Britta, a system administrator, is managing a website that is running on an IIS web server. Recently, the website was redesigned, and some portions of the website were deleted. Search engines carry links to these deleted portions for specific searches. Britta wants to ensure that when users click on links to deleted portions of the website, they're redirected to a section of the website. Which of the following IIS configuration features should Britta use?

Error Pages Error Pages specifies webpages that are shown when a specific error occurs on the Web server (e.g., 404 File Not Found for an invalid webpage name).

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?

The List of Windows container images will be displayed. If LCOW was enabled, this command would display only the Linux container images. because you diabled LCOW, the Widnows container images will be displayed. Linux containier images will not be avaliable until you enable LCOW again.

Container images that are based on Nano Server must be run as Hyper-V containers.

True Hyper-V can be used to provide each container with a separate copy of the kernel for greater stability, performance, and security. Container images that are based on Nano Server must be run as Hyper-V containers.

You download mulitple container images from DOCKER HUB and create containers using the docker run command. After a few days, you notice that the list of containers that you have rune is quite large. Which of the folowing command can you use to shoren this list?

Docker container prune

Ezra wants to install Docker on a Windows Server 2019 server. He has two options to download and install the Docker Enterprise Edition—either Microsoft or Docker. He chooses to download the package using the DockerProvider Windows PowerShell module. Which of the following justifies Ezra's choice?

Ezra intends to run Linux containers on the server.

Block storage can easily be shared by several different Web apps, virtual machines, or containers.

False Block Storage is normally associated with a single Web app, virtual machine or container only. object storage caneasly be shared by several differnt web apps, vitual machine or containers.

Skyfelt Graphics is a company that does not own any of the hardware or operating systems on which it creates and runs its Web app containers. These components are owned, maintained, and operated by a cloud provider. Which of the following cloud delivery models is Skyfelt using?

Platform as a Service This scenario exemplifies Platform as a Service. PaaS allows you to run Web app containers in the cloud.

Alya runs the following command in Windows PowerShell: docker run -d -p --name cont1 kerinapp. What does the -d option do in this scenario?

The -d option of the docker run command in the previous example detaches the container from your Windows PowerShell session and keeps it running in the background until you stop it using the docker stop command. For example, running the docker stop cust2 command will stop executing the cust2 container and release its resources to the underlying operating system; this could be performed automatically when customer 2 logs out of the organization's website.

Maqsud installs IIS on a Windows Server 2019 server. To allows users to connect to Default Web Site using HTTPS, he installs an HTTPS encryption certificate on the Web server. Next, he configures Default Web Site to respond to HTTPS requests. However, when users connect to the website using HTTPS, they receive a security warning. Which of the following is most likely causing this issue?

The FQDN in the HTTPS certificate does not match the Web server FQDN. The most likely cause for the issue is that the FQDN in the HTTPS certificate does not match the Web server FQDN. To ensure that clients do not receive a security warning, the Web server FQDN must match the FQDN listed in the HTTPS certificate.

Viola, a system administrator, installs IIS on a Web server and creates two websites. She installs the necessary HTTPS encryption certificate on the server and proceeds to bind the HTTPS protocol to the first website using default settings. This binding is successful. Next, she proceeds to bind the HTTPS protocol to the second website. Which of the following is most likely to cause an issue when binding the HTTPS protocol to the second website?

The first website is using port 443, so the second website cannot use the same port. Port 443 is used by default for HTTPS requests. When binding the HTTPS protocol to the first website using default settings, port 443 was most likely used. To avoid a conflict, Viola should choose another port or explore other alternatives.

Theodore installs a Fedora Linux distribution on a Windows Server 2019 server. He initially uses the sudo command to perform system administration on the Linux system. Later, he opens a new command prompt and runs some more administrative commands. Which of the following must be true if Theodore did not use the sudo command during the second round of administrative changes?

