Three of the 502 questions in this pack

Question 1

Which component of the Cisco SD-WAN architecture oversees the control plane of overlay network to establish, adjust, and maintain the connections between the WAN Edge devices that form the Cisco SD-WAN fabric?

  1. APIC-EM
  2. vSmart
  3. vManage
  4. vBond
Show answer and explanation

Correct answer: B. vSmart

The vSmart controller is responsible for overseeing the control plane of the SD-WAN overlay network. It establishes, adjusts, and maintains connections between WAN Edge devices by distributing policies and ensuring proper fabric formation. APIC-EM is a legacy management platform, vManage handles management and monitoring functions, and vBond facilitates initial authentication and NAT traversal rather than controlling the overlay connections.

Why the other options are wrong

  • A. APIC-EM is a legacy Cisco management platform, not part of the modern SD-WAN control plane architecture.
  • C. vManage is the management plane component responsible for configuration, monitoring, and analytics, not control plane overlay management.
  • D. vBond is an orchestration component that facilitates NAT traversal and initial device onboarding, not the primary control plane controller.

Question 2

Which two hardware platforms support Cisco IOS XE SD-WAN images? (Choose two.)

  1. ISR4000 series
  2. ISR9300 series
  3. vEdge-1000 series
  4. ASR9000 series
  5. ASR1000 series
Show answer and explanation

Correct answer: A, E

A. ISR4000 series E. ASR1000 series The ISR 4000 series and ASR 1000 series are Cisco IOS XE routers that can be loaded with the IOS XE SD-WAN image and onboarded as WAN Edge devices in the overlay. Both platforms appear in the Cisco SD-WAN device compatibility matrix alongside the Catalyst 8000 family and ISR 1000 series. Platforms running other operating systems, such as Viptela OS or IOS XR, cannot run an IOS XE SD-WAN image.

Why the other options are wrong

  • B. There is no ISR 9300 router series in the Cisco portfolio, so it cannot be a supported IOS XE SD-WAN platform.
  • C. vEdge-1000 appliances run Viptela OS, now called Cisco SD-WAN OS, and use the vEdge software image rather than IOS XE.
  • D. The ASR 9000 series is a service provider aggregation platform running IOS XR, which has no SD-WAN edge image.

Question 3

What is a default protocol for control plane connection?

  1. HTTPS
  2. TLS
  3. IPsec
  4. DTLS
Show answer and explanation

Correct answer: D. DTLS

DTLS (Datagram Transport Layer Security) is the default protocol used for control plane connections in Cisco SD-WAN. DTLS provides secure, encrypted communication over UDP and is preferred for WAN environments where packet loss and latency are concerns. While TLS is related, it operates over TCP; HTTPS is an application layer protocol; and IPsec is used for data plane encryption between WAN Edge devices, not for control plane signaling.

Why the other options are wrong

  • A. HTTPS operates over TCP at the application layer and is not the default control plane protocol.
  • B. TLS operates over TCP and is less suitable for WAN control plane traffic compared to DTLS over UDP.
  • C. IPsec is used for encrypting data plane traffic between WAN Edge devices, not for control plane communication.

What makes the ENSDWI hard

The 300-415 tests a control plane most engineers have never run in production. Plenty of candidates manage traditional WANs; far fewer have stood up controllers, built OMP policies or debugged a TLOC that will not come up, and the exam assumes you have.

Controller deployment and certificates, OMP routes and TLOC attributes, device and feature templates, centralised versus localised policy, application-aware routing and SLA classes, Direct Internet Access, security policy and QoS are the configuration a real SD-WAN engineer lives in every day. Candidates who know routing but have not internalised the SD-WAN policy model consistently underperform, since centralised policy logic behaves like nothing in traditional IOS. Roughly 55 to 65 questions in 90 minutes.

About the exam

The 300-415 ENSDWI certifies engineers who design, deploy and operate Cisco Catalyst SD-WAN: controller architecture, OMP, device templates, centralised and localised policies, application-aware routing, security and QoS. It counts as a concentration exam toward the CCNP Enterprise certification, paired with the 350-401 ENCOR core, and earns a Specialist certification on its own. Valid for three years.

Exam domains

  • Architecture: 20%
  • Controller deployment: 15%
  • Router deployment: 20%
  • Policies: 20%
  • Security and quality of service: 15%
  • Management and operations: 10%

55 to 65 questions, 90 minutes, variable passing score (Cisco does not publish it), US$300 per attempt, Pearson VUE testing centres or online proctored, valid for three years.
