NEW QUESTION # 31
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?
- A. Connect all the spokes to the hub With Cloud VPN. Use a third-party network appliance as a default gateway to prevent connectivity between the spokes
- B. Connect all the spokes to the hub with VPC Network Peering.
- C. Connect all the spokes to the hub with Cloud VPN.
- D. Connect all the spokes to the hub with VPC Network Peering. Use a third-party network appliance as a default gateway to prevent connectivity between the spokes.
Answer: D
Explanation:
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.

NEW QUESTION # 32
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?
- A. 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. - B. 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.
- C. 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 a custom source range that includes the allowed subnets. - D. 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.
Answer: B
Explanation:
Explanation: Using an organizational policy with the restrictCloudNATUsage constraint allows you to limit Cloud NAT usage to specific subnets, ensuring that only the necessary subnets can access the internet. This method aligns with Google-recommended practices for controlling Cloud NAT configurations across multiple VPCs and regions.

NEW QUESTION # 34
You have the networking configuration shown in the diagram. A pair of redundant Dedicated Interconnect connections (int-Igal and int-Iga2) terminate on the same Cloud Router The Interconnect connections terminate on two separate on-premises routers. You are advertising the same prefixes from the Border Gateway Protocol (BGP) sessions associated with the Dedicated Interconnect connections. You need to configure one connection as Active for both ingress and egress traffic. If the active Interconnect connection fails, you want the passive Interconnect connection to automatically begin routing all traffic Which two actions should you take to meet this requirement? (Choose Two)
- A. Configure the advertised route priority as 200 for the BGP session associated With the passive Interconnect connection.
- B. Advertise a lower MED on the passive Interconnect connection from the on-premises router
- C. Configure the advertised route priority as 200 for the BGP session associated Wlth the active Interconnect connection.
- D. Configure the advertised route priority > 10,200 on the active Interconnect connection.
- E. Advertise a lower MED on the active Interconnect connection from the on-premises router
Answer: C,E
Explanation:
This answer meets the requirement of configuring one connection as Active for both ingress and egress traffic, and enabling automatic failover to the passive connection in case of failure. The reason is:
The advertised route priority is a value that Cloud Router uses to set the route priority when advertising routes to your on-premises router. The lower the value, the higher the priority1. By setting the advertised route priority as 200 for the active connection, you ensure that it has a higher priority than the passive connection, which has the default value of 1001. This way, your on-premises router will prefer the routes from the active connection over the passive one for ingress traffic.
The MED (Multi-Exit Discriminator) is a value that your on-premises router uses to indicate its preference for receiving traffic from Cloud Router. The lower the value, the higher the preference2. By advertising a lower MED on the active connection from your on-premises router, you ensure that Cloud Router will prefer sending traffic to the active connection over the passive one for egress traffic.
If the active connection fails, Cloud Router will stop receiving routes from it and will start using the routes from the passive connection for egress traffic. Similarly, your on-premises router will stop receiving routes with priority 200 from the active connection and will start using the routes with priority 100 from the passive connection for ingress traffic. This achieves automatic failover without any manual intervention.
Option A is incorrect because setting the advertised route priority > 10,200 on the active connection would deprioritize it globally in your VPC network, which is not what you want1. Option B is incorrect because advertising a lower MED on the passive connection would make Cloud Router prefer sending traffic to it over the active one, which is not what you want2. Option D is incorrect because setting the advertised route priority as 200 for both connections would make them equally preferred by your on-premises router, which is not what you want1.

NEW QUESTION # 35
Your organization has resources in two different VPCs, each in different Google Cloud projects, and requires connectivity between the resources in the two VPCs. You have already determined that there is no IP address overlap; however, one VPC uses privately used public IP (PUPI) ranges. You would like to enable connectivity between these resources by using a lower cost and higher performance method. What should you do?
- A. Create a VPC Network Peering connection between the two VPCs that allows the export and import of subnet routes with public IP addresses. Create the necessary ingress VPC firewall rules that target the specific resources by using network tags as the source filter.
- B. Create a VPC Network Peering connection between the two VPCs that allows the export and import of subnet routes with public IP addresses. Create the necessary ingress VPC firewall rules that target the specific resources by using IP ranges as the source filter.
- C. Create a VPC Network Peering connection between the two VPCs that allows the export and import of custom routes for public IP addresses. Create the necessary ingress VPC firewall rules that target the specific resources by using service accounts as the source filter.
- D. Create an HA VPN between the two VPCs that includes the PUPI ranges in the custom route advertisements of the Cloud Router. Create the necessary ingress VPC firewall rules that target the specific resources by using IP ranges as the source filter.
Answer: B
Explanation:
Explanation: VPC Network Peering is the most cost-effective and high-performance method for connecting two VPCs. Since one VPC uses privately used public IP (PUPI) ranges, you need to configure peering to allow the export and import of subnet routes with public IP addresses. Firewall rules can be used to control traffic between the resources.

