Which command produces human-readable timestamps in kernel ring buffer messages?
Correct Answer:
C
Explanation
The dmesg command displays kernel ring buffer messages. By default, dmesg shows timestamps in seconds since boot, which is hard to read. The -T flag converts these to human-readable format showing the actual date and time. Other options like -l filter by log level or -c clear the buffer, but neither produces readable timestamps. This question tests your ability to interpret kernel messages when troubleshooting system issues.
Which two statements are true about the Linux Auditing System?
Correct Answer:
A, B
Explanation
The Linux Auditing System tracks system events for security compliance. Audit rules can monitor file access attempts, including when administrators access user directories, which supports compliance auditing. Auditing can impact performance because logging every system call or file access requires processing and disk I/O. The system must evaluate rules against every event, and high-volume logging degrades performance. Both statements correctly describe auditing capabilities and limitations.
Which two are true about using Ksplice?
Correct Answer:
B, C
Explanation
Ksplice patches the kernel without requiring a reboot or system downtime. This is its main advantage for keeping systems current. However, when you use yum or dnf to upgrade a kernel that was previously patched with Ksplice, the package manager cannot upgrade that kernel through normal channels. You must first remove the Ksplice patches before upgrading the kernel package. This creates a management consideration for administrators using Ksplice.
Examine this command and output:
$ ftp host01.example.com
Connected to host01.example.com (192.168.40.131).
220 (vsFTPd 3.0.2)
Name (host01.example.com:oracle):
After entering a carriage return, this error message is displayed:
530 Permission denied
Login Failed
ftp>
Why is the oracle user denied access to the FTP server on host01.example.com?
Correct Answer:
D
Explanation
The FTP error 530 Permission Denied occurs when authentication fails. The vsftpd server maintains a file called ftpusers in /etc/vsftpd that lists users explicitly forbidden from FTP access. This is a security feature to prevent certain system accounts from logging in via FTP. Even if the oracle user provides the correct password, if that username appears in ftpusers, the server rejects the login. The oracle user likely appears in this deny list on host01.
Which two statements are true about container technology?
Correct Answer:
C, D

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.
