Q1Domain Verified
In the context of DigitalOcean Managed Databases, which of the following best describes the primary benefit of utilizing read replicas for a PostgreSQL cluster?
Automatic failover capabilities with zero downtime in case of primary node failure.
Reduced latency for read-heavy workloads by offloading queries to dedicated replica instances.
Improved write performance by distributing write operations across replica nodes.
Enhanced data durability through synchronous replication to multiple nodes.
Q2Domain Verified
When configuring a DigitalOcean Managed Database for Redis, what is the most significant consideration regarding memory management and eviction policies for a scenario involving a constantly growing cache that must prioritize recent data?
Setting a large `maxmemory` limit to accommodate all data indefinitely.
Implementing a strict `maxmemory-policy` of `noeviction` to prevent any data loss.
Regularly performing manual backups and then clearing the cache to reset memory usage.
Utilizing the `allkeys-lru` eviction policy to remove the least recently used keys.
Q3Domain Verified
A developer is experiencing intermittent connection timeouts when interacting with their DigitalOcean Managed MySQL database. They have confirmed their application server's network connectivity is stable. What is the most likely architectural or configuration issue within the Managed Database service itself that could cause this?
The database cluster is configured with insufficient IOPS provisioning for the workloa
D) The managed database is not configured with SSL/TLS encryption, leading to packet loss.
The primary node is experiencing excessive CPU utilization due to poorly optimized queries.
The read replica is configured with a significantly higher version of MySQL than the primary.
