The correct answer is misconfiguration of cloud resources leading to data exposure and insecure APIs, as both represent common security concerns specific to a public cloud infrastructure. Misconfiguration, such as leaving storage buckets publicly accessible, directly exposes sensitive data, while insecure APIs create a broad attack surface for unauthorized programmatic access. On the CompTIA Cloud+ CV0-004 exam, this question tests your understanding of the shared responsibility model, where the provider handles physical security but you must secure configurations and APIs. A common trap is confusing provider-managed risks like hypervisor vulnerabilities or packet sniffing with tenant-controlled risks; remember that in public clouds, physical security and hypervisor patching fall to the provider, not you. Memory tip: think "API and Config" as the two C's of cloud exposure—Control your APIs and Configuration to prevent leaks.
CV0-004 Security Practice Question
This CV0-004 practice question tests your understanding of security. 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.
Which TWO of the following are common security concerns specific to a public cloud infrastructure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Exposure of insecure application programming interfaces (APIs).
Options A and C are correct. Insecure APIs are a top cloud security concern because they allow programmatic access, and misconfigured storage can lead to data exposure. Option B is wrong because physical security is the provider's responsibility. Option D is wrong because packet sniffing is unlikely in multitenant clouds. Option E is wrong because hypervisor vulnerabilities are rare and quickly patched.
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.
✓
Exposure of insecure application programming interfaces (APIs).
Why this is correct
APIs are often targeted by attackers if not properly secured.
Related concept
Static NAT maps one inside address to one outside address.
✗
Physical theft of servers from data centers.
Why it's wrong here
Physical security is managed by the cloud provider.
✗
Packet sniffing on the provider's internal network.
Why it's wrong here
Cloud providers isolate tenant traffic; sniffing is not practical.
✓
Misconfiguration of cloud resources leading to data exposure.
Why this is correct
Misconfigured storage or permissions are frequent issues.
Related concept
Static NAT maps one inside address to one outside address.
✗
Hypervisor-level malware.
Why it's wrong here
Hypervisor attacks are rare and not a common concern.
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.
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 CV0-004 NAT questions on configuration and troubleshooting.
Security — This question tests Security — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Exposure of insecure application programming interfaces (APIs). — Options A and C are correct. Insecure APIs are a top cloud security concern because they allow programmatic access, and misconfigured storage can lead to data exposure. Option B is wrong because physical security is the provider's responsibility. Option D is wrong because packet sniffing is unlikely in multitenant clouds. Option E is wrong because hypervisor vulnerabilities are rare and quickly patched.
What should I do if I get this CV0-004 question wrong?
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 CV0-004 NAT questions on configuration and troubleshooting.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.

Variation 1. Which TWO of the following are common vulnerabilities in cloud environments that can lead to unauthorized access? Select two.
medium
A.Enabling automatic patching
✓ B.Lack of encryption for data in transit
C.Using multi-factor authentication
D.Properly scoped IAM roles
✓ E.Misconfigured security groups allowing overly permissive inbound rules
Why B: Options A and D are correct because misconfigured security groups and lack of encryption in transit are common vulnerabilities. B, C, and E are security best practices.
