問題 #315
An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:
- Each subnet must receive no less than 10 Mbps of download bandwidth
during peak traffic times.
- A subnet can use up to 40 Mbps during nonpeak traffic times if the
other subnets are idle.
- Download traffic must never experience a delay.
Which solution must the architect choose?
A. bandwidth percentage and rate-limiting
B. bandwidth percentage and policing
C. rate-limiting and shaping
D. shaping and policing
答案：B
解題說明：
Shaping: Shaping is used to control the traffic flow by buffering excess packets during periods of high demand and then releasing them at a rate that conforms to the desired profile. In this case, shaping can be employed to ensure that each subnet receives no less than 10 Mbps during peak traffic times.
Policing: Policing is used to enforce traffic policies by discarding or remarking packets that exceed specified rate limits. In this scenario, policing can be employed to ensure that a subnet does not exceed its allocated bandwidth (40 Mbps) during non-peak times.

問題 #317
When is it advisable to provide dedicated control plane nodes within a Cisco SD-Access design?
A. in a design where fabric edge nodes are unable to provide control plane functionality
B. in a small deployment where border nodes are not required
C. in designs without Cisco DNA Center
D. when there is a requirement for frequent roaming of endpoints across fabric edge nodes
答案：D
問題 #318
Refer to the exhibit. A customer needs to apply QoS to the network management traffic passing through the GigabitEthernet0/2 interface. All eight queuing classes are in use, so the new requirement must be integrated into the existing policy. Which solution must the customer choose?
A. Mark the traffic to DSCP CS2 and assign it to the ROUTING class Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the ROUTING class
B. Mark the traffic to DSCP CS6 and assign it to the ROUTING class Then, prioritize traffic within the class.
C. Mark the traffic to DSCP CS4 and assign it to the SIGNALLING class. Then, prioritize traffic within the class.
D. Mark traffic to DSCP CS5 and assign it to the SIGNALLING class. Then, baseline existing queue sizes to determine if additional bandwidth can be provisioned to the SIGNALLING class.
