Question # 42

With respect to the Core Feature of Standby Instances of Cloud SQL which one of the options is correct.?

The standby instance is used in high availability to replace the primary instance when failover occurs. The standby instance appears in the Google Cloud Console but does not get billed. When failover occurs, connections to the primary instance need to be manually transferred to the standby instance.

The standby instance is used in high availability to replace the primary instance when failover occurs. The standby instance appears in the Google Cloud Console but does not get billed. When failover occurs, connections to the primary instance are automatically transferred to the standby instance.

The standby instance is used in high availability to replace the primary instance when failover occurs. The standby instance doesn ' t appear in the Google Cloud Console. When failover occurs, connections to the primary instance are automati-cally transferred to the standby instance.

None of the Above.

Answer:

Explanation:

Cloud SQL Key Terms:

Cloud SQL instance

A Cloud SQL instance corresponds to one virtual machine (VM). The VM includes the database instance and accompanying software containers to keep the database instance up and running.

Database instance

A database instance is the set of software and files that operate the databases: MySQL, PostgreSQL or SQL Server.

High availability

Cloud SQL instances using high availability (HA) provide greater reliability than non-HA instances.

HA in Cloud SQL works by having two synchronized instances: a primary instance and a standby instance. Each instance has exactly one VM. Each instance is in a different zone in the same region.

Failover

A failover is when Cloud SQL switches serving from the original primary instance to the standby instance.

Autofailover is a mechanism that automatically triggers failover when a Cloud SQL instance didn ' t issue a heartbeat in the previous interval.

Standby instances

Clone

When you clone a Cloud SQL instance, you create a new instance that is a copy of the source instance, but is completely independent. After cloning is complete, changes to the source instance are not reflected in the clone, and changes in the clone are not reflected in the source instance.

Replication

Replication is the ability to create copies of a Cloud SQL instance or an on-premises database, and offload work to the copies. The main reason for using replication is to scale the use of data in a database without degrading performance on the primary instance.

Read replica

The read replica is an exact copy of the primary instance. Data and other changes on the primary instance are updated in almost real time on the read replica. Send your write transactions to the primary instance, and your read requests to the read replica. The read replica processes queries, read requests, and analytics traffic, thus reducing the load on the primary instance.

Source server

Replication copies transactions from a primary instance to one or more read replicas. The primary instance is also called the source server. The source server can be a Cloud SQL primary instance, or a server outside of Google Cloud, such as an on-premises server or a server running in a different cloud. If the source server is outside of Google Cloud, we call it Replication from an external server.

Cloud SQL Auth proxy client

The Cloud SQL Auth proxy client is open source software maintained by Cloud SQL. It connects to a companion process, the Cloud SQL Auth proxy server, running on your Cloud SQL instance. You run the Cloud SQL Auth proxy client on your own servers. The Cloud SQL Auth proxy client can be used to establish a secure SSL/TLS connection to the database instance, and/or to avoid having to open the firewall. Authentication is done through Identity and Access Management (IAM).

Question # 43

An application has become very popular and the number of requests/users is increasing quickly. There is a meeting to figure out how to scale the systems so that they can accept user requests and still have the capacity to spare. What is the preferred option?

Circular Scaling takes a round-robin approach to allocate and destroy VMs.

Triangular Scaling takes an automated average of Cost, Effort, and Time.

Vertical Scaling

Horizontal Scaling

Question # 44

An organization wants to measure everything as part of its new DevOps philosophy. What should the organization measure?

The reliability and health of their systems.

The satisfaction and happiness of their employees.

The risk and reward of their investments.

The speed of their cloud adoption process.

Question # 45

You have deployed a new public web application that allows users to register and login with email ids, phone numbers, or user ids. You are seeing some unusual activity with user registrations and logins from a few IPs. A large number of accounts were created very quickly. Logins are also hap-pening quickly thereafter from these new accounts. Different parts of the application are being ex-plored, all of which are putting a heavy load on the application. What could be a problem and how can you solve it?

A hacker group has hired a bunch of people to create accounts and manually use the system. Use Cloud Asset Inventory to see if there have been changes in the inventory.

Bots are creating accounts and then using them. Use Google Cloud ' s Web App and API Protection (WAAP).

Bots are creating accounts and then using them. Use Identity-Aware Proxy to re-strict the users to known users.

Automated testing tools might still be running and creating accounts. Use Identity-Aware Proxy to restrict the users to known users.

Question # 46

Classification

De-identification

Committed-Use

Sustained-Use

Preemptible VMs

Question # 48

In discussions with a prospective customer who wants to move to Google Cloud to make use of the latest, scalable technologies available therein, you learn that there are very strict regulations concern-ing the storage of data. They only have the approval to store it in their current private data cen-ter. What would you advise them?

Retain on-premise itself those portions of data and compute which are under regulation. Take advantage of all the other cloud capabilities for remaining work-loads.

It is too risky to touch anything in such a scenario. It is best to remain entirely on-premise.

Regulations are guidelines. As long as the data remains encrypted, you can move it anywhere.

Petition the government for changes to such regulations as all industries are mov-ing to the public cloud. Then, when the regulations are eased, move to Google Cloud.

Question # 49

You are a cloud architect in a software solution provider company, one of the client that is a Na-tional Bank who wants to build an application that deals with transactions processing, and it needs a relational database with petabyte of scale data. Which of the following Google Cloud Services will you use?

Cloud SQL

Cloud Bigtable

Cloud Spanner

Google Cloud BigQuery
