01Service operation, configuration, incidents and improvement
An information service combines people, processes, technology and supporting resources to deliver useful outcomes under agreed conditions. An inventory of servers is not a complete service description.
466 words, about 2 min02Security operations, monitoring and response
This domain is about running security as a repeatable service rather than a series of heroic acts. Questions target process ownership, change control and the operational metrics that show the programme is working.
803 words, about 4 min03Network Operating Systems, Servers and Application Services
Server-side knowledge is tested through role configuration, permissions arithmetic and storage/availability design. Expect a permission-intersection question and a RAID capacity question.
467 words, about 2 min04Operating systems, translation and concurrency
Understand the OS as a resource manager and extended machine: process management, CPU scheduling (FCFS, SJF, priority, round robin), process states and the PCB, context switching, threads versus processes, and inter-process communication. Study synchronization: critical sections, mutexes, semaphores, and deadlock's four necessary conditions (mutual exclusion, hold and wait, no preemption, circular wait).
494 words, about 2 min05Database theory, administration and recovery
Master the relational model: relations, tuples, attributes, keys (primary, candidate, foreign, composite), and integrity constraints (entity and referential). Understand normalization through 1 NF, 2 NF, 3 NF, and BCNF, and the anomalies each removes.
488 words, about 2 min06Network Layer Protocols and Routing
Addressing and routing dominate this domain: subnetting arithmetic, protocol behaviour, and the operational differences between RIP, OSPF and BGP. Expect one or two multi-step subnetting questions.
504 words, about 3 min07Security foundations, governance and Chinese context
This domain covers the vocabulary and models that every later domain assumes: what security protects, how it is decomposed, and the formal rules that describe access control. NISP Level 1 questions here are usually definitional, so precision matters more than depth.
917 words, about 5 min08Identity, access and cryptographic protection
This domain tests the identity lifecycle and the mechanisms that turn an identity into an authorised action. Expect questions that separate authentication from authorisation and that ask which access control model fits a scenario.
857 words, about 4 min09Continuity, backup and technical recovery
This domain tests continuity planning: how an organisation keeps critical services running during disruption and how it recovers afterwards. Distinguish the continuity plan from the disaster recovery plan and know the time-based metrics precisely.
