Cisco 300-415 Online Questions & Answers

• Question 451:

  Which data policy configuration influences BGP routing traffic flow from LAN to WAN?

  

  

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

• Question 452:

  How is the scalability of the Manage increased in Cisco SD-WAN Fabric?

  A. Increase the bandwidth of the WAN link connected to the vManage
  B. Increase licensing on the vManage
  C. Deploy more than one vManage controllers on different physical server
  D. Deploy multiple vManage controllers in a cluster
  D. Deploy multiple vManage controllers in a cluster

  ---

  Explanation

  An SD-WAN overlay network can be managed by one Cisco SD-WAN Manager, or it can managed by a cluster, which consists of a minimum of three Cisco SD-WAN Manager instances. It is recommended that you build a network, especially a larger network, with a Cisco SD-WAN Manager cluster. The Cisco SD-WAN Manager manages all the Cisco vEdge devices in the overlay network, providing dashboard and detailed views of device operation, and controlling device configurations and certificates.

• Question 453:

  Which timer specifies information in the cache after all OMP sessions are lost at location S0123T4E56F78?

  A. advertisement interval
  B. EOR timer
  C. graceful restart timer
  D. hold time
  C. graceful restart timer

• Question 454:

  What is the advantage of installing the controller on-premises?

  A. automatic geographical redundancy and security
  B. full control of the data plane and the control plane
  C. scalability and a cost-saving
  D. ease of deployment and management
  B. full control of the data plane and the control plane

  Explanation

  Key benefices of on-premise systems 1. Greater security and privacy: On-premise systems are installed and operated on your premises, so your data is always kept secure and private, as long as you harden your platform and keep them up to date.

  2. More control and customization: On-premise systems give you more control over your security system. You can customize it to meet your specific needs and requirements, whereas Cloud-based systems are more limited in customization options.

  3. Higher performance: On-premise systems typically have higher performance than Cloud-based systems, as they don't rely on the Internet connection or power outages.

  4. Increased reliability: On-premise systems are less likely to experience downtime due to Internet connection issues, as they don't rely on the Cloud for their functionality.

  Disadvantages of on-premise systems 1. On-premise or legacy access control systems are becoming less secure every day. Legacy systems are outdated and vulnerable to hackers who know how much time it takes for each server location or firm's IT department to have access control capabilities. Hackers can exploit these vulnerabilities because they're already familiar with the decades-old technology used in these legacy security methods, making them an easy target.

  2. They can be expensive to purchase and maintain 3. It would be best to have a dedicated IT staff to manage them.

  4. They can be challenging to scale up or down to meet your organization's needs.

  5. They are less flexible than cloud-based systems.

• Question 455:

  Which Cisco router provides a distributed multicore architecture optimized for SD-WAN branch support?

  A. Cisco 1000 ISR series
  B. Cisco 2900 ISR series
  C. Cisco Catalyst 3850 series
  D. Cisco 3900 ISR series
  A. Cisco 1000 ISR series

• Question 456:

  Which Cisco SD-WAN component facilitates the initial communication between WAN Edge devices to join the fabric?

  A. WAN Edge Router
  B. vSmart Controller
  C. vManage
  D. vBond Orchestrator
  D. vBond Orchestrator

  ---

  Explanation

  Cisco vBond Orchestrator orchestrates the initial control connection between Cisco vSmart Controllers and edge routers.

• Question 457:

  A network administrator is configuring a WAN Edge router with two WAN connections and two TLOCs.

  Which two attributes of TLOCs must be configured? (Choose two.)

  A. group-id
  B. site-id
  C. encapsulation
  D. tloc-ip
  E. color
  C. encapsulation
  E. color

• Question 458:

  How is the software managed in Cisco SD-WAN?

  A. Software upgrade operation in the group must include vManage, vBond, and vSmart.
  B. Software downgrades are unsupported for vManage.
  C. Software images must be uploaded to vManage through HTTP or FTP.
  D. Software images must be transferred through VPN 512 or VPN 0 of vManage.
  B. Software downgrades are unsupported for vManage.

• Question 459:

  DRAG DROP

  Drag and drop the steps from the left into the sequence on the right for a WAN Edge router after powering on for zero touch provisioning.

  Select and Place:

  

  

• Question 460:

  Which protocol is used to propagate multicast join requests over the Cisco SD-WAN fabric?

  A. Auto-RP
  B. ARP
  C. OMP
  D. IGMP
  D. IGMP

  ---

  Explanation

  Cisco SD-WAN overlay multicast routing supports the Internet Group Management Protocol (IGMP) version 2 (defined in RFC 2236). Cisco vEdge devices use IGMP to process receiver membership reports for the hosts in a particular VPN and to determine, for a given group, whether multicast traffic should be forwarded and state should be maintained. vEdge routers listen for both IGMPv1 and IGMPv2 group membership reports.
