    Question



    Arrange the following steps in a proper sequence for the typical process of a DNS query:
    A. Query authoritative DNS Server
    B. Query local DNS Server
    C. Local DNS Server Check Cache
    D. Query root DNS Server
    E. Query TLD DNS Server
    Choose the correct answer from the options given below:

    A.

    A, C, E, B, D

    B.

    E, A, C, B, D

    C.

    A, B, C, D, E

    D.

    B, C, D, E, A

    Correct option is D

    In a typical DNS query:
    1. Query Local DNS Server.
    2. Local DNS Server Checks Cache.
    3. Query Root DNS Server if no cached record exists.
    4. Query TLD DNS Server to get the domain extension.
    5. Query Authoritative DNS Server to resolve the full domain.
    Information Booster:
    1. DNS Query Process: The DNS resolution process involves multiple steps, beginning with a local DNS check before querying higher-level servers if needed.
    2. Root DNS Server: This is the first point of contact if the domain cannot be resolved locally. It directs queries to the appropriate Top-Level Domain (TLD) server.
    Additional Knowledge:
    · Authoritative DNS Server: This server holds the definitive mappings of domain names to IP addresses.
    · DNS Caching: Local DNS servers often store results to speed up future queries for the same domain, reducing overall query time.