NEW QUESTION # 40
Your company's logo is published as an image file across multiple websites that are hosted by your company You have implemented Cloud CDN, however, you want to improve the performance of the cache hit ratio associated with this image file. What should you do?
- A. Configure the default time to live (TTL) as O for the image file.
- B. Configure versioned IJRLs for each domain to serve users the *mage file before the cache entry expires
- C. Configure Cloud Storage as a custom origin backend to host the image file, and select multi-region as the location type
- D. Configure custom cache keys for the backend service that holds the image file, and clear the Host and Protocol checkboxes-
Answer: D
Explanation:
This answer meets the requirement of improving the performance of the cache hit ratio associated with the image file. The reason is:
* Custom cache keys allow you to control which parts of the request URL are used to build the cache key. The cache key is a unique identifier that Cloud CDN uses to store and retrieve cached content1.
* By default, Cloud CDN uses the complete request URL, including the protocol (http or https) and the host (the domain name), to build the cache key. This means that if the same image file is requested from different domains or protocols, Cloud CDN will cache multiple copies of it, which reduces the cache hit ratio1.
* By clearing the Host and Protocol checkboxes, you can tell Cloud CDN to ignore these parts of the request URL when building the cache key. This way, Cloud CDN will cache only one copy of the image file, regardless of which domain or protocol it is requested from, which improves the cache hit ratio1.
Option B is incorrect because configuring Cloud Storage as a custom origin backend does not affect the cache hit ratio. It only affects how Cloud CDN retrieves the content from the origin if it is not cached. Option C is incorrect because configuring versioned URLs for each domain does not improve the cache hit ratio. It actually worsens it, because it creates more variations of the request URL that Cloud CDN has to cache separately. Option D is incorrect because configuring the default TTL as 0 for the image file means that Cloud CDN will not cache it at all, which defeats the purpose of using Cloud CDN.

(You need to migrate multiple PostgreSQL databases from your on-premises data center to Google Cloud.
You want to significantly improve the performance of your databases while minimizing changes to your data schema and application code. You expect to exceed 150 TB of data per geographical region. You want to follow Google-recommended practices and minimize your operational costs. What should you do?)
- A. Migrate your data to Firebase.
- B. Migrate your data to Bigtable.
- C. Migrate your data to AlloyDB.
- D. Migrate your data to Spanner.
Answer: A,B,C
Explanation:
Let's analyze each option based on the requirements: PostgreSQL compatibility, significant performance improvement, minimal schema/code changes, handling large data volumes, Google-recommended practices, and cost minimization:
A: Migrate your data to AlloyDB: AlloyDB for PostgreSQL is a fully managed, PostgreSQL-compatible database service that offers significant performance improvements over standard PostgreSQL due to its architectural optimizations. It is designed to handle large data volumes and minimizes the need for schema and application code changes as it's wire-compatible with PostgreSQL. This aligns well with the requirements for performance improvement, minimal changes, large data, and being a Google-recommended option for PostgreSQL workloads.
B: Migrate your data to Spanner: Spanner is a globally distributed, horizontally scalable database with strong consistency. While it offers excellent scalability and performance, it's not directly PostgreSQL-compatible.
Migrating to Spanner would likely require significant schema and application code changes due to differences in data modeling and SQL dialect.
C: Migrate your data to Firebase: Firebase is a suite of mobile and web development tools, with its primary database offering being Firestore (a NoSQL document database) and Realtime Database. These are not PostgreSQL-compatible and would require substantial changes to the data model and application code.
D: Migrate your data to Bigtable: Bigtable is a highly scalable NoSQL wide-column store. It's not compatible with PostgreSQL and requires a completely different data model and application logic.
Therefore, AlloyDB is the most suitable option as it provides PostgreSQL compatibility for minimal migration effort, significant performance improvements, scalability for large data volumes, and is a recommended Google Cloud database service for PostgreSQL workloads.
