Question 1

Lin chooses to run a Windows Web app in a public cloud environment using IaaS. She wants to optimize the cost of running the application on the cloud. Which of the following options should Lin choose?
A) She should install the Datacenter Edition of Windows Server 2019.
B) She should start with maximum recommended configuration.
C) She should purchase more block storage than object storage.
D) She should install a small footprint virtual machine.

Accepted Answer

Installing a small footprint virtual machine will help optimize the cost of running the application on the cloud because it will use less resources, resulting in lower costs. Choosing the Datacenter Edition or maximum recommended configuration will likely increase costs, and purchasing more block storage than object storage could be irrelevant to optimizing the cost of running the application.

Question 4

You set up a Windows Server 2019 system and install the Docker EE package. The server also has IIS installed. Next, you enable LCOW and run a Linux container. Which of the following is true of this scenario?
A) The Docker EE package was installed using DockerMsftProvider.
B) The Web server is running Windows containers.
C) The Linux kernel provided by Docker runs on the Hyper-V hypervisor.
D) The Linux container runs on a Docker component called Docker Hub.

Accepted Answer

Enabling LCOW means that Docker will use a Linux kernel provided by Docker instead of running Windows container. This Linux kernel runs on the Hyper-V hypervisor, which means that the Linux container will run on the Hyper-V hypervisor as well. Therefore, choice C is correct as it describes the mechanism of how LCOW works. Choices A, B, and D are incorrect as they are either irrelevant to the scenario or inaccurate.

Question 5

You enable LCOW on a Windows Server 2019 system that already has IIS installed. The server is also used to run Windows containers. Next, you download and run some Linux containers. You disable LCOW and run the docker images command. What will be the result in this scenario?
A) The list of Windows container images will be displayed.
B) The list of Linux container images will be displayed.
C) All container images on the system will be displayed.
D) None of the container images on the system will be displayed.

Accepted Answer

When LCOW (Linux Containers on Windows) is disabled, Docker on Windows will only manage and display Windows container images. Linux container images will not be shown or managed in this state.

Question 12

Emory install the WSL feature on a Web server. Next, she installs an Ubuntu Linux distribution and creates a new Linux user account, EmoryJ. She logs into the Ubuntu system using this user account. Which of the following is true of this scenario?
A) Emory can use the EmoryJ user account to run administrative commands as the root user.
B) By default, EmoryJ is assigned the Administrator or super user of the Linux system.
C) Emory can use the password assigned to EmoryJ to log into the Linux system as the super user.
D) By default, each administrative command should be prefixed with the su command.

Accepted Answer

In Linux systems, including those installed via WSL (Windows Subsystem for Linux), a regular user can execute commands with root (superuser) privileges by prefixing the command with "sudo" and entering their own password when prompted. This allows for administrative tasks to be performed without logging in as the root user directly. The "su" command is used to switch users, including switching to the root user, but administrative commands are more commonly prefixed with "sudo" for security and convenience. The statement in option A is correct because it reflects this capability, assuming the user has been granted sudo privileges, which is common for the first user created on a Linux system.
