Q1Domain Verified
In the context of MySQL replication, what is the primary mechanism that allows a replica server to process transactions applied by the source server, ensuring data consistency across the cluster?
Binary Log (binlog) file rotation and archival
The SQL thread's ability to parse and execute events from the relay log
Replication filtering rules applied at the replica level
The I/O thread's capability to fetch and buffer events from the source's binary log
Q2Domain Verified
When configuring asynchronous replication in MySQL, which of the following replication formats offers the highest level of data integrity and is generally preferred for critical production environments, despite potentially higher overhead?
Row-Based Replication (RBR)
Mixed-Based Replication (MBR)
Statement-Based Replication (SBR)
Transaction-Based Replication (TBR)
Q3Domain Verified
Consider a scenario where a MySQL source server experiences an unexpected crash. In a synchronously replicated setup using Group Replication with multiple replicas, what is the expected behavior of the remaining active replicas to maintain quorum and ensure continued availability?
The remaining replicas will enter a read-only state until the failed primary is restored or replaced.
The remaining replicas will attempt to reconnect to the failed primary and wait for its recovery.
The remaining replicas will automatically elect a new primary and continue serving read/write traffic.
The remaining replicas will initiate a full data resynchronization from scratch.
