Home pages are the landing pages that users see when they access SAP Build Work Zone. They can display information that is relevant to the company, an area, or a workspace. There are some aspects that need to be considered when working with home pages, such as:
Home pages have a dedicated content area that can be customized using the page builder. The content area is where you can add rows, columns, widgets, cards, and other elements to create a layout for your home page. The content area is different from the feed area, which shows the latest updates and notifications from the company, area, or workspace1.
The home page editor has different layout options compared to workspaces. The home page editor allows you to create a persistent navigation bar with links to other pages or external URLs. You can also add a header image and a title to your home page. The workspace editor does not have these options, but it allows you to add tabs to organize your content into different pages2.
Some aspects that are not true about home pages are:
External home pages can only be configured in the external user Company Admin Area. This is not true, because external home pages can also be configured in the external user Area Admin Area. External home pages are the home pages that are shown to external users, who are users that do not belong to your company but have access to some of your content. You can create external home pages for the company level and for each area level. To do so, you need to switch to the external user Company Admin Area or the external user Area Admin Area, which are separate from the internal user admin areas3.
Company area home pages are always shown to all users. This is not true, because company area home pages are only shown to the users who belong to that specific area. Company area home pages are the home pages that are designed for a specific area or department within the company. They display information that is relevant to that area and also include the area feed. Content is shared by everyone in the specific area. To create a company area home page, you need to be an administrator that is assigned to that area1.

To access the administration console of SAP Build Work Zone, you need to have the administrator permission in Digital Workspace Service. This permission is granted by the company administrator or the area administrator of the site that you want to access. Without this permission, you will not see the Administration Console option under your avatar in the User Actions menu. The other options (B, C, and D) are not related to the administration console access, but to the SAP BTP account and subaccount level permissions that are required for setting up SAP Build Work Zone.

A shadow user is a user that is automatically created on the SAP BTP subaccount level when a user logs in to SAP Build Work Zone for the first time1. The shadow user is assigned the SAP BTP subaccount viewer role collection, which is required for accessing SAP Build Work Zone2. If a shadow user does not exist on the SAP BTP subaccount level, the user cannot login to SAP Build Work Zone. The other options are not valid reasons for the login issue, because:
SAP BTP global account viewer role collection is not required for accessing SAP Build Work Zone2.
Active default identity provider on SAP BTP subaccount level is a prerequisite for enabling SAP Build Work Zone3, but not a reason for the login issue.
SAP BTP subaccount viewer role collection is automatically assigned to the shadow user2, so it is not missing unless the shadow user does not exist. Reference: 1: Shadow Users 2: SAP BTP Subaccount Viewer Role Collection 3: Enable SAP Build Work Zone

The feed widget setting that is used on the home page level to show all public feed updates is Global. The feed widget is a type of widget that embeds a feed in an external web page. The feed widget builder allows users to create and customize feed widgets using various settings, such as the feed source, the feed type, the feed layout, and the feed filter. The feed source setting determines which feed is displayed in the widget. There are four options for the feed source setting: Public, Global, Home, and Company. The Public option displays the public feed of the site, which includes all public updates from all workspaces and members. The Global option displays the global feed of the site, which includes all public and private updates from all workspaces and members that the user has access to. The Home option displays the home feed of the user, which includes all updates that are relevant to the user, such as updates from their workspaces, followed members, and @mentions. The Company option displays the company feed of the user, which includes all updates from the user's company, such as updates from their colleagues, managers, and subordinates. The feed widget setting that is used on the home page level to show all public feed updates is Global, because it shows all the updates that the user can see on the site, regardless of their workspace or member affiliation. The other options are either too restrictive (Home and Company) or too broad (Public) for the home page level. Reference:

About Widgets

The URL pattern for the Digital Workplace Service component is composed of the following elements:
The subaccount subdomain, which is the name of the subaccount that hosts the service instance.
The work zone type, which is either workzone for SAP Build Work Zone, standard edition, or workzoneadv for SAP Build Work Zone, advanced edition.
The DWS datacenter, which is the region where the service instance is deployed, such as eu10, us10, or ap10.
The suffix cfapps.hana.ondemand.com, which is the domain name for Cloud Foundry applications.
Therefore, the correct URL pattern is https://<subaccount subdomain><work zone type>.cfapps.<DWS datacenter>.hana.ondemand.com.
The other options are incorrect because they do not follow the correct order or format of the URL elements.
