Exhibit
Cloud deployment summary: - Public API runs on an IaaS virtual machine - Database runs on a managed PaaS service - Object storage holds user uploads - Provider responsibility: datacenter, hardware, hypervisor, managed DB platform - Customer responsibility: guest OS, IAM, network rules, application code Finding: TCP/22 on the API VM is reachable from 0.0.0.0/0.
Based on the exhibit, what is the best security change to address the exposed management access on the cloud VM?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Ask the provider to patch the guest operating system on the VM.
The cloud provider does not manage the guest operating system in an IaaS virtual machine.
B
Distractor review
Move SSH to a public IP on the VM so administrators can reach it more easily.
Making SSH more directly reachable increases exposure and does not reduce the attack surface.
C
Best answer
Restrict SSH through a bastion host or VPN and remove direct internet access to the VM.
In IaaS, the customer owns network controls. A bastion or VPN keeps management traffic private and limited to approved admins.
D
Distractor review
Enable object storage versioning to protect the VM from unauthorized logins.
Object storage versioning helps with file recovery, not with controlling administrative access to a server.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Restrict SSH through a bastion host or VPN and remove direct internet access to the VM. — The customer is responsible for guest OS access controls and network rules in an IaaS environment. Because SSH is exposed to the internet, the best corrective action is to remove direct exposure and require administration through a bastion host or VPN. That reduces the attack surface, supports logging, and keeps administrative traffic off the public internet. The provider is not the party responsible for locking down the VM guest OS or its access path. Why others are wrong: Option A assigns a customer responsibility to the provider. Option B increases exposure and makes brute-force and credential attacks easier. Option D addresses storage resilience, but it does nothing to secure remote administration of the virtual machine.
