[GCP] Goolge compute Engine

Which of the following is a PAAS option for hosting web apps on GCP?

App Engine standard or flexible environment

Which of the following is a IAAS option for hosting web apps on GCP?

Compute Engine instance

Which of the following is NOT an advantage of containers over VMs?

Control of hardware aspects such as GPUs

What are preemptible instances?

Compute Engine instances that can be asked to terminate processing at 30 seconds notice at any time and so are cheaper than other VMs

When can preemptible instances be used?

For processing-only use in fault tolerant applications

If using preemptible instances, what precaution ought to be taken?

Carry out any clean-up or post-processing in a shutdown script that will be invoked before the instance is pre-empted; ensure this script takes less than 30 seconds to execute

Rank the following storage options from most expensive to cheapest (per GB)

Local SSD > SSD persistent disks > standard persistent > Cloud storage

Rank the following storage options in order of maximum possible storage space per instance

Cloud storage > Persistent (SSD or standard) > Local SSD

Which of the following storage options do NOT offer data redundancy?

In which of the following storage options will data persist only till the instance is stopped or deleted?

Which of the following storage options have limitations on the instance types they can be used with?

Local SSD

Which of the following is typically NOT included in a container?

Operating system kernel

VMs tend to be larger than containers accomplishing similar functionality

True

VMs tend to be faster to start up than containers accomplishing similar functionality

False

Containers tend to be more portable to start up than VMs accomplishing similar functionality

True

Which of the following are advantages of Compute Engine over Container Engine?

Direct access to GPUs for applications such as training TensorFlow machine learning models

What is the main difference between standard persistent disks and SSD persistent disks?

Persistent SSD is a lot faster, particularly for random access

Which of the following is a difference between local SSD and persistent SSD?

Local SSD is actually physically attached to the server hosting the VM instance

Rank the following options in scope of access

Cloud storage - global, persistent (SSD and standard ) - zonal, local SSD - instance

How do storage options differ with container engine instances relative to compute engine instances?

Container disks are ephemeral by default; need to use a specific abstraction to make them persistent

Which of the following best depicts components in a container cluster?

Master endpoint - runs Kubernetes, node instances run Kubelets, each Kubelet controls a pod, pods contain individual Docker containers
