Question #11
Which two methods are recommended for managing the VMware Directory Service? (Choose two.)
- AUtilize the vmdir command.
- BManage through the vSphere Web Client.
- CManage using the VMware Directory Service.
- DUtilize the dc rep command.
Correct Answer:
AB
A) dir-cli Command Reference -
The dir-cli utility allows you to create and update solution users, create other user accounts, and manage certificates and passwords in vmdir. ( link: to see vmdir commands-- https://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.vsphere.security.doc%2FGUID-4FBEA58E-9492-409B-B584-

)
B) Directory service associated with the vsphere.local domain. This service is a multi-tenanted, multi-mastered directory service that makes an LDAP directory available on port 11711. In multisite mode, an update of VMware Directory Service content in one VMware Directory Service instance results in the automatic update of the VMware Directory Service instances associated with all other vCenter Single Sign-On nodes via Vsphere Web Client.

Question #14
An administrator would like to use the VMware Certificate Authority (VMCA) as an Intermediate Certificate Authority (CA). The first two steps performed are:
✑ Replace the Root Certificate
✑ Replace Machine Certificates (Intermediate CA)
Which two steps would need to be performed next? (Choose two.)
✑ Replace the Root Certificate
✑ Replace Machine Certificates (Intermediate CA)
Which two steps would need to be performed next? (Choose two.)
- AReplace Solution User Certificates (Intermediate CA)
- BReplace the VMware Directory Service Certificate (Intermediate CA)
- CReplace the VMware Directory Service Certificate
- DReplace Solution User Certificates
Correct Answer:
AC
Use VMCA as an Intermediate Certificate Authority
You can replace the VMCA root certificate with a third-party CA-signed certificate that includes VMCA in the certificate chain. Going forward, all certificates that
VMCA generates include the full chain. You can replace existing certificates with newly generated certificates. This approach combines the security of third-party
CA-signed certificate with the convenience of automated certificate management.
Procedure -
Replace the Root Certificate (Intermediate CA)
The first step in replacing the VMCA certificates with custom certificates is generating a CSR and adding the certificate that is returned to VMCA as a root certificate.
Replace Machine SSL Certificates (Intermediate CA)
After you have received the signed certificate from the CA and made it the VMCA root certificate, you can replace all machine SSL certificates.
Replace Solution User Certificates (Intermediate CA)
After you replace the machine SSL certificates, you can replace the solution user certificates.
Replace the VMware Directory Service Certificate
If you decide to use a new VMCA root certificate, and you unpublish the VMCA root certificate that was used when you provisioned your environment, you must replace the machine SSL certificates, solution user certificates, and certificates for some internal services.
Replace the VMware Directory Service Certificate in Mixed Mode Environments
During upgrade, your environment might temporarily include both vCenter Single Sign-On version 5.5 and vCenter Single Sign-On version 6.0, you have to perform additional steps to replace the VMware Directory Service SSL certificate if you replace the SSL certificate of the node on which the vCenter Single Sign-
On service is running.
