Question 28

Your organization recently created a sandbox environment for a new cloud deployment. To have parity with the production environment, a pair of Compute Engine instances with multiple network interfaces (NICs) were deployed. These Compute Engine instances have a NIC in the Untrusted VPC (10.0.0.0/23) and a NIC in the Trusted VPC (10.128.0.0/9). A HA VPN tunnel has been established to the on-premises environment from the Untrusted VPC. Through this pair of VPN tunnels, the on-premises environment receives the route advertisements for the Untrusted and Trusted VPCs. In return, the on-premises environment advertises a number of CIDR ranges to the Untrusted VPC. However, when you tried to access one of the test services from the on-premises environment to the Trusted VPC, you received no response. You need to configure a highly available solution to enable the on-premises users to connect to the services in the Trusted VPC. What should you do?

Options:

Add both multi-NIC VMs to a new unmanaged instance group, named nva-uig.

Create an internal passthrough Network Load Balancer in the Untrusted VPC, named ilb-untrusted, with the nva-uig unmanaged instance group designated as the backend.

Create a custom static route in the Untrusted VPC for destination 10.123.0.0/9 and the next hop ilb-untrusted.

Add both multi-NIC VMs to a new unmanaged instance group, named nva-uig.

Create two custom static routes in the Untrusted VPC for destination 10.128.0.0/9 and set each of the VMs’ NIC as the next hop.

Create two custom static routes in the Trusted VPC for destination 10.0.0.0/23 and set each of the VMs' NIC as the next hop.

Question 29

You have deployed an HTTP(s) load balancer, but health checks to port 80 on the Compute Engine virtual machine instance are failing, and no traffic is sent to your instances. You want to resolve the problem. Which commands should you run?

Options:

gcloud compute instances add-access-config instance-1

gcloud compute firewall-rules create allow-lb --network load-balancer --allow tcp --destination-ranges 130.211.0.0/22,35.191.0.0/16 --direction EGRESS

gcloud compute firewall-rules create allow-lb --network load-balancer --allow tcp --source-ranges 130.211.0.0/22,35.191.0.0/16 --direction INGRESS

gcloud compute health-checks update http health-check --unhealthy-threshold 10

Question 30

(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?)

Options:

Migrate your data to AlloyDB.

Migrate your data to Spanner.

Migrate your data to Firebase.

Migrate your data to Bigtable.

Answer:

Explanation:

Comprehensive and Detailed In Depth 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.

Question 31

You need to enable Private Google Access for use by some subnets within your Virtual Private Cloud (VPC). Your security team set up the VPC to send all internet-bound traffic back to the on- premises data center for inspection before egressing to the internet, and is also implementing VPC Service Controls in the environment for API-level security control. You have already enabled the subnets for Private Google Access. What configuration changes should you make to enable Private Google Access while adhering to your security team’s requirements?

Options:

Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Google's restricted API address range.

Create a custom route that points Google's restricted API address range to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to restricted.googleapis.com, with an A record pointing to Google's restricted API address range.

Change the custom route that points the default route (0/0) to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record painting to Google's private AP address range.

Change the custom route that points the default route (0/0) to the default internet gateway as the next hop.

Create a private DNS zone with a CNAME record for *.googleapis.com to private.googleapis.com, with an A record pointing to Google's private API address range.

Create a custom route that points Google's private API address range to the default internet gateway as the next hop.
