This CCSP practice question tests your understanding of cloud security operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 cloud security engineer is investigating a potential data breach in a cloud environment. The organization uses a cloud access security broker (CASB) and has deployed a security information and event management (SIEM) system. Which of the following are likely indicators that the CASB has detected unauthorized data exfiltration? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Anomalous spike in outbound traffic to an unknown IP address
CASBs are designed to detect anomalous data movements. An anomalous spike in outbound traffic to an unknown IP (A) and a large number of file downloads by a single user outside business hours (C) are strong indicators of exfiltration. Multiple failed logins (B) indicate brute force attempts, not exfiltration. Malware in email (D) is a malware indicator, not exfiltration. Firewall rule change (E) is a configuration change, not a direct exfiltration sign.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Anomalous spike in outbound traffic to an unknown IP address
Why this is correct
Unusual outbound traffic patterns can indicate data exfiltration.
Related concept
Static NAT maps one inside address to one outside address.
✗
A change in the configuration of a firewall rule
Why it's wrong here
Configuration changes may be part of an attack but are not a direct indicator of exfiltration.
✓
A large number of file downloads by a single user outside of business hours
Why this is correct
Unusual download volume can be a sign of data theft.
Related concept
Static NAT maps one inside address to one outside address.
✗
Multiple failed login attempts to a critical application
Why it's wrong here
This is more likely an authentication attack, not exfiltration.
✗
An alert for a known malware signature in an email attachment
Why it's wrong here
Malware detection is more relevant to email security, not cloud data loss.
Common exam traps
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.
Detailed technical explanation
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
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. 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
Got this wrong? Here's your next step.
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 CCSP NAT questions on configuration and troubleshooting.
