  A. RESTCONF
  B. NETCONF
  C. EPP
  D. HTTPS
  B. NETCONF

  C. A domain is locally reachable.
  D. A domain is grey-listed.
  D. A domain is grey-listed.

• Question 416:

  Which action is performed during the onboarding process when a WAN Edge router is connected to ZTP server ztp.viptela.com?

  A. The router is connected to WAN Edge Cloud Center.
  B. The router receives its vBond Orchestrator information.
  C. The router is synced with vSmart Controller via an IPsec tunnel.
  D. The router is connected to vSmart Controller via a DTLS/TLS tunnel.
  B. The router receives its vBond Orchestrator information.

  ---

  Explanation

  A: There is no such thing as WAN Edge Cloud Center

  B: Correct

  C: WAN Edge Never connects with IPSEC Tunnel to vSmart.

  D: WAN Edge establishes OMP and control connections (TLS / DTLS) after successful authentication from vBond. Vbond is first in line.

  During the Zero Touch Provisioning (ZTP) process, when a WAN Edge router is connected to the ZTP server (in this case, ztp.viptela.com), one of the primary actions performed is the router receiving its vBond Orchestrator information. This information is crucial for the router to establish initial connectivity with the SD-WAN network and begin the onboarding process.

• Question 417:

  Which color type is assigned when a TLOC is configured behind NAT?

  A. MPLS
  B. private
  C. blue
  D. public
  D. public

  ---

  Explanation

  PUBLIC COLORS

  The public colors are 3g, biz-internet, blue, bronze, custom1, custom2, custom3, default, gold, green, lte, public-internet, red, and silver. They are intended to be used for public networks or in places where you will use public IP addressing of the transport IP endpoints, either natively or through NAT.

• Question 418:

  An enterprise has these three WAN connections:

  1. public Internet

  2. business Internet

  3. MPLS

  An engineer must configure two available links to route traffic via both links.

  Which configuration achieves this objective?

  A. omp no shutdown ecmp-limit 2
  B. omp no shutdown send-path-limit 2
  C. omp no shutdown overlay-as 2
  D. omp no shutdown route-limit 2
  A. omp no shutdown ecmp-limit 2

  ---

  Explanation

  The number of routes that get installed in the routing tables is subject to another OMP parameter called ecmp-limit.

• Question 419:

  Which behavior describes a WAN Edge router running dual DIA when its DPI engine has identified a cloud SaaS application?

  A. The gateway WAN Edge router DPI engine accepts the DNS query for SaaS applications, and DNS queries for noncloud applications follow the explicit path.
  B. The WAN Edge DPI engine never selects a subperforming DIA circuit for the first application, and the WAN Edge router finds the SaaS application.
  C. Existing flows change the path and drop the traffic when the performance of the chosen path degrades.
  D. Application traffic flows are routed over best performing DIA circuit, which makes the routing decision based on the best performing path.
  D. Application traffic flows are routed over best performing DIA circuit, which makes the routing decision based on the best performing path.

• Question 420:

  How does Cisco Umbrella respond to the client if the FQDN in the DNS query is one of the grey-listed domains?

  A. It returns the IP address of the content provider.
  B. It returns the unicast IP addresses of intelligent proxy.
  C. It returns the IP address of the blocked landing page.
  D. No response is sent: traffic is blocked.
  B. It returns the unicast IP addresses of intelligent proxy.
