Google Cloud Digital Leader Exam Questions Instant Access

Question 1

Your customer currently has a hybrid cloud setup including their on-premises data center and AWS. They are consolidating all their services on Google Cloud as part of a modernization plan and want to spend less IT effort in the future. There are about 10 MySQL and 25 PostgreSQL databases across the two DCs. What is the best option to for them?

AUse the Data Catalog Service to manage the metadata of the databases

BUse Cloud Dataflow service and setup Google's Cloud SQL as the sink and the others as the source, which will cause the data to flow in as expected.

CUse the Database Migration Service

DUse the Bare Metal Solution and copy the databases directly as they are on-premises and on AWS.

Answer : C

Explanation

Database Migration is the right one to use: 'Simplifying migrations to Cloud SQL. Now available for MySQL and PostgreSQL migrations, with SQL Server coming soon.' Since the customer also doesn't want to manage their own database installations in the future, Cloud SQL is the best option.

Question 2

A partner of yours used to have their own private data center. Your company was already on Google Cloud and now they have also moved to Google Cloud. You are investigating whether there are ways to collaborate better or shared services. What would be one good option to consider?

AUse Private Service Access within Google Cloud.

BUse VPC Peering to share resources privately between your two organizations.

CUse public IP addresses as before. It will automatically be routed internally only.

DUse VPC Shared Networks to share common resources.

Answer : B

VPC Network Peering allows internal IP address connectivity across two Virtual Private Cloud (VPC) networks regardless of whether they belong to the same project or the same organization.

-> Shared VPC is only within an organization - it allows an organization to connect resources from multiple projects to a common Virtual Private Cloud (VPC) network, so that they can communicate with each other securely and efficiently using internal IPs from that network.

->Private Google Access is only to access Google APIs and services

Question 3

Your organization wants to run a container-based application on Google Cloud. This application is expected to increase in complexity. You have a security need for fine-grained control of traffic between the containers. You also have an operational need to exercise fine-grained control over the application's scaling policies.

What Google Cloud product or feature should your organization use?

AGoogle Kubernetes Engine cluster

BApp Engine

CCloud Run

DCompute Engine virtual machines

Answer : A

Google Kubernetes Engine GKE seems a better fit since the requirement is for 'security need for fine-grained control of traffic between the containers' and 'fine-grained control over scaling policies'. Such level of control is easier on GKE that Cloud Run.

Question 4

How should a multinational organization that is migrating to Google Cloud consider security and privacy regulations to ensure that it is in compliance with global standards?

AComply with data security and privacy regulations in each geographical region

BComply with regional standards for data security and privacy, because they supersede all international regulations

CComply with international standards for data security and privacy, because they supersede all regional regulations

DComply with regional data security regulations, because they're more complex than privacy standards

Answer : A

Comply with data security and privacy regulations in each geographical regionFor a multi-national corporation, they need to abide not just by international laws, but also regional laws where they do business.

Question 5

Which of the following is / are true for Preemptible Instances.

APreemptible Instances have no Service Level Agreement (Compute Engine SLA).

BGoogle Cloud Free Tier credits for compute engine do not apply to preemptible in-stances.

CPreemptible instances can't live migrate to a regular VM instance, or be set to au-tomatically restart when there is a maintenance event.

DAll of the above.

Answer : D

Preemptible instances function like normal instances but have the following limitations:

->Compute Engine might stop preemptible instances at any time due to system events. The probability that Compute Engine will stop a preemptible instance for a system event is generally low, but might vary from day to day and from zone to zone depending on current conditions.

->Compute Engine always stops preemptible instances after they run for 24 hours. Certain actions reset this 24-hour counter.

->Preemptible instances are finite Compute Engine resources, so they might not always be available.

->Preemptible instances can't live migrate to a regular VM instance, or be set to automatically restart when there is a maintenance event.

->Due to the above limitations, preemptible instances are not covered by any Service Level Agreement (and, for clarity, are excluded from the Compute Engine SLA).

->The Google Cloud Free Tier credits for Compute Engine do not apply to preemptible instances.

Question 6

Which Firebase quality tools help the developer track, prioritize & fix stability issues that erode the application quality?

APerformance

BApp Distribution

CCrashlytics

DTest Lab

Answer : C

Firebase Crashlytics:

Get clear, actionable insight into app issues with this powerful crash reporting solution for iOS, Android, and Unity.

Firebase Crashlytics is a lightweight, real-time crash reporter that helps you track, prioritize, and fix stability issues that erode your app quality. Crashlytics saves you troubleshooting time by intelligently grouping crashes and highlighting the circumstances that lead up to them.

Find out if a particular crash is impacting a lot of users. Get alerts when an issue suddenly increases in severity. Figure out which lines of code are causing crashes.

Question 7

After rolling out a new update, an organization found a minor bug in its online video game.

How should the organization approach this bug while following SRE principles?

AAccept and learn from the bug because failure is normal

BAccept and ignore the bug because it is only minor

CHold a postmortem to reprimand the employee responsible for the bug

DDocument bug correction to eliminate all future bugs

Answer : A

https://www.blameless.com/sre/sre-principles

Accepting failure as normal is one of the SRE principles. SREs believe that accepting failure as normal helps to build an iterative, collaborative culture. One way this is done is by holding a blameless ''lessons learned'' discussion after an incident occurs.
