Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engineers (ENSDENG) Exam Practice Test
This practice page focuses on enterprise network design and access control across Cisco Software-Defined Access (SD-Access), Cisco SD-WAN, and Cisco Identity Services Engine (ISE). The question bank samples how fabric connectivity, application-aware traffic steering, endpoint authentication, and authorization decisions fit into network engineering scenarios.
Exam overview
About the Cisco Enterprise Networks SDA, SDWAN and ISE Exam for System Engin… Exam
Engineering decisions in these areas connect policy intent to network behavior. SD-Access scenarios involve fabric roles such as border nodes and resilient paths to external networks. SD-WAN scenarios examine application-aware policies, transport selection, and measured path characteristics such as latency. ISE scenarios involve EAP-TLS authentication, endpoint context, authorization profiles, VLAN assignment, and downloadable ACLs returned to network access devices. Some questions also address group-based access control and how access switches can preserve locally configured authentication behavior during a temporary ISE connectivity loss. Use these scenarios to practice identifying which component or policy mechanism fits a stated operational requirement, while distinguishing authentication evidence from authorization results.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
An organization wants a Cisco ISE authorization result to place a successfully authenticated endpoint into a designated access VLAN. Which type of information can ISE return to the network access device to support this?
Show answer
Correct answer: AISE can return authorization attributes in a RADIUS response, including attributes used by supported network devices for dynamic VLAN assignment. OMP routes, VXLAN identifiers, and certificate lists serve different purposes.
In a Cisco SD-Access deployment, what is the purpose of a fabric border node?
Show answer
Correct answer: AA fabric border node provides connectivity between the SD-Access fabric and external networks, handling traffic that enters or leaves the fabric. DHCP services, endpoint authentication, and wireless radio management are separate functions.
A Cisco ISE administrator wants to distinguish a managed corporate laptop from an unmanaged endpoint during policy evaluation. Which input can provide useful context when it is available and reliable?
Show answer
Correct answer: AISE policies can use endpoint identity and supported posture or compliance context to make differentiated access decisions. Physical equipment appearance and unrelated path details do not establish endpoint trust state.
A Cisco SD-WAN operator needs to ensure that a particular application uses a specified transport circuit, regardless of the general route preference. Which policy type is most appropriate for expressing application-aware traffic steering?
Show answer
Correct answer: AApplication-aware routing policies can classify application traffic and influence path selection using configured requirements and transport characteristics. The other choices do not provide application-specific WAN path steering.
An enterprise is designing redundant SD-Access fabric connectivity to an external data center. Which design choice most directly avoids making a single border node a point of failure?
Show answer
Correct answer: AMultiple border nodes can provide redundant paths between the fabric and external networks. Routing and resiliency must be designed so that loss of one border node does not eliminate external connectivity.
What is the purpose of certificate-based EAP-TLS authentication in an enterprise network?
Show answer
Correct answer: AEAP-TLS uses certificates and TLS to authenticate the client and authentication server, commonly providing mutual authentication. Authorization remains a separate policy decision after authentication.
A Cisco SD-WAN administrator wants to steer selected application traffic onto the path with the lowest measured latency while respecting configured policy. Which capability is most directly relevant?
Show answer
Correct answer: AApplication-aware routing uses measured transport characteristics, such as latency, loss, and jitter, to select paths in accordance with configured policy. The other protocols serve unrelated network functions.
How to use this practice test
The free US Practice Tests bank contains 50 questions for this exam. Each practice session presents up to 20 questions selected at random, so different sessions can sample different scenarios. Results appear after the session; use them to identify whether you need more work on fabric roles, SD-WAN steering, or ISE authentication and authorization behavior.
Preparation tips
- Trace an endpoint access flow from EAP-TLS authentication through ISE policy evaluation to the authorization attributes sent to a switch, including VLAN or downloadable ACL outcomes.
- Compare SD-Access fabric node roles and sketch redundant border-node paths to an external data center; identify where a single-node dependency could arise.
- For SD-WAN scenarios, distinguish application-aware traffic steering from general route preference, and relate latency measurements to policy-based path selection.
- Review how endpoint identity or posture context can inform ISE policy, and separate that context from the authorization profile that applies session access.
- Examine how network access devices handle authentication during ISE connectivity loss, distinguishing locally available behavior from centralized policy decisions.
