You have created a Cloud Router and two encrypted VLAN attachments that have a 5 Gbps capacity and a BGP configuration. The BGP sessions are operational. You need to complete the deployment of the HA VPN over Cloud Interconnect. What should you do?

You have recently taken over responsibility for your organization's Google Cloud network security configurations. You want to review your Cloud Next Generation Firewall (Cloud NGFW) configurations to ensure that there are no rules allowing ingress traffic to your VMs and services from the internet. You want to avoid manual work. What should you do?

Your organization is connecting their Shared VPC network to their on-premises data center by using Dedicated Interconnect to provide connectivity to all of its service projects. You need to create a design to configure your VLAN attachments and Cloud Routers. You also want to achieve a 99.9% Cloud Interconnect SLA based on Google Cloud s reference design. What should you do?

Your organization's on-premises networking team is reporting frequent BGP session flaps toward your Google Cloud environment. You need to review the BGP configuration. What should you do?

Your organization has over 250 autonomous business units that currently operate in a decentralized manner. Due to the organization's maturity, there is limited routable private IP address space, which is insufficient to accommodate all of the necessary workloads. You need to create a cloud-first network design that uses the same IP address space across business unit workloads where possible. These business units require communication between units, and access to their on-premises data center. What should you do?

You are configuring an Application Load Balancer. The backend resides in your on-premises data center and is connected by Dedicated Interconnect. You need to ensure the load balancer can reference these on-premises resources. You do not want the traffic to traverse the internet at all. What should you do?

You are troubleshooting connectivity issues between Google Cloud and a public SaaS provider. Connectivity between the two environments is through the public internet. Your users are reporting intermittent connection errors when using TCP to connect; however, ICMP tests show no failures. According to users, errors occur around the same time every day. You want to troubleshoot and gather information by using Google Cloud tools that are most likely to provide insights to what is occurring within Google Cloud. What should you do?

You configured a single IPSec Cloud VPN tunnel for your organization to a third-party customer. You confirmed that the VPN tunnel is established. However, the BGP session status states that the BGP is not configured. The customer has provided you with their BGP settings: • Local BGP address: 169.254.11.1/30 • Local ASN: 64515 • Peer BGP address: 169.254.11.2 • Peer ASN: 64517 • Base MED: 1000 • MD5 Authentication: Disabled You need to configure the local BGP session for this tunnel based on the settings provided by the customer. You already associated the Cloud Router with the Cloud VPN Tunnel. What settings should you use for the BGP session?

Your organization's current architecture has one Shared VPC host project (SH_HOST_PRJ) that contains a single VPC (SH_VPC) and two Shared VPC service projects (SP_ONE_PRJ and SP_TWO_PRJ) that do not contain any VPCs. Each Shared VPC service project belongs to a different team: TEAM_ONE manages SP_ONE_PRJ and TEAM_TWO manages SP_TWO_PRJ. You must design a solution that allows each team to create their own DNS private zones and DNS records only in their respective Shared VPC service projects. Workloads in SP_ONE_PRJ must be able to resolve all the DNS private zones defined in SP_TWO_PRJ and conversely. Your design must have the least amount of set up effort. What should you do?

You are troubleshooting an application in your organization's Google Cloud network that is not functioning as expected. You suspect that packets are getting lost somewhere. The application sends packets intermittently at a low volume from a Compute Engine VM to a destination on your on-premises network through a pair of Cloud Interconnect VLAN attachments. You validated that the Cloud Next Generation Firewall (Cloud NGFW) rules do not have any deny statements blocking egress traffic, and you do not have any explicit allow rules. Following Google-recommended practices, you need to analyze the flow to see if packets are being sent correctly out of the VM to isolate the issue. What should you do?

Your organization is launching a new video game that will be available to all users globally through Cloud CDN. During the earl y release phase, you discovered that the wrong binary version was uploaded from Cloud Storage and cached in Cloud CDN. Thousands of users have downloaded the wrong version. Your marketing department has notified users that this was the wrong version of the game and asked all users to download the updated version using the same URL. You need to ensure users are downloading the updated version of the game. What should you do?

You recently reviewed the user behavior for your main application, which uses an external global Application Load Balancer, and found that the backend servers were overloaded due to erratic spikes in the rate of client requests. You need to limit the concurrent sessions and return an HTTP 429 Too Many Requests response back to the client while following Google-recommended practices. What should you do?

Your company uses web application firewall (WAF) capabilities from a third-party cloud WAF provider. This WAF provider proxies all the HTTPS connections from internet clients, applies security policies, and then opens a new HTTPS connection to the public IP address of your global Application Load Balancer in Google Cloud. Your Google Cloud workloads are the backend of this global Application Load Balancer. Currently, Cloud Am1or is not configured. You need to create a Cloud Armor security policy that blocks sessions that originate from internet clients with source IP addresses that belong to the IP_RANGE_BLOCK IP range. The block must be executed by the Cloud Armor security policy; it will not be done by the third-party cloud WAF provider. Whal should you do?

Your organization, TerramEarth, is launching a global application to manage credit card payments. There are some client VMs inside the same VPC as the application that need to access this application privately. Due to compliance requirements, the internal clients cannot use the global external IP address of the application. Currently, Cloud DNS only resolves myglobalapp.terramearth.com to the public IP address with a public zone. The clients will need to reach myglobalapp.example.com, without using its external IP address. You need to configure Cloud DNS to follow this requirement while following Google-recommended practices. What should you do?

You are setting up a Dedicated Interconnect connection from your organization’s on-premises data center in Frankfurt, Germany, towards the europe-west3 region, which is also in the Frankfurt metropolitan area. The AI team lead expressed their concern regarding connectivity to the europe-west4 region because their team wants to use Google Cloud TPUs for their workloads. You need to ensure that low latency network connectivity is established for this team’s workloads. You want to minimize costs and operational overhead. What should you do?

Your company uses VPC firewall rules and denies all egress traffic. You need to allow some VMs to contact external websites based on their fully qualified domain name (FQDN). You apply the new configuration, but the traffic is still denied. You need to adjust your setup to apply the new configuration. What would you do?

Your VPC is configured with regional dynamic routing mode. You have deployed VMs and VLAN attachments in the europe-west2 region, and regional internal Application Load Balancers in us-east1. You need to ensure the VMs in the europe-west2 region have connectivity to the regional internal Application Load Balancers in the us-east1 region. What should you do?

You are designing the architecture for your organization so that clients can connect to certain Google APIs. Your plan must include a way to connect to Cloud Storage and BigQuery. You also need to ensure the traffic does not traverse the internet. You want your solution to be cloud-first and require the least amount of configuration steps. What should you do?
