第二部分:核心产品技术要点与典型考题
2.1 云服务器CVM详解
技术要点: 腾讯云CVM(Cloud Virtual Machine)是计算服务的核心产品,支持多种实例规格和操作系统。
典型考题1:
问题:某企业需要部署一个高可用的Web应用,要求能够自动应对服务器故障,并且支持弹性扩容。以下哪种方案最合适? A. 单台CVM + 云硬盘 B. 多台CVM + 负载均衡 + 自动伸缩组 C. 多台CVM + 云数据库 + 手动扩容 D. 单台高配CVM + 云监控
答案解析: 正确答案是 B。理由如下:
- 多台CVM:提供冗余,避免单点故障
- 负载均衡:分发流量,提高可用性
- 自动伸缩组:根据业务负载自动调整实例数量,实现弹性扩容
代码示例:使用Terraform配置自动伸缩组
# 定义启动模板
resource "tencentcloud_as_scaling_config" "web_config" {
configuration_name = "web-server-config"
image_id = "img-9qabwv77"
instance_types = ["S5.MEDIUM4"]
instance_charge_type = "POSTPAID_BY_HOUR"
data_disk {
disk_type = "CLOUD_PREMIUM"
disk_size = 50
}
internet_max_bandwidth_out = 10
password = "YourPassword123!"
}
# 定义伸缩组
resource "tencentcloud_as_scaling_group" "web_group" {
scaling_group_name = "web-server-group"
configuration_id = tencentcloud_as_scaling_config.web_config.id
max_size = 10
min_size = 2
vpc_id = "vpc-xxxxxx"
subnet_ids = ["subnet-xxxxxx"]
load_balancer_ids = [tencentcloud_clb_instance.web_clb.id]
health_check_type = "CLB"
}
# 定义伸缩策略
resource "tencentcloud_as_scaling_policy" "cpu_high" {
scaling_group_id = tencentcloud_as_scaling_group.web_group.id
policy_name = "cpu-high-policy"
adjustment_type = "CHANGE_IN_CAPACITY"
adjustment_value = 2
cooldown = 300
metric_condition {
metric_name = "CPUUtilization"
calc_type = "MAX"
calc_period = 60
threshold = 80
condition = ">"
}
}
典型考题2:
问题:CVM实例支持哪些计费模式?各自适用于什么场景?
答案解析: 腾讯云CVM支持三种主要计费模式:
包年包月(Prepaid):
- 适用场景:长期稳定业务、预算控制严格的企业
- 优点:价格优惠(通常比按量计费便宜30%-50%)
- 缺点:灵活性差,提前支付费用
按量计费(Postpaid):
- 适用场景:短期测试、临时业务、突发流量
- 优点:灵活,用多少付多少
- 缺点:单价较高
竞价实例(Spot Instance):
- 适用场景:容错性高的批处理任务、CI/CD流水线
- 优点:价格极低(通常为按量计费的10%-20%)
- 缺点:可能被回收,不适合关键业务
2.2 云数据库CDB详解
技术要点: 腾讯云数据库(Cloud Database)支持MySQL、PostgreSQL、SQL Server等多种引擎,提供高可用、备份恢复、性能监控等功能。
典型考题3:
问题:某电商平台使用腾讯云CDB for MySQL,主实例在华南地区,业务要求实现异地容灾,RPO(恢复点目标)小于1分钟,RTO(恢复时间目标)小于5分钟。以下哪种方案最合适?
答案解析: 正确答案是 跨可用区复制 + 数据库代理 + 自动故障切换。
具体实现方案:
- 主实例:部署在华南一区
- 只读实例:部署在华南二区,开启半同步复制
- 数据库代理:使用腾讯云数据库代理,自动路由读请求到只读实例
- 监控告警:配置云监控,检测主实例健康状态
- 自动切换:使用自定义脚本或腾讯云API实现自动故障转移
代码示例:Python实现自动故障转移逻辑
import tencentcloud
from tencentcloud.common import credential
from tencentcloud.cdb.v20170320 import cdb_client, models
import time
import logging
class CDBFailoverManager:
def __init__(self, secret_id, secret_key, region):

self.logger = logging.getLogger(__name__)
def check_instance_health(self, instance_id):

req.InstanceId = read_instance_id
req.NewName = f"promoted-master-{int(time.time())}"
try:
# 注意:实际提升操作需要调用特定API,这里仅为示例
# 真实API可能需要先停止复制,然后提升为主实例
self.logger.info(f"开始提升只读实例{read_instance_id}")
# self.client.RenameDBInstance(req)
return True
except Exception as e:
self.logger.error(f"提升实例失败: {e}")
return False

