The correct answer is to enable the DNS Policy feature within the Umbrella roaming client. This configuration prevents a DNS policy bypass by intercepting all DNS requests at the operating system level and forcibly redirecting them to Umbrella’s resolvers, even when a user manually sets a third-party DNS server like Google (8.8.8.8). On the Cisco SCOR 350-701 exam, this scenario tests your understanding of endpoint-based enforcement versus network-layer controls; a common trap is assuming a firewall rule or DHCP option alone can block roaming client bypasses. Remember that the Umbrella roaming client’s DNS Policy is a software-based, host-level solution that overrides local DNS settings, making it essential for remote users outside the corporate network. Memory tip: think “DNS Policy = Local Force” — the client forces DNS traffic to Umbrella regardless of the user’s manual configuration.
350-701 Content Security Practice Question
This 350-701 practice question tests your understanding of content security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 enforce security policies for remote users. They want to ensure that DNS requests from roaming clients are routed through Umbrella's DNS resolvers. However, some users are bypassing Umbrella by using third-party DNS servers like Google (8.8.8.8). Which configuration should be applied to prevent this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable DNS Policy in the Umbrella roaming client
Option D is correct because the Umbrella roaming client's DNS Policy feature forces all DNS traffic from the endpoint to use Umbrella's DNS resolvers, even if the user manually configures a third-party DNS server like Google (8.8.8.8). This is achieved by intercepting DNS requests at the OS level and redirecting them to the Umbrella resolvers, effectively preventing bypass attempts without relying on network-level blocks.
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.
✗
Configure Content Filtering to block Google DNS
Why it's wrong here
Content filtering works at the URL level, not DNS.
✗
Add a firewall rule on each client to block port 53 to all but Umbrella
Why it's wrong here
This is not centrally managed and may interfere with legitimate traffic.
✗
Enable IP Layer Enforcement in the Umbrella dashboard
Why it's wrong here
IP Layer Enforcement blocks public IPs but does not stop DNS requests to third-party servers.
✓
Enable DNS Policy in the Umbrella roaming client
Why this is correct
This forces all DNS requests through Umbrella and blocks alternative DNS servers.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between network-level enforcement (like IP Layer Enforcement) and endpoint-level enforcement (like DNS Policy in the roaming client), leading candidates to mistakenly choose IP Layer Enforcement because it sounds like a global solution, but it fails for roaming clients not connected to the corporate network.
Detailed technical explanation
How to think about this question
The Umbrella roaming client uses a virtual network adapter or a DNS proxy to intercept all DNS queries at the operating system level, overriding the system's DNS settings. When DNS Policy is enabled, the client enforces that only Umbrella's DNS resolvers (e.g., 208.67.222.222 and 208.67.220.220) are used, even if the user manually configures a different DNS server; this is done by redirecting the DNS traffic to a local proxy that forwards it to Umbrella. In a real-world scenario, this ensures that roaming users on public Wi-Fi or home networks remain protected by Umbrella's security policies, such as blocking malicious domains, regardless of their DNS configuration.

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.

Variation 1. A company uses Cisco Umbrella to protect its remote users. The security team notices that some users are able to bypass Umbrella by using a different DNS resolver. Which deployment method ensures that all DNS traffic is forced through Umbrella?
easy
A.Deploy the Umbrella virtual appliance in the data center.
B.Use BGP to redirect traffic to Umbrella.
✓ C.Install the Umbrella roaming client on all endpoints.
D.Configure Active Directory integration.
Why C: The Cisco Umbrella roaming client (C) is the correct deployment method because it installs a local agent on each endpoint that intercepts all DNS queries at the operating system level, regardless of the DNS resolver configured in the network settings. This ensures that all DNS traffic is forced through Umbrella's cloud-based security platform, preventing users from bypassing protection by manually changing their DNS resolver to a non-Umbrella server.
