The answer is to configure the network's DNS forwarders to point to Umbrella's DNS resolvers. This deployment method is correct because it intercepts all DNS queries at the network level—typically on the DHCP server, router, or firewall—ensuring every device, including IoT, printers, and guest devices, is protected without any per-device configuration. On the Cisco SCOR 350-701 exam, this tests your understanding of network-level security integration versus agent-based or per-device approaches; a common trap is choosing a per-device agent method for “comprehensive” coverage, which misses unmanaged endpoints. The key concept is that DNS forwarder deployment provides the most comprehensive coverage by acting as a single chokepoint for all DNS traffic, making it ideal for environments with heterogeneous devices. Memory tip: think “Forwarder = Full coverage” because the network handles the filtering, not the endpoints.
350-701 Security Concepts Practice Question
This 350-701 practice question tests your understanding of security concepts. 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 is deploying Cisco Umbrella to protect against DNS-based threats. Which deployment method provides the most comprehensive coverage for all devices on the network without requiring per-device configuration?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure the network's DNS forwarders to point to Umbrella's DNS resolvers.
Option D is correct because configuring the network's DNS forwarders to point to Umbrella's DNS resolvers (typically on the organization's DHCP server or router) ensures that all DNS queries from any device on the network are automatically forwarded to Umbrella for filtering, without requiring any per-device configuration. This method provides comprehensive coverage for all devices, including those that cannot run agents (e.g., IoT devices, printers, guest devices), by intercepting DNS traffic at the network level.
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.
✗
Install the Umbrella roaming client on every endpoint.
Why it's wrong here
Requires per-device installation and may not cover all devices.
✗
Configure each device's DNS settings to use Umbrella's resolvers.
Why it's wrong here
Requires per-device configuration and may not be feasible for many devices.
✗
Deploy a PAC file that routes all traffic through a proxy with DNS filtering.
Why it's wrong here
Only covers devices that use the proxy and may not cover all traffic.
✓
Configure the network's DNS forwarders to point to Umbrella's DNS resolvers.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between endpoint-based and network-based deployment methods, and the trap here is that candidates assume the roaming client (Option A) provides the most comprehensive coverage, when in fact network-level DNS forwarding covers all devices without per-device configuration.
Detailed technical explanation
How to think about this question
When DNS forwarders are configured on a network's DHCP server or router, all DNS queries from clients are forwarded to Umbrella's resolvers (e.g., 208.67.222.222 and 208.67.220.220) via standard UDP port 53. Umbrella then applies policy-based filtering, blocking malicious domains before the client receives a response. This approach leverages the network's existing DHCP infrastructure to enforce DNS security without modifying endpoints, making it ideal for environments with BYOD or unmanaged devices.

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 practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
