A. QPPB policies affect only egress traffic.
B. QoS policies rely exclusively on BGP attributes to manipulate traffic.
C. QoS policies are identified in the MPLS forwarding table.
D. QoS policies use BGP to gain full coverage on the network.
Question 173

A. The network does not support BIDIR-PIM.
B. The network is partially upgraded to support BIDIR-PIM.
C. The router has not been configured to advertise itself.
D. No interface for carrying traffic for multicast groups has been configured.
Question 174
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 af0 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 175
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.
Question 176
A network operator needs to implement PIM-SSM multicast configuration on a customer's network so that users in different domains are able to access and stream live traffic.
Which two actions must the engineer perform on the network to make the streaming work? (Choose two.)
A. Enable IGMP version 3 at the interface level.
B. Enable PIM dense mode on the device.
C. Enable PIM sparse mode on the device.
D. Enable IGMP version 2 at the interface level.
E. Configure at least one MSDP peer on the network.
Question 177
Which protocol is used for communication between the PCE and PCC?
A. POP
B. CEF
C. PCEP
D. ICMP
Question 178
A network engineer is configuring RIP as the routing protocol between multiple PEs and CEs. The engineer must avoid advertising the same routes back to their sources.
Which action should be performed on the routers to accomplish this task?
A. Define the site of origin on each interface.
B. Configure a different route distinguisher for each prefix.
C. Define VRFs on each device to separate the traffic.
D. Enable bidirectional forwarding detection on each device.
Question 179
A network engineer is deploying VPLS configuration between multiple PE routers so that customer's remote offices have end-to-end LAN connectivity.
Which additional configuration should the engineer perform on the PE routers to enable the virtual switch instance?
A. l2 vfi ciscotest manual vpn id 100 neighbor 192.168.2.2 encapsulation mpls neighbor 192.168.3.3 encapsulation mpls
B. interface GigEthernet 1/1 switchport mode trunk switchport trunk encap dot1q switchport trunk allow vlan 2-10
C. interface Vlan 5 xconnect vfi ciscotest
D. interface Vlan 100 xconnect vfi ciscotest ip address 192.168.1.1 255.255.255
Question 180
The network-engineering team of a service provider is integrating several recently acquired networks into a more scalable common Unified MPLS architecture.
The new network architecture will support end-to-end VPNv4 and VPNv6 services with these requirements:
- The IGP of the core layer is IS-IS in Area 0.
- The IGP of the aggregation layers is OSPF in Area 0.
- The LDP protocol is used to distribute label bindings within each IGP domain.
Which task must the network engineer perform when implementing this new architecture?
A. Configure a BGP session between the ABR routers of each IGP domain to exchange VPNv4 or VPNv6 prefixes.
B. Configure mutual redistribution of each IGP domain's loopback prefix to provide end-to-end LDP LSP.
C. Configure the ABR in each IGP domain to preserve next-hop information on all VPNv4 and VPNv6 prefixes advertised by the PE.
D. Configure BGP-LU between ABR routers of each IGP domain to carry MPLS label information in NLRI.
