Q53. Question:
Your organization has a hub and spoke architecture with VPC Network Peering, and hybrid connectivity is centralized at the hub. The Cloud Router in the hub VPC is advertising subnet routes, but the on-premises router does not appear to be receiving any subnet routes from the VPC spokes. You need to resolve this issue.
What should you do?

Q54. You are developing an HTTP API hosted on a Compute Engine virtual machine instance that must be invoked only by multiple clients within the same Virtual Private Cloud (VPC). You want clients to be able to get the IP address of the service. What should you do?

Q55. Your organization has a subset of applications in multiple regions that require internet access. You need to control internet access from applications to URLs, including hostnames and paths. The compute instances that run these applications have an associated secure tag. What should you do?

Q56. You are disabling DNSSEC for one of your Cloud DNS-managed zones. You removed the DS records from your zone file, waited for them to expire from the cache, and disabled DNSSEC for the zone. You receive reports that DNSSEC validating resolves are unable to resolve names in your zone.
What should you do?

Q57. You want to create a service in GCP using IPv6.
What should you do?

Q58. You have created an HTTP(S) load balanced service. You need to verify that your backend instances are responding properly.
How should you configure the health check?

Q59. You are planning a large application deployment in Google Cloud that includes on-premises connectivity. The application requires direct connectivity between workloads in all regions and on-premises locations without address translation, but all RFC 1918 ranges are already in use in the on-premises locations. What should you do?

Q60. You have the following firewall ruleset applied to all instances in your Virtual Private Cloud (VPC):

You need to update the firewall rule to add the following rule to the ruleset:

You are using a new user account. You must assign the appropriate identity and Access Management (IAM) user roles to this new user account before updating the firewall rule. The new user account must be able to apply the update and view firewall logs. What should you do?

Q61. Your organization requires that metrics from all applications be retained for 5 years for future analysis in possible legal proceedings. Which approach should you use?

Q62. Your company just completed the acquisition of Altostrat (a current GCP customer). Each company has a separate organization in GCP and has implemented a custom DNS solution.
Each organization will retain its current domain and host names until after a full transition and architectural review is done in one year.
These are the assumptions for both GCP environments.
– Each organization has enabled full connectivity between all of its
projects by using Shared VPC.
– Both organizations strictly use the 10.0.0.0/8 address space for
their instances, except for bastion hosts (for accessing the instances) and load balancers for serving web traffic.
– There are no prefix overlaps between the two organizations.
– Both organizations already have firewall rules that allow all inbound and outbound traffic from the 10.0.0.0/8 address space.
– Neither organization has Interconnects to their on-premises
environment.
You want to integrate networking and DNS infrastructure of both organizations as quickly as possible and with minimal downtime.
Which two steps should you take? (Choose two.)

Q63. There are two established Partner Interconnect connections between your on-premises network and Google Cloud. The VPC that hosts the Partner Interconnect connections is named “vpc-a” and contains three VPC subnets across three regions, Compute Engine instances, and a GKE cluster. Your on-premises users would like to resolve records hosted in a Cloud DNS private zone following Google-recommended practices. You need to implement a solution that allows your on-premises users to resolve records that are hosted in Google Cloud. What should you do?

Q64. You just finished your company’s migration to Google Cloud and configured an architecture with 3 Virtual Private Cloud (VPC) networks: one for Sales, one for Finance, and one for Engineering.
Every VPC contains over 100 Compute Engine instances, and now developers using instances in the Sales VPC and the Finance VPC require private connectivity between each other. You need to allow communication between Sales and Finance without compromising performance or security. What should you do?

Q65. You need to define an address plan for a future new GKE cluster in your VPC. This will be a VPC-native cluster, and the default Pod IP range allocation will be used. You must pre-provision all the needed VPC subnets and their respective IP address ranges before cluster creation. The cluster will initially have a single node, but it will be scaled to a maximum of three nodes if necessary. You want to allocate the minimum number of Pod IP addresses.
Which subnet mask should you use for the Pod IP address range?

Q66. 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?

Q67. You have an application that is running in a managed instance group. Your development team has released an updated instance template which contains a new feature which was not heavily tested. You want to minimize impact to users if there is a bug in the new template.
How should you update your instances?

Q68. You recently deployed Cloud VPN to connect your on-premises data center to Google Cloud. You need to monitor the usage of this VPN and set up alerts in case traffic exceeds the maximum allowed. You need to be able to quickly decide whether to add extra links or move to a Dedicated Interconnect. What should you do?

Q69. You are configuring the firewall endpoints as part of the Cloud Next Generation Firewall (Cloud NGFW) intrusion prevention service in Google Cloud. You have configured a threat prevention security profile, and you now need to create an endpoint for traffic inspection. What should you do?

Q70. You are deploying your infrastructure in the us-central1 region. Your on-premises data center is located in New York City, and the Google Cloud region closest to New York City is us-east4. Your Cloud Interconnect is located in Ashburn, Virginia (VA), United States. You need to use Cloud Interconnect to connect your application infrastructure with backend systems in your data center location. You do not expect the application bandwidth to exceed 500 Mbps. You want to minimize latency and cost. What should you do?
