  F. From the Recovery Disk Menu options, select [Q] to quit recovery program and reboot the virtual machine.
  G. Log in to the DRS and perform a Cisco Unified CM restore from the backup.
  B. Create a new virtual machine with the Cisco OVA template and do a fresh install with the Cisco Unified CM bootable Iso.
  D. Take a backup of the system with Disaster Recovery System.

• Question 472:

  Which statement about the effective path in the Enhanced Location Call Admission Control mechanism on Cisco Unified Communications Manager is true?

  A. It is a sequence of links and intermediate locations that connect a pair of locations.
  B. It is used to define the bandwidth that is available between locations.
  C. Only one effective path is used between two locations.
  D. There could be multiple effective paths between a pair of locations.
  E. It logically represents the WAN link.
  C. Only one effective path is used between two locations.

  ---

  The effective path is the path used by Unified CM for the bandwidth calculations, and it has the least cumulative weight of all possible paths. Weights are used on links to provide a "cost" for the "effective path" and are pertinent only when there is more than one path between any two locations.

  You can join two or more Connection servers or clusters (up to a maximum of ten) to form a well-connected network, referred to as a Connection site. The servers that are joined to the site are referred to as locations. (When a Connection cluster is configured, the cluster counts as one location in the site.) Within a site, each location uses SMTP to exchange directory synchronization information and messages directly with every other location. Each location is said to be linked to every other location in the site via an intrasite link. When you link two Cisco Unity Connection sites with an intersite link, the gateway for each site is responsible for collecting information about all changes to the local site directory, and for polling the remote site gateway periodically to obtain information about updates to the remote site directory. The gateways use the HTTP or HTTPS protocol to exchange directory synchronization updates.

• Question 478:

  B. Remove the Unity Connection primary server from the HTTPS network on each node in the cluster.
  C. Remove all servers in the Unity Connection cluster from the other clusters in the HTTPS network.
  D. Update any downstream Unity Connection locations so that they link with a Unity Connection that will continue to have access to the hub location.
  E. Remove the existing link to the remaining Unity Connection locations subtree and add new links to locations that will remain connected to the hub.
  F. Update any remote call handlers and interview handlers that targeted the users on the location as well as any location downstream from the commissioned site to be removed.
