NO.1 A Cisco Unified Cm user is set up with one remote destination profile that has two remote
destination numbers: the
first destination number is the user's mobile phone in country A and the second is a mobile phone
located in country.
All outbound calls are centralized from the gateway at country A.
The user reports that inbound calls are properly routed to the mobile phone as long as the user is in
country A.
But inbound calls are not successfully routed to country B.
Which two options could be the cause of this? (Choose two)
A. The value of remote destination limits should be chaned to 2 instead of the default value of 4
under the end user page.
B. The enable mobile voice access option must be selected under the end user page.
C. The enable mobile connect option must be selected under the user's second remote destination
number.
D. The rerouting calling search space assigned to the user's remote destination profile must have
access to international calls.
E. The value of maximum wait time for desk pickup should be changed to 20000 instead of the
default of D, 10000, under the end user page.
Answer: C,D

NO.2 Which entity signs a Cisco IP phone LSC?
A. Cisco Certificate Authority
B. Godaddy.com Enrollment Server
C. Registration Authority
D. Manufacturer Certificate Authority
E. Certificate Authority Proxy Function
Answer: E

400-051 ミシュレーション   
Explanation:
By default, LSC certificates are not installed on Cisco IP phones. Cisco IP phones that are required to
use LSC
certificates must be provisioned to allow TLS transactions before deployment in the field. LSC
certificates can be
provisioned to the Cisco IP phones through the Certificate Authority Proxy Function (CAPF) process.
This process is
completed using TLS and USB tokens coupled with the CTL client. Moreover, the Cisco ASA Phone
Proxy feature can
serve LSC certificates to the Cisco IP phones. Cisco IP phones will only work with the Cisco ASA Phone
Proxy and will
not establish secure connectivity with the Cisco Unified Communications Manager.

NO.3 Refer to the exhibit.
The common device configuration has been assigned to an IPv4 only phone. Which statement
describes what
happens when the phone attempts to register with Cisco unified Communications manager?
A. The IP phone invokes MTP to translate from ipv4 to IPv6
B. The IP phone uses SLAAC to acquire an IPv6 address and override the limitation
C. The IP phone ignores the settings and registers with the ipv4 address
D. The IP phone displays the message 'registration rejected' because it cannot support IPv6
Answer: D

5. Refer to the exhibit.
A customer has two Cisco Unified Communication manager 9.X clusters that serve the same location.
An engineer has
attempted to set up Enhanced Location call admission control so that any call within a site between
phones on the
two clusters do not decrement the available bandwidth to and from that site. However, the real time
monitoring tool
currently shows bandwidth being used from the site to Hub_none. When a call is placed between
phones at the site,
which action must be taken to correct this situation?
A. The Hub_none location must have a link configured to the shadow location.
B. The hub_none location must have a link configuration to the phantom location.
C. The SIP trunks should be changed to use the shadow location.
D. The link between clusters must be a type of inter-cluster trunk instead of a sip trunk.
E. The device pool names must match between clusters.
F. Explanation:
Shadow is a new system location created for intercluster Enhanced Location CAC. In order to pass
location
information across clusters, the SIP ICT needs to be assigned to the system location Shadow.
The system location Shadow:
Is a valid location only for a SIP ICT. Devices other than SIP trunks assigned incorrectly to the Shadow
location are
treated as if assigned to the Hub_None location.
Cannot have a link connecting to other user defined locations, so bandwidth cannot be deducted
between the
Shadow location and other user defined locations.
Has no intra-location bandwidth capacities, so bandwidth cannot be deducted within the Shadow
location.
