Mock Exam Questions

Question Number Question Options Correct Answer(s) and Explanation
1 What are the prerequisites for enabling Multi-Cluster support in NDB? a) Registering all clusters to Prism Central b) Configuring network profiles for all clusters c) Ensuring all clusters have the same software version d) Configuring replication settings between clusters Correct Answer: b) Configuring network profiles for all clusters Explanation: The main prerequisite is configuring network profiles for all clusters. Registering clusters to Prism Central is not specifically required for enabling Multi-Cluster support, and ensuring software versions are the same, while recommended, is not a strict requirement.
2 Which information is required to register a new cluster in NDB? a) Cluster name and IP address b) Network configuration (VLAN, DNS) c) Admin credentials of Prism Central d) Available storage containers Correct Answer: a) Cluster name and IP address, b) Network configuration (VLAN, DNS), d) Available storage containers Explanation: Admin credentials for Prism Central (c) are not strictly required when registering a new cluster in NDB.
3 What actions can be performed using the Time Machine feature in NDB? a) Cloning databases b) Snapshot replication c) Database compression d) Data retention management Correct Answer: a) Cloning databases, b) Snapshot replication, d) Data retention management Explanation: Database compression (c) is not a function of the Time Machine; Time Machine is used for cloning, replication, and managing data retention policies.
4 What is the purpose of creating a custom SLA in NDB? a) To define log and snapshot retention periods b) To configure automatic database patching c) To control database access policies d) To set daily, weekly, monthly snapshot retention durations Correct Answer: a) To define log and snapshot retention periods, d) To set daily, weekly, monthly snapshot retention durations Explanation: Custom SLAs are not used for patching (b) or access control (c); they manage log and snapshot retention schedules.
5 When patching a database in NDB, which steps are necessary to ensure minimal disruption? a) Use Maintenance Window settings b) Schedule patching during low-traffic periods c) Manually disconnect all users d) Backup database snapshots before applying patches Correct Answer: a) Use Maintenance Window settings, b) Schedule patching during low-traffic periods, d) Backup database snapshots before applying patches Explanation: Manually disconnecting all users (c) is not typically required as patches are usually applied in a managed way to minimize impact.
6 How do you create a new database profile in NDB? a) Navigate to the Profiles dashboard, click "Create," select Database Profile b) Configure compute and network settings in the profile creation wizard c) Assign storage and compute resources in Prism Central d) Publish the profile after creation Correct Answer: a) Navigate to the Profiles dashboard, click "Create," select Database Profile, b) Configure compute and network settings in the profile creation wizard, d) Publish the profile after creation Explanation: c) Assigning resources in Prism Central is not part of creating a database profile in NDB; it is done in NDB directly.
7 What roles are necessary for administering databases in NDB? a) NDB Manager b) DB Administrator c) NDB Infrastructure Admin d) NDB Auditor Correct Answer: a) NDB Manager, b) DB Administrator Explanation: NDB Manager and DB Administrator roles are needed for administering databases. NDB Infrastructure Admin is not specifically required for database administration, and NDB Auditor is typically for auditing purposes only.
8 Which components can be managed from the NDB Alerts dashboard? a) Alerts policies b) Diagnostic bundles c) Maintenance windows d) Alert retention settings Correct Answer: a) Alerts policies, d) Alert retention settings Explanation: Diagnostic bundles (b) are generated from the Diagnostics menu, and Maintenance windows (c) are managed separately from alerts.
9 How do you clone a database using a replicated snapshot in NDB? a) Select snapshot, click "Clone," configure network and compute settings, initiate clone b) Replicate snapshot to target cluster, select snapshot, choose "Clone," provide necessary settings c) Select database profile, assign resources, initiate snapshot d) Configure a clone job in Prism Element Correct Answer: a) Select snapshot, click "Clone," configure network and compute settings, initiate clone, b) Replicate snapshot to target cluster, select snapshot, choose "Clone," provide necessary settings Explanation: c) and d) are incorrect because snapshots must be handled within NDB, not through profiles or directly in Prism Element.
10 What must be considered when creating network profiles for a new cluster in NDB? a) VLAN and IP address ranges b) DNS settings c) Cluster time zone d) Subnet mask and gateway Correct Answer: a) VLAN and IP address ranges, b) DNS settings, d) Subnet mask and gateway Explanation: Time zone (c) is not directly related to network profiles; it's more relevant to database or server settings.
11 When restoring a database from a snapshot in NDB, what steps must be followed? a) Select snapshot, choose restore point, confirm settings, execute restore b) Delete existing database, replicate snapshot, restore database c) Select snapshot, configure clone settings, restore to the original server d) Ensure all dependent services are stopped before restore Correct Answer: a) Select snapshot, choose restore point, confirm settings, execute restore Explanation: b) is incorrect because deleting a database is not typically required, c) confuses cloning with restoring, and d) is not always required unless there are specific service dependencies.
12 [Hard] Which actions should be taken to replicate a software profile to a new cluster in NDB? a) Select the profile, choose the target cluster, initiate replication, monitor operation b) Copy profile to a shared location, import to target cluster, configure settings c) Initiate replication directly from Prism Central d) Publish the profile, then replicate to new cluster Correct Answer: a) Select the profile, choose the target cluster, initiate replication, monitor operation Explanation: b) and c) are incorrect as these do not align with NDB’s replication mechanism. d) seems plausible but is misleading because "publish" is not needed before replication to a new cluster.
13 [Hard] What is required to provision a high-availability (HA) database in NDB? a) Use HA software profile b) Configure multiple database server VMs across clusters c) Ensure all clusters are on the same subnet d) Apply an HA-compliant SLA Correct Answer: a) Use HA software profile, b) Configure multiple database server VMs across clusters Explanation: c) is not a requirement; clusters can be in different subnets. d) is incorrect because SLA does not directly impact HA configuration.
14 [Hard] How do you configure alerts to be automatically resolved in NDB? a) Set alert policy to "Auto-Resolve" b) Disable alert retention for auto-resolved alerts c) Enable automatic acknowledgment in Alerts dashboard d) Configure the alert type to resolve upon the next successful operation Correct Answer: d) Configure the alert type to resolve upon the next successful operation Explanation: a), b), and c) seem correct but NDB does not have explicit "Auto-Resolve" or "automatic acknowledgment" settings in this context; alerts resolve based on conditions.
15 [Hard] What must be done before cloning a database to another cluster using Time Machine? a) Ensure Time Machine is enabled for both clusters b) Verify storage availability on the target cluster c) Confirm network profiles are correctly configured d) Snapshot the database on the source cluster first Correct Answer: a) Ensure Time

