角色	必要性	描述
IoT Engineer		Understands DNS role in IoT: cloud service name resolution, mDNS for local discovery. Configures DNS client on IoT devices.
Network Engineer	必要	Understands DNS hierarchy: root servers, TLD, authoritative, recursive resolvers. Knows main record types (A, AAAA, CNAME, MX, TXT, SRV). Can perform dig/nslookup queries.
Telecom Developer		Understands the fundamentals of DNS Deep Dive. Applies basic practices in daily work. Follows recommendations from the team and documentation.

角色	必要性	描述
IoT Engineer		Configures DNS strategies for IoT: DNS-over-TLS for security, failover DNS, caching on IoT gateway. Diagnoses DNS issues in IoT networks.
Network Engineer	必要	Configures authoritative DNS servers (BIND, PowerDNS). Implements split-horizon DNS. Diagnoses DNS problems and understands TTL, negative caching.
Telecom Developer		Independently applies DNS Deep Dive in practice. Understands trade-offs of different approaches. Solves typical tasks independently.

角色	必要性	描述
IoT Engineer	必要	Designs DNS infrastructure for IoT platform: private DNS zones, DNS-based device routing, geo-DNS for multi-region IoT. Ensures DNS security (DNSSEC).
Network Engineer	必要	Designs highly available DNS infrastructure with anycast. Implements DNSSEC for zones. Configures DNS-based load balancing and health checking.
Telecom Developer	必要	Has deep expertise in DNS Deep Dive. Designs solutions for production systems. Optimizes and scales. Mentors the team.

角色	必要性	描述
IoT Engineer	必要	Defines DNS strategy for IoT infrastructure. Establishes naming conventions and DNS management for large-scale IoT deployments.
Network Engineer	必要	Defines DNS architecture for the organization. Makes decisions on DNS providers (Route53, Cloudflare). Manages DNS operations. This skill is critically important for successful performance in the role.
Telecom Developer	必要	Defines DNS Deep Dive strategy at the team/product level. Establishes standards and best practices. Conducts reviews.

角色	必要性	描述
IoT Engineer	必要	Defines enterprise DNS strategy for IoT. Evaluates DNS-based service discovery (Consul) and cloud-native DNS for IoT platform services.
Network Engineer	必要	Shapes DNS strategy for the platform. Researches modern DNS: DNS over HTTPS/TLS, DNSSEC adoption. Influences the organization's DNS standards.
Telecom Developer	必要	Defines DNS Deep Dive strategy at the organizational level. Establishes enterprise approaches. Mentors leads and architects.
