Updated а-310-200:
Q106. Which three are considered as technical constraints when identifying network requirements? (Choose three.)
A. support for legacy applications
B. bandwidth support for new applications
C. limited budget allocation
D. policy limitations
E. limited support staff to complete assessment
F. support for existing legacy equipment
G. limited timeframe to implement
Answer: A,B,F
Explanation:
Network design might be constrained by parameters that limit the solution. Legacy applications might still exist that must be supported going forward, and these applications might require a legacy protocol that may limit a design. Technical constraints include the following:
.Existing wiring does not support new technology.
.Bandwidth might not support new applications.
.The network must support exiting legacy equipment.
.Legacy applications must be supported (application compatibility).

A. network management servers
B. DHCP servers
C. Active Directory servers
D. IP SLA servers
E. web servers
Answer: A

Q109. A dynamically routed private line and a statically routed IPsec tunnel connect two offices. What routing configuration prefers the IPsec tunnel only in the event of a private line failure?
A. floating static entry
B. EIGRP variance
C. bandwidth metric
D. OSPF maximum paths
Answer: A
Q110. Which layer of the OSI model does Cisco recommend to place the enterprise network core layer, when designing a network based on its switched hierarchical design?
