LEARNING INTERVENING GOOGLE CLOUD- VIRTUAL NETWORKS
Learning Objectives:
- Enumerating how it becomes possible to interact with Google Cloud.
- Use the Google Cloud Console and Cloud Shell.
Create Cloud Storage buckets. - Deploy solutions through Google Cloud Marketplace.
INTERACTING WITH GOOGLE CLOUD
1. Which of the following does not allow you to interact with Google Cloud?
- Google Cloud Console
- REST-based API
- Cloud Explorer (CORRECT)
- Cloud Shell
Correct: Correct! There are four primary ways of interacting with Google Cloud, which are: the Cloud Console, Cloud Shell and the Cloud SDK, APIs, and the Cloud Mobile App. However, Cloud Explorer isn’t really a Google Cloud tool.
2. What is the difference between the Google Cloud Console and Cloud Shell?
- Cloud Shell is a command-line tool, while the Cloud Console is a graphical user interface (CORRECT)
- The Cloud Console is a command-line tool, while Cloud Shell is a graphical user interface
- Cloud Shell is a locally installed tool, while the Cloud Console is a temporary virtual machine.
- There is no difference as these tools are 100% identical.
Correct: The Cloud Console is a graphical interface, while Cloud Shell is a command-line tool. Both enable interaction with Google Cloud. While the Cloud Console may do tasks the Cloud Shell cannot do, and vice versa.
VIRTUAL NETWORKS
1. In Google Cloud, what is the minimum number of IP addresses that a VM instance needs?
- One: Only an internal IP address (CORRECT)
- Two: One internal and one external IP address
- Three: One internal, one external and one alias IP address
Correct: Each virtual machine in Google Cloud requires an internal IP address. An external address is optional. In other words, a VM instance requires only one IP address: the internal IP.
2. What are the three types of networks offered the Google Cloud?
- Zonal, regional, and global
- Gigabit network, 10 gigabit network, and 100 gigabit network
- Default network, auto network, and custom network. (CORRECT)
- IPv4 unicast network, IPv4 multicast network, IPv6 network
Correct: The three network types offered by Google Cloud are: In Google Cloud, three types of networks are available- default, auto, and custom. A default-based project starts with the default network. The auto-type network applies default subnet IP ranges but has the different network name same as the default. A custom-based network, on the other hand, will give an option to set your own IP ranges for subnets.
3. What is one benefit of applying firewall rules by tag rather than by address?
- Tags help organizations track firewall billing.
- Tags in network traffic help with network sniffing.
- Tags on firewall rules control which ephemeral IP addresses VMs will receive.
- When a VM is created with a matching tag, the firewall rules apply irrespective of the IP address it is assigned. (CORRECT)
Correct: An ephemeral external IP address will be allocated to the newly created VM from a pool of addresses. It will be unpredictable as to which specific address will be assigned, and therefore no rule can be written that will match the particular IP address of a VM until it has been assigned. Tags allow a symbolic assignment that cuts across the order of IP addresses, thus laying the foundation for firewall rules that are easier, more general, and less maintenance-intensive.
