單項選擇題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 nexthop 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 stubsdesigned in the network

1.單項選擇題Which of the following is true when considering the Server load-balancing design within the E-Commerce Module of the Enterprise Campus network？（）

A. Routed mode requires the ACE run OSPF or EIGRP
B. Bridged mode switches a packet between the public and the private subnets when it sees itsMAC address as the destination
C. Two-armed mode will place the SLB inline to the servers， with different client-side and a server-side VLANs
D. One-armed mode， which uses the same VLAN for the client， the ACE， and the servers， requiresa traffic-diversion mechanism to ensure the traffic return from the server passes though the ACE

2.單項選擇題Which factor is least likely to affect the scalability of a VPN design？（）

A. number of branch offices
B. number of IGP routing peers
C. remote Office and home worker throughput bandwidth requirements
D. high availability requirements

3.單項選擇題When considering the design of the IPv6 address plan for the Enterprise Campus network， whichof the following should serve as guidance？（）

A. All the IPv6 subnets should use a /32 prefix
B. Set aside /31 prefixes to support point-to-point links and loopback interfaces
C. The IPv6 address plan should be designed to support the service block model design orintegration with IPv4
D. Designate 16 subnet bits to be split up intelligently， either by OSPF area. VLAN numbering， orIPv4 mapping

4.單項選擇題When designing the routing for an Enterprise Campus network it is important to keep while of thefollowing filtering aspects in mind？（）

A. Filtering is only useful when combined with route summarization
B. It is best to filter （allow） the default and summary prefixes only in the Enterprise Edge to remotesites or site-to-site IPsec VPN networks
C. IGPs （for example EIGRP or OSPF） are superior to route filtering in avoiding in inappropriatetransit traffic through remote nodes or inaccurate or inappropriate routing updates
D. The primary limitation of router filtering is that it can only be applied on outbound updates

C. FIGRP stub routing
D. Limiting the number of EIGRP neighbor per device
