A : u expect to store at least 10 TB of data.

B : u will mostly run batch workloads with scans and writes, rather than frequently executing random reads of a small number of rows.

C : u need to integrate with Google BigQuery.

D : u will not use the data to back a user-facing or latency-sensitive application.

Answer: C

Question 2

When you store data in Cloud Bigtable, what is the recommended minimum amount of stored data?

A : 500 TB

B : 1 GB

C : 1 TB

D : 500 GB

Answer: C

Question 3

You are part of a healthcare organization where data is organized and managed by respective data owners in

various storage services. As a result of this decentralized ecosystem, discovering and managing data has

become difficult You need to quickly identify and implement a cost-optimized solution to assist your

organization with the following

• Data management and discovery

• Data lineage tracking

• Data quality validation

How should you build the solution?

A : Use BigLake to convert the current solution into a data lake architecture.

B : Build a new data discovery tool on Google Kubernetes Engine that helps with new source onboarding and data lineage tracking

C : Use BigOuery to track data lineage, and use Dataprep to manage data and perform data quality validation

D : Use Dataplex to manage data, track data lineage, and perform data quality validation.

Answer: D

Question 4

As your organization expands its usage of GCP, many teams have started to create their own projects. Projects are further multiplied to accommodate different stages of deployments and target audiences. Each project requires unique access control configurations. The central IT team needs to have access to all projects. Furthermore, data from Cloud Storage buckets and BigQuery datasets must be shared for use in other projects in an ad hoc way. You want to simplify access control management by minimizing the number of policies. Which two steps should you take? Choose 2 answers.

A : Cloud Deployment Manager to automate access provision.

B : troduce resource hierarchy to leverage access control policy inheritance.

C : eate distinct groups for various teams, and specify groups in Cloud IAM policies.

D : ly use service accounts when sharing data for Cloud Storage buckets and BigQuery datasets.

E : r each Cloud Storage bucket or BigQuery dataset, decide which projects need access. Find all the active members who have access to these projects, and create a Cloud IAM policy to grant access to all these users.

Answer: A,C

Question 5

You stream order data by using a Dataflow pipeline, and write the aggregated result to Memorystore. You

provisioned a Memorystore for Redis instance with Basic Tier. 4 GB capacity, which is used by 40 clients for

read-only access. You are expecting the number of read-only clients to increase significantly to a few hundred

and you need to be able to support the demand. You want to ensure that read and write access availability is

not impacted, and any changes you make can be deployed quickly. What should you do?

A : Create multiple new Memorystore for Redis instances with Basic Tier (4 GB capacity) Modify theDataflow pipeline and new clients to use all instances

B : Create a new Memorystore for Redis instance with Standard Tier Set capacity to 4 GB and read replicato No read replicas (high availability only). Delete the old instance.

C : Create a new Memorystore for Memcached instance Set a minimum of three nodes, and memory pernode to 4 GB. Modify the Dataflow pipeline and all clients to use the Memcached instance Delete theold instance.

D : Create a new Memorystore for Redis instance with Standard Tier Set capacity to 5 GB and createmultiple read replicas Delete the old instance.
