GCP PCA · Question 41 · Domain 2: Managing and Provisioning a Solution Infrastructure

You are provisioning storage for Compute Engine instances. You need to select the appropriate Persistent Disk (PD) types. Which TWO statements accurately describe GCP Persistent Disk options? (Select TWO)

Answer options:

A.

Standard PD (pd-standard) is best for sequential I/O operations and large data processing.

B.

Balanced PD (pd-balanced) provides the highest possible IOPS for extreme database workloads.

C.

Persistent Disks cannot be resized without detaching them from the VM.

D.

Regional Persistent Disks synchronously replicate data across two zones in the same region.

E.

Local SSDs provide persistent storage that survives VM termination.

How to approach this question

Review the types of block storage: Standard (HDD), Balanced (SSD), Performance (SSD), Extreme, and Regional PDs.

Full Answer

A,D
Standard Persistent Disks (pd-standard) use hard disk drives (HDDs) and are optimized for sequential I/O and low cost. Regional Persistent Disks provide active-active synchronous replication across two zones, which is the foundational technology behind Cloud SQL High Availability. Local SSDs are extremely fast but ephemeral (not persistent).

Common mistakes

Confusing Local SSDs with Persistent Disks (E). Local SSDs are physically attached to the host server and lose data on termination.
