The answer is data classification and encryption of customer data. This is correct because the shared responsibility model customer responsibility centers on securing anything the customer creates or controls within the cloud, such as data content, access policies, and account configurations, while the cloud provider handles the physical and operational security of the underlying infrastructure. On the Certified Ethical Hacker CEH exam, this concept tests your understanding of where the attacker’s focus shifts—since the provider secures the hardware, the customer’s data and its classification become the primary attack surface. A common trap is confusing network or hypervisor security with customer duties; remember that the provider secures the cloud, but the customer secures what is in the cloud. Memory tip: “Your data, your duty—classify and encrypt before the cloud can protect.”
CEH Practice Question: Advanced Topics: Wireless, Cloud, IoT, Cryptography

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.
In the shared responsibility model for cloud computing, which of the following is typically the responsibility of the customer?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data classification and encryption of customer data
The customer is responsible for data classification and account management, while the provider secures the physical infrastructure.
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.
✗
Physical security of data centers
Why it's wrong here
Physical security is the provider's responsibility.
✗
Patch management of the virtualization platform
Why it's wrong here
Patches on the virtualization platform are the provider's responsibility.
✓
Data classification and encryption of customer data
Why this is correct
Customers are responsible for classifying and encrypting their own data.
Related concept
Static NAT maps one inside address to one outside address.
The provider secures the underlying network infrastructure.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
