NEW QUESTION # 109
Your multi-region VPC has had a long-standing HA VPN configured in "region 1" connected to your corporate network. You are planning to add two 10 Gbps Dedicated Interconnect connections and VLAN attachments in "region 2" to connect to the same corporate network. You need to plan for connectivity between your VPC and corporate network to ensure that traffic uses the Dedicated Interconnect connections as the primary path and the HA VPN as the secondary path. What should you do?

• A. Enable regional dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in "region 1" to use a base priority value of 20000. Configure BGP associated with the VLAN attachments to use a base priority of 100. Configure your on-premises routers to use similar multi-exit discriminator (MED) values.
• B. Enable regional dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in "region 1" to use a base priority value of 100. Configure BGP associated with the VLAN attachments to use a base priority of 20000. Configure your on-premises routers to use similar multi-exit discriminator (MED) values.
• C. Enable global dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in "region 1" to use a base priority value of 20000. Configure BGP associated with the VLAN attachments to use a base priority of 100. Configure your on-premises routers to use similar multi-exit discriminator (MED) values.
• D. Enable global dynamic routing mode on the VPC. Configure BGP associated with the HA VPN in "region 1" to use a base priority value of 100. Configure BGP associated with the VLAN attachments to use a base priority of 20000. Configure your on-premises routers to use similar multi-exit discriminator (MED) values.

Answer: D

Explanation:
For the Dedicated Interconnect to be the primary connection over the HA VPN, you should:
Enable global dynamic routing mode to allow the VPC to distribute routes dynamically across regions.
Set the BGP priority for the VLAN attachments associated with the Dedicated Interconnect to a lower base priority (e.g., 100) than the HA VPN's priority (e.g., 20000) to ensure it is preferred.
Setting up global dynamic routing with adjusted BGP priorities on both Interconnect and VPN will allow dynamic routing of traffic based on set preferences and path attributes, such as MED and priority levels. This setup ensures the Dedicated Interconnect, with a lower priority value, becomes the primary path for traffic, while the HA VPN, with a higher priority, serves as a backup.

NEW QUESTION # 126
(You are developing an internet of things (IoT) application that captures sensor data from multiple devices that have already been set up. You need to identify the global data storage product your company should use to store this data. You must ensure that the storage solution you choose meets your requirements of sub- millisecond latency. What should you do?)

• A. Store the IoT data in Cloud Storage. Implement caching by using Cloud CDN.
• B. Store the IoT data in Bigtable.
• C. Capture IoT data in BigQuery datasets.
• D. Store the IoT data in Spanner. Use caches to speed up the process and avoid latencies.

Answer: B

Explanation:
Comprehensive and Detailed In Depth Explanation:
Let's evaluate each option based on the requirement of sub-millisecond latency for globally stored IoT data:
A). Spanner with Caching: While Spanner offers strong consistency and global scalability, the base latency might not consistently be sub-millisecond for all read/write operations globally. Introducing caching adds complexity and doesn't guarantee sub-millisecond latency for all initial reads or cache misses.
B). Bigtable: Bigtable is a highly scalable NoSQL database service designed for low-latency, high-throughput workloads. It excels at storing and retrieving large volumes of time-series data, which is typical for IoT sensor data. Its architecture is optimized for single-key lookups and scans, providing consistent sub-millisecond latency, making it a strong candidate for this use case.
C). BigQuery: BigQuery is a fully managed, serverless data warehouse designed for analytical queries on large datasets. While it's excellent for analyzing IoT data in batch, it's not optimized for the low-latency, high- throughput ingestion and retrieval required for real-time IoT applications with sub-millisecond latency needs.
D). Cloud Storage with Cloud CDN: Cloud Storage is object storage and is not designed for low-latency transactional workloads. Cloud CDN is a content delivery network that caches content closer to users for faster delivery, but it's not suitable for the primary storage of rapidly incoming IoT sensor data requiring sub- millisecond write latency.
Google Cloud Documentation References:
Cloud Bigtable Overview: https://cloud.google.com/bigtable/docs/overview - This document highlights Bigtable's suitability for low-latency and high-throughput applications, including IoT. It mentions its ability to handle massive amounts of data with consistent performance.
Spanner Overview: https://cloud.google.com/spanner/docs/overview - While Spanner offers low latency, Bigtable is generally preferred for extremely high-throughput, low-latency use cases like raw sensor data ingestion due to its optimized architecture for such workloads.
BigQuery Overview: https://cloud.google.com/bigquery/docs/introduction - This emphasizes BigQuery's analytical capabilities rather than low-latency operational workloads.
Cloud Storage Overview: https://cloud.google.com/storage/docs/overview - This describes Cloud Storage as object storage, not ideal for sub-millisecond latency reads and writes required for real-time IoT data.

NEW QUESTION # 127
Question:
Your organization has an on-premises data center. You need to provide connectivity from the on-premises data center to Google Cloud. Bandwidth must be at least 1 Gbps, and the traffic must not traverse the internet.
What should you do?

• A. Configure Dedicated Interconnect by creating a VLAN attachment, activate the connection, and submit the pairing key to your service provider.
• B. Configure HA VPN by using high availability gateways and tunnels.
• C. Configure Cross-Cloud Interconnect by creating a VLAN attachment, activate the connection, and then submit the pairing key to your service provider.
• D. Configure Partner Interconnect by creating a VLAN attachment, submit the pairing key to your service provider, and activate the connection.

Answer: D

Explanation:
For private connectivity with at least 1 Gbps bandwidth and without using the public internet, Partner Interconnect is the suitable choice if you do not require the 10 Gbps minimum of Dedicated Interconnect.
With Partner Interconnect, you create a VLAN attachment and work with a service provider that facilitates the connection between your on-premises network and Google Cloud. This solution supports connections as low as 50 Mbps and up to 10 Gbps.
