質問 # 47
You are a network administrator at your company planning a migration to Google Cloud and you need to finish the migration as quickly as possible, To ease the transition, you decided to use the same architecture as your on-premises network' a hub-and-spoke model. Your on-premises architecture consists of over 50 spokes.
Each spoke does not have connectivity to the other spokes, and all traffic IS sent through the hub for security reasons. You need to ensure that the Google Cloud architecture matches your on-premises architecture. You want to implement a solution that minimizes management overhead and cost, and uses default networking quotas and limits. What should you do?
正解：D
解説：
The correct answer is D because it meets the following requirements:
* It matches the hub-and-spoke model of the on-premises network, where each spoke is a separate VPC network that is connected to a central hub VPC network.
* It minimizes management overhead and cost, because VPC Network Peering is a simple and low-cost way to connect VPC networks without using any external IP addresses or VPN gateways1.
* It uses default networking quotas and limits, because VPC Network Peering does not consume any quota or limit for VPN tunnels, external IP addresses, or forwarding rules2.
* It prevents connectivity between the spokes, because VPC Network Peering is non-transitive by default, meaning that a spoke can only communicate with the hub, not with other spokes1. To enforce this restriction, a third-party network appliance can be used as a default gateway in each spoke VPC network, which can filter out any traffic destined for other spokes3.
Option A is incorrect because it does not minimize cost, as Cloud VPN charges for egress traffic and requires external IP addresses for the VPN gateways4. Option B is incorrect because it does not prevent connectivity between the spokes, as VPC Network Peering allows direct communication between peered VPC networks by default1. Option C is incorrect because it does not minimize cost or use default quotas and limits, for the same reasons as option A.

質問 # 48
Your company is working with a partner to provide a solution for a customer. Both your company and the partner organization are using GCP. There are applications in the partner's network that need access to some resources in your company's VPC. There is no CIDR overlap between the VPCs.
Which two solutions can you implement to achieve the desired results without compromising the security? (Choose two.)
正解：B、C
解説：
Google Cloud VPC Network Peering allows internal IP address connectivity across two Virtual Private Cloud (VPC) networks regardless of whether they belong to the same project or the same organization.
質問 # 49
You are deploying an application that runs on Compute Engine instances. You need to determine how to expose your application to a new customer You must ensure that your application meets the following requirements
* Maps multiple existing reserved external IP addresses to the Instance
* Processes IP Encapsulating Security Payload (ESP) traffic
What should you do?
正解：B
解説：
The correct answer is C. Configure a target instance, and create a protocol forwarding rule for each external IP address to be mapped to the instance.
This answer is based on the following facts:
A target instance is a Compute Engine instance that handles traffic from one or more forwarding rules1. You can use target instances to forward traffic to a single VM instance from one or more external IP addresses2.
A protocol forwarding rule specifies the IP protocol and port range for the traffic that you want to forward3. You can use protocol forwarding rules to forward traffic of any IP protocol, including ESP4.
The other options are not correct because:
Option A is not possible. You cannot create protocol forwarding rules for a target pool. A target pool is a group of instances that receives traffic from a network load balancer5.
Option B is not suitable. You do not need to create an external network load balancer for each external IP address. An external network load balancer distributes traffic among multiple backend instances based on the destination IP address and port. You can use a single load balancer with multiple forwarding rules to map multiple external IP addresses to the same backend service.
Option D is not feasible. You cannot add multiple external IP addresses to a single network interface of a Compute Engine instance. Each network interface can have only one external IP address that is either ephemeral or static. You can use alias IP ranges to assign multiple internal IP addresses to a single network interface, but not external IP addresses.
質問 # 50
Your organization wants to deploy HA VPN over Cloud Interconnect to ensure encryption-in- transit over the Cloud Interconnect connections. You have created a Cloud Router and two VLAN attachments. The BGP sessions are operational. You need to complete the deployment of the HA VPN over Cloud Interconnect. What should you do?
正解：D
解説：
HA VPN over Cloud Interconnect requires two separate Cloud Router instances - one dedicated to the Interconnect VLAN attachments and a second one for the HA VPN tier. To finish your deployment, you must:
1. Create an HA VPN gateway and associate its two interfaces with your encrypted VLAN attachments.
2. Provision a new Cloud Router for the HA VPN tier (you cannot reuse the Interconnect-tier router).
3. Configure the peer VPN gateway resources and HA VPN tunnels against that new router.
This separation ensures the Interconnect BGP session remains distinct from your HA VPN BGP session, as documented by Google's HA VPN over Cloud Interconnect architecture.
質問 # 51
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 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?
正解：C
解説：
Explanation: The correct configuration requires setting the Peer ASN as 64517 (as this is the ASN of the third-party customer). The local and peer BGP IP addresses should also be set correctly based on the provided information, and MD5 authentication should be disabled. The route priority should be set to 100 to reflect standard behavior.
