Demo Questions

Question 1
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 2
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 3
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 4
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 5
Refer to the Cisco IOS XR policy-map configuration exhibit. 

  

What is wrong with the policy-map configuration?

  • A: missing the priority percent command under class one and class two
  • B: missing the police command under class one and class two
  • C: missing the police command under class three
  • D: missing the priority bandwidth command under class one and class two
  • E: missing the bandwidth command under class one and class two



Question 6
When configuring class-based WRED on Cisco routers, which WRED parameter is not user configurable on a Cisco IOS XR but is user configurable on a Cisco IOS and IOS XE?

  • A: the ingress or egress direction where the class-based WRED policy will be applied
  • B: the maximum threshold
  • C: the minimum threshold
  • D: the mark probability denominator



Question 7
Which of the following three statements are correct regarding IPv6 QoS?  (Choose three.)

  • A: The traffic class field in the IPv6 header can be used to set specific precedence or DSCP values.
  • B: A 20-bit flow label field enables per-flow processing.
  • C: DS-TE is not supported by IPv6.
  • D: Per-hop behavior in IPv6 networks is based on EXP bits.
  • E: IPv6 QoS features are configured using the modular QoS CLI on Cisco routers.



Question 8
On the Cisco IOS XR, when using the match protocol command within a class-map to classify traffic, you noticed that the match protocol option on the Cisco IOS XR shows much fewer protocol options than on the Cisco IOS or IOS XE, like there is no option such as the match protocol yahoo-messenger command on the Cisco IOS XR. Why is this?

  • A: because the Cisco IOS XR router does not have the correct software packages installed
  • B: because when defining the class-map, the class-map type should be set to type inspect: class-map type inspect class-map-name command
  • C: because NBAR is not supported on the Cisco IOS XR
  • D: because flexible packet matching has not been enabled on the Cisco IOS XR router



Question 9
Which three steps are required to configure QPPB on Cisco IOS XR routers? (Choose three.)

  • A: Apply a QPPB route policy to the BGP process using the table-policy command
  • B: Apply a QPPB route policy to the BGP neighbor using the route-policy command
  • C: Define a QPPB route policy to match the customer routes, then set the IP precedence or qos-group
  • D: Define a QPPB route policy to match the customer IP precedence or qos-group markings, then set the BGP community
  • E: Enable QPPB on an interface using the ipv4 bgp policy propagation input ip-precedence|qos-group destination|source command
  • F: Enable QPPB on an interface using the ipv4 bgp policy propagation output ip-precedence|qos-group destination|source command



Question 10
The Cisco IOS and IOS XE qos pre-classify command allows which kind of packet classification on IP packets that are encapsulated with GRE and IPsec?

  • A: allows for packets to be classified based on the ToS byte values before packet encryption
  • B: allows for packets to be classified based on the ToS byte values after packet encryption
  • C: allows for packets to be classified based on the packet payload before packet encryption
  • D: allows for packets to be classified based on the packet payload after packet encryption
  • E: allows for packets to be classified based on the packet header parameters other than the ToS byte values after packet encryption
