As part of a multisite Single Sign-On (SSO) deployment what two steps are required to ensure that a change to one Single Sign-On instance is propagated to the other instances? (Choose two.)
A. Schedule a Replication Task on the primary instance
B. Select the first instance during the installation of subsequent instances
C. During the installation of each instance choose Linked-Mode
D. Enable Synchronize to Active Directory on each instance
Correct Answer: BC
Explanation/Reference:
Explanation:
When deploying the servers in a multisite Single Sign-On (SSO) deployment, we need to select the Linked-Mode option.
Multiple Single Sign-On instances in different locations: his mode is designed for vCenter Server deployments with multiple physical locations. Multisite deployment is required when a single administrator needs to administer vCenter Server instances that are deployed on geographically dispersed sites in Linked Mode.
Each site is represented by one vCenter Single Sign-On instance, with one vCenter Single Sign-On server, or a high-availability cluster. The vCenter Single Sign-On site entry point is the machine that other sites communicate with. This is the only machine that needs to be visible from the other sites. In a clustered deployment, the entry point of the site is the machine where the load balancer is installed.
Note:
This deployment mode is required if you have geographically dispersed vCenter Servers in Linked Mode. You might also consider this mode in the following cases:
If multiple vCenter Servers require the ability to communicate with each other.
If you require one vCenter Single Sign-On server security domain for your organization.
The first instance installed will be the primary server. During the installation of subsequent (secondary) instances, we need to select the first (primary) instance.
Incorrect Answers:
A: In previous versions of vSphere, this step would be required. However, the replication of changes on the primary instance to other instances is automatic with vSphere 5.5. Therefore this step is not required so this answer is incorrect.
D: In an Active Directory domain, this step is not required. The only requirement is that the servers in the multisite deployment are members of the same Active Directory domain. Therefore, this answer is incorrect.
