Q42. Examine this command and output:
# cat deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
selector:
matchLabels:
app: nginx
replicas: 2
template:
metadata:
labels:
app: nginx
spec:
containers:
– name: nginx
image: nginx:1.14.2
ports:
– containerPort: 80
Now examine this command which executes successfully:
$ kubectl create -f deployment.yaml
Which two statements are true?

The command creates and guarantees the availability of a specified number of identical pods.

The command creates a deployment named nginx.

The command creates a pod named nginx.

The command specifies port 80 as the port that the container exposes.

The command specifies nginx image version 1.14.2 and will fail if the image version is not available.

Q43. Which is true about the /etc/sysconfig directory in an Oracle Linux 8 system?

It is used to access device and device driver information.

Files in this directory hierarchy contain information about running processes.

Its contents depend on the packages installed on the system.

Files in this directory hierarchy contain information about system hardware.

Q44. Which two statements are true about control groups (cgroups) in Oracle Linux 8?

Oracle Linux 8 implements cgroups v2 by default.

A cgroup is a collection of processes bound to a set of limits or parameters defined in the cgroups filesystem.

Different controllers from cgroups version 1 and cgroups version 2 cannot be used at the same time.

The cgroups filesystem allows limits to be overwritten in the lower levels of the hierarchy.

Cgroups allow processes to be organized into hierarchical groups whose resource usage cannot be limited and monitored.

Q45. Which two statements are true about container technology?

A container application built on a bare metal system cannot run on virtual machines or cloud instances.

A container application is dependent on the host operating system and kernel version.

Containers package an application with the individual runtime stack.

Podman, Buildah, and Skopeo are independent tools to create, run, and manage container applications across compatible Oracle Linux systems.

Podman requires a running daemon to function and to enable containers to start and run without root permissions.

Q46. Which are three of the network bonding modes supported in Oracle Linux 8?

Multicast

Round-robin

Split Horizon

802.3ad

Poison Reverse

Active Backup

Passive Backup

Q47. Examine this command:
# auditctl -w /etc/passwd -p w -k pass
Which two statements are true upon execution?

A write occurs to /etc/audit/rules.d/audit.rules.

An audit rule is defined that creates a log entry every time /etc/passwd is read.

An audit rule is defined with the keyword pass.

An audit is defined that creates a log entry every time a write occurs to /etc/passwd.

A write occurs to /etc/audit/audit.rules.

Which two are true?

A RAID device failed and has returned to normal operating status.

The RAID set read and write performance is currently sub-optimal.

A new RAID device was just added to replace a failed one.

An extra device was added to this RAID set to increase its size.

Only write performance is currently sub-optimal on this RAID set.

Q49. Which two statements are true about the GRUB 2 bootloader?

Its configuration can be changed by editing /etc/default/grub2 and executing grub2-mkconfig to regenerate grub2.cfg.

It can load many free operating systems directly and chain-load proprietary operating systems.

Its configuration file is /boot/grub2/grub2.conf on BIOS-based systems.

It understands file systems and kernel executable formats, allowing the loading of operating systems without recording the on-disk physical location of the kernel.

Q50. You must add an additional swap device and you add this entry to /etc/fstab:
/.swapfile none swap defaults 0 0
Examine these commands and output:
# dd if=/dev/zero of=/.swapfile bs=1024 count=1048576
1048576+0 records in
1048576+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 4.32499 s, 248 MB/s
# swapon -a
swapon: /.swapfile: insecure permissions 0644, 0600 suggested.
swapon: /.swapfile: read swap header failed
Which two actions must you perform to add this swap device?

Initialize the .swapfile file by using the mkswap command.

Execute swapon -all.

Change defaults to user in the /etc/fstab entry.

A local port forward is created between client and server.

A socket remains open for 30 minutes unless a connection is established.

A web server is listening on port 5011.

An SSH connection process is forked to the background.

Q53. Which three statements are true about the journalctl command?

journalctl -bl -p err fails if journal persistence is not configured.

journalctl -p err shows only error log level.

journalctl -p notice..warning shows all messages from notice to warning log level since the last boot.

journalctl -k shows kernel logs since the last boot.

journalctl -p 6 shows all info log level messages and above.

Q54. Examine these requirements for a host with a user oracle:
