How we research and review these pages
Examine this content from /etc/chrony.conf:
...
pool pool.ntp.org offline
driftfile /var/lib/chrony/drift
keyfile /etc/chrony.keys
...
Which statement is true about pool.ntp.org?
Correct Answer:
D
Explanation
The chrony daemon reads pool.ntp.org from the configuration file but does not automatically start polling it. You must use chronyc commands to enable the polling. The pool line syntax is correct, showing an offline pool that requires explicit activation. Other options might suggest automatic operation or incorrect configuration, but chrony specifically requires chronyc intervention before polling begins on configured pools.
Which command configures a fully functional and accessible interface on VLAN 800?
Correct Answer:
C
Explanation
Configuring a VLAN requires three distinct steps that must happen in order. First, load the 8021q kernel module with modprobe to enable VLAN support. Second, create the virtual interface using ip link with the VLAN ID 800 on the physical interface eth0. Third, assign an IP address and bring the interface up. Answer C performs all three steps correctly in the proper sequence. Other options would be incomplete or use incorrect syntax for any of these operations.
Examine this command:
$ podman run --name=oracleshell -it oraclelinux:8 -slim
Which two statements are true upon execution?
Correct Answer:
A, D
Explanation
The logrotate utility manages log files to prevent them from consuming excessive disk space. It performs two main actions on log files. First, it rotates them, which means it renames the current log file and creates a new one for the system to write to going forward. Second, it compresses old rotated log files using gzip to reduce their size on disk. Other options mentioning deletion of logs or direct writing to remote servers are not standard logrotate functions. The utility simply manages files locally on the system according to configuration rules you set.
Which takes precedence for ssh program configuration?
Correct Answer:
C
Explanation
The ssh minus L command creates a local port forward from your machine to a remote machine through an SSH tunnel. In this example, local port 5011 forwards connections to 127.0.0.1 port 80 on the remote server at 10.10.2.20. The minus f flag forks the SSH process into the background, letting you keep using your shell. The connection stays open for the duration specified by sleep 30. This is useful for securely accessing remote services as if they were local. Remote port forwarding would use minus R instead, and dynamic forwarding uses minus D.
Which two default user account settings are contained in /etc/login.defs?
Correct Answer:
D, E
Explanation
The /etc/login.defs file stores default settings for user account creation and password policy. It contains password aging controls like PASS_MAX_DAYS, PASS_MIN_DAYS, and PASS_WARN_AGE. It also specifies the encryption method used when hashing passwords with algorithms like SHA512. The file does not control current login sessions, PAM stacks, or individual user passwords. It sets system-wide defaults that apply when new accounts are created or passwords are changed through standard tools.
Which two statements are true about the Oracle Linux 8 boot process?
Correct Answer:
A, D
Explanation
The Oracle Linux 8 boot process follows a specific sequence. GRUB 2 loads the initramfs file into memory and extracts vmlinuz into a temporary RAM-based filesystem. The kernel then loads essential driver modules from the initramfs to access the actual root filesystem on disk. Without these drivers loaded early, the system cannot mount and read from the real root partition. The other options might mention correct components but describe incorrect sequences or operations during the boot process.
Which three statements are true about the journalctl command?
Correct Answer:
B, D, E
Explanation
The journalctl command offers specific filtering options for different logging needs. The -p flag filters by priority level where err shows error level only, and -p 6 shows info level and above since info is priority 6. The -k flag displays only kernel messages from the current boot session. These are standard journalctl options used to query systemd-journald logs. Other priority levels or flags would produce different output than what these specific options deliver.

FAQ
1Z0-106 Exam FAQ
Common questions about the exam itself
What experience level do I need to take the 1Z0-106 exam?
This exam targets experienced Linux system administrators working with Oracle Linux 8 in production environments. You should have substantial hands-on experience managing Linux systems, not just database administration knowledge. The exam assumes you work daily with system administration tasks like package management, user administration, and storage configuration.
How does 1Z0-106 relate to other Oracle Linux certifications?
The 1Z0-106 exam is part of the Professional Oracle Linux 8 System Administrator certification path. It represents the advanced level and follows the associate-level Linux certification. Passing this exam qualifies you for the Professional credential.
Which objective area of 1Z0-106 do most candidates struggle with?
Storage management and Linux security tend to challenge most candidates because they require both conceptual understanding and hands-on practice. SELinux configuration, LVM setup, and software RAID management involve multiple interrelated components. Spend extra time in labs practicing Logical Volume Manager operations and SELinux troubleshooting.
How long should I plan to study for 1Z0-106?
Most candidates with solid Linux administration experience need 4 to 8 weeks of focused study. If you are working with Oracle Linux daily, you may need less time. Allocate specific weeks to practice labs for complex areas like cgroups, PAM configuration, and advanced networking.
What happens on exam day for 1Z0-106?
You will answer 60 multiple-choice questions within 90 minutes. Your score displays immediately after completion, and you receive an email confirmation within 24 hours. You can also view your detailed score report in Oracle CertView to identify topic areas where you performed well or poorly.
Can I retake the 1Z0-106 exam if I fail?
Yes, you can retake the exam. However, you must wait a specified period between attempts and purchase a new exam voucher. Oracle typically enforces a waiting period between failures to ensure candidates have time to study additional material.
How long does the Professional Oracle Linux 8 System Administrator certification last?
Oracle certifications generally remain valid for three years from the date you earn them. After three years, you must renew by passing a current version of the exam or completing renewal requirements specified by Oracle.
What job roles does 1Z0-106 prepare me for?
This certification is designed for Linux system administrators, site reliability engineers, and infrastructure engineers working in enterprise environments. Employers value this credential for roles managing Oracle Linux systems, particularly in organizations running Oracle databases and enterprise applications.
Does 1Z0-106 cover Oracle database administration topics?
No, this exam focuses exclusively on Oracle Linux system administration skills. While the Linux skills are essential for supporting Oracle databases, the exam does not test database administration, SQL, or Oracle-specific application knowledge.
What tools and commands are heavily tested on 1Z0-106?
Expect heavy coverage of systemd and systemctl for service management, dnf for package management, firewalld and nftables for security, and journalctl for log management. Practical knowledge of ip, nmcli, LVM commands, and auditctl is essential. Study the real command syntax, not just concepts.
