- A
Bridge the VM directly to the physical network adapter
Why wrong: Bridging gives the VM its own IP on the corporate network, exposing it to all network traffic and defeating isolation.
- B
Use a virtual switch set to host-only mode and configure port forwarding for HTTPS
Host-only mode isolates the VM from the physical network, and port forwarding allows only HTTPS traffic from the host to the VM, meeting the security requirement.
- C
Attach the VM to a NAT network without any port forwarding
Why wrong: NAT without forwarding would allow the VM to access the internet but not receive inbound HTTPS traffic from the corporate network.
- D
Assign the VM an IP from the corporate DHCP scope
Why wrong: This would place the VM directly on the corporate network, violating the isolation requirement.
Quick Answer
The correct answer is to use a virtual switch set to host-only mode and configure port forwarding for HTTPS. This configuration isolates the VM from the corporate network by restricting communication to the host machine only, while a port forwarding rule specifically directs inbound HTTPS traffic from the host to the VM’s web server. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of virtual networking security and the distinction between host-only, NAT, and bridged modes. A common trap is choosing bridged mode, which would expose the VM directly to the corporate LAN, defeating the isolation requirement. Remember that host-only networking creates a private virtual switch between the host and VM, and port forwarding acts as a controlled gateway for specific traffic. A helpful memory tip: “Host-only hides, port forward guides”—the host-only switch hides the VM from the network, while port forwarding guides only the allowed traffic through.
220-1102 Virtualization and Cloud Technologies Practice Question
This 220-1202 practice question tests your understanding of virtualization and cloud technologies. 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 technician is deploying a new virtual machine on a Type 1 hypervisor. The VM will run a Linux web server and needs to be isolated from the corporate network except for HTTPS traffic. Which networking configuration should the technician implement?

Correct answer & explanation
Use a virtual switch set to host-only mode and configure port forwarding for HTTPS
A virtual switch with a host-only or internal network isolates the VM from the corporate LAN, while port forwarding or a NAT rule allows specific inbound HTTPS traffic. This ensures the VM is not directly exposed to the broader network. The question tests understanding of virtual networking and security isolation.
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.
- ✗
Bridge the VM directly to the physical network adapter
Why it's wrong here
Bridging gives the VM its own IP on the corporate network, exposing it to all network traffic and defeating isolation.
- ✓
Use a virtual switch set to host-only mode and configure port forwarding for HTTPS
- ✗
Attach the VM to a NAT network without any port forwarding
- ✗
Assign the VM an IP from the corporate DHCP scope
Why it's wrong here
This would place the VM directly on the corporate network, violating the isolation requirement.
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.
