CompTIA A+ Core 2(220-1102)是 A+ 认证的两场考试之一,另一场是 Core 1(220-1101)。两场都通过才能获得 CompTIA A+ 认证。Core 2 考 90 题,90 分钟,及格线 700/900,考试费 $358 USD。

Core 1 侧重硬件和网络,Core 2 侧重软件和安全。Core 2 的 4 大考试域:操作系统(Windows/macOS/Linux)、安全(恶意软件、社会工程、物理安全)、软件故障排除(应用崩溃、OS 引导问题)和运营流程(ITIL 基础、变更管理、文档)。

2025 年 CompTIA 宣布 220-1102 将在 2025 年底退役,被新版 220-1202 取代。新版增加了对 Windows 11 和云端管理(Intune/Autopilot)的考查。如果你已经开始准备 1102,建议在退役前考完。

A+ 在 IT 支持市场的地位

CompTIA A+ 是美国国防部 DoD 8570 认可的基础认证之一,政府 IT 支持合同几乎都要求 A+。在澳洲,Seek 上搜索 "CompTIA A+" 能找到 200+ 个 IT Support 职位。

Core 2 比 Core 1 更实用:Core 2 涉及的 Windows 故障排除、安全基础、命令行工具(netstat、nslookup、sfc)是 IT 支持日常工作中天天用的。

不适合考的人:已经有 2 年以上 IT 支持经验的人,直接考 Network+ 或 Security+ 对职业提升更大。

Step-by-step preparation

A concrete week-by-week plan from past test-takers — not generic advice.

1

第一阶段:Windows 操作系统(2 周)

Windows 10/11 的版本区别(Home/Pro/Enterprise)、控制面板 vs 设置、命令提示符常用命令(sfc /scannow、chkdsk、DISM)、注册表基础、组策略(gpedit.msc)。在虚拟机里实操每个命令。

2

第二阶段:安全 + 恶意软件(2 周)

恶意软件类型(病毒/蠕虫/木马/勒索软件/rootkit)的区别和清除步骤。社会工程攻击(钓鱼/尾随/shoulder surfing)。防火墙配置、BitLocker 加密、UAC 设置。

3

第三阶段:故障排除 + 运营流程(1-2 周)

CompTIA 的故障排除方法论 6 步骤必须背熟(Identify → Theory → Test → Plan → Verify → Document)。ITIL 变更管理流程、备份策略(3-2-1 规则)、事件文档记录。

4

第四阶段:PBQ 练习 + 模考(1 周)

A+ 考试包含 Performance-Based Questions(模拟操作题),比如在虚拟环境里配置 Windows 防火墙或修改注册表。做 3 套模考稳定 80% 以上。

Real test-taker experiences

What it actually took for real candidates to pass — prep time, scores, and lessons learned.

PBQ 是最让人紧张的部分 — 模拟了一个 Windows 桌面让你排查网络连接问题。建议在 VirtualBox 里装一个 Windows 反复练命令行操作。

有工作经验的话 Core 2 比 Core 1 简单很多,因为故障排除和安全这些天天在做。最容易丢分的是 Linux 命令行部分(chmod、chown、apt-get),平时不用 Linux 的要额外复习。

Study tips and common mistakes

💡

**PBQ 放到最后做**:PBQ 费时间,先做选择题,最后回来做 PBQ。系统会记住你的答案,跳过不影响。

💡

**CompTIA 的"最佳答案"逻辑**:很多题有 2 个看起来对的选项,选"最符合 CompTIA 方法论"的那个,不一定是实际工作中你会怎么做。

💡

**macOS 和 Linux 各出 5-8 题**:不要因为 Windows 题多就忽略这两个平台,Linux 命令行是高频丢分点。

⚠️

**Windows 版本功能区别** — Home 没有 BitLocker、没有 gpedit.msc、不能加域。考试喜欢问"客户需要加域,应该升级到哪个版本"。

⚠️

**恶意软件清除步骤顺序** — CompTIA 的标准顺序:断网 → 识别症状 → 启用修复环境 → 扫描清除 → 调度扫描 → 启用系统还原 → 验证功能。

⚠️

**Linux 文件权限** — chmod 755 表示 owner rwx、group rx、others rx。会考"给文件设置只有 owner 可读写"答案是 chmod 600。
