You want your architecture to promote strong security during vehicle operation.
Which two architecture should you consider?
Choose 2 answers:

• A.Use a functional programming language to isolate code execution cycles.
• B.Use multiple connectivity subsystems for redundancy.
• C.Use a trusted platform module (TPM) and verify firmware and binaries on boot.
• D.Enclose the vehicle's drive electronics in a Faraday cage to isolate chips.
• E.Require IPv6 for connectivity to ensure a secure address space.
• F.Treat every micro service call between modules on the vehicle as untrusted.

You are developing your microservices application on Google Kubernetes Engine. During testing, you want to validate the behavior of your application in case a specific microservice should suddenly crash. What should you do?

• A.Use Istio's fault injection on the particular microservice whose faulty behavior you want to simulate.
• B.Add a taint to one of the nodes of the Kubernetes cluster. For the specific microservice, configure a pod anti-affinity label that has the name of the tainted node as a value.
• C.Destroy one of the nodes of the Kubernetes cluster to observe the behavior.
• D.Configure Istio's traffic management features to steer the traffic away from a crashing microservice.

You are tasked with building an online analytical processing (OLAP) marketing analytics and reporting tool. This requires a relational database that can operate on hundreds of terabytes of data. What is the Google- recommended tool for such applications?

• A.Cloud Spanner, because it is globally distributed
• B.BigQuery, because it is designed for large-scale processing of tabular data
• C.Cloud Firestore, because it offers real-time synchronization across devices
• D.Cloud SQL, because it is a fully managed relational database

Your architecture calls for the centralized collection of all admin activity and VM system logs within your
project.
How should you collect these logs from both VMs and services?

• A.All admin and VM system logs are automatically collected by Stackdriver.
• B.Stackdriver automatically collects admin activity logs for most services. The Stackdriver Logging agent
  must be installed on each instance to collect system logs.
• C.Launch a custom syslogd compute instance and configure your GCP project and VMs to forward all
  logs to it.
• D.Install the Stackdriver Logging agent on a single compute instance and let it collect all audit and access
  logs for your environment.
