The correct answers are that a VPN allows access to internal resources and provides encrypted communication for remote employees. A VPN creates a secure, encrypted tunnel between a remote worker’s device and the corporate network, ensuring that sensitive data transmitted over public internet connections remains confidential and tamper-proof. This encryption protects against eavesdropping on Wi-Fi hotspots, while the tunnel grants the employee the same access to internal servers, file shares, and applications as if they were physically in the office. On the CompTIA ITF+ FC0-U61 exam, this question tests your understanding of VPN fundamentals under the “Networking” domain, and a common trap is confusing encryption overhead with a bandwidth increase—VPNs actually reduce bandwidth due to that overhead. Another trap is thinking a VPN replaces antivirus or reduces hardware costs, which it does not. For a memory tip, remember “E-A-T”: Encryption and Access are the Two key VPN advantages for remote employees.
FC0-U61 Infrastructure Practice Question
This FC0-U61 practice question tests your understanding of infrastructure. 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.
Which TWO of the following are advantages of using a virtual private network (VPN) for remote employees?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Provides encrypted communication
Options B and C are correct. VPNs provide encrypted communication (B) and allow access to internal resources (C). Option A is incorrect because VPNs typically reduce bandwidth due to encryption overhead. Option D is incorrect because VPNs do not directly reduce hardware costs. Option E is incorrect because a VPN does not eliminate the need for antivirus software.
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.
✗
Eliminates need for antivirus software
Why it's wrong here
VPNs do not protect against malware; antivirus is still needed.
✓
Provides encrypted communication
Why this is correct
VPNs encrypt data to ensure confidentiality.
Related concept
Static NAT maps one inside address to one outside address.
✓
Allows access to internal resources
Why this is correct
VPNs create a secure tunnel to the internal network.
Related concept
Static NAT maps one inside address to one outside address.
✗
Reduces hardware costs
Why it's wrong here
VPNs may require additional hardware or licensing.
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 FC0-U61 NAT questions on configuration and troubleshooting.
