Q14. Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer?
A. Layer 3 routing between the Access and Aggregation layers facilitates the ability to span VLANs across multiple access switches, which is a requirement for many server virtualization and clustering technologies.
B. "East-west" server-to-server traffic can travel between aggregation modules by way of the core, but backup and replication traffic typically remains within an aggregation module.
C. Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.
D. Virtualization tools allow a cost effective approach for redundancy in the network design by using two or four VDCs from the same physical switch.
Answer: C
Q15. Which of the following is true regarding the effect of EIGRP queries on the network design?
A. EIGRP queries will be the most significant issue with respect to stability and convergence
B. EIGRP queries are not a consideration as long as EIGRP has a feasible successor with a next hop AD that is greater than the FD of the current successor route
C. EIGRP queries will only increase the convergence time when there are no EIGRP stubs designed in the network
Answer: A
