Designing Cisco Enterprise Networks (ENSLD) Questions and Answers

Question 29

An engineer is designing a network for a customer running a wireless network with a common VLAN for all APs. The customer is experiencing unicast flooding in the Layer 2 network between the aggregation and access layers. The customer wants to reduce the flooding and improve convergence time. Which solution meets these requirements?

Options:

Migrate all APs to a common Layer 2 access layer switch and run Layer 3 from the aggregation layer to all remaining access layer switches.

Align HSRP primary and STP root bridges and reduce ARP timers to match CAM timers on the aggregation layer switches.

Migrate to a Layer 3 access campus design if the APs can run on separate VLANs.

Align HSRP primary and STP root bridges if the APs cannot run on separate VLANs.

Question 30

An enterprise customer has these requirements:

end-to-end QoS for the business-critical applications and VoIP services based on CoS marking.

flexibility to offer services such as IPv6 and multicast without any reliance on the service provider.

support for full-mesh connectivity at Layer 2.

Which WAN connectivity option meets these requirements?

Options:

VPWS

MPLS VPN

DMVPN

VPLS

Question 31

Refer to the exhibit. A network engineer working for a private service provider with an employee ID: 4670:71:451 must design a BGP solution based on:

All traffic originating from AS100 must pass through AS200 to reach the NTP and DHCP server

When a link failure occurs between R3 and R4, traffic must follow the R2-R9 link to reach the NTP and DHCP server.

Which solution must the design include?

Options:

Routers R3 and R10 advertise an IGP metric into BGP during redistribution in both directions.

Router R6 influences the paths of R9 and R11 to the DC with a higher AS-PATH value.

Routers R3 and R10 advertise a lower local preference for outgoing traffic and a higher AS-PATH value for incoming traffic.

Router R3 applies a local preference of 200 for R1. R2. R9. and R11 routers to reach the data center.

Question 32

How do endpoints inside an SD-Access network reach resources outside the fabric?

Options:

a VRF fusion router is used to map resources in one VN to another VN

Fabric borders use VRFs to map VNs to VRFs

SD-Access transit links are used to transport encapsulated traffic from one fabric to another

A fabric edge is used to de-encapsulate VXLAN traffic to normal IP traffic then transported over the outside network
