VM sizes and series (B, D, E, F) in Azure - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main purpose of the B-series VMs in Azure?

B-series VMs are designed for workloads that do not need continuous full CPU performance but can burst when needed. They save cost by accumulating credits during low usage and using them during bursts.

Which Azure VM series is optimized for general purpose workloads with balanced CPU and memory?

The D-series VMs are optimized for general purpose workloads. They provide a good balance of CPU, memory, and temporary storage for most applications.

What makes the E-series VMs different from the D-series in Azure?

E-series VMs offer more memory per CPU core compared to D-series, making them ideal for memory-intensive applications like databases and analytics.

beginner

For workloads requiring high CPU performance, which Azure VM series is recommended?

The F-series VMs are designed for compute-intensive workloads. They provide higher CPU-to-memory ratio, making them suitable for batch processing and gaming servers.

How do Azure VM series help in choosing the right VM for your workload?

Azure VM series categorize VMs based on workload needs like burstable CPU, balanced compute, memory-optimized, or compute-optimized. This helps pick a VM that matches performance and cost requirements.

Which Azure VM series is best for workloads that need occasional CPU bursts but low baseline usage?

A E-series

B D-series

C B-series

D F-series

B-series VMs accumulate credits during low usage and allow CPU bursting when needed.

Which VM series offers the highest memory per CPU core in Azure?

A E-series

B D-series

C B-series

D F-series

E-series VMs are memory-optimized with more memory per CPU core.

If you need a VM for general purpose workloads with balanced CPU and memory, which series should you choose?

A B-series

B D-series

C E-series

D F-series

D-series VMs provide a balanced CPU and memory configuration for general workloads.

Which Azure VM series is designed for compute-intensive tasks like batch processing?

A B-series

B D-series

C E-series

D F-series

F-series VMs have a higher CPU-to-memory ratio for compute-heavy workloads.

What is a key benefit of choosing the right VM series in Azure?

A It matches workload needs and controls cost

B It guarantees zero downtime

C It automatically scales storage

D It provides unlimited CPU credits

Choosing the right VM series helps balance performance and cost based on workload requirements.
