Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A distributed banking system updates account balances on two separate servers simultaneously. Describe the potential issues that can arise from unsynchronized clocks and suggest a synchronization strategy to mitigate this risk.

💡 Hint: Consider possible consequences if timestamps overlap.

Challenge 2 Hard

Design a simple protocol to handle clock skew using external synchronization. Describe how nodes would adjust their clocks upon receiving time data from a time server.

💡 Hint: Think about the implications of quick versus gradual adjustments.
