Q1Domain Verified
When performing a cross-cluster snapshot restore to a different Elasticsearch cluster with a different shard count for the target index, what is the primary consideration to ensure data integrity and performance during the restore process?
Elasticsearch automatically rebalances shards during the restore, so no explicit configuration is neede
The target index's mapping must be explicitly defined and compatible with the snapshot's original mapping.
The snapshot repository must be accessible from both the source and target clusters simultaneously.
D) The target cluster's disk space must be at least double the size of the snapshot to accommodate rebalancing.
Q2Domain Verified
In a disaster recovery scenario, what is the most significant advantage of using Elasticsearch's snapshot lifecycle management (SLM) feature compared to manual snapshot creation and retention policies?
SLM offers real-time, continuous backup capabilities, minimizing data loss to near-zero.
SLM provides built-in encryption for all snapshots, ensuring compliance with stringent security regulations without additional configuration.
SLM automatically optimizes snapshot storage by deduplicating data across multiple snapshots.
SLM automates the entire snapshot process, including repository creation, snapshot scheduling, and retention, reducing operational overhead and human error.
Q3Domain Verified
Consider a scenario where a critical index has been accidentally deleted from an Elasticsearch cluster. You have a recent snapshot of this index stored in a remote repository. What is the most crucial step to take *before* initiating the restore process to minimize the risk of data loss during the operation?
Increase the cluster's shard allocation awareness settings to prioritize the restore operation.
Ensure the target index does not exist on the cluster, or rename the existing index to avoid conflicts.
Verify the integrity of the snapshot by performing a dry run restore to a temporary index.
Temporarily disable shard allocation and routing on the cluster to prevent any background activity.
