Designing Cisco Enterprise Networks (ENSLD) Questions 116–120 (page: 25)

Updated On: 10-Feb-2026

An engineer working for a service provider with an employee ID: 4604:68:004 prepared several designs for a traditional campus network. The design must allow the deployment of the same VLAN to any switch at the access layer and must support:
-fast convergence
-high availability
-resilience

Which design must be selected?





Answer(s): D



Refer to the exhibit.



A Cisco Catalyst switch is configured to allow only one MAC address to be learned manually on interface gig0/2. Which command must be run to dynamically learn the devices that are connected to the switch port?

  1. switchport port-security mac-address sticky
  2. switchport port-security mac-address auto
  3. switchport port-security aging
  4. switchport port-security maximum 1 auto

Answer(s): A



What is the main purpose of the Cisco SD-Access underlay design?

  1. to enable automated network provisioning and configuration
  2. to provide network segmentation and isolation for security
  3. to support advanced firewall and IPS features
  4. to optimize network traffic routing and load-balancing

Answer(s): D

Explanation:

The main purpose of the Cisco SD-Access underlay design is to provide a scalable and optimized foundation for network traffic routing and load balancing. The underlay network is the physical infrastructure that supports the SD-Access fabric and allows efficient transport of data across different parts of the network. It helps with optimizing traffic flow, ensuring that data is routed effectively and with low latency, which is critical for supporting the overall network design.



When expanding an existing Cisco SD-Access network, in addition to the control plane, which two device roles are needed to create an additional fabric site? (Choose two.)

  1. leaf
  2. WLC
  3. edge
  4. border
  5. cEdge

Answer(s): A,D

Explanation:

Leaf devices are responsible for connecting end devices (such as computers, printers, etc.) to the fabric and handling traffic forwarding within the fabric.
Border devices connect the SD-Access fabric to external networks, such as the WAN or internet, and enable communication between the fabric and external resources.
The control plane is already handled by the Cisco SD-Access fabric, but these two roles are critical for extending the fabric to another site.



What is the purpose of the fabric management plane in a Cisco SD-Access architecture?

  1. create LISP-based ID for the end-to-end solution that is offered by SD-Access
  2. enable automation techniques for device deployments and configurations
  3. enable EID-to-RLOC mapping that is based on the BGP protocol
  4. create an underlay network that is based on the IS-IS routing protocol

Answer(s): B

Explanation:

The fabric management plane in a Cisco SD-Access architecture is responsible for managing the automation of device deployments and configurations within the fabric. It provides centralized control to simplify operations by automating tasks such as network device provisioning, configuration, and monitoring. This management plane enables a more streamlined and efficient deployment process across the SD-Access network, ensuring consistency and reducing manual configuration errors.
