Question No: 152 – (Topic 2)

A junior administrator is having difficulty getting a service installed and configured on a Solaris 10 OS and has asked for assistance. The service must be started automatically from inetd.

The installation script places entries appropriate to the service in /etc/inetd.conf and they are formatted correctly. The service does NOT start on demand and the administrator has issued several pkill -HUP inetd commands. This same service installs and works fine on a Solaris 9 OS. There are no problems with the binaries associated with the service. What command must be run to configure and enable this service on the Solaris 10 OS?

  1. reboot

  2. inetadm -l

  3. inetconv -e -f

  4. inetadm -e /etc/inetd.conf

Answer: C

Question No: 153 – (Topic 2)

You are configuring a system on a public network. Because of the risk of other systems snooping network traffic and obtaining login and password information that is sent in clear text, you want to force users who access this system remotely to use ssh instead of telnet. To do this, you want to disable in.telnetd. Which two commands accomplish this? (Choose two.)

  1. inetadm -d svc:/network/telnet

  2. inetd delete svc:/network/telnet

  3. svcadm disable svc:/network/telnet

  4. inetadm delete svc:/network/telnet

  5. svcadm destroy svc:/network/telnet

  6. grep -v in.telnetd /etc/inetd.conf gt; /etc/inetd.conf

Answer: A,C

Question No: 154 – (Topic 2)

Which two statements are true about the inetd process on a system running the Solaris 10 OS? (Choose two.)

  1. It only runs on servers.

  2. It is considered the master restarter.

  3. It starts well-known services on demand that are NOT automatically started at boot time.

  4. It consults /etc/inet/services to determine which service to start when a request is received on a port.

Answer: C,D

Question No: 155 – (Topic 2)

Which three statements are true about well-known ports? (Choose three.)

  1. They must be agreed upon by all users.

  2. They are listed in /etc/inet/services.

  3. They are published by the Central Authority.

  4. They change assignments between reboots.

  5. The assignments are generated on demand by the Central Authority.

Answer: A,B,C

Question No: 156 – (Topic 2)

To save time configuring some custom network facilities, a junior administrator in your company attempts to copy some entries from the /etc/inetd.conf file on a Solaris 8 OS server into the /etc/inetd.conf on a Solaris 10 OS server. The junior administrator is unable to determine why services do not start. Which two commands can you run on the Solaris 10 OS server to start the services? (Choose two.)

  1. inetconv -f

  2. inetcfg -i /etc/inetd.conf

  3. inetcfg -o /etc/inetd.conf

  4. inetconv -f -i /etc/inetd.conf

  5. inetconv -forceimport -o /etc/inetd.conf

Answer: A,D

Question No: 157 – (Topic 2)

Assuming the directory /swapdir exists, what is the result of executing the following command?

# mkfile 100m /swapdir/file1

  1. A 100 megabyte swap file named /swapdir/file1 is created.

  2. A 100 megabyte swap file named /swapdir/file1 is added to the existing swap space.

  3. The size of the existing swap partition is increased by 100 megabyte using a file named

    /swapdir/file1.

  4. This command fails, because swap space can be created only during the initial installation of the operating system.

Answer: A

Question No: 158 – (Topic 2)

You receive error messages that the /lard file system is full. You check and see that it has a large file called swapfile. Your system has more than enough swap space. You suspect that the file is in use as swap space.

Which sequence of commands confirms that the file is in use as swap space, and helps correct the file system problem?

  1. swap -r /lard/swapfile ; rm /lard/swapfile

  2. swap -l ; swap -d /lard/swapfile ; rm /lard/swapfile

  3. swap -l ; rm /lard/swapfile ; swap -d /lard/swapfile

  4. swap -l ; swap -r /lard/swapfile ; rm /lard/swapfile

Answer: B

Question No: 159 – (Topic 2)

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

  1. unassigned wm 0 0 (0/0/0) 0

  2. unassigned wm 0 0 (0/0/0) 0

  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

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.)

  1. add slice 2 as swap:

    # swap -a /dev/dsk/c0t0d0s2

  2. create a 512 megabyte swap file on the root disk:

    # mkfile 512m /swapfile

    # swap -a /swapfile

  3. remove the existing swap and read it using swap compression: # swap -d

    /dev/dsk/c0t0d0s3

    # swap -a -c /dev/dsk/c0t0d0s3

  4. 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

  5. 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

Answer: B,D

Question No: 160 – (Topic 2)
