The Information System Operations Administrator (信息系统运行管理员) is a junior-level Chinese professional qualification exam administered under the Ruankao (软考) national computer and software proficiency testing system. It targets people who keep systems running day to day: server and operating system operations, network and infrastructure upkeep, database maintenance and backup, security administration, monitoring and fault handling, and IT service processes. The Ruankao Information System Operations Administrator (Junior) study guide has 10 sections and about 4,044 words.
01Information System Fundamentals
Domain 1, Information System Fundamentals, tests whether you can name the parts of a system, place a component in the right layer, and perform the small calculations (address space, RAID capacity, normalization level) that appear as single-choice items. Items are usually scenario-framed: a described system must be classified, or an observed symptom attributed to hardware, software, data, procedure or network.
437 words, about 2 min02Operating System and Server Operations
Domain 2 covers installing and hardening a server, managing accounts and permissions, and reading performance data. Exam items mix command-level knowledge (which command shows what) with judgement questions (is this account handled correctly, is that resource actually exhausted).
414 words, about 2 min03Network and Infrastructure Operations
Domain 3 tests device roles, subnetting arithmetic, cabling and room limits, and layered fault isolation. Expect one subnetting question and one troubleshooting-sequence question.
391 words, about 2 min04Database Operations and Data Maintenance
Domain 4 covers backup and recovery design, routine maintenance tasks, and elementary SQL. The exam favours questions about which backup chain restores to a given moment, and about the difference between similar SQL statements.
404 words, about 2 min05Information System Security Management
Domain 5 tests access control models, the mechanics of antivirus and patch management, and the order of steps in incident handling. Judgement items ask what you do first, and what evidence you must not destroy.
405 words, about 2 min06System Monitoring, Fault Diagnosis and Troubleshooting
Domain 6 asks which metric proves a bottleneck, which troubleshooting strategy fits a symptom, and what sequence of diagnostic steps is defensible. Items often include a short timeline and expect you to spot the correlation.
376 words, about 2 min07Backup, Disaster Recovery and Business Continuity
Domain 7 tests the definitions of RPO and RTO, backup design rules, and the difference between a disaster recovery plan and a business continuity plan. Calculation items give a schedule and a failure time and ask for the data loss window.
379 words, about 2 min08IT Service Management and Operations Processes
Domain 8 tests whether you can place a situation into the correct process: incident, problem, change or configuration. The common failure is mixing incident speed with problem root-cause work.
419 words, about 2 min09Documentation, Standards and Regulations
Domain 9 checks that you keep records that would survive an audit, and that you know which standard or law governs a situation. Items are often compliance-judgement questions rather than definitions.
383 words, about 2 min10Professional Ethics and Comprehensive Application
Domain 10 combines case-based practice with professional ethics. A scenario is described, sometimes with a timeline, and you must choose the correct process, the correct order of actions, and the ethically defensible option.
