A. recommended for high availability 

B. requires all sites to have dual Internet connections C. spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly

Q3. The Customer X network consists of an MPLS core, IS-IS running as IGP, a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which three options about the Overload Bit are true? (Choose three.) 

A. It is not recommended on BGP route reflectors. 

B. It only affects the use of the respective node as a transit node, and networks advertised within the LSPs of the node are still reachable. 

C. It can be set on a router during the startup process for a fixed period of time. 

D. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node. 

E. It can be set on a router until other interacting protocols have signaled convergence.

Q4. You work as a network designer for a company that is replacing their Frame Relay WAN with an MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in their distribution routers, and they would like to advertise their access routers through the MPLS network. Their service provider, however, only supports 1000 prefixes per VRF. Which two design solutions can be applied to ensure that your access routers will be able to reach all devices in your network? (Choose two.) 

A. Use prefix lists on your distribution routers to control which routes are sent to the MPLS network. 

B. On your distribution routers, configure null routes and aggregate routes for the prefixes in your network. 

C. Configure your distribution routers to send a default route to the MPLS network. 

D. Summarize the routes on the MPLS WAN interfaces of your distribution routers.

A. PVRSTP on all switches 

B. REP on all switches 

C. MST on all switches 

D. BPDU guard on Switch A and Switch D 

E. 8032 on ring A-B-C-D

Q6. You are the lead network designer for an enterprise company called ABC, and you are leading design discussions regarding IPv6 implementation into their existing network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these Layer 2 switches for successful IPv6 implementation. Which two responses should you give? (Choose two.) 

A. IPv6 is transparent on Layer 2 switches, so there is no need to make any changes to the Layer 2 switches. 

B. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches. 

C. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 snooping at Layer 2 switches. 

D. If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches. 

E. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND snooping at Layer 2 switches.
