  C. There is no requirement to support MPLS on the CE router and no modifications are required for a customer intranet.
  D. There is requirement to support MPLS on the CE router and no modifications are required for a customer intranet.
  C. There is no requirement to support MPLS on the CE router and no modifications are required for a customer intranet.

  A. Layer 2 access link QoS design
  B. enterprise-to-service-provider mapping models
  C. Layer 3 link access QoS design
  D. service provider service level agreements
  E. Layer 2 link access load balancing
  A. Layer 2 access link QoS design
  B. enterprise-to-service-provider mapping models
  D. service provider service level agreements

• Question 225:

  Which three components are required to support ISSU? (Choose three.)

  A. Supported line cards.
  B. SSO and NSF working.
  C. Redundant router for failover.
  D. Images that are preloaded into the file system.
  E. Traffic that is moved to another device.
  F. Active and standby RPs.
  B. SSO and NSF working.
  D. Images that are preloaded into the file system.
  F. Active and standby RPs.

• Question 226:

  A Tier 1 service provider is implementing a backbone network to support connectivity for multiple Tier 2 service providers, by using a Carrier Supporting Carrier design. Each Tier 2 service provider requires the ability to implement MPLS through the Tier 1 backbone. What occurs with respect to traffic for the Tier 2 providers?

  A. The Tier 2 provider uses MPLS over GRE tunnels for each customer VRF to create an LSP through the Tier 1 backbone.
  B. Connectivity between Tier 2 providers is established via a full mesh of MPLS L2VPN circuits.
  C. Tier 2 traffic across the backbone network has an additional label pushed onto the existing MPLS label stack.
  D. The Tier 1 provider implements each Tier 2 provider into the backbone via BGP into the default global routing table.
  C. Tier 2 traffic across the backbone network has an additional label pushed onto the existing MPLS label stack.

• Question 227:

  In a segment routing-enabled network, which two protocols perform label distribution? (Choose two)

  A. IS-IS
  B. LDP
  C. BGP
  D. OSPF
  E. RSVP-TE
  A. IS-IS
  D. OSPF

• Question 228:

  DRAG DROP

  Drag and drop the QoS functions from the left onto the correct QoS enabling features on the right.

  Select and Place:

  

  

• Question 229:

  What is the advantage of BGP confederation compared to BGP route reflector implementation?

  A. Confederation provides better redundancy. Route reflector clients can peer to only one cluster
  B. Confederation allows use of template session and template policy. Route reflector can use only peer-group
  C. The IBGP policies can differ internally within and between the sub-autonomous systems
  D. Confederation is more scalable. Route reflector implementation still requires confederation to eliminate completely the full mesh requirement
  C. The IBGP policies can differ internally within and between the sub-autonomous systems

• Question 230:

  Which two requirements to deploy 6PE and 6VPE solutions are mandatory? (Choose two.)

  A. MPLS is enabled on the core, distribution, and edge devices.
  B. A triple stack is enabled on PE devices.
  C. The network has at least six PE devices.
  D. A dual stack is enabled on all the P and PE devices in a network.
  A. MPLS is enabled on the core, distribution, and edge devices.
  D. A dual stack is enabled on all the P and PE devices in a network.
