Q42

Suppose in a web browser, you click on the $\textsf{www. gate-2023.in}\; \text{URL}$. The browser cache is empty. The $\text{IP address}$ for this $\text{URL}$ is not cached in your local host, so a $\text{DNS}$ lookup is triggered (by the local $\text{DNS}$ server deployed on your local host) over the $3$-tier $\text{DNS}$ hierarchy in an iterative mode. No resource records are cached anywhere across all $\text{DNS}$ servers. Let $\text{RTT}$ denote the round trip time between your local host and $\text{DNS}$ servers in the $\text{DNS}$ hierarchy. The round trip time between the local host and the web server hosting $\textsf{www.gate-2023.in}$ is also equal to $\text{RTT}$. The $\text{HTML}$ file associated with the $\text{URL}$ is small enough to have negligible transmission time and negligible rendering time by your web browser, which references $10$ equally small objects on the same web server. Which of the following statements is/are $\text{CORRECT}$ about the minimum elapsed time between clicking on the $\text{URL}$ and your browser fully rendering it?
