A customer's environment includes hosts that support IPv6-only. Several of these hosts must communicate with a public web server that has only IPv4 domain name resolution. Which solution should the customer use in this environment?

• A.implement 6PE to resolve hostname resolution
• B.Implement NAT44 at the edge of the customer network
• C.utilize NAT64 to translate the addresses
• D.use 6to4 and a tunnel to translate the addresses

An architect is working on a design to connect a company's main site to several small to medium-sized remote branches. The solution must include redundant WAN links, but the customer has a limited budget and wants the ability to increase the link speed easily in the future. QoS will not on the branch routers so there is no need for consistent end-to-end QoS. Which solution does the architect propose?

• A.dual-homed WAN MPLS and Internet links via dual edge routers
• B.dual-homed Internet with dual edge routers running a hub-and-spoke VPN topology
• C.dual-homed WAN MPLS with single edge router
• D.dual-homed Internet with a single edge router running a site-to-site VPN topology

Exhibit:

• A.Make R11 an L2 router.
• B.Make R3 an L1L2 router.
• C.Make Area 0 L2-only.
• D.Make R31 an L1 router.

Refer to the exhibit.

An architect is designing a network for a customer supporting a Wake-on-LAN application. Which solution must the architect choose?

• A.spanning-tree uplinkfast on SW1
• B.spanning-tree uplinkfast on SW2
• C.IP directed-broadcasts on R2
• D.IP directed-broadcasts on R1

Refer to the exhibit. A company has some offices that are connected via dark fiber in New York. A network architect must optimize the network design based on the EIGRP routing protocol. The network has hierarchical addressing between 10 and 12 routers in each office. Routing convergence time must be at the minimum. What must the network architect do to reduce the query range?

• A.Use different EIGRP processes on edge routers.
• B.Configure stub areas on non-edge routers.
• C.Implement network summarization on edge routers.
• D.Configure route filtering on non-edge routers.
