Lpi LPIC-3 Exam 305: Virtualization and Containerization 認定 305-300 試験問題 (Q11-Q16):

質問 # 11
A clone of a previously used virtual machine should be created. All VM specific information, such as user accounts, shell histories and SSH host keys should be removed from the cloned disk image. Which of the following tools can perform these tasks?

正解：E


質問 # 12
After creating a new Docker network using the following command:
docker network create --driver bridge isolated_nw
which parameter must be added todocker createin order to attach a container to the network?

正解：A

解説：
Explanation
To attach a container to a network when creating it, the --network flag must be used with the name of the network as the argument. The --network flag specifies the network mode for the container. By default, the network mode is bridge, which means the container is connected to the default bridge network. However, if a custom network is created, such as isolated_nw in this case, the container must be explicitly attached to it using the --network flag. For example, to create a container named web1 and attach it to the isolated_nw network, the command would be:
docker create --name web1 --network isolated_nw nginx
The other options are not valid parameters for docker create. The --eth0, --ethernet, and --attach flags do not exist. The --alias flag is used to specify an additional network alias for the container on a user-defined network, but it does not attach the container to the network. References:
* docker network create | Docker Documentation1
* docker create | Docker Documentation
* Networking overview | Docker Docs2


質問 # 13
What is the primary purpose of Vagrant's "Vagrantfile" configuration file?

正解：C


質問 # 14
What is the default provider of Vagrant?

正解：C

解説：
Explanation
Vagrant is a tool that allows users to create and configure lightweight, reproducible, and portable development environments. Vagrant supports multiple providers, which are the backends that Vagrant uses to create and manage the virtual machines. By default, VirtualBox is the default provider for Vagrant. VirtualBox is still the most accessible platform to use Vagrant: it is free, cross-platform, and has been supported by Vagrant for years. With VirtualBox as the default provider, it provides the lowest friction for new users to get started with Vagrant. However, users can also use other providers, such as VMware, Hyper-V, Docker, or LXC, depending on their preferences and needs. To use another provider, users must install it as a Vagrant plugin and specify it when running Vagrant commands. Users can also change the default provider by setting the VAGRANT_DEFAULT_PROVIDER environmental variable. References:

質問 # 15
