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

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

Which action cannot be done in a scripted, automated fashion using WLST?（） A: Acollecting run-time metrics and sending an email if user-defined thresholds are exceeded B: Bconfiguring Clusters and Managed Servers C: Cstarting Managed Servers using the Node Manager D: Dinstalling WebLogic binaries on a remote machine using Node Manager E: Econfiguring a Managed Server on a remote machine where the Node Manager is installed but no other Managed Servers from the domain exist

Which two characteristics are most typical of a SAN？ （） A:  NICs are used for network connectivity. B:  Servers request specific blocks of data. C:  Storage devices are directly connected to servers. D:  A fabric is used as the hardware for connecting servers to storage devices. E:  The TCO is higher because of the cost of director class storage switches.
