質問 # 40
An administrator is interested in using profiles to simplify the database provisioning process. The profile needs to include information related to the SQL service startup account, and the NDB worker service account.
Which profile would help the administrator accomplish this task?
- A. Database Parameter
- B. Network
- C. Windows Domain
- D. Software
正解：C
解説：
The correct answer is A because the Windows Domain profile is the profile that includes information related to the SQL service startup account and the NDB worker service account. A Windows Domain profile is a collection of settings that define how NDB manages Windows-based database servers and databases. It contains the following information:
The domain name and credentials to join the database server VMs to the domain The SQL service startup account and password to run the SQL Server service on the database server VMs The NDB worker service account and password to run the NDB Database Agent service on the database server VMs The SQL Server authentication mode to use for the databases By using a Windows Domain profile, the administrator can simplify the database provisioning process by applying the same settings to multiple database server VMs and databases, without having to manually enter them each time. The other options are not correct because they describe different types of profiles that do not include information related to the SQL service startup account and the NDB worker service account. Option B is not correct because the Network profile is a profile that defines the network settings for the database server VMs, such as the IP address, subnet mask, gateway, DNS, and VLAN. Option C is not correct because the Database Parameter profile is a profile that defines the database parameters for the databases, such as the memory, CPU, storage, and performance settings. Option D is not correct because the Software profile is a profile that defines the software settings for the database server VMs and databases, such as the database engine version, edition, and features.

Which statement best describes what happens when a 3rd-party backup tool is chosen to manage log backups for Microsoft SQL in NDB?
- A. Third-party backups vendors can continue to backup the archived logs from the database log destination. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get backed up
- B. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will not be supported, but snapshot-based recovery of the databases is supported.
- C. Third-party backups vendors can continue to backup the binary logs from the binary log location. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get purged.
- D. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will be supported, but snapshot-based recovery of the databases is not supported.
正解：A

質問 # 44
An administrator has configured NDB HA across multiple Nutanix clusters.
Which failure scenario will require manual interaction for the recovery?
- A. More than one API Server VM is down.
- B. More than one HA proxy VM is down.
- C. NDB Server process is down.
- D. One repository VM is down.
正解：A
解説：
NDB HA is a feature that provides high availability and resilience for the NDB service and its components. NDB HA creates a cluster of API server VMs, repository VMs, and HAProxy VMs across multiple Nutanix clusters. Each component has a leader and a set of followers that are synchronized and can take over the leader role in case of a failure. NDB HA also monitors the health and status of the NDB components and performs automatic failover and recovery actions when possible. However, some failure scenarios may require manual intervention from the administrator to restore the NDB service. One such scenario is when more than one API server VM is down. The API server VMs are responsible for handling the requests from the NDB UI and CLI, as well as communicating with the repository VMs and the HAProxy VMs. If more than one API server VM is down, the NDB service may become unavailable or unstable, and the administrator will need to manually restart or redeploy the affected API server VMs.
The other options do not require manual interaction for the recovery, as NDB HA can handle them automatically. If one repository VM is down, NDB HA will fail over to another repository VM that has the latest data. If more than one HAProxy VM is down, NDB HA will route the traffic to the remaining HAProxy VMs. If the NDB server process is down, NDB HA will restart the process or fail over to another API server VM.
