traffic, but it does not explain the widespread host-to-host SMB activity and admin-share behavior.
- D
Lateral movement after credential compromise or endpoint takeover.
The workstation is behaving like an attacker foothold that is probing internal systems, using administrative shares, and attempting remote service creation. Those are strong signs of lateral movement after credentials or the device itself have been compromised. The privileged-account authentication attempts also suggest the attacker is trying to expand access and reach higher-value systems inside the environment.
SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. A key principle to apply: lateral movement expands an attacker's access from an initial foothold to other systems.. 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.
SIEM alerts show one workstation making SMB connections to 30 internal hosts within 10 minutes, followed by remote service creation and repeated access attempts to admin shares. The workstation also begins authenticating with several privileged accounts. What is the most likely activity?

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
Lateral movement after credential compromise or endpoint takeover.
The sequence of SMB connections to many internal hosts, followed by remote service creation and repeated access attempts to admin shares, combined with authentication using privileged accounts, is the classic pattern of lateral movement. This indicates the attacker has already compromised the workstation (endpoint takeover) or obtained valid credentials and is now using SMB and PsExec-like techniques to move laterally across the network, escalate privileges, and establish persistence.
Key principle: Lateral movement expands an attacker's access from an initial foothold to other systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A distributed denial-of-service attack launched from a compromised internal host.
Why it's wrong here
DDoS traffic is usually aimed at overwhelming a target with volume, not lateral administrative access and service creation.
- ✗
DNS tunneling used to exfiltrate data through allowed name-resolution traffic.
Why it's wrong here
DNS tunneling would show unusual DNS patterns, not SMB spread, remote service creation, and privileged account use.
- ✗
ARP spoofing to redirect local traffic at the network layer.
Why it's wrong here
ARP spoofing affects local segment traffic, but it does not explain the widespread host-to-host SMB activity and admin-share behavior.
- ✓
Lateral movement after credential compromise or endpoint takeover.
Why this is correct
The workstation is behaving like an attacker foothold that is probing internal systems, using administrative shares, and attempting remote service creation. Those are strong signs of lateral movement after credentials or the device itself have been compromised. The privileged-account authentication attempts also suggest the attacker is trying to expand access and reach higher-value systems inside the environment.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse lateral movement with a DDoS attack because of the many outbound connections, but the key differentiator is the use of admin shares and privileged account authentication, which are hallmarks of post-exploitation lateral movement, not volumetric attacks.
Trap categories for this question
Command / output trap
DNS tunneling would show unusual DNS patterns, not SMB spread, remote service creation, and privileged account use.
Detailed technical explanation
How to think about this question
Lateral movement often leverages Windows administrative tools like PsExec, which uses SMB (port 445) to copy and execute services on remote systems. The repeated access attempts to admin shares (ADMIN$, C$, IPC$) and authentication with privileged accounts indicate the attacker is using pass-the-hash or stolen credentials to move laterally, a technique commonly seen in ransomware and advanced persistent threat (APT) intrusions.
KKey Concepts to Remember
- Lateral movement expands an attacker's access from an initial foothold to other systems.
- Common techniques include credential theft, exploiting vulnerabilities, and using legitimate tools for malicious purposes.
- Indicators often include internal scanning, remote service creation, and access to administrative shares.
- Privileged account compromise is a key objective during lateral movement to gain broader control.
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
Lateral movement expands an attacker's access from an initial foothold to other systems.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Lateral movement expands an attacker's access from an initial foothold to other systems. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
