An Enhanced Journeyed File System that is in a shred non-concurrent Volume Group is growing at an unexpected rate. It is the administrator’s task to enlarge the filesystem without interrupting service.
What method should be sued to achieve this goal？（）

A . Use HACMP C-SPOC to increase the size of the JFS2 filesystem.
B . Use the smitty jfs2 fastpath to increase the size of the JFS2 filesystem.
C . Use HACMP C-SPOC to increase the size of the JFS2 filesystem and inline JFS2 logs.
D . Use mklvcopy hdisk# 2 jfs2lvname to increase the size of the JFS2 filesystem，then use splitlvcopy jfs2lvname 1 -y newjfs2lvname hdisk# to present the increased JFS2 filesystem to HACMP.

Which of the following statements is used to prevent user TOM from adding and deleting data in table TAB1?（） REVOKE ADD, DELETE FROM USER tom ON TABLE tab1。 REVOKE ADD, DELETE ON TABLE tab1 FROM USER tom。 REVOKE INSERT, DELETE FROM USER tom ON TABLE tab1。 REVOKE INSERT, DELETE ON TABLE tab1 FROM USER tom。假定一个拥有一亿人口的大国和百万人口的小国人口的居民年龄的差异程度相同，现在各自用重复的抽样方法抽取本国的1%人口计算平均年龄，则平均年龄抽样标准误差（）。不能确定。两者相等。前者比后者大。前者比后者小。 Table TAB1 was created using the following statement: CREATE TABLE tab1 (c1 INT, c2 INT, c3 INT, c4 INT, c5 INT); If column C1 is unique and queries typically access columns C1, C2 and C3 together, which statement(s) will createindex(es) that will provide optimal query performance?（） CREATE UNIQUE INDEX xtab1 ON tab1 (c1); CREATE INDEX xtab2 ON tab1 (c2) INCLUDE (c3) 。 CREATE UNIQUE INDEX xtab1 ON tab1 (c1) INCLUDE (c2, c3) 。 CREATE UNIQUE INDEX xtab1 ON tab1 (c3, c2, c1) 。 CREATE UNIQUE INDEX xtab1 ON tab1 (c2) INCLUDE (c1, c3)。 A server will not boot and the administrator needs to run fsck on the filesystems to verify their integrity. Installation media and diagnostic media is unavailable and there is no NIM master defined in this environment. How would the administrator bring the system up to be able to run fsck on all the filesystems？（） Boot from the IBM Disaster Recovery boot server thru the network.。 Installation media or diagnostics media is required to acquire the rootvg.。 Boot to maintenance mode， enter a limited function shell， and execute getrootfs hdisk0.。 Hold space bar at boot time to automatically initiate a limited function shell， then enter getrootfs hdisk0.。元认知
