Which of the following best distinguishes read repair from anti-entropy repair in Cassandra?
Options
A.Read repair is a manual process triggered by the administrator, while anti-entropy repair happens automatically during each read operation.
B.Read repair synchronizes only data actively read by clients, while anti-entropy repair performs a full data comparison between replicas to fix inconsistencies.
C.Read repair uses Merkle trees for comparison, while anti-entropy repair relies on read-time timestamps.
D.Read repair is used only in eventual consistency mode, while anti-entropy repair is used in strong consistency mode.

Step-by-Step Analysis
Question restatement: Which of the following best distinguishes read repair from anti-entropy repair in Cassandra?
Option 1: Read repair is a manual process triggered by the administrator, while anti-entropy repair happens automatically during each read operation.
-Analysis: This is inaccurate. Read repair is not a manual process; it is an automatic process that can occur during reads at read time, but anti-entropy repair is not tied to every rea......Login to view full explanationLog in for full answers

Distributed Databases Scenario: you are hired as a consultant, specialising in distributed databases! For each of the following scenarios, explain which distribution strategy is best to overcome the problem. 1: For a Sharepoint site, you have users located in both Melbourne and Singapore. Both need full access to all of the data at maximum speed. The data, however, gets updated very rarely (say once every 3 months). 2: For the Salesforce Customer Relationship Management system, you have users located in both Asia and Europe. However, generally, SOME rows in the tables are used more regularly in Asia (e.g., salespeople in China look up more records for customers in China), and some are used more regularly in Europe (likewise for France). Not many analytical queries involving data from other regions are required, and in general, updates are happening to tables very rapidly. 3: For the Australian Football League information website, its users are based primarily in the Australian region (nearby the DB in Sydney), and in general the performance of the DB is currently acceptable and data is being backed up already offsite safely. If the service goes down for hours to days, it’s not ideal but not mission critical to the business. 4: For the National Gallery of Victoria (NGV) database, its users are mainly people who love art in the Australian region. Therefore, speed is essential for these users, to access basic information about NGV's art collection and a preview image of less than 1MB. However, the NGV also stores very high-resolution image data (up to 1GB) in Silicon Valley (USA) due to cheaper cost of storage there; these large image files are accessed mostly by arts scholars, at most twice a month.
Distributed Databases Determine whether the following statements are true or false: 1: Non-distributed databases can always provide both availability and consistency 2: Distributed databases can provide both availability and consistency, as long as no network partition exists 3: Distributing a database is only necessary/useful when we can no longer scale the database vertically (i.e. we cannot buy a better local server) 4: Transactions are necessary in distributed databases but not in centralized databases 5: If vertical or horizontal partitioning is used in a distributed database, that partitioned data cannot be replicated if the database needs to remain consistent.
In a federated database,
Cassandra adopts the peer-to-peer replication model.