Machine is enabled for both clusters, b) Verify storage availability on the target cluster, c) Confirm network profiles are correctly configured Explanation: d) seems correct but is misleading; snapshots should already exist as part of the Time Machine setup before cloning. |

Additional Explanation for the Hard Questions:

  1. Question 12: Replicating Software Profiles:

    • Correct Answer: a) Select the profile, choose the target cluster, initiate replication, monitor operation
    • Why It's Correct: This option follows the correct NDB process for replicating a software profile.
    • Why Others Are Wrong:
      • b) Suggests an unnecessary step of copying to a shared location.
      • c) Incorrect because replication does not occur via Prism Central.
      • d) "Publishing" is not needed for replication, which could mislead you.

  2. Question 13: Provisioning HA Database:

    • Correct Answer: a) Use HA software profile, b) Configure multiple database server VMs across clusters
    • Why It's Correct: Both are necessary for HA provisioning.
    • Why Others Are Wrong:
      • c) Assumes a subnet requirement that is not needed.
      • d) Suggests an SLA configuration, which does not directly affect HA.

  3. Question 14: Configuring Alerts:

    • Correct Answer: d) Configure the alert type to resolve upon the next successful operation
    • Why It's Correct: Alerts in NDB are managed this way.
    • Why Others Are Wrong:
      • a) and c) talk about settings that do not exist in the context.
      • b) Disabling retention does not achieve auto-resolution.

  4. Question 15: Cloning a Database to Another Cluster:

    • Correct Answer: a) Ensure Time Machine is enabled for both clusters, b) Verify storage availability on the target cluster, c) Confirm network profiles are correctly configured
    • Why It's Correct: All these are prerequisites for cloning.
    • Why Others Are Wrong:
      • d) Misleading because the snapshot should already exist in Time Machine.
