Question #16
What is causing this issue?
- A . The VLAN is DHCP
- B . The VLAN is static
- C . The VLAN is stretched
- D . The VLAN is IPAM
Correct Answer: C
C
Explanation:
The correct answer is C because a stretched VLAN is a VLAN that spans across multiple Nutanix clusters, which may cause network conflicts or latency issues when starting the database server. Option A is incorrect because a DHCP VLAN is a VLAN that uses dynamic IP address allocation, which does not affect the database server startup. Option B is incorrect because a static VLAN is a VLAN that uses fixed IP address allocation, which also does not affect the database server startup. Option D is incorrect because IPAM is not a type of VLAN, but a feature of NDB that allows managing IP addresses for database servers and databases.

Question #18
An administrator needs to migrate a large 1/0-intensive database that doesn’t support multi-disk layout.
How should the storage be provisioned with Era to support the database while optimizing performance?
- A . Volume Group
- B . Volume Group with Load Balancing
- C . Storage Spaces
- D . vDisk based provisioning
Correct Answer: A
A
Explanation:
In Nutanix Era, a Volume Group is the recommended storage provisioning method for a large I/O-intensive database that doesn’t support a multi-disk layout1. A Volume Group in Nutanix Era is a collection of disks that can be managed as a single entity, providing a way to aggregate the storage capacity of multiple disks into a larger storage unit1. This allows for better performance optimization as it enables the database to leverage the combined I/O capabilities of all the disks in the group1. It’s important to note that while other options like Load Balancing, Storage Spaces, and vDisk based provisioning can also be used in certain scenarios, a Volume Group is specifically designed for situations where a single, high-performance storage unit is required1.

Question #19
Where should an administrator perform an upgrade within the Era management interface?
- A . Operations > Current Recent
- B . Profiles Software
- C . Alerts
- D . Administration > Maintenance
Correct Answer: D
D
Explanation:
In the Nutanix Era management interface, an administrator should perform an upgrade under the Administration > Maintenance section1. As part of the upgrade process, the Era server is upgraded first, followed by all the Era cluster agents and database server agents in parallel1. The Dashboard displays the current version and an option to upgrade the Era server to a latest version when a new version is available for upgrade1. This ensures that the Nutanix Era environment is always up-to-date with the latest features and security updates1.

Question #20
A legal team wants to audit a quarter end (July 31st) banking transaction event and asks the administrator to create a SQL database from the timeframe.
What action should the administrator perform within Era?
- A . Provision a database and attach the July 31st backup from Time Machine.
- B . Restore a backup from July 31st, Recover the database to bring the database up.
- C . Provision a database, restore the backup from Ju)’ 31st, and Recover the database to bring the database up.
- D . Create a clone from July 31st snapshot in Time Machine.
Correct Answer: D
D
Explanation:
Nutanix Era enables you to clone your source databases (running on Nutanix clusters) and refresh the database clones by using snapshots or transaction logs1. Era uses storage-efficient and time-efficient Nutanix snapshots, thus lowering the cost of managing multiple copies of your databases1. In this case, the administrator should create a clone from the July 31st snapshot in Time Machine to provide the legal team with the specific banking transaction event data they need for their audit1.
