You work for a manufacturer of specialty die cast parts for the aerospace industry. The company has built a reputation as the leader in high-quality, specialty die cast parts, but recently the number of parts returned for poor quality is increasing. Detailed data about the manufacturing process is collected throughout every stage of manufacturing. To date, the data has been collected and stored but not analyzed. There is a total of 20 TB of data. The company has a team of analysts familiar with spreadsheets and SQL. What service might you recommend for conducting preliminary analysis of the data?Compute EngineKubernetes EngineBigQueryCloud Functions15 A client of yours wants to run an application in a highly secure environment. They want to use instances that will only run boot components verified by digital signatures.

16 You have installed the Google Cloud SDK. You would now like to work on transferring files to Cloud Storage. What command-line utility would you use?bqgsutilcbtgcloud
17 Kubernetes pods sometimes need access to persistent storage. Pods are ephemeral—they may shut down for reasons not in control of the application running in the pod. What mechanism does Kubernetes use to decouple pods from persistent storage?PersistentVolumesDeploymentsReplicaSetsIngress
18 An application that you support has been missing service-level objectives, especially around database query response times. You have reviewed monitoring data and determined that a large number of database read operations is putting unexpected load on the system. The database uses PostgreSQL, and it is running in Compute Engine. You have tuned SQL queries, and the performance is still not meeting objectives. Of the following options, which would you try next?Migrate to a NoSQL database.Move the database to Cloud SQL.Use read replicas.Move some of the data out of the database to Cloud Storage.
19 You are running a complicated stream processing operation using Apache Beam. You want to start using a managed service. What GCP service would you use?Cloud DataprepCloud DataprocCloud DataflowCloud Identity
20 Your team has had several incidents in which Tier 1 and Tier 2 services were down for more than one hour. After conducting a few retrospective analyses of the incidents, you have determined that you could identify the causes of incidents faster if you had a centralized log repository. What GCP service could you use for this?Cloud LoggingCloud MonitoringCloud SQLCloud Trace
21 A Global 2000 company has hired you as a consultant to help architect a new logistics system. The system will track the location of parts as they are shipped between company facilities in Europe, Africa, South America, and Australia. Anytime a user queries the database, they must receive accurate and up-to-date information; specifically, the database must support strong consistency. Users from any facility may query the database using SQL. What GCP service would you recommend?Cloud SQLBigQueryCloud SpannerCloud Dataflow
22 A database architect for a game developer has determined that a NoSQL document database is the best option for storing players’ possessions. What GCP service would you recommend?Cloud FirestoreCloud StorageCloud DataprocCloud Bigtable
23 A major news agency is seeing increasing readership across the globe. The CTO is concerned that long page-load times will decrease readership. What might the news agency try to reduce the page-load time of readers around the globe?Regional Cloud StorageCloud CDNFewer firewall rulesVirtual private network
24 What networking mechanism allows different VPC networks to communicate using private IP address space, as defined in RFC 1918?ReplicaSetsCustom subnetsVPC network peeringFirewall rules
25 You have been tasked with setting up disaster recovery infrastructure in the cloud that will be used if the on-premises data center is not available. What network topology would you use for a disaster recovery environment?Meshed topologyMirrored topologyGated egress topologyGated ingress topology
Answers to the Assessment Test
1 B. Option B is correct. Bigtable is the best option for streaming IoT data, since it supports low-latency writes and is designed to scale to support petabytes of data.Option A is incorrect because Apache Cassandra is not a managed database in GCP. Option C is incorrect because BigQuery is a data warehouse. While it is a good option for analyzing large volumes of data, Bigtable is a better option for ingesting the data. Option D is incorrect. CloudSQL is a managed relational database. The use case does not require a relational database, and Bigtable's scalability is a better fit with the requirements.
2 C. The correct answer is C. A Cloud Pub/Sub topic would decouple the front end and backend, provide a managed and scalable message queue, and store ingested data until the backend can process it.Option A is incorrect. Switching to an unmanaged instance group will mean that the instance group cannot autoscale. Option B is incorrect. You could store ingested data in Cloud Storage, but it would not be as performant as the Cloud Pub/Sub solution. Option D is incorrect because BigQuery is a data warehouse and not designed for this use case.
3 B. The correct answer is B. IAM is used to manage roles and permissions.Option A is incorrect. Cloud Identity is a service for creating and managing identities. Option C is incorrect. There is no GCP service with that name at this time. Option D is incorrect. LDAP is not a GCP service.
4 B. The correct answer is B. You can run custom stateless containers in App Engine Flexible, Cloud Run, and Kubernetes Engine.Option A is incorrect because App Engine Standard does not support custom containers. Option C is incorrect because Compute Engine is not a managed service and Cloud Functions does not support custom containers. Option D is incorrect because Cloud Functions does not support custom containers.
5 A. The correct answer is A. A Cloud Function can respond to a create file event in Cloud Storage and start processing when the file is created.Option B is incorrect because an App Engine Flexible application cannot directly respond to a Cloud Storage write event. Option C is incorrect. Kubernetes pods are the smallest compute unit in Kubernetes and are not designed to directly respond to Cloud Storage events. Option D is incorrect because it does not guarantee that photos will be processed as soon as they are created.
6 B. The correct answer is B. BigQuery is a managed analytics database designed to support data warehouses and similar use cases.Option A is incorrect. Compute Engine is not a managed service. Option C is incorrect. Cloud Dataproc is a managed Hadoop and Spark service. Option D is incorrect. Bigtable is a NoSQL database well suited for large-volume, low-latency writes and limited ranges of queries. It is not suitable for the kind of ad hoc querying commonly done with data warehouses.
7 C. The correct answer is C. Cloud Storage Archive is the lowest-cost option, and it is designed for data that is accessed less than once per year.Options A and B are incorrect because they cost more than Archive storage. Option D is incorrect because there is no such service.
8 C. The correct answer is C. The GDPR is a European Union directive protecting the personal information of EU citizens.Option A is incorrect. HIPAA is a US healthcare regulation. Option B is incorrect. PCI-DS is a payment card data security regulation; if Global Games Enterprises Inc. is accepting payment cards in North America, it is already subject to that regulation. Option D is a US regulation on some publicly traded companies; the company may be subject to that regulation already, and expanding to Europe will not change its status.
9 A. The correct answer is A. Cloud SQL is a managed database service that supports PostgreSQL.Option B is incorrect. Cloud Dataproc is a managed Hadoop and Spark service. Option C is incorrect. Cloud Bigtable is a NoSQL database. Option D is incorrect. There is no service called Cloud PostgreSQL in GCP at this time.
10 A. The correct
