Company.com is adding HACMP to an existing pair of nodes. One node is using EtherChannel  with only one adapter. The other node is using regular Ethernet connection to the switch. The customer is going to increase the number of network interfaces to two for each node.  What other considerations need to be addressed in a HACMP environment？（）    Al interfaces used for HACMP heartbeats must be identical. Differences in the interfaces will cause heartbeat failure.。  The network interfaces should all be configured with the same frame type. The use of regular Ethernet frames is mandatory.。  Network interfaces for HACMP must be all the same，Ethernet or 802.3. It does not matter which，as long as they are all the same.。  HACMP can use any network interface supported by AIX. The options on the various interfaces are masked by the Ethernet switch and do not affect HACMP.。 离子饱和度 物质费用反映的是在生产过程中所耗费的物质资料，包括（）。 直接物质消耗。 间接物质消耗。 直接人工费用。 间接人工费用。 After the /etc/tunables/nextboot file has been edited, which command can be used to validate changes to the IO performance tuning settings?（） ioo -v nextboot。 ioo -c nextboot。 valcheck -f nextboot。 tuncheck -r -f nextboot。 Which of the following files should be edited so that tftpd is running with the -n option？（）  etc/services。 /etc/inetd.conf。  /etc/tftpd.conf。  /etc/rc.net。
