This SY0-701 practice question tests your understanding of security operations. 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.
Match each detection pattern to the most likely security issue. Each item has one best match.
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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.
Drag a concept onto its matching description — or click a concept then click the description.
Living-off-the-land or fileless malware execution
DNS tunneling or command-and-control beaconing
Password spraying or credential stuffing that succeeded
Compromised privileged credentials with persistence and post-exploitation activity
Correct answer & explanation
Repeated login failures indicate brute-force; Outbound connections to malicious IPs suggest C2; Large data transfers at odd hours indicate exfiltration; Random DNS subdomains are typical of tunneling; Conflicting ARP replies show spoofing; Multiple ICMP requests from many sources indicate DDoS.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SY0-701 NAT questions on configuration and troubleshooting.

Security Operations — This question tests Security Operations — Static NAT maps one inside address to one outside address..
Common exam trap: NAT rules depend on direction and matching traffic: NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Yes — watch for: "best", "most likely". Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
