You are designing a small branch office that requires these attributes:
support for 60 users
the growth capacity to add another 15 users soon
redundant access
higher bandwidth between the Layer 2 switch and routing to the WAN
Which branch office topology or technology must be used?
A.
EtherChannel
B.
loop-free
C.
three-tier
D.
two-tier
E.
integrated routing and switching
There is no way the answer to this quesiton is Etherchannel. Etherchannel is about port aggregation not topology design. The design requirements in this question refer to a two-tier design which is answer D.
Fixed the correct answer. Thanks.
I agree with CCDA wannabe. Although they mention a Small Office, with the 60 users they refer to a Medium Branch using a two-tier design.
I was actually surprised that it showed EtherChannel as the correct answer.
But after some investigation in the self-study guide, they mention ether-channel under both Small and Medium office when talking about redundancy.
In fact for Small Office, they point out EtherChannel as the only option when considering redundancy and high bandwidth requirements.
check on page 357 in self-study guide 640-863
How do you add bandwidth at l2 besides EtherChannel?
Sounds like EtherChannel may be correct?
A2: Network Infrastructure
To design this small network just access layer switch is required with a WAN router. So it’s not a two layer network.
Etherchannel isn’t a topology but a technology to be used for redundancy or BW increasing between router and switch.
Etherchannel should be a correct answer

Only Large Office Design have two-tier desighn Distribution/Access, Small and Medium desighns have one-tire desighn – Access only.