Theodore used the sudo passwd root command. Theodore most likely used the sudo passwd root command to assign a password to the root user using the sudo passwd root command. Once a password is assigned to the root user, you can run the su (substitute user) command to open a Linux command prompt as the root user to run administrative commands without having to prefix them with the sudo command.

Ralph uses Docker EE to run his web apps in containers he builds a new app to process financial information provided by customers and file taxes. Owing to the sesitive nature of this infomation, Ralph wants to use secure containers that would also provide grater stability and performace. What should Ralph do?

you can use Hyper-V to provide each container with a separate copy of the kernel for greater stability, performance, and security. To run a Hyper-V container, you add the --isolation=hyperv option to the docker run command.

Runako wants to build a social networking website and host it using a PaaS provider. The social networking website will have users posting and sharing large quantities of media such as videos and images. He is currently evaluating the storage options that the app will need. Which of the following storage options should Runako use and why?

Object storage, because it allows a Web app to directly store objects Runako should use object storage. Object storage allows Web apps to directly store objects, such as pictures, files, and video, using an HTTP request that is sent to an object storage service. Web apps that need to store and share thousands of pictures, files, and video typically use object storage.

Kenshin builds a collaboration tool using ASP.NET that allows users to discuss and share files with each other. The files are stored in a Web server on a platform managed by a cloud service provider. Which of the following IIS role services is integral to the file-sharing feature in Kenshin's Web app?

FTP Server The FTP Server role service allows users and ASP.NET Web apps to transfer files to and from the Web server using the FTP protocol.

To run a Windows Web app in a public cloud using SaaS, you will need to create, configure, and maintain the associated Windows Server 2019 virtual machine on the public cloud provider's hypervisor.

False

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?

She should install a small footprint virtual machine. Because public cloud providers charge based on resource usage, Lin should install a small footprint virtual machine that contains Server Core, IIS, and the necessary Web app frameworks to save cost.

LCOW requires that each Linux container run on a separate Linux kernel and achieves this by automatically running each Linux container as a Hyper-V container.

TRUE LCOW requires that each Linux container run on a separate Linux kernel. To achieve this, LCOW automatically runs each Linux container as a Hyper-V container to ensure that each Linux container receives a separate Linux kernel provided by LinuxKit.

TravelBugz is a website that reviews accommodations and holiday destinations. Users of the website can post their own reviews. Users can use the TravelBugz app too instead of the website if they want to. The app and website both directly access the Web app running on the cloud to store and retrieve data. Which of the following is true of this scenario?

The TravelBugz app communicates with the Web app using the TCP/IP protocol. Client programs and mobile apps can also be used as the front end for Web apps, either by connecting to a website using the HTTP or HTTPS protocol or by communicating directly to a Web app on a cloud server using a different TCP/IP protocol.

Describe the need for and process of changing the default folder for downloaded container images.

you should ensure that container images are stored on a volume that contains enough space for the number and size of container images you wish to use. To modify the default folder used to store container images, you can create the C:\ProgramData\docker\config\daemon.json text file and edit the contents to specify the appropriate path. For example, to store downloaded container images under D:\ProgramData\docker, you can add the following contents to C:\ProgramData\docker\config\daemon.json: { "graph": "D:\\ProgramData\\docker" } After modifying the C:\ProgramData\docker\config\daemon.json file, you must restart the Docker daemon for the changes to take effect. To do this, you can use the Restart-Service Docker command in Windows PowerShell

Why does IIS contain an FTP server service? What is the alternative option for Web app developers who do not want to use this service?

if the Web server is located in a cloud environment across the Internet, File Transfer Protocol (FTP) is often used to transfer website and Web app content. As a result, IIS contains an FTP server service that you can optionally install to provide FTP access on your Web server. Alternatively, Web app developers can use Web Distributed Authoring and Versioning (WebDAV) to upload and modify website content (but not Web app content). WebDAV uses the standard HTTP and HTTPS protocols to transfer information.
