Cisco 300-415 Online Questions & Answers

• Question 71:

  Which two metrics must a cloud Edge router use to pick the optimal path for a SaaS application reachable via a gateway site? (Choose two.)

  A. HTTP loss and latency metrics to the SaaS application
  B. BFD loss and latency metrics to the gateway site
  C. ICMP loss and latency metrics to the SaaS application
  D. HTTP loss and latency metrics to the gateway site
  E. BFD loss and latency metrics to the SaaS application
  A. HTTP loss and latency metrics to the SaaS application
  B. BFD loss and latency metrics to the gateway site

  ---

  By design the cloud-edge router looks at the loss and latency on the paths of the gateway sites and calculates vQoe scores for each SaaS application and path based on that information. The VEdge router picks the optimal path via these methods. https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/SDWAN/CVD-SD-WAN-Cloud-onRamp-for-SaaS-Deployment-Guide-2018JUL.pdf

• Question 72:

  Which component of the Cisco SD-WAN secure extensible network provides a single pane of glass approach to network monitoring and configuration?

  A. APIC-EM
  B. vSmart
  C. vManage
  D. vBond
  C. vManage

  ---

  vManage - The vManage controller is the centralized network management system that provides the GUI interface. This single pane of glass allows easy deployment, configuration, monitoring, and troubleshooting of the Cisco SD-WAN network.

• Question 73:

  A vEdge platform is sending VRRP advertisement messages every 10 seconds. Which value configures the router back to the default timer?

  A. 2 seconds
  B. 5 seconds
  C. 1 second
  D. 3 seconds
  C. 1 second

• Question 74:

  Refer to the exhibit.

  

  The network administrator has configured a centralized topology policy that results in the displayed routing table at a branch office. Which two configurations are verified by the output? [Choose two.)

  A. The routing table is for the transport VPN.
  B. The default route is learned via OMP.
  C. This routing table is from a cEdge router.
  D. The default route is configured locally.
  E. The configured policy is adding a route tag of 300 to learned routes.
  B. The default route is learned via OMP.
  C. This routing table is from a cEdge router.

• Question 75:

  Which REST API call checks the status of an action that is performed on a device?

  A. admin status
  B. troubleshoot status
  C. configuration status
  D. monitor status
  D. monitor status

  ---

  The REST API call that checks the status of an action performed on a device in a Cisco SD-WAN environment is typically referred to as a "monitor status" API call. This call is used to check the status of various operations or actions that have been initiated on the device and monitor their progress or completion.

• Question 76:

  Which encryption algorithm secures binding exchanges Between Cisco TrustSec SXP peers?

  A. SEAL
  B. 3DES
  C. AES
  D. MD5
  C. AES

  ---

  Cisco TrustSec (CTS) is a technology that enables secure access and dynamic role-based access control in the network. The Security Group Tag (SGT) Exchange Protocol (SXP) is used to propagate SGTs across network devices. To ensure the secure exchange of these tags, Cisco uses encryption algorithms.

  AES (Advanced Encryption Standard): AES is widely used in many security protocols and standards because of its strong encryption capabilities. In the context of Cisco TrustSec, AES is the encryption algorithm used to secure binding exchanges between SXP peers. It provides robust encryption, ensuring the integrity and confidentiality of the data being exchanged. Implementation: When configuring SXP peers, the AES encryption ensures that the SGT information transmitted is secure and cannot be

  intercepted or tampered with by unauthorized entities.

• Question 77:

  What are the two advantages of configuration groups in a Cisco SD-WAN deployment? (Choose two.)

  A. An individual device has multiple tag rules.
  B. Individual devices are grouped based on a shared configuration.
  C. Individual devices are added to multiple groups.
  D. A subset of devices is identified with tags.
  E. Individual devices are associated with a configuration group and a device template.
  B. Individual devices are grouped based on a shared configuration.
  D. A subset of devices is identified with tags.

• Question 78:

  What is the function of colocation in Cloud OnRamp SaaS?

  A. In Cloud OnRamp, colocation supports the capability of virtualizing access-only locations and using colocation centers that require the customer to extend to the cloud.
  B. Cloud OnRamp incorporates regional colocation facilities by choosing between cloud access points at the remote site and regional cloud access points at the colocation facilities.
  C. With colocation facility in Cloud OnRamp, the customer faces challenges to virtualize the security and optimization infrastructure that influence traffic through network elements.
  D. The Cloud OnRamp for colocation solution restricts the creation of different VNF service chains orchestrated in Cisco vManage and deployed on a cluster in a colocation facility.
  B. Cloud OnRamp incorporates regional colocation facilities by choosing between cloud access points at the remote site and regional cloud access points at the colocation facilities.

• Question 79:

  Refer to the exhibit. The engineering must assign community tags to 3 of its 74 critical server networks as soon as possible as they are advertised to BGP peers. These server networks must not be advertised outside AS.

  

  Which configuration fulfills this requirement?

  

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

• Question 80:

  An organization wants to use the cisco SD-WAN regionalized service-chaining feature to optimize cost and user experience with application in the network, which allows branch routers to analyze and steer traffic toward the required network function. Which feature meets this requirement?

  A. Cloud Services Platform
  B. VNF Service Chaning
  C. Cloud onRamp for Colocation
  D. Cloud onRamp for laaS
  C. Cloud onRamp for Colocation

  ---

  With the Cisco SD-WAN Cloud onRamp for Colocation solution built specifically for colocation facilities, the solution routes the traffic to the best-permissible path from branches and remote workers to where all applications are hosted" https://www.cisco.com/c/dam/en/us/solutions/collateral/enterprise-networks/sd-wan/nb-06-cisco-sd-wan-ebook-cte-en.pdf
