                          NEW QUESTION # 228
                          You wish to troubleshoot some issues that you are having on the system. You want to monitor the /var/adm/messages file in real time. Which command would you use to do this?

                          Answer: E

                          Explanation:
                          tail is a program on Unix and Unix-like systems used to display the last few lines of
                          a text file or piped data.
                          By default, tail will print the last 10 lines of its input to the standard output. With command line
                          options the number of lines printed and the printing units (lines, blocks or bytes) may be changed.
                          The following example shows the last 20 lines of filename:
                          tail -n 20 filename


                          NEW QUESTION # 229
                          Review the storage pool information:

                          Which statement describes the status of this storage pool?

                          Answer: A

                          Explanation:
                          Device c3t6d0 is not included in the RAIDZ storage pool. The other three devices are included in the raidz pool. The data on these devices are protected.
                          Note: In addition to a mirrored storage pool configuration,ZFS provides a RAID-Z configuration with either single,double,or triple parity fault tolerance. Single-parity RAID-Z (raidz or raidz1) is similar to RAID-5. Double-parity RAID-Z (raidz2) is similar to RAID-6.


                          NEW QUESTION # 230
                          Your server has a ZFS storage pool that is configured as follows:

                          The server has two spate 140-GB disk drives: c3t5d0 c3t6d0
                          Which command would add redundancy to the pool1 storage pool?

                          Answer: D

                          Explanation:
                          You can convert a non-redundant storage pool into a redundant storage pool by using the zpool attach command.
                          Note: zpool attach [-f] pool device new_device
                          Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.
                          Reference: Converting a Non-Redundant ZFS Storage Pool to a Mirrored ZFS Storage Pool
                          Reference: man zpool

                          Answer: A

                          Explanation:
