What two situations could require the use of multiple routing protocols? (Choose two) Select 2 response(s).
A.
when using UNIX host-based routers
B.
when smaller broadcast domains are desired
C.
because having multiple routing protocols confuses hackers
D.
when migrating from an older Interior Gateway Protocol (IGP) to a new IGP
E.
when all equipment is manufactured by Cisco
F.
when there are multiple paths to destination networks
Answer: D,E
Ac
Explanation:
Simple routing protocols work well for simple networks, but networks grow and become more
complex. While running a single routing protocol throughout your entire IP internetwork is
desirable, multiprotocol routing is common for a number of reasons, including company mergers,
multiple departments managed by multiple network administrators, multivendor environments, or
simply because the original routing protocol is no longer the best choice. Often, the multiple
protocols are redistributed into each other during a migration period from one protocol to the other.

A and D is correct.
E is wrong since if all equipment is from Cisco there is no need for multiple routing protocols > just EIGRP
Multiple routing protocols may be necessary in the following situations:
•When you are migrating from an older interior gateway protocol (IGP) to a new IGP. Multiple redistribution boundaries may exist until the new protocol has completely displaced the old protocol.
•When the use of another protocol is desired, but the old routing protocol is needed for host systems. This is common in environments with UNIX host-based routers running RIP.
•Some departments might not want to upgrade their routers to support a new routing protocol.
•In a mixed-router vendor environment, you can use a routing protocol specific to Cisco, such as EIGRP in the Cisco portion of the network, and a common standards-based routing protocol, like OSPF, to communicate with devices from other vendors.
