Question No 1

Examine this extract from /etc/httpd/conf/httpd.conf for virtual hosts: <VirtualHost *:80> ServerAdmin webmaster@sute1.example.com DocumentRoot /www/docs/site1.example.com ServerName site1.example.com </VirtualHost> <VirtualHost *:80> ServerAdmin webmaster@sute2.example.com DocumentRoot /www/docs/site2.example.com ServerName site2.example.com </VirtualHost> Which three statements are true about the configuration extract?

Choose the Choices:

To connect to the website, site1.example.com must resolve to a different IP address than site2.example.com.

site1.example.com and site2.example.com can share the sameIP address.

The web server attempts a DHCP discover to assign one IP address per virtual host.

It is possible but not mandatory to have unique IP addresses for each virtual host.

The site1.example.com virtual host shares and error logs with site2.example.com.

Question No 2

Examine the code fragment from /etc/tgt/targets.conf: <target iqn.2013 - 03.com.example.mypc:1> backing - store /iSCSIsharedDisk/physDisk1.img write - cache off </target> <target iqn.2013 - 03.com.example.myps:2> backing - store / iSCSIsharedDisk/physDisk2.img initiator - address 192.0.2.105 initiator address 192.0.2.106 write - cache off </target> <target iqn.2013 - 03.com.example.mypc:3> backing - store /iSCSIsharedDisk/physDisk3.img write - cache off </target> Which statement is true?

Choose the Choices:

Only the target identified by the iqn ending with mypc:2 is visible. This target is visible to the specific clients identified by the initiator address.

The initiator - address syntax in not valid. The address value should be specified as an iqn, not an IP address. This causes an error, and only iqns ending with mypc:1 and mypc:3 are visible.

All targets are visible to prospective clients, but the target iqn ending with mypc:2 is visible exclusively to the specified IP addresses.

The initiator - address syntax is not valid. The address value must be specified as an iqn, not an IP address. The initiator - address parameters are ignored and all targets are visible without restriction.

Question No 3

Which three statements are true about an RPM SPEC file?

Choose the Choices:

It is mandatory for building a binary RPM using rpmbuild.

It is a Shell script that can be used to build a binary RPM.

It contains metadata that will be part of a binary RPM.

It contains metadata and helper scripts that are required during the build process of a binary RPM.

Question No 4

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?

Choose the Choices:

The kernel delays panic for a few seconds if a bug is encountered to allow the klogd kernel logging daemon to log the oops output.

The kernel panics if a kernel thread sleeps in the TASK_UNINTERRUPTABLE state for more than 120 seconds.

The kernel attempts to continue if a bug is encountered.

The kernel always panics if an out - of - memory condition arises.

The kernel tries to kill some memory - consuming processes to avoid a panic if an out - of - memory condition arises.

The kernel panics if a user thread sleeps in the TASK_UNINTERRUPTABLE state for more than 120 seconds.

Question No 5

Which two options prevent unauthorized access to the named service from the rndc utility on Oracle Linux?

Choose the Choices:

running rndc - confgen – a to generate a key that can be used by both the named service and the rndc utility

running rndc - confgen – a to generate a key that can be used only by the named service

running rndc – k /etc/rndc.key to generate a key to be used only by the rndc utility

the presence of /etc/named.conf with the line include “/etc/rndc.key”; to allow the named service to check for a matching key from the rndc utility
