软考 Information System Operations Administrator is a Chinese CBT qualification: knowledge MCQs plus an operations paper in one 240-minute sitting, 45/75 on each subject. The 2026 sitting is 23–26 May 2026. This 100-question English MCQ bank adapts OS/database/network install and run-book judgment; it is not an official paper.

Sample Ruankao Information System Operations Administrator (Junior) Practice Questions

Try these sample questions to test your Ruankao Information System Operations Administrator (Junior) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In 软考信息系统运行管理员 hardware teaching, the CPU (中央处理器) is mainly composed of which combination of units?

A.Only a GPU and a network interface card

B.Only an optical drive and a printer port

C.Arithmetic-logic unit (运算器), control unit (控制器), and registers (寄存器)

D.Only a UPS battery and a cooling fan

Explanation: A CPU contains an arithmetic-logic unit that computes, a control unit that sequences instruction fetch and execution, and registers that hold operands and control state. Peripheral devices and power hardware are outside the CPU itself. 信息系统运行管理员 candidates must know this composition when reading device performance indicators on a server spec sheet.

2Why do 软考 teaching notes place Cache (高速缓存) between the CPU and main memory?

A.To permanently archive payroll files for ten years

B.To hide the speed gap so the CPU waits less on slower DRAM

C.To replace the BIOS firmware on every boot

D.To convert analog telephone audio into IP packets

Explanation: Cache is a small, fast SRAM layer that keeps recently used instructions and data close to the CPU. It exists because DRAM main memory is much slower than the CPU, so hits in Cache cut wait states. Cache is volatile working storage, not a legal archive, firmware programmer, or voice gateway.

3A computer-room rack loses municipal AC. Which device is installed so servers can shut down gracefully instead of crashing mid-write?

A.A KVM switch with no battery

B.A USB barcode scanner

C.A DVI-to-VGA adapter

D.An uninterruptible power supply (UPS, 不间断电源)

Explanation: A UPS (不间断电源) sits on the AC feed and supplies battery (and often inverter) power during an outage long enough for an orderly OS shutdown or generator transfer. 机房 teaching also pairs UPS with dual feeds. A KVM, scanner, or video adapter does not store energy for the power rails.

4When a disk array copies a large backup image into RAM with only one setup interrupt, which I/O control method is being used?

A.Programmed polling of every byte by the CPU

B.Direct memory access (DMA, 直接存储器访问)

C.Manual DIP-switch entry of each sector

D.Serial-console copy-paste of hex dumps

Explanation: DMA lets a controller move a block between a device and main memory after the CPU programs the transfer, so the CPU is not occupied per byte. Interrupt-driven I/O still interrupts more often than a single DMA completion. Polling and manual hex entry are not how production backup arrays move bulk data.

5A 信息系统运行管理员 sees that committed processes still run when physical RAM is smaller than their total working set. Which mechanism makes that possible?

A.Virtual memory (虚拟存储器) paging idle pages to auxiliary storage

B.Disabling the system clock so time stops

C.Removing the CPU Cache so DRAM looks faster

D.Bonding two USB ports into a RAID 0 boot disk

Explanation: Virtual memory (虚拟存储器) maps a large logical address space onto RAM plus disk (pagefile/swap). Idle pages go to auxiliary storage so more processes can be resident than physical RAM alone allows. Slowing the clock, removing Cache, or USB RAID 0 does not create that address-space illusion.

6Four 1 TB disks are striped with no parity and no mirror (RAID 0). What is the correct operations judgment?

A.Usable capacity is 1 TB and any one disk failure is still fully redundant

B.Usable capacity is 4 TB, but a single disk failure loses the entire stripe set

C.Usable capacity is 3 TB because one disk is reserved for parity

D.Usable capacity is 2 TB because RAID 0 is always a mirror pair

Explanation: RAID 0 stripes data across all members with no redundancy, so usable capacity is the sum of the disks (4 × 1 TB = 4 TB). Any member failure destroys the stripe. Parity (RAID 5) and mirroring (RAID 1/10) are different layouts.

7A disk array uses RAID 5 with five equal 2 TB disks (distributed parity, one disk of capacity used for parity). What is the usable data capacity?

A.10 TB

B.2 TB

C.4 TB

D.8 TB

Explanation: RAID 5 usable capacity is (N−1) × disk size because one disk equivalent is consumed by parity. For five 2 TB disks: (5−1) × 2 TB = 8 TB. The array can survive one disk failure; it is not a 10 TB stripe and not a single-disk 2 TB volume.

8Two 1 TB disks are configured as RAID 1 (镜像). What usable capacity and fault behavior should the 信息系统运行管理员 report?

A.2 TB usable, and either disk may fail with no data left

B.0.5 TB usable because RAID 1 always quarters capacity

C.1 TB usable, and one disk may fail while the mirror still serves data

D.1 TB usable only if both disks fail together

Explanation: RAID 1 writes the same blocks to both members, so usable capacity is one disk (1 TB) and utilization is 50%. The set survives a single disk failure. It does not add the two capacities, and it does not require both disks to fail before remaining usable.

9Which computer type is the usual install target for a shared DBMS and office file service in a small organization's equipment room?

A.A battery-powered handheld barcode terminal only

B.A rack or tower server (服务器) with ECC memory and redundant PSUs

C.A consumer pocket calculator

D.A CRT television with no CPU

Explanation: Servers (服务器) are built for multi-user, always-on workloads: ECC RAM, RAID, redundant power, and remote management. 软考 hardware notes contrast them with PCs, workstations, and supercomputers. A handheld terminal, calculator, or TV is not the DBMS host.

10Compared with programmed I/O that spins waiting for a keyboard, what does interrupt-driven I/O (中断控制) allow the CPU to do?

A.Ignore all device errors forever

B.Run other processes until the device signals completion

C.Delete the interrupt controller so no device can signal

D.Replace main memory with Cache only

Explanation: Under interrupt control, the CPU is free after starting I/O; the device raises an interrupt when it needs service. That is more efficient than busy-wait polling. Interrupts do not mean errors are ignored, nor that the interrupt controller should be removed.

2Backups: distinguish full vs incremental vs differential and test restores.

3On install items, complete OS then drivers then application then baseline hardening.

4Know when to stop and call the 信息系统管理工程师 rather than improvising a schema change.

5Keep a run-book mindset: the exam rewards the documented, reversible action.