"""更新DNS或数据库代理配置"""
# 这里应该调用CLB或数据库代理API更新配置
self.logger.info(f"更新路由指向新主实例{new_master_id}")
pass
def failover(self, master_id, read_id):
"""执行故障转移流程"""
self.logger.info("开始故障转移流程")
# 1. 检查主实例是否真的故障
if self.check_instance_health(master_id):
self.logger.info("主实例正常,无需转移")
return True
# 2. 提升只读实例
if not self.promote_read_instance(read_id):
self.logger.error("提升只读实例失败")
return False
# 3. 更新路由配置
self.update_dns_or_proxy(read_id)
self.logger.info("故障转移完成")
return True
# 使用示例
if __name__ == "__main__":
manager = CDBFailoverManager(
secret_id="your-secret-id",
secret_key="your-secret-key",
region="ap-guangzhou"
)
# 主实例ID和只读实例ID
master_id = "cdb-xxxxxx"
read_id = "cdb-readonly-xxxxxx"
# 执行故障转移
manager.failover(master_id, read_id)
2.3 对象存储COS详解
技术要点: 腾讯云对象存储(Cloud Object Storage)提供海量、安全、低成本的存储服务,支持静态网站托管、大数据分析、归档存储等多种场景。
典型考题4:
问题:某视频网站使用腾讯云COS存储用户上传的视频文件,文件总量超过100TB,访问模式为:最近3个月的视频访问频繁,3个月前的视频很少访问。如何设计存储方案以优化成本?
答案解析: 这是一个典型的成本优化问题,正确答案是 生命周期管理 + 分层存储。
具体方案:
- 标准存储:存储最近3个月的视频,提供低延迟访问
- 低频存储:存储3-12个月的视频,降低存储成本
- 归档存储:存储12个月以上的视频,成本最低
- 自动转换:使用生命周期规则自动转换存储类型
代码示例:使用Python SDK配置生命周期规则
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client
import sys
import logging
# 配置日志
logging.basicConfig(level=logging.INFO, stream=sys.stdout)
# 初始化客户端
secret_id = 'your-secret-id'

第三部分:网络与安全专项训练
3.1 私有网络VPC详解
技术要点: 腾讯云私有网络(Virtual Private Cloud)是构建云上网络的基础,支持自定义网段划分、路由策略、网络ACL等。
典型考题5:
问题:某企业需要在腾讯云上部署一个三层架构的应用(Web层、App层、DB层),要求各层之间网络隔离,且只能通过指定端口通信。如何设计VPC方案?
答案解析: 这是一个经典的网络架构设计题,正确答案是 多子网 + 网络ACL + 安全组。
架构设计:
VPC (10.0.0.0/16)
├── 子网1 (Web层): 10.0.1.0/24
│ ├── 安全组: 允许80/443入站,允许App层子网出站
│ └── 网络ACL: 允许HTTP/HTTPS入站,拒绝其他
├── 子网2 (App层): 10.0.2.0/24
│ ├── 安全组: 允许Web层子网8080入站,允许DB层子网3306出站
│ └── 网络ACL: 允许Web层子网入站,允许DB层子网出站
└── 子网3 (DB层): 10.0.3.0/24
├── 安全组: 只允许App层子网3306入站
└── 网络ACL: 允许App层子网入站,拒绝所有出站(除备份)

4.2 微服务治理
技术要点: 微服务架构需要解决服务发现、配置管理、熔断降级、限流等治理问题。
典型考题8:
问题:在微服务架构中,如何实现服务间的熔断和降级?请结合腾讯云TSF(微服务引擎)说明。
答案解析: 熔断降级是微服务治理的核心功能,防止级联故障。
实现方案:
- 熔断器模式:当服务调用失败率达到阈值时,自动熔断
- 降级策略:熔断后返回默认值或缓存数据
- 限流:控制并发请求量
- 超时控制:防止长时间等待
代码示例:使用Python实现熔断器
