Your company is running the majority of its workloads in a co-located data center. The workloads are running on virtual machines (VMs) on top of a hypervisor and use either Linux or Windows server editions. As part of your company’s transformation strategy, you need to modernize workloads as much as possible by adopting cloud-native technologies. You need to migrate the workloads into Google Cloud.
What should you do?
- A . Export the VMs into VMDK format, and import them into Compute Engine
- B . Export the VMs into VMDK format, and import them into Google Cloud VMware Engine
- C . Migrate the workloads using Migrate for Compute Engine
- D . Migrate the workloads using Migrate for Anthos
D
Explanation:
Anthos: Anthos lets you build, deploy, and manage applications anywhere in a secure, consistent manner. You can modernize existing applications running on virtual machines while deploying cloud-native apps on containers in an increasingly hybrid and multi-cloud world.
Customer Managed Encryption Keys (CMEK) can be used for encrypting data inside Cloud BigTable, which of the following statements is/are correct. (Select two answer)
- A . Administrators can not rotate
- B . Not supported for instances that have clustered in more than one region.
- C . CMEK can only be configured at the cluster level.
- D . You can not use the same CMEK key in multiple projects
BC
Explanation:
Customer-managed encryption keys for Cloud BigTable.
By default, all the data at rest in Cloud Bigtable is encrypted using Google’s default encryption.
Bigtable handles and manages this encryption for you without any additional action on your part.
If you have specific compliance or regulatory requirements related to the keys that protect your data, you can use customer-managed encryption keys (CMEK) for BigTable. Instead of Google managing the encryption keys that protect your data, your BigTable instance is protected using a key that you control and manage in Cloud Key Management Service (Cloud KMS).
Features
Security: CMEK provides the same level of security as Google’s default encryption but provides more administrative control.
Data access control: Administrators can rotate, manage access to, and disable or destroy the key used to protect data at rest in BigTable.
Auditability: All actions on your CMEK keys are logged and viewable in Cloud Logging. Comparable performance: BigTable CMEK-protected instances offer comparable performance to BigTable instances that use Google default encryption.
Flexibility: You can use the same CMEK key in multiple projects or instances or you can use separate keys, depending on your business needs.
An organization is building advanced machine learning models in Google Cloud by using TensorFlow. They want to develop their models faster with purpose-built hardware.

What is a key difference between VMs and containers?
- A . Virtual Machines take less time to launch; containers take longer to launch.
- B . Virtual Machines can only run Linux; containers can run any operating system.
- C . Virtual Machines use a shared operating system and are therefore lighter; containers are heavier on resources.
- D . Each Virtual Machine in a machine has its own operating system; containers will share the same operating system.
D
Explanation:
VMs have their individual OSs. All containers on a node use the host operating system.

A customer in the European Union region is very clear that their data should not go outside the Eu-ropean Union. Their end users are spread all over the European U. They have to choose a storage option that serves all the users within Asia via web browsers as quickly as possible.
Which storage option will work for them?
- A . Cloud Storage with a single region that is known to be within the European U
- B . Cloud Filestore is connected to virtual machines which are guaranteed to be within the European U
- C . Cloud Storage with the multi-region option of European U
- D . Cloud Storage with the dual-region option of European U
C
Explanation:
Multi-region option will use multiple datacenters that are within the European Union. More regions
will also help with lower latency since users are spread across the European U.
