E

To configure a Cisco CallManager cluster for security, first enable services, then use the CTL Client to set cluster to mixed mode and create a signed CTL. Finally, deploy the certificates to the IP Phones and set the device security mode through the CallManager Administration.

2.

A and C

You must enable both the Cisco CAPF and CTL Provider when configuring a Cisco CallManager cluster for security.

3.

A

At a minimum, the Cisco CTL Client requires the Windows 2000 operating system, and at least one USB port, Smart Card service enabled. It does also function on the Windows XP operating system.

   
4.

A

Upgrading an LSC on a Cisco IP Phone can be done through the CallManager Administration utility without updating the CTL using the Cisco CTL Client.

5.

A and F

These answers show the valid security configuration options of the Cisco IP Phone through the CallManager Administration.

6.

C and D

When a phone configured for authentication calls a nonsecure phone, the resulting call will negotiate to the lowest-common-denominator, which is nonsecure. Likewise, when a phone configured for encryption calls a phone configured for authentication, the resulting call will negotiate to the lowest-common-denominator, which is authentication.

7.

C and D

You can generate a query using the device name through the Find and List Phones window. The certificate lifetime is not a searchable field.

8.

A and E

You can query based on both the authentication mode and device security mode from the Find and List Phones window.

9.

A

The Cisco 7920 Wireless IP Phone does not support the phone security features.

10.

B, C, and D

All of these communication types cannot be encrypted using phone security. In addition, calls streaming music on hold (MOH) cannot be secured.
