Answer True or False for the following statements

Q1) NFS requires that NIS (yp) be running

Q2) Changes to the NIS database can be made on the slave server

Q3) In single-user mode, the kernel is not running

Q4) A file will be removed from the files system when the link count has become zero

Q5) When the Sun system is reset or first powered on, the screen blanks and a Sun logo is displayed along with some other information about the hardware on the console. At this point, the STOP-A key combination can be pressed to interact with the PROM code. A prompt of "ok" is offered.

Q6) RAID-0 is the referred to as "mirroring". Two (or more) partitions, all of the same size, each store an exact copy of all data, disk-block by disk-block. Mirroring gives strong protection against disk failure: if one disk fails, there is another with the an exact copy of the same data. Mirroring can also help improve performance in I/O-laden systems, as read requests can be divided up between several disks.

Q7) The super user (root) has user id 1 (one).

Q8) Using a -9 with the kill command, allows the process to trap the signal and run the signal handlers that may be associated with the process.

Q9) Only the super-user or an equivalent role can run nfsd

Q10) If field 7 of the password file is empty, csh (the C-Shell) will be used for that user account

Q11) In Solaris, the following command init 5 will reboot the system

Expert Solution

Answers for the above statements are as follows:-

Q1.-True

NFS requires the NIS(yp) be running to make sure NFS user ids are the same on the server as on the client, but using it is not mandatory as you can keep server and clients password in synch.

Q2.-True

Yes, you can made changes to NIS database on the slave server but all the changes or modifications are overwritten when master server updates them.So all changes you make are temporary.

Q3.-False

In single-user mode,kernel is required for booting as it is a core of the operating system.

Q4.-True

File will be removed from file system because when link count has becomes zero the data space of the file automatically deallocated by the operating system.

Q5.-True

Q6.-False

RAID-0 is not referred as mirroring instead of RAID-1 is referred as mirroring.

Q7.-False

The super user does not have Id 1,it always has user Id 0(zero).

Q8.-False

kill-9 sends the signal for which you cannot have signal handlers and It is a way to stop the process.

Q9.-True

Q10.-False

If field 7 of password file is empty,then sh(Bourne shell) will be used for that user account.

Q11.-False

In solaris,run levels 2,3,4 are available as multiuser system states when using the init command.

Are the following statements true or false? In each case, prove your answer. There is a strictly decreasing function f from N to N with f(0) = 100. Let f(x) and g(x) be strictly increasing functions from R to R. Then (f + g)(x) is also strictly increasing. Once again, let f(x) and g(x) be strictly increasing functions from R to R. Then (f×g)(x) is also strictly increasing.
