Review Questions and Answers

1.	You are the Solaris administrator for your network. You have just configured a new server. One of your other administrators asks why slice 2 is larger than the other slices on the server's system disk. What do you tell him? Slice 2 represents the whole hard disk. Slice 2 holds the root file system and therefore needs the most space. Slice 2 is empty space, and you have not created a file system on it yet. Slice 2 holds user-created files, and because this is a file server, it needed to be the largest slice.
2.	You are the Solaris administrator for your network. Recently, you installed a new network adapter in one of your Solaris servers. The system is not recognizing the card. What is the best course of action to take? Run the cfgadm command to detect the network adapter. Run the devfsadm command to detect the network adapter. Contact Sun for a device driver for the network adapter. Contact the manufacturer of the network adapter for a device driver.

11.	You are the Solaris server administrator for your company. On one of your server's hard disks, you want to make a slice used to store user-created files larger. What is the best way to accomplish this? Use the format command to expand the size of the slice. Back up the existing data. Use the format command to delete the slice and then re-create a larger slice. Restore the data from backup. Back up the existing data. Use the format command to expand the slice. Restore the data from backup. Slices cannot be resized in Solaris.
12.	You are at the partition menu of the format command. You just caused the following information to be displayed: partition> XXXXXXXXX Current partition table (original): Total disk cylinders available: 38790 + 2 (reserved cylinders) Part Tag Flag Cylinders Size Blocks 0 root wm 1041 - 5169 1.98GB (4129/0/0) 4162032 1 swap wu 0 - 1040 512.37MB (1041/0/0) 1049328 2 backup wm 0 - 38789 18.64GB (38790/0/0) 39100320 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 home wm 5170 - 38787 16.16GB (33618/0/0) 33886944 partition> What command did you type to retrieve the displayed information? print label display select name modify

15.	You are the Solaris server administrator for your company. One of your servers has two hard disks. The first disk, disk 0, contains slices 0, 2, and 6. The second disk, disk 1, contains slices 2, 4, and 7. What is another name for disk 0? The boot disk The main disk The system disk The non-system disk
16.	You are the Solaris administrator for your company. You just received a new workstation and have powered it on. You want to see the parameters of the computer's single hard disk, including the dimensions and allocated partitions. Which command should you type to see this information? prtvtoc /dev/rdsk/c0t0d0s2 prtconf /dev/rdsk/c0t0d0s2 dispdsk /dev/rdsk/c0t0d0s2 dmesg /dev/rdsk/c0t0d0s2

19.	You are the Solaris administrator for your company. You are creating new slices on a hard disk. One of your senior administrators has advised you to choose an option she calls "All Free Hog" when beginning to slice the hard disk. What is the purpose of the free hog? The free hog is another name for the slice that contains the root file system and is used as a base for the partitioning process. The free hog is a temporary slice used by the format command to keep track of free space on the disk during the partitioning process. The free hog refers to the entire hard drive and is used as a base for the partitioning process. The free hog refers to a newly created slice that does not yet have a file system defined on it. When a file system is created on the slice, the slice is a full hog.
20.	You are a Solaris administrator. You need to find a list of device instance names for your system. In which file will you find instance names of configured devices in Solaris 9? /etc/path_to_inst /etc/instance /etc/inst /path_to_inst /instance /inst

Answers

1.	A. By convention, slice 2 represents the whole hard disk.
2.	D. If hardware is not being recognized by Solaris, it's likely that the proper device driver is not installed. Drivers should be obtained from the hardware manufacturer. The cfgadm command manages hot-swappable parts, and devfsadm manages the /devices and /dev directories, but neither one detects hardware.
3.	B. This is output from the prtvtoc command. The device listed in the first line is /dev/ rdsk/c0t0d0s2, so the correct answer is prtvtoc /dev/rdsk/c0t0d0s2.
4.	A, B. The two files that compose the kernel are /platform/`uname -m`/kernel/unix and /kernel/genunix. The /etc/system file can be used to modify the loading of kernel modules. The /etc/kernel file does not exist.
5.	B. To scan the disk for sector damage, you need to analyze the disk for errors. In contrast, format formats a disk, defect shows the manufacturer's defect list, show translates disk addresses, and verify reads and displays disk labels.
6.	A, C, E. The dmesg, prtconf, and sysdef commands can be used to display system hardware. The prtvtoc command shows a hard disk's label, or Volume Table of Contents. The sysconf command gets a list of configurable system variables. The disphw command does not exist.
7.	B. This is the partition submenu from the format command. Before taking the test, you should recognize this menu.
8.	C. The /dev/dsk directory contains logical block disk names, and /dev/rdsk contains logical raw disk names. One way to remember this is that the r in rdsk stands for raw.
9.	A, B, C, D. Each disk slice can contain only one file system, file systems cannot span multiple slices, and slices cannot span multiple disks. Multiple swap slices are allowed. Slices cannot be resized dynamically. To resize a slice, you must delete it and re-create it.
10.	B. The cfgadm command is used to manage hot-swappable parts in Solaris. The dmesg command displays hardware configuration. The devfsadm command manages the /devices and /dev directories. The hswap command does not exist.
11.	B. To make a slice larger, you must delete the slice and re-create a larger one. If there is no more disk space, then you must delete another slice to free space for your new, larger slice.
12.	A. At the partition menu, the print command displays current partition table information.
13.	A. Slice 0 is for the root file system. Slice 2 represents the whole disk. Slice 4 is an optional slice. Slice 7 typically contains user home directories.
14.	C. The cfgadm command, which configures hot-swappable devices, refers to the individual parts as the occupant and the receptacle. The receptacle is the bay on the computer, and the occupant is the device that plugs into the receptacle.
15.	C. If your computer has multiple hard disks, the disk with slice 0 and the /usr file system (which is generally located on slice 0 or 6) is known as the system disk. The disk is bootable and can be considered the main disk, but its technical term is system disk. Disk 1 in this example would be a non-system disk, because it does not contain slice 0 and the /usr file system.
16.	A. The prtvtoc command displays the disk's label, also known as the disk's Volume Table of Contents (VTOC). The label shows disk dimensions and partitions. The prtconf and dmesg commands show system device configuration information. The dispdsk command does not exist.
17.	B. dmesg displays system diagnostic messages. Although prtconf and sysdef do display hardware devices, they do not display diagnostic messages. The cfgadm command is used to manage hot-swappable hardware.
18.	D. This is the format menu. Before taking the test, make sure you recognize this menu and know what each selection does.
19.	B. When using the format utility, the free disk space is occupied by the free hog. If you delete additional slices, the free hog will "hog" the new free space. If you create additional slices, the free hog will "free" space to use for the new slice. Choosing "All Free Hog" essentially wipes out all existing slices, enabling you to start over and completely customize your hard disk partitioning structure.
20.	A. The /etc/path_to_inst file maintains mappings of all devices to instance names in Solaris 9. None of the other files exist.
