200-301 Question #1073: Real Exam Question with Answer & Explanation

Submitted by saadiq_pk· Mar 5, 2026Networking Fundamentals / Network Services and Protocols - understanding how DNS resolution works end-to-end, typically covered in CompTIA Network+, CompTIA Security+, or similar foundational networking certifications.

Question

Drag and Drop Question Drag and drop the steps in a standard DNS lookup operation from the left into the order on the right. Answer:

Options

Box1An endpoint submits a request for the IP address of a domain name.
Box2The DNS submits a request to the domain DNS server.
Box3The DNS receives a reply from the domain DNS server.
Box4The DNS responds to the endpoint.
Box5The DNS submits a request to a root DNS server.

Explanation

A standard DNS lookup follows a hierarchical resolution process: the endpoint first requests an IP address, the local DNS resolver checks its cache and then queries a root DNS server to find the authoritative name server for the top-level domain, next queries the domain's authoritative DNS server directly, receives the IP address reply, and finally returns that IP address to the requesting endpoint. The correct order is: Box1 (endpoint submits request) → Box5 (DNS queries root server) → Box2 (DNS queries domain DNS server) → Box3 (DNS receives reply from domain server) → Box4 (DNS responds to endpoint). This recursive/iterative resolution ensures the DNS hierarchy is followed from the top (root) down to the authoritative source before delivering the answer.
