  D. config t access-list 100 permit igmp host 0.0.0.0 host 239.10.10.10 access-list 100 permit igmp host 172.20.20.3 host 239.10.10.10 access-list 100 deny igmp any any interface GigabitEthernet1 ip igmp access-group 100 ip igmp version 2 end

  Correct Answer: C

• Question 305:

  A network engineer is implementing a QoS policy for outbound management traffic classification and marking on a CPE device with these requirements:

  Management protocols must be marked with DSCP AF class 2 with low drop probability.

  Monitoring protocols must be marked with DSCP AF class 1 with low drop probability.

  All remaining traffic must be marked with a DSCP value of 0.

  Which configuration must the engineer implement to satisfy the requirements?

  A. policy-map cpe-mgmt-policy class management set ip dscp af21 class monitoring set ip dscp af11 class class-default

  set ip dscp default

  end

  B. policy-map cpe-mgmt-policy class management set ip dscp af21 class monitoring set ip dscp af11

  class class-default

  set ip dscp af10

  end

  C. policy-map cpe-mgmt-policy class management set ip dscp af23 class monitoring set ip dscp af13 class class-default

  set ip dscp default

  end

  D. policy-map cpe-mgmt-policy class management set ip dscp af23 class monitoring set ip dscp af13 class class-default

  set ip dscp af0

  end

• Question 306:

  What occurs when a high bandwidth multicast stream is sent over an MVPN using Cisco hardware?

  A. The traffic uses the default MDT to transmit the data only if it is a (S, G) multicast route entry.

  B. A data MDT is created to if it is a (*, G) multicast route entries.

  C. A data and default MDT are created to flood the multicast stream out of all PIM-SM neighbors.

  D. A data MDT is created to allow for the best transmission through the core for (S, G) multicast route entries.

  Correct Answer: B
