• Question 263:

  The production server needs additional swap space due to lack of physical memory. The system has only one disk and is partitioned as follows: Part Tag Flag Cylinders Size Blocks

  0 root wm 1041 - 38491 18.00GB (37451/0/0) 37750608 1 swap wu 0 - 1040 512.37MB (1041/0/0) 1049328 2 backup wm 0 - 39532 19.00GB (39533/0/0) 39849264 3 unassigned wm 0 0 (0/0/0) 0 4 unassigned wm 0 0 (0/0/0) 0 5 unassigned wm 0 0 (0/0/0) 0 6 unassigned wm 0 0 (0/0/0) 0 7 unassigned wm 0 0 (0/0/0) 0

  There is one swap slice configured and active:

  # swap -l swapfile dev swaplo blocks free /dev/dsk/c0t0d0s1 136,1 16 1049312 0 The root file system is a flat file system: # df -k / Filesystem kbytes used avail capacity Mounted on /dev/dsk/c0t0d0s0 18575269 9549546 9025723 53% /

  Which two methods can be used to temporarily add swap space? (Choose two.)

  A. add slice 2 as swap: # swap -a /dev/dsk/c0t0d0s2
  B. create a 512 megabyte swap file on the root disk: # mkfile 512m /swapfile # swap -a /swapfile
  C. remove the existing swap and read it using swap compression: # swap -d /dev/dsk/c0t0d0s3 # swap -a -c /dev/dsk/c0t0d0s3
  D. repartition the disk so that slice 3 contains the unused cylinders 38492 through 39532, and then add slice 3 as swap: # swap -a /dev/dsk/c0t0d0s3
  E. use NFS to mount a file system from the development server, and then create and use a swap file on the remote system: # mkdir /data # mount -F nfs tokyo:/export/data /data # mkfile /data/swapfile # swap -a /data/swapfile
  B. create a 512 megabyte swap file on the root disk: # mkfile 512m /swapfile # swap -a /swapfile
  D. repartition the disk so that slice 3 contains the unused cylinders 38492 through 39532, and then add slice 3 as swap: # swap -a /dev/dsk/c0t0d0s3
