On a 3550 EMI switch, which three types of interfaces can be used to configure HSRP?
(Select three)

A.
Loopback interface

B.
SVI interface

C.
Routed port

D.
Access port

E.
EtherChannel port channel

F.
BVI interface

Explanation:
This Hot Standby Router Protocol (HSRP) provides routing redundancy for routing IP traffic
without being dependent on the availability of any single router. To use this feature, you
must have the enhanced multilayer software image installed on your switch. All Catalyst
3550 Gigabit Ethernet switches ship with the enhanced multilayer software image (EMI)
installed. Catalyst 3550 Fast Ethernet switches can be shipped with either the standard
multilayer software image (SMI) or EMI pre-installed. You can order the Enhanced Multilayer
Software Image Upgrade kit to upgrade Catalyst 3550 Fast Ethernet switches from the SMI
to the EMI.
Only routed interfaces that provide access to hosts can be configured for HSRP. These
interfaces include: routed Ethernet, routed fast Ethernet, routed Gigabit Ethernet, SVI, and
EtherChannel.
