Your company security policy mandates that virtual machines (VMs) must not have public IP addresses attached to them. You need to allow your instances to fetch updates from the internet while preventing external access. What should you do?
  1. Create a Cloud NAT gateway and Cloud Router in both us-west1 and us-east1.
  2. Create a single global Cloud NAT gateway and global Cloud Router in the VPC.
  3. Change the instances' network interface external IP address from None to Ephemeral.
  4. Create a firewall rule that allows egress to destination 0.0.0.0/0.
Correct answer: A
Question 4
Your company has provisioned 2000 virtual machines (VMs) in the private subnet of your Virtual Private Cloud (VPC) in the us-east1 region. You need to configure each VM to have a minimum of 128 TCP connections to a public repository so that users can download software updates and packages over the internet. You need to implement a Cloud NAT gateway so that the VMs are able to perform outbound NAT to the internet. You must ensure that all VMs can simultaneously connect to the public repository and download software updates and packages. Which two methods can you use to accomplish this? (Choose two.)
  1. Configure the NAT gateway in manual allocation mode, allocate 2 NAT IP addresses, and update the minimum number of ports per VM to 256.
  2. Create a second Cloud NAT gateway with the default minimum number of ports configured per VM to 64.
  3. Use the default Cloud NAT gateway's NAT proxy to dynamically scale using a single NAT IP address.
  4. Use the default Cloud NAT gateway to automatically scale to the required number of NAT IP addresses, and update the minimum number of ports per VM to 128.
  5. Configure the NAT gateway in manual allocation mode, allocate 4 NAT IP addresses, and update the minimum number of ports per VM to 128.
Correct answer: AB
Question 5
You have the following routing design. You discover that Compute Engine instances in Subnet-2 in the asia-southeast1 region cannot communicate with compute resources on-premises. What should you do?
  1. Configure a custom route advertisement on the Cloud Router.
  2. Enable IP forwarding in the asia-southeast1 region.
  3. Change the VPC dynamic routing mode to Global.
  4. Add a second Border Gateway Protocol (BGP) session to the Cloud Router.
Correct answer: C
Question 6
You are designing a hybrid cloud environment for your organization. Your Google Cloud environment is interconnected with your on-premises network using Cloud HA VPN and Cloud Router. The Cloud Router is configured with the default settings. Your on-premises DNS server is located at 192.168.20.88 and is protected by a firewall, and your Compute Engine resources are located at 10.204.0.0/24. Your Compute Engine resources need to resolve on-premises private hostnames using the domain corp.altostrat.com while still resolving Google Cloud hostnames. You want to follow Google-recommended practices. What should you do?
  1. Create a private forwarding zone in Cloud DNS for 'corp.altostrat.com' called corp-altostrat-com that points to 192.168.20.88.
    Configure your on-premises firewall to accept traffic from 10.204.0.0/24.
    Set a custom route advertisement on the Cloud Router for 10.204.0.0/24
  2. Create a private forwarding zone in Cloud DNS for 'corp.altostrat.com' called corp-altostrat-com that points to 192.168 20.88.
    Configure your on-premises firewall to accept traffic from 35.199.192.0/19 Set a custom route advertisement on the Cloud Router for 35.199.192.0/19.
  3. Create a private forwarding zone in Cloud DNS for 'corp .altostrat.com' called corp-altostrat-com that points to 192.168.20.88.
    Configure your on-premises firewall to accept traffic from 10.204.0.0/24.
    Modify the /etc/resolv conf file on your Compute Engine instances to point to 192.168.20 88
  4. Create a private zone in Cloud DNS for 'corp altostrat.com' called corp-altostrat-com.
    Configure DNS Server Policies and create a policy with Alternate DNS servers to 192.168.20.88.
    Configure your on-premises firewall to accept traffic from 35.199.192.0/19.
    Set a custom route advertisement on the Cloud Router for 35.199.192.0/19.
