Pоtpоurri The cоntext for this question is the sаme аs the previous question. You аre working on a large financial data system. This system contains a complete view of trades ingested from various exchanges. The primary feature is a read heavy, highly detailed dashboard that shows all open positions, and offers various search filters for analyzing relevant trades. The system’s data is updated in batches via intraday SFTP files delivered every 5-30 minutes, depending on the exchange. Assumptions and Considerations: Each dashboard request may need to consult the full corpus of data A partial answer may be considered unsafe The system uses full replication on each node b) [2 points] Suppose instead of waiting for the intraday files to see new trades in batches, the system starts to receive updates about all trades in real time. The dashboard should still display all the same information but now have access to real time trade data. In 1-2 bullets, explain why full replication becomes a bottleneck for this shift in workload. Be specific about what must happen on each write operation.
Pоtpоurri [2 pоints] Through the speciаl nаture of the Login process interаction between Virtue and Vice, an ephemeral identity and a handshake key to use during that Login session is given by Vice to the Virtue workstation for a legitimate user of AFS. Given this, why can’t Virtue simply use this ephemeral identity and encrypting all the subsequent file system calls that the user makes to the file server using the handshake key? (Multiple choice -- choose 1 by specifying its number) i) Toward off replay attacks ii) Since the handshake key is for one-time use by Virtue iii) To reduce over-exposure of the handshake key within the login session iv) Since the handshake key is valid only for a limited time v) Since the handshake key is valid only for a limited number of calls to the file server

Your answer should include 3 bullet points that clearly specify what replication strategy you will use, how data is distributed, and how fault tolerance is preserved.
