  Which configuration for WAN Edge routers will connect to the Internet?

  

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

  ---

  Explanation

  It's the only logical answer since the Interface IP and GW are in the same subnet

• Question 482:

  Refer to the exhibit.

  

  The engineering must assign tags to 3 Of its 74 server networks as soon as they are advertised to peers.

  These server network must not be advertised AS which configuration fulfil the requirement?

  

  

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

• Question 483:

  Which protocol detects path status (up/down), measures loss/latency/jitter, and measures the quality of the IPsec tunnel MTU?

  A. DTLS
  B. BFD
  C. OMP
  D. IP-SLA
  B. BFD

  ---

  Explanation

  Bidirectional Forwarding Detection (BFD) runs via the DTLS session between the remote site and the regional hub. BFD is a detection protocol that provides fast forwarding path failure detection times between two adjacent routers. It is used in SD-WAN to determine path liveliness (up/down) and quality (loss/latency/jitter and IPsec tunnel MTU).

• Question 484:

  Which policy configures an application-aware routing policy under Configuration > Policies?

  A. Data policy
  B. Centralized policy
  C. Localized policy
  D. Control policy
  B. Centralized policy

• Question 485:

  In Cisco SD-WAN, which protocol is used for control connections between Cisco SD-WAN devices?

  A. BGP
  B. DTLS
  C. OSPF
  D. OMP
  B. DTLS

• Question 486:

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

  A. ISR4000 series
  B. ISR9300 series
  C. vEdge-1000 series
  D. ASR9000 series
  E. ASR1000 series
  A. ISR4000 series
  E. ASR1000 series

• Question 487:

  What is the function of the OMP TLOCs in a Cisco SD-WAN network?

  A. represents services in the data center
  B. identifiers that map an OMP route to a physical site
  C. carries OMP service route information
  D. QoS tags that are used to prioritize traffic
  B. identifiers that map an OMP route to a physical site

• Question 488:

  Which process is continued by Cisco SD-WAN when packet duplication is enabled?

  A. Additional headers are added to outgoing packets to perform custom routing policies.
  B. Dynamic traffic is compressed and signaled before it is forwarded though the WAN.
  C. Copies of packets are sent over multiple WAN circuits to overcome packet loss.
  D. Application traffic is analyzed to find patterns and enable custom detection rules.
  C. Copies of packets are sent over multiple WAN circuits to overcome packet loss.

• Question 489:

  An engineer must improve video quality by limiting HTTP traffic to the Internet without any failover.

  Which configuration in vManage achieves this goal?

  

  

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

• Question 490:

  What do receivers request to join multicast streams in a Cisco SO-WAN network?

  A. IGMP membership reports directly with a multicast router
  B. Multicast service routes with the vSmart controller
  C. IGMP membership reports directly with the vBond orchestrator.
  D. PIM messages with the nearest neighboring multicast router.
  B. Multicast service routes with the vSmart controller

  ---

  Explanation

  In a Cisco SD-WAN network, multicast traffic management is handled differently compared to traditional IP multicast methods due to the nature of the overlay architecture.

  Multicast Service Routes: In Cisco SD-WAN, multicast receivers use the vSmart controller to request multicast streams. This is done via multicast service routes which the vSmart controller manages. The vSmart controller is responsible for maintaining and distributing multicast routing information to all edge devices in the network.
