• D.Cloud Spanner

You are developing a web application that will be accessible over both HTTP and HTTPS and will run on Compute Engine instances. On occasion, you will need to SSH from your remote laptop into one of the Compute Engine instances to conduct maintenance on the app. How should you configure the instances while following Google-recommended best practices?

• A.Configure Cloud Identity-Aware Proxy API for SSH access. Then configure the Compute Engine servers with private IP addresses behind an HTTP(s) load balancer for the application web traffic.
• B.Set up a backend with Compute Engine web server instances with a private IP address behind an HTTP(S) load balancer. Set up a bastion host with a public IP address and open firewall ports. Connect to the web instances using the bastion host.
• C.Configure the firewall rules to allow all ingress traffic to connect to the Compute Engine web servers, with each server having a unique external IP address.
• D.Set up a backend with Compute Engine web server instances with a private IP address behind a TCP proxy load balancer.

You recently migrated an on-premises monolithic application to a microservices application on Google Kubernetes Engine (GKE). The application has dependencies on backend services on-premises, including a CRM system and a MySQL database that contains personally identifiable information (PII). The backend services must remain on-premises to meet regulatory requirements.
You established a Cloud VPN connection between your on-premises data center and Google Cloud. You notice that some requests from your microservices application on GKE to the backend services are failing due to latency issues caused by fluctuating bandwidth, which is causing the application to crash. How should you address the latency issues?

• A.Decrease the network layer packet size by decreasing the Maximum Transmission Unit (MTU) value from its default value on Cloud VPN
• B.Use Memorystore to cache frequently accessed PII data from the on-premises MySQL database
• C.Use Istio to create a service mesh that includes the microservices on GKE and the on-premises services
• D.Increase the number of Cloud VPN tunnels for the connection between Google Cloud and the on-premises services

You work for a financial services company that has a container-first approach. Your team develops microservices applications You have a Cloud Build pipeline that creates a container image, runs regression tests, and publishes the image to Artifact Registry You need to ensure that only containers that have passed the regression tests are deployed to Google Kubernetes Engine (GKE) clusters You have already enabled Binary Authorization on the GKE clusters What should you do next?

• A.Create an attestor and a policy Run a vulnerability scan to create an attestation for the container image as a step in the Cloud Build pipeline.
• B.Set the Pod Security Standard level to Restricted for the relevant namespaces Digitally sign the container images that have passed the regression tests as a step in the Cloud Build pipeline.
• C.Create an attestor and a policy. Create an attestation for the container images that have passed the regression tests as a step in the Cloud Build pipeline.
• D.Deploy Voucher Server and Voucher Client Components. After a container image has passed the regression tests, run Voucher Client as a step in the Cloud Build pipeline.

You are parsing a log file that contains three columns: a timestamp, an account number (a string), and a transaction amount (a number). You want to calculate the sum of all transaction amounts for each unique account number efficiently.
Which data structure should you use?

• A.A hash table
• B.A linked list
• C.A two-dimensional array
• D.A comma-delimited string
