You are the Cisco Network Designer. Which is not major scaling, sizing, and performance consideration for an IPsec design?
A.
connection speed
B.
number of remote sites
C.
features to be supported
D.
types of devices at the remote site

I belive the answer is abs wrong. the correct answ should be D
You can always scale speed on tunnel interface that’s why it is not major scaling, sizing, and performance consideration for an IPsec design.
Types of devices at the remote site actually are very important for design.

Scaling, Sizing, and Performance
The task of scaling large IPsec VPNs while maintaining performance and high availability
is challenging and requires careful planning and design. Many factors affect scalability of
an IPsec VPN design, including the number of route sites, access connection speeds,
routing peer limits, IPsec encryption engine throughput, features to be supported, and
applications that will be transported over the IPsec VPN
In reverse, if you look at major scaling, sizing, and performance consideration for an IPsec design are;
number of route sites
access connection speeds
routing peer limits
IPsec encryption engine throughput
features to be supported
applications that will be transported over the IPsec VPN
“types of devices at the remote site” is not a major factor.
Tricky. I am sticking with A. VPN scalability seems to depend more heavily on PPS than bandwidth alone. The mix of devices (e.g. VoIP phones) can influence PPS
