質問 # 74
Where would an administrator find the total space being used by all Era clones for a specific database?
正解：C
解説：
Nutanix Era leverages the Nutanix time-efficient snapshots to create the clones. These database clones are highly space-efficient, consuming near-zero bytes by having only the further writes constituting to its size. Therefore, an administrator would find the total space being used by all Era clones for a specific database under the Cloning widget on the Databases > Clones database summary page. The other options do not specifically provide information about the total space used by all Era clones for a specific database. Therefore, the correct answer is A. Under the Cloning widget on the Databases > Clones database summary page.
質問 # 75
An administrator needs to add multiple databases to an existing PostgreSQL instance. How should the administrator satisfy this requirement?
正解：D
解説：
To add multiple databases to an existing PostgreSQL instance managed by NDB, the administrator should use the NDB graphical user interface (GUI). The GUI provides a user- friendly way to modify the parameter profile associated with the PostgreSQL instance, allowing the addition of new databases by adjusting settings such as database names, sizes, or configurations. This process typically involves navigating to the "Databases" or "Instances" section, selecting the PostgreSQL instance, and editing the parameter profile to include additional databases.
質問 # 76
An administrator has noticed that the automatic snapshot and log catch-up (automatic and manual) activities for a Time Machine are halted and manual snapshots cannot be created.
What status is this Time Machine in?
正解：A
解説：
In NDB, a Time Machine manages snapshots and log catch-up operations for database protection and recovery. The scenario describes a Time Machine where automatic snapshot and log catch-up activities (both automatic and manual) are halted, and manual snapshots cannot be created. This indicates the Time Machine is in a PAUSED state.
In NDB, the Time Machine states are:
FROZEN: A temporary state during specific operations (e.g., cloning), but it doesn't halt all activities permanently.
OFFLINE: Indicates the Time Machine is unavailable or not operational, often due to connectivity or configuration issues, but this typically prevents access rather than just halting operations.
PAUSED: Explicitly stops all scheduled and manual snapshot/log activities, often manually triggered by an administrator or due to an error condition (e.g., resource constraints). Operations resume when unpaused.
READY: The normal operational state where snapshots and log catch-ups occur as scheduled.
Given the inability to create manual snapshots alongside halted automatic operations, PAUSED is the most fitting status, as it reflects an intentional or enforced suspension of activities.
質問 # 77
What is the terminology used for registering an existing database with Era?
正解：D
解説：
In the context of Nutanix Era, the term "Brownfield Database" is used to refer to an existing database that is registered with Era. This process allows Era to bring Database as a Service (DBaaS) capabilities to your existing database. It's important to note that before you register a database with Era, certain prerequisites must be met.
質問 # 78
A request is received to refresh a database clone from a new manual snapshot. When the administrator attempts to create the new snapshot from the Time Machine, it is in a Frozen state.
What causes a Time Machine to enter the Frozen state and what are the administrator's options to complete the request?
正解：B
解説：
A Time Machine is a core construct of the copy data management service in NDB that captures and manages the data of a database to deliver a recovery point objective (RPO) SLA. A Time Machine can enter a Frozen state for various reasons, such as database de-registration, snapshot or log catchup failures, or manual intervention. When a Time Machine is in a Frozen state, it stops taking new snapshots and log backups, and cannot perform any clone, refresh, or restore operations. To resume the normal operation of a Time Machine, it must be thawed by resolving the root cause of the freeze. One of the common causes of a Time Machine freeze is when the database is de-registered from NDB without removing the Time Machine. This can happen when the administrator wants to move the database to a different NDB instance or cluster, or when the database is accidentally de- registered. In this case, the Time Machine becomes orphaned and frozen, and cannot be used for any operations. To complete the request to refresh a database clone from a new manual snapshot, the administrator must first re-register the database in NDB using the same database name and ID as before. This will automatically thaw the Time Machine and resume its operation. The administrator can then create a new manual snapshot from the Time Machine and use it to refresh the database clone. The other options are not correct, as they either require unnecessary steps or do not address the root cause of the freeze.
