QUESTION 16
What is the process used to restore an entire cluster in the event of a catastrophic failure?
A. Restore the first node by doing a fresh install, restore the first node database from
DRS, and then restore the subsequent nodes from the DRS backup location.
B. Restore the first node from tape or SFTP and then restore each subsequent node.
C. Restore the first node and then perform a database push to the subsequent nodes in the
cluster.
D. Restore all the nodes in the cluster by means of a fresh install and then restore the
features and subcomponents to each server by means of DRS.
Answer: A
Explanation:
In case of a major failure or a hardware upgrade, you may need to restore all nodes in the
cluster. To restore a whole cluster, you must first restore the first node or publisher and then
restore the subsequent nodes.

QUESTION 17
Which three common characteristics are used to define the types of devices that go into a
device pool? (Choose three.)
A. calling search spaces for auto-registration
B. device type
C. location
D. geographic proximity
E. user hold MoH source
F. class of service
Answer: A,D,E
Explanation:
Device pools are user configurable sets of defaults that are assigned to devices as a single
function. The devices then inherit all the settings from the device pool that they are assigned.
This can be used to scale and simplify the distribution of CallManager groups, which are
discussed below. A device pool allows primary attributes to be assigned globally to a device. The
required components for a Device Pool are: Device Pool Name, CallManager Group, Date/Time
Group, Region, Softkey Template, SRST Reference. Some optional fields are: Calling Search
Space for Auto-Registration, Media Resource Group List, User Hold MOH Audio Source.
QUESTION 18
Please study the exhibit carefully. A call is placed from DN 5000 to DN 6999. The CSS
for the call includes only the Branch 1 partition. After the translation pattern is applied,
what are the called and calling numbers?
Exhibit:
642-445
www.actualtest.org – The Power of Knowing
A. 14085556999, 19195555000
B. 6999, 5000
C. 5556999, 9195555000
D. 6999, 19195555000
E. 14085556999, 5000
Answer: A
Cisco CallManager uses translation patterns to manipulate dialed digits before routing a call.
Translation patterns are similar to route patterns in that they use wildcards, transformations and
special characters. The translation pattern will convert / change the digits before anything else. If
digits match a translation pattern, CallManager applies any transformation. When 6999 is dialed
the translation pattern will change the calling and called digits. Thus, the calling number 5000 in
the Branch1 partition is changed to 19195555000 because it matches the Translation Pattern for
6999 in the Branch1 partition. Therefore, the called number 6999 is changed (Prefix digits are
applied and then the mask) to the called party, becomes 14085556999. After CallManager
applies the transformation mask(s), this call will make another trip through digit analysis.
QUESTION 19
Please study the exhibit carefully. PassGuide .com uses 4-digit extensions. To call between
sites, they dial the intersite access code ‘8′ followed by the 3-digit site code and 4-digit
extension of the phone they are trying to reach. Phone_A is in Partition Branch1 with a
CSS named BR1_External. If a user dials 85014532 from Phone_A, which element of the
642-445
www.actualtest.org – The Power of Knowing
route plan will be matched?
Exhibit:
A. Route Pattern 8501! in the partition gateway
B. the phone with extension 4532 in Partition Branch1
C. the phone with extension 4532 among the partition phones
D. Translation Pattern 85XX in the partition intersite
E. Route Pattern 8501.XXXX# in the partition gateway
F. Route Pattern 8501.XXXX in the partition gateway
Answer: D
QUESTION 20
Which of these is the best practice to employ when using certificates between a browser
and the Cisco Unified CallManager 5.0 server?
A. Use either SSH or CLI to view the thumbprint of the certificate and then communicate
the information to all web browser users so they already have it available when they
receive the security alert.
B. Install thumbprint readers on the devices that need to connect to the Cisco Unified
CallManager servers via HTTPS.
C. Use SSH exclusively to verify the thumbprint of the certificate and then send the
certificate to all web browser users that require access to the server.
D. Note the thumbprint of the Cisco Unified CallManager certificates after installation
and then communicate the information to all web browser users so they have it available
when they receive the security alert.
E. Accept the certificate when the security alert pop-up window appears.
Answer: D
