In Cisco SD-Access, virtual networks create segmentation that allows for separation of users and resources. How is this type of segmentation described?

• A.  micro
• B.  stretched
• C.  macro
• D.  inter-VN

A customer has several remote sites connected with their headquarters through microwave links.
An engineer must propose a backup WAN solution based on these conditions:

Which backup WAN link type the engineer recommend?

• A.  802.15.1 Bluetooth
• B.  LTE
• C.  Laser link
• D.  802.16 WiMAX

An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution engineer choose?

• A.  Policing
• B.  Traffic shaping
• C.  Queuing
• D.  Policer with markdown

What is the main purpose of the Cisco SD-Access control and data plane?

• A.  to optimize network performance by controlling data flow and routing decisions
• B.  to ensure that devices within the network can communicate effectively with one another
• C.  to ensure high availability by supporting redundancy and failover mechanisms
• D.  to support network growth by accommodating additional devices and endpoints

An engineer must design a solution to connect a customer to the Internet. The solution will include a Layer 3 circuit with a CIR of 50 Mbps from the service provider. The hand-off from the provider's switch to the customer's router is 1Gbps. Which solution should the engineer include to prevent potential issues with choppy voice traffic?

• A.  Implement hierarchical QoS with a parent policing policy.
• B.  Implement hierarchical QoS with a parent shaping policy
• C.  Add a bandwidth statement to the router interface.
• D.  Reduce the bandwidth of the connection to the router.
