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: That’s correct! There are four ways you can interact with Google Cloud: There’s the Cloud Console, Cloud Shell and the Cloud SDK, the APIs, and the Cloud Mobile App. The Cloud Explorer is not 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 user interface and Cloud Shell is a command-line tool. Both tools allow you to interact with Google Cloud. Even though the Cloud Console can do things Cloud Shell can’t do and vice-versa, don’t think of them as alternatives, but think of them as one extremely flexible and powerful interface.
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: In Google Cloud, each virtual machine needs to have an internal IP address. The external IP address is optional; therefore, a VM instance only needs one IP address.
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: default, auto and custom. Each project starts with a default network. The auto-type network uses the same subnet IP ranges as the default-type, with a network name other than default. A custom-type allows you to specify the IP ranges of 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: When a VM is created the ephemeral external IP address is assigned from a pool. There is no way to predict which address will be assigned, so there is no way to write a rule that will match that VM’s IP address before it is assigned. Tags allow a symbolic assignment that does not depend on order in the IP addresses. It makes for simpler, more general, and easier to maintain, firewall rules.
