A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients. A DHCP server automatically sends the required network parameters for clients to properly communicate on the network. Without it, the network administrator has to manually set up every client that joins the network, which can be cumbersome, especially in large networks. DHCP servers usually assign each client with a unique dynamic IP address, which changes when the client’s lease for that IP address has expired. When to use a router/switch as your DHCP Server
The Benefits of a dedicated DHCP Server
Organizations that are beginning to implement IPv6 should migrate DHCP for IPv4 scope off the routers/switches and put them on a robust DHCP server infrastructure. This change will also mean that your organization would want to have DHCP operate the same for both protocols. Enterprise organizations will want to take advantage of the centralized dual-protocol DHCP server to provide IPv4 and IPv6 addresses to client devices.

One question he asks is – what kind of trust relationship is automatically created when you create a new AD DS tree in an existing AD DS forest? What would be your response?A. A Parent and Child trust Correct Answer: C Explanation When a new AD DS tree is created in an existing AD DS forest, it automatically creates a new tree-root trust. Option A is incorrect. When a new AD DS domain is added to an existing AD DS tree, it creates new parent and child trusts.

From the below list of attributes or objects, choose the ones that are synchronized from an on-premises AD DS environment to Azure AD DS or Azure AD.A. Group Policies Correct Answer: E Explanation The following attributes or objects are not synchronized from an on-premises AD DS environment to Azure AD DS or Azure AD:
Option A is incorrect. Not only group policies, but all the given attributes or objects are not synchronized. Reference: To know more about synchronization, please visit the below-given link: https://docs.microsoft.com/en-us/azure/active-directory-domain-services/synchronization Domain : Deploy and Manage Active Directory Domain Services (AD DS) in On-premises and Cloud EnvironmentsQ6 : There are two sites Manchester and Sydney in Whizlabs.com. A single GPO (called Manchester settings) is linked to Manchester and another (Sydney settings) is linked to Sydney. Additionally, there are 2 GPOs linked to the Whizlabs.com domain: The Default Domain GPO (which is Enforced) and a further policy: Whizlabs Folder Redirection (which has a link order value of 2). The Sales OU has a linked GPO called Sales Desktop settings. A user in the Sales department based in Sydney, whose user account and computer account reside in the Sales OU, is facing issues with settings on their computer. Being the administrator, you decide to investigate. You suspect that there are conflicting settings in the several GPOs that apply to the users and their computers. Which of the following GPOs settings take precedence?A. Sydney setting GPO Correct Answer: B Explanation The Default Domain Policy GPO is associated with the domain, and it applies to Authenticated Users. Because of not having any WMI filters, it affects all the computers and users in the domain. In the above case, Default Domain GPO takes precedence because it is Enforced. Option A is incorrect. Sydney setting GPO won’t take precedence as it is likely to be superseded by more specific GPOs on the domain and OU.

Which of the following parameters would you use to specify the name of the availability set where it should be created?A. -AvailabilitySetName Correct Answer: A Explanation Virtual machines must be created within the availability set to ensure they are correctly distributed across the hardware. An existing virtual machine can’t be added to an availability set after it has been created. When you create a virtual machine with New-AzVM cmdlet, you should use the -AvailabilitySetName parameter for specifying the name of the availability set. Option A is correct. -AvailabilitySetName is the right parameter to specify the name of the availability set.

Which of the following statements is false about a primary or a secondary zone?A. It is possible to create, delete or edit resource records in a primary zone. Correct Answer: B Explanation While creating a zone on a DNS server, you need to identify whether it is a primary zone or a secondary zone. If you want to create, delete or edit the resource records, you need to use the primary zone. As a secondary zone is a read-only copy of a primary zone, resource records can’t be managed in a secondary zone. Option A is incorrect. It is true that you can create, delete or edit resource records in a primary zone.
