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

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

While copying a file to the /users file system, which is located on /dev/sdd1, you receive an error:

$ cp /etc/oratab /users/oracle cp: cannot create regular file `/users/oracle/oratab': Disk quota exceeded You examine your assigned quota as shown: $ quota -q Disk quotas for user oracle (uid 500):

Which option represents the reason for receiving the Disk quota exceeded error?

A. The oracle user has reached its block quota.

B. The oracle user exceeded its file quota five days ago.

C. The oracle user has reached a group quota limit.

D. The /users file system is full.

E. The oracle user exceeded its block quota six days ago.

Consider the features of virtualization modes. Which three statements are correct?

A. With full virtualization (FV), all aspects of a guest OS are virtualized. The guest OS running on a virtual machine (VM) can run unmodified.

B. With paravirtualization (PV), the paravirtualized guests run a modified version of the guest OS, which communicates with the hypervisor by using hypercalls.

C. PV takes advantage of the virtualization hardware extensions offered by the physical server. These hardware extensions are required to run paravirtualized VMs.

D. Xen is a type-2 hypervisor that allows guests to run either as fully paravirtualized (PV guests) or as hardware virtualized (HVM guests), with or without paravirtualized drivers.

E. The Oracle Linux Unbreakable Enterprise Kernel (UEK) is a PVOPS kernel that contains all paravirtualized drivers and can determine whether the underlying system supports FV or PV operations.

Which three statements are true about an OpenLDAP server?

A. /etc/openldap.conf is the main configuration file for the LDAP server.

B. LDAP entries are stored in a flat namespace.

C. It can be used to store users and groups.

D. In can be used to store hostnames and their IP addresses.

E. It can replicate entries synchronously to another OpenLDAP server.

Which two statements are correct about features and capabilities of virtualization in Oracle Linux?

A. Virtualization is restricted to running a guest operating system in a virtual machine.

B. Virtualization permits the creation of virtual environments by using Linux Containers or Kernel Virtual Machine (KVM).

C. An I/O path from a host server to a peripheral device can be virtualized, enabling multiple guest VMs to share an I/O device.

D. A type-1 hypervisor, also known as a host-based hypervisor, is designed to run within a traditional operating system.

E. A type-2 hypervisor communicates directly with the computer hardware and as known as a bare-metal hypervisor.

Which two occur when you run the command:

[root@FAROUT /root] rndc reload

A. They key file /etc/rndc.key is reloaded.

B. The configuration file /etc/named.conf is reloaded.

C. Only new zones are reloaded.

D. All zones are reloaded.

E. Only changed zones are reloaded.

F. Only new keys are reloaded.

G. All keys are reloaded.

Which two statements are true about the cpuset cgroup subsystem?

A. It assigns individual CPUs and memory nodes for NUMA-enabled architectures to cgroup tasks.

B. It assigns individual CPUs on a multicore system to cgroup tasks.

C. It controls CPU scheduling according to relative CPU shares of cgroup tasks.

D. It reports the total CPU time used by cgroup tasks.

Which three statements are true about conversion to btrfs file systems? (Choose two.)

A. If you roll back a btrfs conversion, you lose any changes that you made to the btrfs file system.

B. You must run fsck to check and correct the integrity of the file system before converting it to btrfs.

C. You can convert a bootable partition, such as /boot, to a btrfs file system.

D. Converting the root file system is not possible by using the btrfs convert utility.

E. If you delete the snapshot of an original file system to save storage space, you can still recover the original file system.

F. The btrfs-convert utility converts an ext2, ext3, or ext4 file system to btrfs.

What is the purpose of the in-addr.arpa domain that is used in a zone file for DNS name resolution in Oracle Linux?

A. to implement reverse name resolution for IPv4

B. to resolve nameserver names in the in-addr.arpa top-level domain

C. to implement reverse name resolution for IPv6

D. to resolve host names in the in-addr.arpa top-level domain

Which three statements are true about crash utility in Oracle Linux? (Choose three.)

A. The GNU debugger must be installed separately to enable any source code dedugging features to work.
