Q2. 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.

Which of the following would need to be reviewed to ensure stability in their network? 

A. Assigning unique Route Target ID's 

B. Assigning unique Route Distinguishers 

C. Assigning unique IP address space for the Enterprise NAT/Firewalls 

D. Assigning unique VRF ID's to each Layer 3 VPN

Q7. Refer to the exhibit. 

Company A is running a single-area OSPF, and Company B is running RIP as the IGP with no overlapping IP address spaces. Company A has just acquired Company B and both networks must be merged. Which three design components are recommended to guarantee connectivity and redundancy between the two networks? (Choose three.) 

A. Enable mutual redistribution between OSPF and RIP on one border router. 

B. Enable mutual redistribution between OSPF and RIP on Router A and Router B using route tags. 

C. Increase the administrative distance to 130 for the OSPF external prefixes on Router A and Router B. 

D. Implement an ACL on Router A and Router B to prevent OSPF external routes from being installed in the OSPF database. 

E. Filter external routes on Router A and Router B based on route tags.
