A company is building a public web app with three tiers. Internet users should reach only the web tier, and the app tier should never be reachable from the internet. Which two network design choices support this goal? Select two.
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
Best answer
Place the web server in a DMZ or public-facing zone.
A DMZ is the standard place for internet-facing services because it creates a controlled boundary between public traffic and internal systems. It lets the web tier accept external requests without exposing deeper resources.
B
Distractor review
Allow inbound traffic from the internet directly to the application servers.
Direct internet access to the application servers defeats the purpose of a tiered design. It exposes the middle tier unnecessarily and makes it harder to control attacks.
C
Best answer
Restrict the application tier so only the web tier can initiate connections to it.
Limiting app-tier access to the web tier enforces the intended trust boundary. This is a classic segmentation rule for multi-tier applications and reduces the number of systems that can talk to the application layer.
D
Distractor review
Put the database on the guest Wi-Fi VLAN.
Guest wireless is untrusted and unsuitable for sensitive back-end systems. Placing a database there would be a severe architecture error rather than a security control.
E
Distractor review
Use the same flat network for all three tiers.
A flat network eliminates separation and makes lateral movement easier. It is the opposite of a secure zone-based design for public applications.
Common exam trap
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Technical deep dive
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.

Question 2
An employee reports a ransomware note on a file server. The server is still powered on, shares are still being accessed, and management wants service restored as quickly as possible. What should the incident response team do first?
Question 3
An employee reports a ransomware note on a finance laptop. The laptop is still powered on, connected to Wi-Fi, and the user says they were just working in a spreadsheet. Management wants the fastest safe response that also preserves evidence. What should the responder do first?

Question 6
A branch office uses a flat LAN, and a compromise on one user workstation could spread quickly to finance systems.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: Place the web server in a DMZ or public-facing zone. — The correct design places the web tier in a DMZ and limits access to the application tier so only the web tier can initiate connections. That arrangement matches a standard three-tier security model: public users reach only the front-end, while internal layers remain hidden behind controlled boundaries. Segmentation reduces exposure and makes policy enforcement much clearer. Why others are wrong: Letting the internet talk to the app servers or using one flat network removes the protection that zoning is supposed to provide. The database should also remain in a restricted internal zone, not on guest wireless. The best pair preserves trust boundaries between tiers and keeps public access at the edge.
