Spark Workspace Settings: 10 practice questions

Question 1 of 10

A workspace admin turns on Set maximum job lifetime with a value of 2 hours. Which of these runs can still be active after 3 hours?

1. AA Livy interactive session in high concurrency mode
2. BA scheduled notebook run that a pipeline orchestrates
3. CA Spark job definition run that was submitted on a schedule
4. DA lakehouse table maintenance operation that runs optimize

Question 2 of 10

A workspace on an F64 capacity runs small notebooks on the starter pool. A new job needs nodes with 128 GB of memory. It should use 2 nodes on quiet days, grow to 12 on busy days, and release nodes when the work is done. Which configuration fits?

1. AThe starter pool with its maximum raised to 12 nodes
2. BA custom pool of Large nodes with autoscale from 2 to 12
3. CA custom pool of Large nodes with autoscale off and 12 nodes
4. DAn environment on the starter pool with 128 GB of executor memory

Question 3 of 10

Users report that the notebook menu no longer offers the option to start a new high concurrency session. Which workspace Spark setting was changed?

1. AThe default environment option was disabled in the Environment tab
2. BReserve maximum cores for active Spark jobs was enabled
3. CThe For notebooks setting under High concurrency was disabled
4. DCustomize compute configurations for items was turned off

Question 4 of 10

A workspace admin opens Spark settings to create a custom pool and cannot create one. Which setting must a capacity admin enable for the capacity?

1. ACustomize compute configurations for items
2. BCustomized workspace pools
3. CReserve maximum cores for active Spark jobs
4. DDynamically allocate executors

Question 5 of 10

A contributor opens an environment to raise the executor memory for one notebook, but the Compute section is disabled. What should the workspace admin change?

1. ATurn on Reserve maximum cores for active Spark jobs
2. BTurn on Customize compute configurations for items
3. CCreate a custom pool and make it the workspace default pool
4. DSet that environment as the workspace default environment

Question 6 of 10

An F32 capacity can use up to 192 Spark VCores with burst. A workspace admin enables Reserve maximum cores for active Spark jobs, and every job uses a pool with a maximum of 64 Spark VCores. How many of these jobs can run at the same time?

1. A8 jobs
2. B3 jobs
3. C24 jobs
4. D32 jobs

Question 7 of 10

All notebooks in a workspace must start with the same Spark runtime and the same custom library packages. Contributors must not be able to change driver or executor sizes for their own items. Which setup meets both needs?

1. ASelect a default Environment and keep item compute customization off
2. BCreate a custom pool as the default pool and select a runtime version
3. CDisable the default Environment and select a runtime version
4. DSelect a default Environment and turn item compute customization on

Question 8 of 10

On a busy capacity, the jobs of one workspace start quickly but then stay at their minimum nodes for hours. The team wants each job to be sure of its full compute from the moment it starts, and accepts that fewer jobs will run at once. The autoscale ranges of the pools must stay as they are. What should the admin do?

1. AEnable Reserve maximum cores for active Spark jobs
2. BRaise the maximum node count of the workspace default pool
3. CSet a maximum job lifetime to cancel long-running jobs
4. DDisable autoscale and set a fixed node count on the default pool

Question 9 of 10

Customize compute configurations for items is on in a workspace that has only the starter pool. A contributor's notebook needs Large nodes. What is needed before the notebook can run on Large nodes?

1. AThe contributor must create a custom pool in Spark settings, now that the toggle is on
2. BA workspace admin must create a custom pool of Large nodes in Spark settings
3. CThe contributor must create a custom pool in the Compute section of an environment
4. DThe contributor must set the starter pool to Large nodes in an environment

Question 10 of 10

A new workspace uses its starter pool, and nobody has edited the pool. What is the state of Autoscale and of Dynamically allocate executors?

1. ABoth options are disabled by default
2. BOnly Dynamically allocate executors is enabled
3. CBoth options are enabled by default
4. DOnly Autoscale is enabled
