answer the following questions about Tor:

Question (a) Give the total amount of advertised bandwidth of relays with the "Guard" flag (but not the "Exit" flag) and relays with the "Exit" flag (but not the "Guard" flag) on 2020-02-01. Which is more? Give one reason to explain this phenomenon.

Question (b) Give the median download rate of a file (in bytes per second) for a 50 KiB file and a 5 MiB file to the op-hk onion server on 2020-02-01. Both files are loaded over 1 round trip. Assuming those two file loads have the same latency and transfer rate, calculate that latency and transfer rate. Then, calculate what percentage of the total load time is due to latency, and what percentage is due to transfer rate. (Those two numbers should add up to 1.)

Question (c) How long would it take to load a 50 KiB file using 2 nodes instead of 3 nodes? For simplicity, assume that all nodes have the same transfer rate and all connections (between nodes, or between nodes and users/servers) have the same latency.

Question (d) How does the use of 4 nodes instead of 3 nodes affect Tor's performance and privacy?
