• Question 372:

  How are policies deployed on cloud-hosted Cisco SD-WAN controllers?

  A. Policies are created on vManage and enforced by vManage.
  B. Policies are created on vSmart and enforced by vManage.
  C. Policies are created on vManage and enforced by vSmart.
  D. Policies are created on vSmart and enforced by vSmart.
  C. Policies are created on vManage and enforced by vSmart.

  Explanation

  vManage serves as the central management and orchestration platform for SD-WAN policies, where administrators can define and configure policies. vSmart controllers, on the other hand, enforce these policies by making routing and forwarding decisions based on the defined policies. vSmart controllers play a significant role in policy enforcement and control plane operations within the SD-WAN network.

• Question 373:

  An engineer must configure egress QoS for voice traffic.

  Which queue must the engineer configure on the WAN Edge router to accomplish the task?

  A. queue 0
  B. queue 1
  C. queue 3
  D. queues 7
  A. queue 0

  ---

  Explanation

  Queue 0 is reserved for Low Latency Traffic or (LLQ) in other words voice traffic.

  Queues 1-7 are available for data traffic.

• Question 374:

  Which protocol is used between redundant vSmart controllers to establish a permanent communication channel?

  A. IPsec
  B. HTTPs
  C. DTLS
  D. SSL
  C. DTLS

• Question 375:

  A network administrator is configuring an application-aware firewall between inside zones to an outside zone on a WAN edge router using vManage GUI.

  What kind of inspection is performed when the "inspect" action is used?

  A. Layer 7 inspection for TCP and Layer 4 inspection for UDP
  B. IPS inspection for TCP and-Layer 4 inspection for UDP
  C. stateful inspection for TCP and stateless inspection of UDP
  D. stateful inspection for TCP and UDP
  D. stateful inspection for TCP and UDP

  ---

  Explanation

  When the "inspect" action is used in the context of an application-aware firewall, it typically refers to stateful inspection for both TCP and UDP traffic. This allows the firewall to keep track of the state of network connections and make decisions based on the state of those connections.

• Question 376:

  What is a benefit of the application aware firewall feature in the Cisco SD-WAN solution?

  A. application monitoring
  B. application malware protection
  C. application visibility
  D. control policy enforcement
  C. application visibility

• Question 377:

  Which controller is excluded from the process of checking against the authorized, allowed list?

  A. vBond
  B. PnP
  C. vSmart
  D. vManage
  A. vBond

• Question 378:

  An engineer must configure VRRP for redundancy on WAN Edge router 1 running an earlier version than 20.6, considering WAN Edge router2 is configured correctly.

  Which configuration meets the requirement?

  

  

  

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 379:

  A network engineer configures QoS on a WAN Edge router to use a default bandwidth of 6K downstream and 8K upstream. The actual bandwidth in use must adjust dynamically according to the current available WAN bandwidth.

  Which configuration must the engineer apply?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

• Question 380:

  How does the replicator role function in cisco SD-WAN?

  A. WAN Edge devices advertise the rendezvous point to all the receivers through the underlay network.
  B. vSmart Controllers advertise the rendezvous point to all the receivers through the overlay network.
  C. WAN Edge devices advertise the rendezvous point to all receivers through the overlay network.
  D. vSmart Controllers advertise the rendezvous point to all the receivers through the underlay network.
  B. vSmart Controllers advertise the rendezvous point to all the receivers through the overlay network.

  ---

  Explanation

  For efficient use of WAN bandwidth, strategic Cisco SD-WAN routers can be deployed and configured as replicators throughout the overlay network. Replicators mitigate the requirement for a Cisco SD-WAN router with local sources or the PIM-RP to replicate a multicast stream once for each receiver. As discussed above, replicators advertise themselves, using OMP multicast-autodiscover routes, to the Cisco vSmart Controllers in the overlay network. The controllers then forward the replicator location information to the PIM-enabled Cisco IOS XE SD-WAN routers that are in the same VPN as the replicator.
