You have an Exchange Server 2013 organization named Contoso. The organization contains a server
named Server1 that has Exchange Server 2013 installed. Server1 has the Mailbox server role and the
Client Access server role installed. Server1 has a Send connector for a partner company. The Send
connector is configured for Domain Security with a domain named adatum.com. The only certificate
installed on Server1 expires. You discover that all email messages sent to adatum.com remain in the
queue on Server1. On Server1, you install a new certificate from a trusted third-party. You need to
ensure that the email messages are delivered to adatum.com. What should you do?

A.
Assign the new certificate to the IIS service.

B.
Send the new certificate to the administrator at adatum.com.

C.
Assign the new certificate to the SMTP service.

D.
Create a new send connector that contains an address space to adatum.com.

Explanation:
Note:
* The Enable-ExchangeCertificate cmdlet enables certificates when it updates the metadata that is
stored with the certificate. To enable an existing certificate to work with different services, run the
Enable-ExchangeCertificate command and specify the services that you want to enable. You can
rerun this cmdlet if you want to add new services that use the certificate.
When you enable a certificate for the Simple Mail Transfer Protocol (SMTP) service and the
certificate contains a FQDN that matches the FQDN of the local computer, the certificate may be
published to the Active Directory directory service.
