Options:
A. sys.dm_pdw_nodes_tran_locks
B. sys.dm_exec_compute_node_errors
C. sys.dm_exec_requests
D. sys.dm_cdc_errors
E. sys.dm_pdw_nodes_os_wait_stats
F. sys.dm_tran_locks
Answer: A, E
Explanation: xperiences performance issues that are likely due to out-of-date statistics and frequent blocking queries. A: Use sys.dm_pdw_nodes_tran_locks instead of sys.dm_tran_locks from Azure Synapse Analytics (SQL Data Warehouse) or Parallel Data Warehouse. E: Example: The following query will show blocking information. SELECT Microsoft DP-300

t1.resource_type, t1.resource_database_id, t1.resource_associated_entity_id, t1.request_mode, t1.request_session_id, t2.blocking_session_id FROM sys.dm_tran_locks as t1 INNER JOIN sys.dm_os_waiting_tasks as t2 ON t1.lock_owner_address = t2.resource_address; Note: Depending on the system you’re working with you can access these wait statistics from one of three locations: sys.dm_os_wait_stats: for SQL Server sys.dm_db_wait_stats: for Azure SQL Database sys.dm_pdw_nodes_os_wait_stats: for Azure SQL Data Warehouse Incorrect Answers: F: sys.dm_tran_locks returns information about currently active lock manager resources in SQL Server 2019 (15.x). Each row represents a currently active request to the lock manager for a lock that has been granted or is waiting to be granted. Instead use sys.dm_pdw_nodes_tran_locks.

Litware identifies business requirements include: meet an SLA of 99.99% availability for all Azure deployments. Box 1: Cloud witness If you have a Failover Cluster deployment, where all nodes can reach the internet (by extension of Azure), it is recommended that you configure a Cloud Witness as your quorum witness resource. Box 2: Azure Basic Load Balancer Microsoft guarantees that a Load Balanced Endpoint using Azure Standard Load Balancer, serving two or more Healthy Virtual Machine Instances, will be available 99.99% of the time. Note: There are two main options for setting up your listener: external (public) or internal. The external (public) listener uses an internet facing load balancer and is associated with a public Virtual IP (VIP) that is accessible over the internet. An internal listener uses an internal load balancer and only supports clients within the same Virtual Network.

https://www.certification-questions.com
Options:
A. Answer: A
Explanation: cenario: The 30 new databases must scale automatically. Once all requirements are met, minimize costs whenever possible. You can configure resources for the pool based either on the DTU-based purchasing model or the vCore-based purchasing model. In short, for simplicity, the DTU model has an advantage. Plus, if you’re just getting started with Azure SQL Database, the DTU model offers more options at the lower end of performance, so you can get started at a lower price point than with vCore.

Box 2: An Azure SQL database elastic pool Azure SQL Database elastic pools are a simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands. The databases in an elastic pool are on a single server and share a set number of resources at a set price. Elastic pools in Azure SQL Database enable SaaS developers to optimize the price performance for a group of databases within a prescribed budget while delivering performance elasticity for each database.
