An existing vCloud Director environment that has been operational for a year is suddenly
inaccessible via its web site. The error: Could not verify this certificate for unknown reasons
appears. Which course of action should an administrator take to address this problem?
A.
 Issue the command service vmware-vcd stop. Install a new certificate using the 
command keytool – keystore certificates.ks – storetype JCEKS –storepass passwd –genkey 
–keyalg RSA – alias http. Issue the command service vmware-vcd start.
B.
 Issue the command service vmware-vcd stop. Obtain or generate a new security 
certificate. Install the certificate using /opt/vmware/cloud-director/bin/configure. Start the 
vCD service.
C.
 Access the vCloud Director administration web site through the internal network address. 
From within the Security option under the Administration tab, generate a new, self-signed 
certificate.
D.
 Generate a new certificate using keytool from within the vCD VM. Change the 
permissions on the resulting certificates.ks file to be readable by vcloud.vcloud. Issue the 
command service vmware-vcd restart.
