Google Cloud Computing Foundations: Networking & Security in Google Cloud (8)

1. It helps the network

Objectives

Networking in the cloud

A Virtual Private Cloud (VPC) is composed of subnetworks, or subnets, and each subnet must be configured with a private IP CIDR address.

CIDR stands for Classless Inter-domain Routing.

Virtual Private Cloud (VPC) networks allow you to maintain isolated environments within a larger cloud structure, giving you granular control over data protection, network access, and application security.

Congratulations! You passed this assessment.

1.What is used to forward traffic from one instance to another within the same network, across subnetworks, or even between Google Cloud zones, and doesn’t require an external IP address?

• (x) Routing table
• Firewall
• Subnet
• Load balancer

Good job! That’s the correct answer.

2.What term describes where the Google network is connected to the rest of the internet?

• Zone
• IP address
• Region
• (x) Point of presence (PoP)

Good job! That’s the correct answer.

3.Which option would you choose if you required cross-regional load balancing for a web application?

• (x) HTTP(S) Load Balancing
• SSL Proxy Load Balancing
• Internal HTTP(S) Load Balancing
• TCP Proxy Load Balancing

Good job! That’s the correct answer.

4.Select the true statement.

• VPCs are regional and subnets are zonal.
• VPCs are regional. Subnets are not used in Google Cloud.
• VPCs are global and subnets are regional.
• (x) Both VPCs and subnets are global.

Unlucky! That’s not the correct answer.

5.Which connectivity solution provides a direct connection to Google?

• Partner Interconnect
• Direct Peering
• Carrier Peering
• (x) Dedicated Interconnect

Good job! That’s the correct answer.

2. Keep an eye on things

Cloud Monitoring provides visibility into the performance, uptime, and overall health of cloud-powered applications. Cloud Monitoring collects metrics, events, and metadata from Google Cloud, Amazon Web Services, hosted uptime probes, application instrumentation, and a variety of common application components including Cassandra, Nginx, Apache Web Server, Elasticsearch, and many others. Cloud Monitoring ingests that data and generates insights via dashboards, charts, and alerts. Cloud Monitoring alerting helps you collaborate by integrating with Slack, PagerDuty, HipChat, Campfire, and more.

the Monitoring and Logging agents

Agents collect data and then send or stream info to Cloud Monitoring in the Cloud Console.

The Cloud Monitoring agent is a collected-based daemon that gathers system and application metrics from virtual machine instances and sends them to Monitoring. By default, the Monitoring agent collects disk, CPU, network, and process metrics. Configuring the Monitoring agent allows third-party applications to get the full list of agent metrics. On the Google Cloud, Operations website, see Cloud Monitoring Documentation for more information.
