Designing Cisco Enterprise Networks (ENSLD) Questions 171–175 (page: 36)

Updated On: 10-Feb-2026

An engineer is designing a networking solution to allow two hosts to communicate--one host located within the company A network and the other within the company B network. The two companies have no other plans for future additional connections. Both companies want to use a single secure and encrypted internet connection, and the configuration must be as simple as possible. Which network solution must the engineer choose?

  1. policy-based IPsec tunnel with static routing
  2. routed IPsec tunnel with OSPF routing
  3. MPLS VPN provided service with BGP routing
  4. single DMVPN with EIGRP routing

Answer(s): A



An architect is designing a connectivity solution for a customer's two small branch offices. The customer wants a cost-effective design, no routing overhead, and some down time during the year is acceptable. Which connectivity solution must the architect choose?

  1. single-homed
  2. dual multihomed
  3. single multihomed
  4. dual-homed

Answer(s): A



An architect is designing a network for an enterprise site. The design must use an active/backup design for the WAN. It must guarantee the SLA for several applications regardless of which connection is used. Which deployment model should the architect choose?

  1. hybrid WAN using MPLS VPN and internet VPN from two separate ISPs
  2. MPLS WAN from two separate ISPs
  3. internet WAN from two separate ISPs
  4. hybrid WAN using MPLS VPN and internet VPN from a single ISP

Answer(s): B



An enterprise needs to enhance its WAN availability after a recent outage with its only MPLS provider. The proposed solution must have a quick deployment, be affordable, be reliable, and work as a backup for the enterprise's primary MPLS connection. Which solution meets these requirements?

  1. Deploy an additional WAN router and use a floating static route.
  2. Contract an internet connection and deploy DMVPN.
  3. Deploy BFD echo mode and probe provider PE.
  4. Contract another MPLS provider and deploy GET VPN.

Answer(s): B

Explanation:

To enhance WAN availability quickly and affordably, while ensuring reliability and acting as a backup for the MPLS connection, contracting an internet connection and deploying DMVPN (Dynamic Multipoint Virtual Private Network) is an ideal solution. DMVPN allows for the creation of secure, scalable, and flexible VPNs over the internet, which can serve as a backup for the primary MPLS link. It offers quick deployment and does not require the enterprise to invest in additional expensive MPLS connections. DMVPN can also work seamlessly with existing infrastructure and is cost-effective compared to adding another MPLS provider.



DRAG DROP (Drag and Drop is not supported)

Drag and drop the Cisco Catalyst SD-WAN components from the left to their definitions on the right.

Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



vSmart controller: uses OMP to distribute routes and policy information to WAN Edge routers. vManage: GUI interface used to manage Cisco Catalyst SD-WAN devices. WAN Edge: forwards security, encryption, QoS, and routing protocols.
