350-701 Practice Question: A company has a hybrid cloud environment with…
A company has a hybrid cloud environment with workloads in AWS and Azure, and an on-premises data center. They use Cisco Tetration for micro-segmentation and Cisco CloudCenter for orchestration. Recently, they deployed a new multi-tier application in AWS: a web tier, an application tier, and a database tier, all across multiple Availability Zones. After deployment, the application is unreachable. The security team reviews Tetration policies and finds that a policy is in place to allow traffic between tiers, but the web tier cannot communicate with the application tier. The Tetration agent status shows all agents are healthy. The administrator checks the AWS security groups and notices that the web tier's security group allows inbound HTTP from 0.0.0.0/0, but the application tier's security group does not allow inbound traffic from the web tier's subnet. The application tier's security group only allows inbound traffic from the on-premises CIDR block in error. The network team requests a fix that does not impact other ongoing audits. What should the administrator do?
⚠ Common exam trap
Cisco often tests the misconception that Tetration's micro-segmentation policies can override or bypass cloud-native security groups, when in fact both layers must be correctly configured for traffic to flow.

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
✓
Update the AWS security group for the application tier to allow inbound traffic from the web tier's subnet.
The root cause is that the AWS security group for the application tier is misconfigured to only allow inbound traffic from the on-premises CIDR block, rather than from the web tier's subnet. Cisco Tetration enforces micro-segmentation policies at the host level via agents, but it does not override or bypass native cloud security groups; both layers must permit the traffic. Updating the security group to allow inbound traffic from the web tier's subnet resolves the connectivity issue without affecting other audits, as it is a targeted, non-disruptive change.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Redeploy the application using Cisco CloudCenter to ensure proper security group association.
Why it's wrong here
Incorrect: This is a time-consuming workaround and may introduce additional issues.
- ✗
Configure Tetration to use 'full enforcement' mode for all policies, which overrides AWS security groups.
Why it's wrong here
Incorrect: Tetration does not automatically override cloud-native security groups; they coexist.
- ✓
Update the AWS security group for the application tier to allow inbound traffic from the web tier's subnet.
Why this is correct
Correct: This directly fixes the misconfigured security group blocking traffic.
- ✗
Remove the Tetration policy for the application tier to allow all traffic.
Why it's wrong here
Incorrect: This removes micro-segmentation needed for security.
