There are five Scalability Types: ____________________, ____________________, ____________________, ____________________, ____________________.

Scalability refers to the decision of whether a firm should rent or buy enterprise software packages.

Which of the following server clusters offers increased availability， performance， and scalability？（） A:  Passive/active B:  Active/passive C:  Passive/passive D:  Active/active

Which type of IGP should you use to achieve scalability in a large enterprise network？（） A: link-state protocol B: path-vector protocol C: Bellman-Ford protocol D: distance-vector protocol

AWS云中的系统被设计成能够承受一个或多个组件的故障。这是什么例子？（） A: Elasticity B: Highavailability C: Scalability D: Agility

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 E: Supported applicatio

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 E:  Supported applications

Which three factors have the biggest influence on OSPF scalability？（） A: Flooding paths and redundancy B: Amount of routing information in the OSPF area or routing domain C: Number of routers with Cisco Express Forwarding enabled D: Number of neighbor adjacencies E: Other routing protocols in use F: OSPF timer reconstruction negotiation G: Redistribution with BGP neighbors H: Redistribution with other IGP routing protocols， such as RIP or EIGRP

When scaling Coherence from one to two cache servers， it will not show the same scalability as two to four. Why？（） A:  Coherence uses a more efficient TCMP algorithm going from two to four cache servers B:  When going from one to two cache servers， object backups are copied across servers so work is doubled，but going from two to four is a fixed amount of work C:  Near cache is enabled with a larger quorum thus performance is improved D:  all of the above
