You are a network administrator of an Active Directory domain named contoso.com.
You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the Web Server
(IIS) server role installed.
Server1 will host a web site at URL https: //secure.contoso.com. The application pool identity
account of the web site will be set to a domain user account named AppPool1.
You need to identify the setspn.exe command that you must run to configure the appropriate
Service Principal Name (SPN) for the web site.
What should you run?

Explanation:
Note:
* -s <SPN>
Adds the specified SPN for the computer, after verifying that no duplicates exist.
Usage: setspn –s SPN accountname
For example, to register SPN “http/daserver” for computer “daserver1”:
setspn -S http/daserver daserver1

Definition of an SPN
An SPN is the name by which a client uniquely identifies an instance of a service. If you install
multiple instances of a service on computers throughout a forest, each service instance must have
its own SPN. A particular service instance can have multiple SPNs if there are multiple names that
clients might use for authentication. For example, an SPN always includes the name of the host
computer on which the service instance is running. Therefore, a service instance might register an
SPN for each name or alias of its host.
Adding SPNs
To add an SPN, use the setspn -s service/namehostname command at a command prompt, where
service/name is the SPN that you want to add and hostname is the actual host name of the
computer object that you want to update. For example, if there is an Active Directory domain
controller with the host name server1.contoso.com that requires an SPN for the Lightweight
Directory Access Protocol (LDAP), type setspn -s ldap/server1.contoso.com server1, and then press
ENTER to add the SPN.
The HTTP service class
The HTTP service class differs from the HTTP protocol. Both the HTTP protocol and the HTTPS
protocol use the HTTP service class. The service class is the string that identifies the general class of
service.
For example, the command may resemble the following command:
setspn –S HTTP/iis6server1. mydomain.com mydomain\appPool1
