Examine the parameters shown using the sysctl command relating to panic situations:
[root@WAYOUT etc]# sysctl -a |grep panic |grep -v hung
kernel.panic = 0
kernel.panic_on_oops = 0
kernel.softlockup_panic = 0
kernel.unknown_nmi_panic = 0
kernel.panic_on_unrecovered_nmi = 0
kernel.panic_on_io_nmi = 0 kernel.panic_on_oom = 2
[root@WAYOUT etc]# sysctl -a |grep hung
kernel.hung_task_panic = 0
kernel.hung_task_chek_count - 4194304
kernel.hung_task_timeout_secs = 120
kernel.hung_task_warnings = 10
Which two statements are true about system behavior?

Which statement is true about configuring a nameserver in Oracle Linux?

Which two statements are true about recursive nameservers that are supported by Oracle Linux?

After creating empty mount point /xfs1, you execute the command:
# mkfs -t xfs -L /xfs1 -l logdev=/dev/sdd1 /dev/sdh1
Which two statements are true about the effects of executing the mkfs command?

You have an unmounted btrfs file system: # btrfs filesystem show Label: 'Btrfs' uuid: 7bfe3239-47ee-442b-b9f8-49f88b6b1be4 Total devices 3 FS bytes used 300.51MB devid2 size 4.88GB used 1.06GB path /dev/sdd devid1 size 4.88GB used 580.00GB path /dev/sdc devid3 size 4.88GB used 1.50GB path /dev/sdb You have these mounted devices: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_exam1-LogVol_system

You have a mount point for the btrfs file system:
# ls -all /btrfs
total 0
drwxr-xr-x. 1 root root 0 Aug 12 10:17 .
dr-xr-xr-x. 1 root root 276 Aug 12 10:36 ..
Examine these steps:
1.Manual defragment is not needed. Btrfs will defragment it automatically.
2.btrfs device defragment /dev/sdd
3.btrfs filesystem defragment /btrfs
4.btrfs device delete /dev/sdb /btrfs
5.mount UUID=7bfe3239-47ee-442b-b9f8-49f88b6b1be4 /btrfs
6.btrfs device delete /dev/sdb /dev/sdd
What is the correct order to delete the /dev/sdb device from the btrfs file system and for defragmenting the reduced file system?

What statement is true about udev?

<target iqn.2013-03.com.example.myps:2>
