Review Questions

You can find the solutions to these questions in Appendix A, "Answers to Review Questions."

1.

Which four of the following are IP telephony deployment models that are supported by Cisco? (Choose four.)

  1. a single site with one call-processing agent
  2. multiple sites with centralized call processing
  3. multiple sites each with its own call-processing agent
  4. a single cluster with distributed call processing
  5. multiple clusters with no call-processing agent
2.

A 1:1 redundancy design offers _________.

  1. increased redundancy; however, the increased server cost is often prohibitive
  2. some redundancy; however, a server reboot is required after an upgrade
  3. maximum uptime; however, no more than a 20-ms round-trip delay can exist between servers
  4. high availability; however, you might overwhelm the backup servers
3.

A single cluster that spans multiple sites can have which two benefits compared to a branch office in a multisite WAN with a centralized call-processing deployment? (Choose two.)

  1. completely self-contained individual sites
  2. WAN bandwidth cost savings
  3. a common dial plan across all sites
  4. more IP Phone features during failover
  5. scalability to hundreds of sites
4.

Which two of the following enable the cluster to achieve redundancy? (Choose two.)

  1. Windows clustering
  2. database replication
  3. at least two servers
  4. directory access
5.

When configuring the SQL database relationship between Cisco CallManager servers, how many publisher servers should you configure for the cluster?

  1. It depends on the server platform; you should have one publisher for each group of phones followed by a backup.
  2. You should have only one publisher server for the entire cluster.
  3. You should have at least two publisher servers to provide database redundancy.
  4. You must configure a publisher for each subscriber you install.
6.

What is the maximum number of SQL subscribers that can exist in a Cisco CallManager cluster?

  1. 3
  2. 5
  3. 8
  4. 9
  5. 12
7.

To support a centralized, multisite Cisco CallManager design, what feature should be employed at the remote offices?

  1. QoS
  2. SRST
  3. Classification
  4. SQL database replication
8.

When using a multisite, single-cluster Cisco CallManager design, it is not necessary to employ SRST features to support the IP Phones in the case of Cisco CallManager failure. (True/False)

9.

When designing a distributed, multicluster Cisco CallManager design, what pieces of equipment might be necessary to ensure the IP telephony network maintains a consistent and centralized dial plan? (Choose two.)

  1. H.323 gatekeeper
  2. H.323 gateways
  3. SIP proxy server
  4. Cisco CallManager
10.

What is the maximum Cisco CallManager cluster size Cisco will support using Cisco CallManager 4.x?

  1. 7500 IP Phones
  2. 10,000 IP Phones
  3. 12,000 IP Phones
  4. 15,000 IP Phones
  5. 30,000 IP Phones
