What is a common pitfall when configuring a multi-data center Cassandra cluster with a low replication factor? Reduced read and write latencies. Increased storage costs. Higher risk of data loss during node failures. Increased network traffic between data centers. None Show Hint A low replication factor reduces redundancy, increasing the risk of data loss if nodes fail, especially in a multi-data center setup where cross-data center replication may not compensate for local failures. 2. How does the 'local_quorum' consistency level affect write operations in a multi-data center Cassandra cluster? It ensures that the write is acknowledged by a quorum of nodes in the local data center only. It guarantees immediate consistency across all data centers. It increases the write latency due to cross-data center communication. It requires a quorum of nodes in all data centers to acknowledge the write. None Show Hint The 'local_quorum' consistency level ensures that write operations are acknowledged by a quorum of nodes in the local data center, reducing latency by avoiding cross-data center communication.
