20+ practice questions focused on Cisco DNA Center — one of the most tested topics on the ENCOR 350-401 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cisco DNA Center PracticeA network engineer is deploying Cisco DNA Center in a large campus network with 5000+ devices. After initial setup, the engineer notices that the Assurance module is not receiving telemetry data from many access switches. The switches are running IOS-XE 16.12 and are reachable via SNMP. What is the most likely cause of this issue?
Explanation: Cisco DNA Center Assurance relies on telemetry data collected via NETCONF/YANG or gRPC, not just SNMP. If the switches are not configured for telemetry, Assurance will not receive the necessary data. SNMP is used for inventory and basic monitoring, but not for the rich telemetry required by Assurance.
A network engineer is using Cisco DNA Center to automate the deployment of a new VLAN across multiple access switches. The engineer creates a new network profile with the VLAN definition and assigns it to a site. However, after provisioning, the VLAN is not created on any of the switches. The engineer verifies that the devices are in the Inventory and are reachable. What is the most likely cause?
Explanation: In Cisco DNA Center, network profiles are used to define settings, but they must be applied to a site and then the devices must be provisioned with that site's settings. If the engineer only created the profile and assigned it to a site, but did not run the provisioning workflow (which pushes the configuration to devices), the VLAN will not be created.
A network engineer is troubleshooting a wireless connectivity issue in a campus network managed by Cisco DNA Center. The Assurance module shows that several access points have high client association failures. The engineer checks the wireless controller configuration and finds that the APs are registered and functional. What is the most likely cause of the association failures?
Explanation: Cisco DNA Center Assurance can correlate client association failures with RF interference, authentication issues, or configuration mismatches. Since the APs are registered and functional, the issue is likely related to RF interference or signal quality. DNA Center's Assurance can analyze client association events and highlight RF issues as a common cause.
A network engineer is deploying Cisco DNA Center in a brownfield network. The engineer wants to use DNA Center to automate the configuration of QoS policies across all access switches. After discovering the devices and adding them to Inventory, the engineer creates a QoS policy and assigns it to a site. However, when attempting to provision, DNA Center reports that the devices are in 'Compliance Error' state. What is the most likely reason?
Explanation: In brownfield deployments, devices may have existing configurations that conflict with the intended policies. DNA Center performs a compliance check before provisioning. If the current device configuration does not match the intended configuration (e.g., existing QoS settings), DNA Center reports a compliance error. The engineer must either update the device configuration to match the intent or modify the intent to accommodate the existing configuration.
A network engineer is using Cisco DNA Center to manage a network with multiple sites. The engineer wants to ensure that all devices at a remote site have the same NTP server configuration. The engineer creates a network profile with the NTP settings and assigns it to the site. After provisioning, the engineer checks one of the switches and finds that the NTP configuration is missing. What should the engineer check first?
Explanation: In Cisco DNA Center, network profiles are applied to sites, but devices must be assigned to the correct site hierarchy. If a device is not assigned to the site where the profile is applied, it will not receive the configuration. The engineer should verify that the device is in the correct site within DNA Center's hierarchy.

2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Cisco DNA Center questions on the 350-401 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Cisco DNA Center is tested as part of the ENCOR 350-401 blueprint. Practicing with targeted Cisco DNA Center questions ensures you can handle any format or difficulty that appears.
