- A
Place guest devices in a separate VLAN or subnet from employee devices.
A separate VLAN or subnet creates a distinct trust zone for guests, which helps keep their traffic isolated from internal corporate systems. It is a standard first step in secure network segmentation and makes later filtering easier.
- B
Add ACL or firewall rules that block guest traffic from reaching internal private networks.
Filtering traffic between the guest network and internal networks is essential because segmentation alone does not stop all communication. ACLs or firewall rules enforce the allowed paths and prevent guests from reaching file servers, printers, or other internal resources.
- C
Put guests on the same VLAN as employees and rely on stronger Wi-Fi passwords.
Why wrong: A stronger password does not provide isolation once a guest device is already inside the same broadcast domain. Sharing the employee VLAN increases exposure instead of reducing it.
- D
Disable SSID broadcast so guests cannot discover the network name.
Why wrong: Hiding the SSID is not a meaningful security boundary and does not stop a connected guest from reaching internal resources. It mainly affects convenience, not segmentation.
- E
Allow guest devices to use the same DHCP scope as internal endpoints.
Why wrong: Using the same addressing scope blurs the separation between guest and corporate devices. A secure design keeps the networks and routing controls distinct.
SY0-701 Security Architecture Practice Question
This SY0-701 practice question tests your understanding of security architecture. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company wants guest laptops on Wi-Fi to reach the internet, but not internal file servers or printers. Which two changes best support that design? Select two.
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
Place guest devices in a separate VLAN or subnet from employee devices.
Placing guest devices in a separate VLAN or subnet (Option A) is a fundamental network segmentation technique that isolates guest traffic from the internal corporate network at Layer 2 and Layer 3. This ensures that guest laptops cannot directly communicate with internal file servers or printers unless explicitly routed, and it allows the administrator to apply distinct security policies to the guest subnet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Put guests on the same VLAN as employees and rely on stronger Wi-Fi passwords.
Why it's wrong here
A stronger password does not provide isolation once a guest device is already inside the same broadcast domain. Sharing the employee VLAN increases exposure instead of reducing it.
- ✗
Disable SSID broadcast so guests cannot discover the network name.
Why it's wrong here
Hiding the SSID is not a meaningful security boundary and does not stop a connected guest from reaching internal resources. It mainly affects convenience, not segmentation.

Why it's wrong here
Using the same addressing scope blurs the separation between guest and corporate devices. A secure design keeps the networks and routing controls distinct.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse hiding the SSID (Option D) with actual access control, or they mistakenly believe that a strong Wi-Fi password (Option C) is sufficient to protect internal resources from authenticated guests, when in fact network segmentation via VLANs and ACLs is required.
Detailed technical explanation
How to think about this question
Under the hood, VLANs create separate broadcast domains at Layer 2, and inter-VLAN routing is typically controlled by a router or Layer 3 switch with ACLs. For example, a common design uses a guest VLAN (e.g., VLAN 100) with a dedicated subnet (e.g., 192.168.100.0/24) and an ACL on the Layer 3 interface that permits only HTTP/HTTPS and DNS traffic to the internet while denying all traffic to RFC 1918 private addresses (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). In a real-world scenario, a misconfigured ACL that allows guest traffic to the corporate subnet could expose sensitive file shares, making proper rule ordering and explicit deny statements critical.
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.
