Nutanix Certified Professional - Database Automation (NCP-DB) 6.5: Ready-to-Pass Handout

1. Core Understanding of Nutanix Database Service (NDB)

NDB Overview: NDB (formerly Nutanix Era) is a platform that automates database management tasks like provisioning, cloning, patching, and data protection. It runs on Nutanix infrastructure, integrating with Nutanix Prism (management interface) and AOS (Acropolis Operating System).
Key Features:
- One-Click Provisioning: Automates the creation of new database instances.
- One-Click Patching: Streamlines the process of applying updates to databases.
- Time Machine: Manages snapshots for data protection and point-in-time recovery.
- High Availability (HA): Ensures databases remain operational even during hardware or software failures.

2. Essential Terminology

NDB Software Compatibility: Make sure your versions of NDB, AOS, Prism, and database engines (e.g., Oracle, SQL Server) are compatible.
Time Machine SLAs: Define how often snapshots are taken and how long they are retained.
Data Access Management (DAM): Controls access to database copies, ensuring data security.
Provisioning Profiles: Templates that allocate CPU, memory, and storage when deploying databases.
Copy Data Management (CDM): Manages data copies efficiently to reduce redundancy and save storage.

3. Key Exam Objectives and How to Master Them

Provisioning Databases (One-Click Provisioning)

What You Need to Know:
- Purpose: Automates the setup of new databases, saving time and reducing errors.
- Real-World Use: Quickly deploy databases with consistent settings using predefined templates.
- Example: “One-Click” means exactly that—choose your database type, select a template, and provision.

Patching Databases (One-Click Patching)

What You Need to Know:
- Purpose: Keep your databases secure by applying patches with minimal downtime.
- Real-World Use: Automate patching to ensure all databases are up-to-date without manual intervention.
- Example: Imagine applying updates to all your databases with a single click, ensuring they are all protected against vulnerabilities.

Cloning Databases

What You Need to Know:
- Purpose: Create exact copies of databases for testing or backup purposes.
- Real-World Use: Use clones to test new features or backups without affecting the original database.
- Example: Think of cloning as making a copy of your database in seconds, ready for experimentation or safety.

Data Protection

What You Need to Know:
- Purpose: Safeguard your data using snapshots and backups to prevent data loss.
- Real-World Use: Implement SLAs that dictate how often your data is backed up and for how long it’s retained.
- Example: Protect your critical data by ensuring you can recover from any point in time using Time Machine SLAs.

4. Step-by-Step Overview

Deploying an NDB Instance

1. Download and Import:
- Get the NDB software package and import it into your virtual environment (AHV or ESXi).
2. Create Instance:
- Set up the NDB instance, configure the VM, and assign resources.
3. Assign Static IP:

- Key Tip: Focus on consistency—use the same profile for similar workloads to ensure uniform performance.
Scenario 2: Securing Data with SSL
- What to Do: Install SSL certificates to encrypt all data transmitted between clients and the NDB server.
- Key Tip: Always verify that your SSL certificates are correctly installed by testing secure connections.
Scenario 3: Implementing High Availability
- What to Do: Configure NDB to automatically failover to a backup node in case the primary node fails.
- Key Tip: Regularly test your HA setup by simulating failures and ensuring your databases stay online.

6. Quick Q&A for Exam Preparation

Q1: What does Time Machine SLA manage?

A: It manages snapshot schedules, retention periods, and replication for data protection.

Q2: How does One-Click Patching benefit your database management?

A: It automates the patching process, minimizing downtime and keeping databases secure without manual intervention.

Q3: Why is it important to configure a static IP for NDB?

A: A static IP ensures consistent and stable network communication, which is critical for database operations.

Q4: What is the purpose of Provisioning Profiles?

A: They allocate the necessary resources (CPU, memory, storage) for new database deployments, ensuring optimal performance.

7. Final Exam Tips
