- A
Place all servers in one VLAN and rely on host-based firewalls to block unwanted traffic.
Why wrong: This reduces some risk, but flat networks still make lateral movement easier if one host is compromised.
- B
Create separate DMZ, application, and database zones with default-deny east-west rules and use a jump host for administration.
This design limits exposure at each layer, prevents direct user-to-database access, and gives administrators a controlled management path.
- C
Put the database in the DMZ so the web tier can connect to it without extra firewall rules.
Why wrong: Placing the database in a more exposed zone increases risk and conflicts with least-exposure principles.
- D
Expose the application tier to the Internet and use NAT to hide the database subnet.
Why wrong: NAT does not provide meaningful segmentation, and exposing the application tier broadens the attack surface unnecessarily.
SY0-701 Security Architecture Practice Question
This SY0-701 practice question tests your understanding of security architecture. 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.
An online retailer is moving its public web app, internal API, and database into separate zones. Public users must reach only the web tier. The web tier must contact the app tier, and only the app tier may query the database. Admins should manage all servers from a hardened jump host. Which design best meets these goals and minimizes lateral movement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create separate DMZ, application, and database zones with default-deny east-west rules and use a jump host for administration.
Option B is correct because it implements a multi-tier network architecture with separate DMZ, application, and database zones, enforcing default-deny east-west traffic rules. This ensures that public users can only reach the web tier, the web tier can only communicate with the app tier, and only the app tier can query the database, while all administrative access is funneled through a hardened jump host, which minimizes lateral movement by restricting inter-zone traffic to only what is explicitly required.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place all servers in one VLAN and rely on host-based firewalls to block unwanted traffic.
Why it's wrong here
This reduces some risk, but flat networks still make lateral movement easier if one host is compromised.
- ✓
Create separate DMZ, application, and database zones with default-deny east-west rules and use a jump host for administration.
Why this is correct
This design limits exposure at each layer, prevents direct user-to-database access, and gives administrators a controlled management path.
Clue confirmation
The clue word "best" in the question point toward this answer.

- ✗

Why it's wrong here
Placing the database in a more exposed zone increases risk and conflicts with least-exposure principles.
- ✗
Expose the application tier to the Internet and use NAT to hide the database subnet.
Why it's wrong here
NAT does not provide meaningful segmentation, and exposing the application tier broadens the attack surface unnecessarily.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume placing the database in the DMZ simplifies connectivity, but this violates the principle of defense in depth by removing network segmentation between the web tier and sensitive data storage.
Detailed technical explanation
How to think about this question
In a multi-tier architecture, east-west traffic is controlled using stateful firewalls or security groups that inspect packets at Layers 3-4 (and optionally Layer 7), with default-deny rules that only permit specific protocols (e.g., HTTPS on TCP 443 from web to app, SQL on TCP 1433 from app to database). A jump host (bastion host) is typically placed in a management zone with strict access controls, such as SSH key-based authentication and session logging, to prevent direct administrative access to production servers, which would otherwise create additional lateral movement paths.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
