ENCOR SD-WAN Question Bank (4 Questions)

Browse all 4 practice questions covering Cisco SD-WAN for the ENCOR certification exam. Each question includes the full answer and a detailed explanation to help you understand the concepts.

  1. Question 1Architecture

    Which SD-WAN component is responsible for establishing the data plane tunnels?

    AvManage
    BvSmart
    CvBond
    DvEdge/cEdge✓
    Show Answer & Explanation
    Correct Answer: D
    Explanation:

    vEdge/cEdge routers establish IPsec data plane tunnels. vManage is NMS, vSmart is the centralized controller, and vBond is the orchestrator for initial authentication.

  2. Question 2Virtualization

    In Cisco SD-WAN, which component distributes routing policy to vEdge routers?

    AvManage
    BvSmart controller✓
    CvBond orchestrator
    DOMP (Overlay Management Protocol)
    Show Answer & Explanation
    Correct Answer: B
    Explanation:

    vSmart controller distributes routing information, policies, and encryption keys to vEdge routers using OMP (Overlay Management Protocol).

  3. Question 3Architecture

    Which Cisco SD-WAN component is responsible for establishing the control plane, distributing policies, and managing certificates?

    AvEdge / WAN Edge router
    BvSmart Controller✓
    CvManage
    DvBond Orchestrator
    Show Answer & Explanation
    Correct Answer: B
    Explanation:

    The vSmart Controller establishes the control plane using OMP (Overlay Management Protocol), distributes routing information and policies to WAN edge routers, and manages encryption keys. vManage is the management plane (GUI/API). vBond is the orchestration plane (authentication, NAT traversal). WAN Edge routers form the data plane.

  4. Question 4Architecture

    What are the benefits of SD-WAN over traditional WAN with MPLS?

    ASD-WAN is always faster
    BCentralized management, application-aware routing, support for multiple transports (MPLS+internet+LTE), lower cost, and encrypted overlay✓
    CSD-WAN replaces all routing
    DMPLS is always better
    Show Answer & Explanation
    Correct Answer: B
    Explanation:

    SD-WAN benefits: centralized orchestration (vManage), application-aware routing (steer apps per SLA), transport independence (MPLS, broadband, LTE, 5G), encrypted overlay (IPsec), zero-touch provisioning, and cost savings (augment MPLS with cheaper internet). SD-WAN doesn't replace MPLS but offers flexibility.

ENCOR SD-WAN Exam Tips

Cisco SD-WAN questions in ENCOR are typically scenario-based. Focus on service-level decision making aligned to official exam objectives. Priority concepts: sd-wan, viptela, vmanage, vsmart, vbond, vedge.

What ENCOR Expects

  • Anchor your answer in select the most practical, secure, and scalable answer for the stated scenario.
  • SD-WAN scenarios for ENCOR are frequently mapped to Domain 1 (15%), Domain 2 (10%), so read the objective carefully before picking controls or architecture.
  • Expect multi-service scenarios where SD-WAN interacts with IAM, networking, storage, or observability patterns rather than appearing as an isolated service question.
  • When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Professional) and managed-service best practices.

High-Value SD-WAN Concepts

  • Know the core SD-WAN building blocks cold: sd-wan, viptela, vmanage, vsmart.
  • Review the edge-case features and limits for vbond, vedge; these details are commonly used to differentiate answer choices.
  • Practice service-integration reasoning: how SD-WAN pairs with Architecture, Virtualization, Infrastructure in real deployment patterns.
  • For ENCOR, explain why the chosen SD-WAN design meets reliability, security, and cost expectations better than the alternatives.

Common ENCOR Traps

  • Watch for answers that partially solve the requirement but miss operational constraints.
  • Questions in Architecture often include distractors that look correct for SD-WAN but violate least-privilege, durability, or availability requirements.
  • Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
  • If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.

Fast Review Checklist

  • Can you compare at least two SD-WAN implementation paths and justify which one best fits the scenario?
  • Can you map the chosen answer back to Architecture (15%) outcomes for ENCOR?
  • Can you explain security and access boundaries for SD-WAN without relying on default-open assumptions?
  • Can you describe how SD-WAN integrates with Architecture and Virtualization during failure, scaling, and monitoring events?
