Prevent Umbrella Bypass: Enable DNS Policy on Roaming Clients
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?
Quick Answer
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.
⚠ Common exam trap
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.

Correct answer & explanation
✓
Enable DNS Policy in the Umbrella roaming client
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.
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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
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.
