Troubleshoot and optimize (25–30%)

  • Optimize queries

·         Understand statistics; read query plans; plan guides; DMVs; hints; statistics IO; dynamic vs. parameterized queries; describe the different join types (HASH, MERGE, LOOP) and describe the scenarios they would be used in

  • Manage transactions

·         Mark a transaction; understand begin tran, commit, and rollback; implicit vs explicit transactions; isolation levels; scope and type of locks; trancount
