You dynamically configure a system to concurrently run tasks A1 and A2 using these commands: # mkdir /cgroup/cpu # mount -t cgroup -o cpu cpu /cgroup/cpu # mkdir /cgroup/cpu/A1 # mkdir /cgroup/cpu/A2 # echo 5 > /cgroup/cpu/A1/cpu.shares # echo 5 > /cgroup/cpu/A2/cpu.shares # mkdir /cgroup/cpuacct # mount -t cgroup -o cpuacct cpuacct /cgroup/cpuacct You want to generate a /etc/cgconfig.conf configuration fail that contains the current cgroup
configuration on the system. Which command would you use?

• A.cgsnapshot
• B.cgclassify
• C.cgset
• D.lscgroup
• E.cgcreate

Which two statements are true about the configuration of kdump for capturing a dump image after a kernel crash?

• A.The memory used forcrashkernelis always at the same physical address.
• B.kdumpuseskexecto boot a second kernel, which then captures a dump image.
• C.kdumpuseskexecto reboot the failed kernel and then captures a dump image.
• D.kdumprequires no parameters because it is enabled by default.
• E.Thecrashkernelboot parameter must be added to thekernelline in the/boot/grub.conffile to enablekdump.

For which domain or domains does the default cache-only nameserver have a list of authoritative servers in the /var/named/named. ca file?

• A.the domains to which the local DNS servers belong
• B.the domains to which the local DHCP servers belong
• C.the domain to which the cache only nameserver belongs
• D.the root domain

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?

• A.The kernel always panics if an out-of-memory condition arises.
• B.The kernel panics if a kernel thread sleeps in theTASK_UNINTERRUPTABLEstate for more than 120 seconds.
• C.The kernel delays panic for a few seconds if a bug is encountered to allow theklogdkernel logging daemon to log theoopsoutput.
• D.The kernel tries to kill some memory-consuming processes to avoid a panic if an out-of-memory condition arises.
• E.The kernel panics if a user thread sleeps in theTASK_UNINTERRUPTABLEstate for more than 120 seconds.
• F.The kernel attempts to continue if a bug is encountered.
