Question 52

You are designing an IP address scheme for new private Google Kubernetes Engine (GKE) clusters, Due to IP address exhaustion of the RFC 1918 address space in your enterprise, you plan to use privately used public IP space for the new dusters. You want to follow Google-recommended practices, What should you do after designing your IP scheme?

Options:

Create the minimum usable RFC 1918 primary and secondary subnet IP ranges for the clusters. Re-use the secondary address range for the pods across multiple private GKE clusters.

Create the minimum usable RFC 1918 primary and secondary subnet IP ranges for the clusters Re-use the secondary address range for the services across multiple private GKE clusters.

Create privately used public IP primary and secondary subnet ranges for the clusters. Create a private GKE cluster With the following options selected: --enab1e-ip-a1ias and --enable-private-nodes.

Answer:

Explanation:

The correct answer is D. Create privately used public IP primary and secondary subnet ranges for the clusters. Create a private GKE cluster with the following options selected: --disable-default-snat, --enable-ip-alias, and --enable-private-nodes.

This answer is based on the following facts:

Privately used public IP (PUPI) addresses are any public IP addresses not owned by Google that a customer can use privately on Google Cloud1. You can use PUPI addresses for GKE pods and services in private clusters to mitigate address exhaustion.

A private GKE cluster is a cluster that has no public IP addresses on the nodes2. You can use private clusters to isolate your workloads from the public internet and enhance security.

The --disable-default-snat option disables source network address translation (SNAT) for the cluster3. This option allows you to use PUPI addresses without conflicting with other public IP addresses on the internet.

The --enable-ip-alias option enables alias IP ranges for the cluster4. This option allows you to use separate subnet ranges for nodes, pods, and services, and to specify the size of those ranges.

The --enable-private-nodes option enables private nodes for the cluster5. This option ensures that the nodes have no public IP addresses and can only communicate with other Google Cloud resources in the same VPC network or peered networks.

The other options are not correct because:

Option A is not suitable. Creating RFC 1918 primary and secondary subnet IP ranges for the clusters does not solve the problem of address exhaustion. Re-using the secondary address range for pods across multiple private GKE clusters can cause IP conflicts and routing issues.

Option B is also not suitable. Creating RFC 1918 primary and secondary subnet IP ranges for the clusters does not solve the problem of address exhaustion. Re-using the secondary address range for services across multiple private GKE clusters can cause IP conflicts and routing issues.

Option C is not feasible. Creating privately used public IP primary and secondary subnet ranges for the clusters is a valid step, but creating a private GKE cluster with only --enable-ip-alias and --enable-private-nodes options is not enough. You also need to disable default SNAT to avoid IP conflicts with other public IP addresses on the internet.

Question 53

You have several VMs across multiple VPCs in your cloud environment that require access to internet endpoints. These VMs cannot have public IP addresses due to security policies, so you plan to use Cloud NAT to provide outbound internet access. Within your VPCs, you have several subnets in each region. You want to ensure that only specific subnets have access to the internet through Cloud NAT. You want to avoid any unintentional configuration issues caused by other administrators and align to Google-recommended practices. What should you do?

Options:

Deploy Cloud NAT in each VPC and configure a custom source range that includes the allowed subnets. Configure Cloud NAT rules to only permit the allowed subnets to egress through Cloud NAT.

Create a firewall rule in each VPC at priority 500 that targets all instances in the network and denies egress to the internet (0.0.0.0/0). Create a firewall rule at priority 300 that targets all instances in the network, has a source filter that maps to the allowed subnets, and allows egress to the internet (0.0.0.0/0). Deploy Cloud NAT and configure all primary and secondary subnet source ranges.

Create a constraints/compute.restrictCloudNATUsage organizational policy constraint. Attach the constraint to a folder that contains the associated projects. Configure the allowedValues to only contain the subnets that should have internet access. Deploy Cloud NAT and select only the allowed subnets.

Question 54

You configured Cloud VPN with dynamic routing via Border Gateway Protocol (BGP). You added a custom route to advertise a network that is reachable over the VPN tunnel. However, the on-premises clients still cannot reach the network over the VPN tunnel. You need to examine the logs in Cloud Logging to confirm that the appropriate routers are being advertised over the VPN tunnel. Which filter should you use in Cloud Logging to examine the logs?

Options:

resource.type= “gce_router”

resource.type= “gce_network_region”

resource.type= “vpn_tunnel”

resource.type= “vpn_gateway”

Are these dumps helpful?

Jeremiah Oct 27, 2024

Yes, Don’t worry!!! I'm confident you'll find them to be just as helpful as I did. Good luck with your exam!

Carson

Yeah, definitely. I would definitely recommend Cramkey Dumps to anyone who is preparing for an exam.

Rufus Aug 20, 2024

Me too. They're a lifesaver!

Lennie

I passed my exam and achieved wonderful score, I highly recommend it.

Emelia Oct 2, 2024

I think I'll give Cramkey a try next time I take a certification exam. Thanks for the recommendation!

River

Hey, I used Cramkey Dumps to prepare for my recent exam and I passed it.

Lewis Sep 11, 2024

Yeah, I used these dumps too. And I have to say, I was really impressed with the results.

Question 55

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?
