1. As a developer, you foresee the need to have a load balancer that can distribute load using only private RFC 1918 addresses. Which load balancer would you use?

2. A data warehouse service running in GCP has all of its resources in a single project. The e-commerce application has resources in another project, including a database with transaction data that will be loaded into the data warehouse. The data warehousing team would like to read data directly from the database using extraction, transformation, and load processes that run on Compute Engine instances in the data warehouse project. Which of the following network constructs could help with this?

3. A startup is designing a social site dedicated to discussing global political, social, and environmental issues. The site will include news and opinion pieces in text and video. The startup expects that some stories will be exceedingly popular, and others won’t be, but they want to ensure that all users have a similar experience with regard to latency, so they plan to replicate content across regions. What load balancer should they use?

4. Several new firewall rules have been added to a VPC. Several users are reporting unusual problems with applications that did not occur before the firewall rule changes. You’d like to debug the firewall rules while causing the least impact on the network and doing so as quickly as possible. Which of the following options is best?

5. Your team has deployed a VPC with default subnets in all regions. The lead network architect at your company is concerned about possible overlap in the use of private addresses. How would you explain how you are dealing with the potential problem?

6. Network engineers have determined that a link between the on-premises network and GCP will require a connection between 60 Gbps and 80 Gbps. Which hybrid-cloud networking services would best meet this requirement?

7. An executive wants to understand what changes in the current cloud architecture are required to run compute-intensive machine learning workloads in the cloud and have the models run in production using on-premises servers. The models are updated daily. There is no network connectivity between the cloud and on-premises networks. What would you tell the executive?

8. To comply with regulations, you need to deploy a disaster recovery site that has the same design and configuration as your production environment. You want to implement the disaster recovery site in the cloud. Which topology would you use?

9. Network engineers have determined that the best option for linking the on-premises network to GCP resources is by using an IPsec VPN. Which GCP service would you use in the cloud?

10. The network administrator at your company has asked that you configure a firewall rule that will always take precedence over any other firewall rule. What priority would you assign?

11. During a review of a GCP network configuration, a developer asks you to explain CIDR notation. Specifically, what does the 8 mean in the CIDR block 172.16.10.2/8?

12. Network engineers have determined that a link between the on-premises network and GCP will require an 8 Gbps connection. Which option would you recommend?

13. After a thorough review of the options, a team of developers and network engineers have determined that the SSL Proxy load balancer is the best option for their needs. What other GCP service must they have to use the SSL Proxy load balancer?

14. An intern working with your team has changed some firewall rules. Prior to the change, all Compute Engine instances on the network could connect to all other instances on the network. After the change, some nodes cannot reach other nodes. What might have been the change that causes this behavior?

15. The director of network engineering has determined that any links to networks outside of the company data center will be implemented at the level of BGP routing exchanges. What hybrid-cloud networking option should you use?
