1. A web page is 5 MB in size. If the internet speed is 20 Mbps, how long will it take to download the page using HTTP?
a) 1.5 seconds
b) 2 seconds
c) 2.5 seconds
d) 3 seconds
💡 Hint: 1 MB = 8 Megabits
Answer:
b) 2 seconds
Time=(5×8) Mbps20 Mbps=2 sec\text{Time} = \frac{(5 \times 8) \text{ Mbps}}{20 \text{ Mbps}} = 2 \text{ sec}Time=20 Mbps(5×8) Mbps​=2 sec
2. An HTTPS handshake introduces an additional 50 ms latency. If an HTTP request normally takes 200 ms, what is the new response time?
a) 200 ms
b) 225 ms
c) 250 ms
d) 300 ms
Answer:
c) 250 ms
200+50=250200 + 50 = 250200+50=250 ms
3. If an HTTP connection requires 3 round trips and each trip takes 40 ms, what is the total time taken for the connection?
a) 80 ms
b) 100 ms
c) 120 ms
d) 150 ms
Answer:
c) 120 ms
3×40=1203 \times 40 = 1203×40=120 ms
4. If HTTPS encryption adds a 25% overhead to data transfer, how much data is transferred when a 4 MB file is sent?
a) 4 MB
b) 5 MB
c) 6 MB
d) 7 MB
Answer:
b) 5 MB
4+(0.25×4)=54 + (0.25 \times 4) = 54+(0.25×4)=5 MB
5. A website hosted 5000 km away has a network speed of 250,000 km/s. What is the round-trip time (RTT)?
a) 20 ms
b) 30 ms
c) 40 ms
d) 50 ms
Answer:
c) 40 ms
RTT=2×5000250000=40\text{RTT} = \frac{2 \times 5000}{250000} = 40RTT=2500002×5000​=40 ms
6. A browser downloads 12 files, each taking 1 second over HTTP. If HTTPS allows 3 parallel connections, how long will it take?
a) 3 sec
b) 4 sec
c) 5 sec
d) 6 sec
Answer:
b) 4 sec
123=4\frac{12}{3} = 4312​=4 sec
7. An HTTP request takes 500 ms. If switching to HTTPS increases the response time by 20%, what is the new response time?
a) 550 ms
b) 600 ms
c) 650 ms
d) 700 ms
Answer:
b) 600 ms
500+(0.2×500)=600500 + (0.2 \times 500) = 600500+(0.2×500)=600 ms
