Company.com has decided to implement VPN for all network traffic. How might this might affect HACMP？（）    Only the heartbeat IP network can exist in a VPN style network.。  HACMp must have separate VPN’s for all ’non-service’ and ’service’ adapter networks.。  If a VPN is used for IP traffic the heartbeating must be done over disk connections.。  HACMP can exist in a VPN network environment，but special considerations must be addressed.。 体育课程改革根本目的是（）。 Companycom is planning to do server consolidation on POWER5. The customer has a test environment, a QA environment and a production environment for two applications. Both the test and QA environments are very small and are only utilized when new releases are being developed and tested. They require less than 1 CPU each. Both production applications require 2 CPUs for day-to-day operation and can require up to an additional 2 CPUs each during abrupt peak requirements. What is the best design for the LPARs?（） Use micropartitioning for test and QA environments, and DLPAR for the production applications  。 Use micropartitioning for test and QA environment, and CPU pooling for the production applications 。 Create standard LPARs for all test, QA, and production applications to keep all partitions separate and isolated. 。 Create DLPAR partitions for all test, QA, and production applications to keep test from disturbing production environment.&e。 An administrator issued a command to update thefirmware of an Ethernet adapter on a partitioned system, but received an error. What is the most likely cause of the problem?（） The adapter must be taken offline prior to the firmware update.。 The system has not been rebooted since the adapter was added to the LPAR.。 The adapter must be assigned to the service partition prior to updating the firmware.。 The adapter must be dynamically removed from the LPAR prior to updating thefirmware.。 二十世纪六十年代由拉斯（L.Raths）教授等人提出了培养儿童道德认识的策略（） 价值澄清。 小组道德讨论。 群体规定。 协调分歧。 The data on datavg is inaccessible. Using "df" the user discovers that none of the datavg filesystems are mounted. Running "lsvg" shows only rootvg. Running "importvg -y" gives the following error: "056-056 volume cannot be varied on because pv is marked missing". Which of the following steps should be performed?（）
