Here you have the best Teradata TDVCL1 practice exam questions
Which type of index defined the data distribution?
Non-unique Primary Index (NUPI) defines the data distribution. In databases, the primary index, whether unique or non-unique, is responsible for determining how data is distributed across the storage system.
Why would VantageCloud Lake be chosen rather than VantageCloud Enterprise for a workload?
VantageCloud Lake is chosen for a workload due to its ability to use Compute Clusters for intelligent scaling. This ability allows the system to dynamically scale resources based on workload demands, providing flexibility and efficiency in managing varying workloads. VantageCloud Enterprise may not offer this specific capability, making VantageCloud Lake a more suitable choice for tasks requiring such intelligent scaling capabilities.
Which component of Vantage should be used for tactical queries?
Compute Cluster in Teradata Vantage is designed to handle tactical queries efficiently. These can process queries quickly and are optimized for such operations compared to the other components listed.
Which VantageCloud Lake feature provides additional BYNET-connected nodes within the Primary Cluster?
The feature that provides additional BYNET-connected nodes within the Primary Cluster is Compute Worker. Compute Clusters are typically external to the Primary Cluster and provide additional computing power without being directly connected via BYNET. Hence, the correct answer is Compute Worker.
Which type of locking blocks only exclusive requests?
Read locks block only exclusive requests, allowing shared (read) operations to continue without interference. This means multiple read operations can take place simultaneously while preventing any write operations from occurring, ensuring data consistency.
