考题多选题Identify three reasons that explain why assigning more than one managed serve achieve better performance than running one managed server with more resources?（）AThread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources.BCurrent CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance.CBy a combination of prioritization of processes on the OS level and Work Manager in WLS, one could tune the whole environment more precisely.DAssigning more than one managed server to hardware will never bring better performance.EMore instances means more connections to databases, so one could serve more concurrent calls on the database level. This is primarily why this approach will give better performance numbers.FDepending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.正确答案：F,A解析：暂无解析

考题资料：The data a bank has stored on its servers is more valuable than the gold in its vaults. Banks enjoy a monopoly over data that has helped them get away with poor services and fend off competitors. In Europe, at least, that is all about to change with a new set of regulations, named PSD2. The rules will compel banks to share data easily with licensed third parties. Bankers in Europe complain that their profits and customer relationships are under threat. However, opening up banks, and the data they store, is good for consumers and competition, New providers will be better placed to offer all sorts of innovative services, such as a one-click option to put unspent monthly income into a pension plan. Nevertheless, some concerns about PSD2 are legitimate. In particular, it is reasonable to wonder about the privacy and security implications of sensitive financial date being shared with third parties. But banks themselves are hardly invulnerable to cyber attacks （网络攻击）.And the solutions that the European regulators propose to deal with these worries look promising. Third parties that want to use bank data will need to convince national regulators that their data defenses are solid and are subject to annual regulatory inspections. The gap between writing rules and implementing them is always large. First, consent from customers to provide access to their bank data must be gained explicitly, and the purposes of the data use should be clearly explained. Second, regulators must be very tough both in ensuring that banks open up their infrastructure and in withdrawing the licenses of third parties that break the rules. Third, regulators must also be flexible enough to allow for changes as the market evolves. Since the new entrants will not be licensed to engage in riskier financial activities——such as lending money——it makes sense to regulate them with a lighter touch. But if some Fintech providers do end up becoming systemically important, higher standards of oversight might be necessary.According to the first two paragraphs, what will banks in Europe be forced to do？A.To keep clients’ data safe. B.To close down the poor services. C.To give up their data monopoly. D.To disclose their sources of profits.答案：C解析：本题考查的是细节理解。【关键词】first two paragraphs；banks in Europe；forced【主题句】第2自然段The rules will compel banks to share data easily with licensed third party.这些规则将迫使银行与持牌第三方轻松共享数据。【解析】本题的问题是“根据前两段，欧洲银行被迫做什么?”。A选项“保持客户数据安全。”；B选项“关闭劣质服务。”；C选项“放弃他们的数据垄断。”；D选项“披露他们的利润来源。”根据主题句可知，欧洲银行被迫放弃数据垄断，与持牌第三方轻松共享数据，故选C。
