Cisco CCNP Enterprise 300-415 Questions & Answers

• Question 211:

  How is TLOC defined?

  A. It is represented by a unique identifier to specify a site in a SD-WAN architecture.

  B. It specifies a Cisco SD-WAN overlay in a multitenant vSMART deployment.

  C. It is represented by a group of QoS policies applied to a WAN Edge router.

  D. It is a unique collection of GRE or IPsec encapsulations, link color, and system IP address.

  Correct Answer: D

  Each TLOC is uniquely identified by a 3-tuple comprising the system IP address, a color, and an encapsulation.

• Question 212:

  Which vBond system configuration under VPN 0 allows for a routable public IP address even if the DNS name, hostname, or IP address of the vBond orchestrator are omitted?

  A. WAN

  B. local

  C. dns-name

  D. vbond-only

  Correct Answer: B

• Question 213:

  Refer to the exhibit.

  

  The network team must configure branch B WAN Edge device 103 to establish dynamic full-mesh IPsec tunnels between all colors with branches over MPLS and Internet circuits. The branch ts configured with:

  

  Which configuration meets the requirement?

  

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 214:

• Question 215:

  Which plane builds and maintains the network topology and makes decisions on traffic flows?

  A. data

  B. orchestration

  C. management

  D. control

  Correct Answer: D

  In Cisco SD-WAN, the plane responsible for building and maintaining the network topology and making decisions on traffic flows is the Control Plane. The Control Plane in Cisco SD-WAN is managed by the vSmart controllers, which are responsible for orchestrating network policies, maintaining the network topology, and making intelligent routing decisions.

• Question 216:

  What is the procedure to upgrade all Cisco SD-WAN devices to a recent version?

  A. The upgrade is performed for a group of WAN Edge devices first to ensure data-plane availability when other controllers are being updated.

  B. Upgrade and reboot are performed first on vManage, then on vBond, then on vSmart, and finally on the Cisco WAN Edge devices.

  C. The upgrade is performed first on vManage, then on WAN Edge devices, then on vBond, and finally on vSmart. The reboot must start from WAN Edge devices.

  D. Upgrade and reboot are performed first on vBond, then on vSmart, and finally on the Cisco WAN Edge devices.

  Correct Answer: B

• Question 217:

  Which secure tunnel type should be used to connect one WAN Edge router to other WAN Edge routers?

  A. DTLS

  B. SSL VPN

  C. IPsec

  D. TLS

  Correct Answer: C

  After being onboarded to the SD-WAN overlay by the controllers, the WAN Edge router joins the fabric by establishing IPsec (default) or GRE tunnels to other WAN Edge router

• Question 218:

  A customer has MPLS and Internet as the TLOC colors. An engineer must configure controllers with the Internet and not with MPLS. Which configuration achieve this requirement on vManage?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 219:

  What is a benefit of using REST APIs?

  A. predefined automation and orchestration platform for event management and logging

  B. user-defined automation and integration into other orchestration systems or tools

  C. vAnalytics to simplify operational services integration and real-time event monitoring

  D. predefined SD-WAN controller with other platform integration for event management and logging

  Correct Answer: B

  One of the key benefits of using REST APIs (Representational State Transfer Application Programming Interfaces) is their flexibility and the ability for users to define their own automation and integrate systems or tools according to their specific needs. REST APIs allow for the creation of custom scripts and applications that can interact with different services and platforms, making it a powerful tool for automation and integration in various contexts, including software development and system administration.

• Question 220:

  In a customer retail network with multiple data centers, what does the network administrator use to create a regional hub topology?

  A. app route policy on vSmart

  B. data policy on vSmart

  C. control policy on vSmart

  D. control policy on vManage

  Correct Answer: C

  Control policies are used to define the control plane behavior of the SD-WAN network, including how routing decisions are made. When creating a regional hub topology, control policies are used to specify how traffic is routed within the network, how hubs are connected, and how regional or data center hubs are defined. These policies help establish the network's architecture and routing behavior.
