A service provider is designing a new MPLS network for its customers. The design must support multiple customers with overlapping IP address spaces. Which Layer 3 technology should be used to ensure that customer traffic is isolated and that routing decisions are made correctly?

Use a single OSPF area for all customers and rely on route tags to distinguish them.

Use Network Address Translation (NAT) to translate all customer addresses to unique public addresses.

Use Virtual Routing and Forwarding (VRF) instances to create separate routing tables for each customer.

Use a single routing table for all customers and rely on access control lists to prevent overlap.

A regional bank is redesigning its core network. The design must support 50 branch offices, each with a /24 subnet, and a central data center. The routing team wants to minimize routing table size at the branches while ensuring fast failover if a WAN link goes down. Which Layer 3 design approach is most appropriate?

Use RIP with split-horizon enabled to prevent loops and reduce convergence time.

Use BGP with a full mesh of iBGP sessions between all branches.

Use static routes at each branch pointing to the data center, with a floating static route for backup.

Use OSPF with a two-level hierarchy, summarizing branch routes into the core and using ECMP for redundancy.

Which Layer 3 planning consideration is most important when designing a hierarchical IP addressing scheme for a large enterprise network?

Guaranteeing that every device has a public IP address

Facilitating route summarization and efficient routing

Eliminating the need for dynamic routing protocols

Ensuring that all subnets are the same size
