Cisco 300-415 Online Questions & Answers

• Question 311:

  What happens if the intelligent proxy is unreachable in the Cisco SD-WAN network?

  A. The block-listed domains are unresolved.
  B. The Cisco Umbrella Connector locally resolves the DNS request.
  C. The grey-listed domains are unresolved.
  D. The Cisco Umbrella Connector temporarily redirects HTTPS traffic.
  C. The grey-listed domains are unresolved.

  ---

  Explanation

  One potential limitation in using intelligent proxy unicast IP addresses is the probability of the datacenter going down when the client is trying to send the traffic to the intelligent proxy unicast IP address. This is a scenario where a client has completed DNS resolution for a domain which falls under grey-listed domain and client's HTTP/(S) traffic is being sent to one of the obtained intelligent proxy unicast IP address. If that datacenter is down, then the client has no way of knowing it.

  The Umbrella Connector does not act on the HTTP and HTTPS traffic. The connector does not redirect any web traffic or alter any HTTP/(S) packets.

• Question 312:

  Explanation

  1. Route Resolvability

  Next-hop TLOC is Reachable (data plane BFD session is here)

  2. Prefer highest route preference

  3. Prefer highest TLOC preference

  4. Prefer best origin code (Connected, Static, eBGP, EIGRP Internal, OSPF Intra, OSPF Inter, OSPF External, EIGRP External iBGP, Unknown/Unset 5. Prefer OMP Route with lowest origin metric

  6. Route Source Preference On vSmart: prefer Edge router-sourced route over vSmart-sourced route

  7. Prefer route received from lowest System-IP 8. Prefer route from highest Private TLOC IP-address originated from the same site-id

  9. outbound control policy

  10. send-path-limit

• Question 315:

  Refer to the exhibit.

  

  CSRv1 must redistribute OMP routes into OSPF Area 1 that must be seen as type 7 LSA by RTR1.

  CSRv1 must also advertise the default route toward RTR1, which is learned via OMP.

  Which two configurations must the engineer implement to meet these requirements? (Choose two.)

  A. area 1 stub no-summary
  B. default-information originate always
  C. area 1 nssa default-information-originate
  D. redistribute omp subnet
  E. area 1 nssa no-summary
  C. area 1 nssa default-information-originate
  D. redistribute omp subnet

• Question 316:

  Which Cisco Umbrella SIG feature prevents users from browsing specific websites in a Cisco SD-WAN branch?

  A. DNS filtering
  B. Talos correlated intelligence
  C. cloud-delivered firewall
  D. web gateway
  A. DNS filtering

• Question 317:

  Which configuration component is used in a firewall security policy?

  A. intrusion prevention policy
  B. numbered sequences of match-action pairs
  C. application match parameters
  D. URL filtering policy
  B. numbered sequences of match-action pairs

• Question 318:

  What are the two impacts of losing vManage connectivity to fabric in the Cisco SD-WAN network? (Choose two.)

  A. Policy changes propagation stops.
  B. Creation of templates is impossible.
  C. BFD peering between WAN Edge devices are established.
  D. Statistics collection stops.
  E. IPsec tunnels tear down for WAN Edge devices.
  A. Policy changes propagation stops.
  D. Statistics collection stops.

  ---

  Explanation

  When vManage loses connectivity to the fabric, it can no longer push policy changes to the WAN Edge devices (A) or collect statistics and monitoring data (D). This can impact the network's ability to adapt to changes and monitor its performance effectively.

• Question 319:

  Refer to the exhibit.

  

  The SD-WAN network is configured with a default full-mesh topology. The network engineer wants the Rome WAN Edge to use the MPLS TLOC as the preferred TLOC when handling Telnet traffic, as long as the MPLS link has the following characteristics:

  Loss: 5%

  Latency: 100 ms

  Jitter: 100 ms

  Which configuration must the network engineer use to create a list that classifies the MPLS link characteristics?

  

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

  ---

  Explanation

  Configuration Analysis: The configurations provided in the images must be evaluated to determine which option correctly classifies the MPLS link based on the given criteria of loss, latency, and jitter.

  Preferred TLOC Configuration: The network engineer needs to configure the SD-WAN policy to prefer the MPLS transport for Telnet traffic, ensuring the link characteristics match the specified thresholds.

• Question 320:

  Refer to the exhibit.

  

  An engineer is modifying an existing data policy for DIA in VPN 23. Web browsing traffic toward government websites must be admitted for DIA. All other traffic must follow the regular routing path.

  Which policy sequence meets these requirements when appended to the existing configuration?

  

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