- A
Configure SSL decryption to always bypass traffic to trusted domains.
Why wrong: SSL decryption should inspect encrypted traffic; bypassing trusted domains may allow threats.
- B
Configure the network to use the root DNS forwarder for all DNS queries.
Why wrong: Root DNS forwarders do not provide security filtering; Umbrella DNS resolvers are recommended.
- C
Enable IP-layer enforcement for all destinations.
IP-layer enforcement blocks malicious IPs at the network layer, providing comprehensive protection.
- D
Configure local security stack bypass for all internal IP ranges.
Why wrong: Local security stack bypass is not a standard practice and may reduce protection.
- E
Use Selective Proxy with PAC files to route traffic based on destination category.
Selective Proxy allows inspection of risky categories while bypassing trusted traffic, balancing security and performance.
Quick Answer
The answer is enabling IP-layer enforcement and using Selective Proxy with PAC files to route traffic based on destination category. IP-layer enforcement is correct because it provides a second layer of protection by inspecting and blocking traffic at the IP address level, ensuring that even if DNS-based blocking is bypassed via direct IP connections, malicious or policy-violating traffic is still dropped. Selective Proxy with PAC files complements this by allowing granular control over which traffic is proxied based on destination category, reducing latency for trusted sites while enforcing security policies on risky ones. On the Cisco SCOR 350-701 exam, this question tests your understanding of Cisco Umbrella’s layered defense model, often appearing as a scenario where DNS-only filtering fails. A common trap is assuming DNS blocking alone is sufficient, but the exam emphasizes that IP-layer enforcement catches direct IP connections that bypass DNS. Remember the memory tip: “DNS blocks the name, IP-layer blocks the game.”

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
Enable IP-layer enforcement for all destinations.
Option C is correct because enabling IP-layer enforcement in Cisco Umbrella ensures that all traffic to destinations that match a blocked category is dropped at the IP layer, even if DNS-based blocking is bypassed (e.g., via direct IP connections). This provides a second layer of protection by inspecting and blocking traffic based on the destination IP address, preventing users from circumventing DNS filtering by using IP addresses directly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that DNS-layer blocking is sufficient for full web security, but the trap here is that IP-layer enforcement is required to catch traffic that bypasses DNS, such as direct IP connections or non-DNS protocols.
Detailed technical explanation
How to think about this question
IP-layer enforcement works by integrating with the network's firewall or router (e.g., via Cisco AnyConnect or a virtual appliance) to intercept and block traffic based on the destination IP address, even if the DNS query was not forwarded to Umbrella. This is crucial in environments where users may hardcode IP addresses or use external DNS servers, as DNS-layer blocking alone cannot prevent such connections. In a real-world scenario, a user could bypass DNS filtering by using a direct IP address to a malicious site, but IP-layer enforcement would still block the connection at the network layer.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
