Question 1

Due to extreme system use, a Linux system requires some additional swap space. To

initialize 5GB of additional swap space, which combination of commands should be used?

A : dd if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; mkswap /tmp/swapfile; mount/tmp/swapfile

B : if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; swapon /tmp/swapfile

C : if=/dev/zero of=/tmp/swapfile bs=1024 count=5120000; mkswap /tmp/swapfile; swapon /tmp/swapfile

D : uch -5G /tmp/swapfile; swapon /tmp/swapfile

E : wap /tmp/swapfile 512000; swapon /tmp/swapfile

Answer: C

Question 3

A web application server contains 64GB of RAM and two swap partitions on normal hard

disk drives, each with a size of 64 GB. Within the last month, the average number of user

sessions on this server has grown by 20 percent. At the same time, the average usage of

RAM increased from 65 to 75 percent, while the swap space is almost not used at all. It is

expected that the number of user sessions will continue to increase by about 15 to 20

percent each month. Which of the following reactions would be appropriate in response to

these observations? (Choose two.)

A : Delay any hardware upgrade until there is a significant consumption of swap space toensure an efficient usage of the available hardware

B : Create a RAID 1 device on the two swap partitions to avoid data loss in case swapspace has to be used in the future

C : Consider the installation of an additional application server to distribute the load if theexpected growth continues over several months

D : ve the web application’s scripts and content a ram disk in order to ensure fast access and to avoid the need for swap space

E : date the hardware to increase the amount of available RAM to avoid using swap space

Answer: A,C

Question 4

connects this subnet to the Internet. What needs to be done on the client to enable it to use

the router as its default gateway? (Choose TWO correct answers.)

A : ute add default gw 192.168.0.1 eth0

B : config eth0 defaultroute 192.168.0.1

C : route add default via 192.168.0.1 dev eth0

E : ute add defaultgw=192.168.0.1 if=eth0
