An engineer is designing a Layer 3 campus network running EIGRP between the core, aggregation, and access
layers. The access layer switches will be connected to the aggregation layer using Layer 3 copper connections.
The engineer wants to improve the convergence time for access layer switch failures. Which technique must
the design include?
An engineer is designing a multicast network for a financial application. Most of the multicast sources also
receive multicast traffic (many-to-many deployment model). To better scale routing tables, the design must not
use source trees. Which multicast protocol satisfies these requirements?
