• Question 33:

  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

  Correct Answer: B

  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 Legacy systems are outdated and vulnerable to hackers who know how much time it takes for each server location or firm's IT department to have access control capabilities.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 35:

  What does forward error correction addresses in Cisco SD-WAN?

  A. reduced application performance degradation related to service degradation

  B. applications with occasional invalid data input and poor performance

  C. traffic flows with increased delay over a particular transport

  D. inefficient traffic forwarding caused by inbound shapers

  Correct Answer: B

• Question 36:

  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.

  Correct Answer: C

• Question 37:

  What is the function of the AppNav Controller in the Cisco SD-WAN AppNav solution?

  A. It provides information about configured optimization policies on SD-WAN edge devices.

  B. It accelerates specific traffic based on preconfigured policies.

  C. It intercepts and distributes network traffic based on configured policies.

  D. It provides configuration and monitoring for WAAS nodes.

  Correct Answer: C

• Question 38:

  Which application list is preconfigured?

  A. Cisco_Apps

  B. P2P_Apps

  C. Microsoft_Office365

  D. Google_Apps

  Correct Answer: D

• Question 39:

  Which routing protocol has the highest default administrative distance?

  A. IS-IS

  B. OMP

  C. IBGP

  D. external EIGRP

  Correct Answer: B

  Administrative Distance

  Administrative distance is the metric used to select the best path when there are two or more different routes to the same destination from multiple routing protocols. When the Cisco Catalyst SD-WAN Controller or the router is selecting the OMP route to a destination, it prefers the one with the lowest administrative distance value.
