400-007 Exam Dumps : Cisco Certified Design Expert (CCDE v3.1)

In infrastructure design, primary constraints are:

D (Component availability): If hardware or software components are not readily available, designs may need to adapt.

E (Total cost): Budget limitations always influence design decisions regarding redundancy, scalability, and technology selection.

Why other options are not primary constraints:

A: Monitoring is a design consideration, but not a core constraint.

B: Time frame impacts project delivery, not necessarily the design robustness.

C: Staff experience affects operations but is not a primary technical design constraint.

Inbound traffic engineering is best controlled by manipulating how external ASes view your routes.

AS path prepending on the 91.7.0.0/16 prefix towards AS 200 makes AS 500 prefer the less-prepended path through AS 100.

This allows granular inbound control for that specific prefix while leaving the rest of the traffic unchanged.

Why other options are incorrect:

B: Extended community is not used for direct inbound path manipulation.

C: Local preference affects outbound traffic, not inbound path selection by remote ASes.

D: MED is only compared between the same AS; it won ' t affect AS 500 ' s choice.
