Demo Questions
Question 1
Which three conditions can occur when metering traffic using a dual token bucket traffic policing QoS mechanism on Cisco routers? (Choose three.)
- A: conform
- B: pass
- C: violate
- D: exceed
- E: burst
- F: matched
Question 2
What is the correct formula for determining the CIR?
- A: CIR = Bc/Tc
- B: CIR = Bc x Tc
- C: CIR = Tc/Bc
- D: CIR = Bc + Be
- E: CIR = Tc/(Bc+Be)
- F: CIR = (Bc+Be)/Tc
Question 3
DS-TE implementations on Cisco routers support which bandwidth pool(s) and class type(s)? (Choose two.)
- A: global pool only
- B: subpool only
- C: global pool and subpool
- D: class-type 0 only
- E: class-type 1 only
- F: class-type 0 and class-type 1
Question 4
Which field in the MPLS shim header is used to support different QoS markings?
- A: IP precedence
- B: DSCP
- C: EXP
- D: ToS
- E: S
- F: Label
Question 5
On a Cisco IOS XR router, which mechanism protects the router resources by filtering and policing the packets flows that are destined to the router that is based on defined flow-type rates?
- A: LLQ
- B: LPTS
- C: Committed Access Rate
- D: Control Plane Policing
- E: Management Plane Protection
- F: NetFlow
- G: ACL
Question 6
When configuring LLQ (strict priority queue) on a traffic class using the Cisco IOS XR priority command on a Cisco ASR9K router, which additional QoS command is required for this traffic class?
- A: shape
- B: police
- C: random-detect
- D: bandwidth
Question 7
On the Cisco ASR9K router, when using the bandwidth command to specify the minimum guaranteed bandwidth to be allocated for a specific class of traffic, what will be used as the queuing algorithm?
- A: custom queuing
- B: CBWFQ
- C: WFQ
- D: FIFO
- E: priority queuing
Question 8
When implementing MPLS DS-TE on Cisco IOS XR routers, all aggregate Cisco MPLS TE traffic is mapped to which class type by default?
- A: class-type 0 (bandwidth global pool)
- B: class-type 1 (bandwidth subpool)
- C: class-type 2 (bandwidth priority)
- D: class type class-default (bandwidth best-effort)
Question 9
On the Cisco IOS XR, which MQC configuration is different than on the Cisco IOS and IOS XE?
- A: On the Cisco IOS XR, WRED can only be applied in the output direction.
- B: On the Cisco IOS XR, marking can only be applied in the input direction.
- C: On the Cisco IOS XR, LLQ can be applied in the input or output direction.
- D: On the Cisco IOS XR, LLQ can use up to four priority queues: level 1, level 2, level 3, and level 4.
Question 10
On Cisco routers, how is hierarchical QoS implemented?
- A: Within the parent policy, reference another child policy using the policy-map command.
- B: Within the child policy, reference another parent policy using the policy-map command.
- C: Use the policy-map command within a service-policy to implement nested policy-maps.
- D: Within the parent policy-map, reference another child policy-map using the service-policy command.
