In a circular Distributed Hash Table (DHT) with no shortcuts, 8 peers participate. These peers have the following interior identifiers. Assume that the closest ID algorithm is used in assigning records with hash values to a peer for a database of 8192 records.
| Peer # | Identifier |
| 1 | 88 |
| 2 | 440 |
| 3 | 1325 |
| 4 | 2150 |
| 5 | 4802 |
| 6 | 5432 |
| 7 | 6750 |
| 8 | 7320 |
- in which peer a record with hash number 4012 is stored? How about hash number 8191?
- If a user places a query on peer #4, asking for a record of hash number 441, what is the sequence of peers this query and its response would have to go through for the user to receive its response?
