2021 Mar 300-075 brain dumps
Q41. Refer to the exhibit.
The HQ site uses area code 650. The BR1 site uses area code 408. The long distance national code for PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9, followed by 1, and then the 10-digit number.
Both sites use MGCP gateways. AAR must use globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are localized at the egress gateway as shown in the exhibit.
Which partition should be configured in the AAR CSS applied at the phones?
A. PSTN partition
B. LD partition
C. The HQ AAR CSS must include a partition assigned to route pattern 91408XXXXXXX. The BR1 AAR CSS must include a partition assigned to route pattern 91650XXXXXXX.
D. AAR CSS must contain translation pattern 9.1[2-9]XX[2-9]XXXXXX for each site that must be globalized. Otherwise the called numbers will not be localized at the egress gateway.
Q42. How does the system intelligently shift call processing upon restoration of WAN connectivity?
A. automatically back to the primary Cisco Unified Communications Manager cluster
B. manually back to the primary Cisco Unified Communications Manager cluster
C. automatically back to the secondary Cisco Unified Communications Manager cluster
D. manually back to the secondary Cisco Unified Communications Manager cluster
Q43. You recently implemented call redundancy at a new remote site, and users report that calls are dropped when the remote site supposedly is in SRST. Which two actions must you take to troubleshoot the problem? (Choose two.)
A. Confirm that SRST is configured on the voice gateway.
B. Confirm that the site has an SRST reference that is correctly associated with the Cisco Unified Communications Manager group.
C. Confirm that a calling search space is assigned to the voice gateway in Cisco Unified Communications Manager.
D. Confirm that the site devices are associated with a Cisco Unified Communications Manager group and that four Cisco Unified Communications Manager servers are available.
E. Check the Region settings in Cisco Unified Communications Manager.
F. Restart Cisco Unified Communications Manager services to confirm that the server is working correctly.
Q44. Refer to the exhibit.
Locations-based CAC has been configured between HQ and the BR site. Assume that the priority queue has been provisioned correctly for three G.729 calls. What happens when
the fourth call is placed from HO to BR?
A. The call will get through via the WAN. But it will experience poor audio quality.
B. The call will fail.
C. The call will be queued until one of the existing calls drop.
D. The call will get through without any issues.
Q45. Which statement about the host portion format in Cisco Unified Communications Manager URI dialing is false?
A. The host portion cannot start or end with a hyphen.
B. The host portion is not case sensitive.
C. The host portion accepts characters a-z, A-Z, 0-9, hyphens, and periods.
D. The host portion can have two periods in a row.

Q46. Refer to the exhibit.
HQ_MRGL is assigned to the HQ IP phones. BR_MRGL is assigned to the BR IP phones. The remote site BR IP phones support only the G.711 codec. Where should the transcoder reside?
A. The transcoder should reside at the HQ site and assigned to HQ_MRG.
B. The transcoder should reside at the BR site and assigned to BR_MRG.
C. The transcoder should be assigned to its own MRG, which should then be assigned to the default device pool.
D. A transcoder is not needed. The HQ phones will automatically change over to the G.711 codec.
Q47. While configuring Call Survivability in Cisco Unified Communications Manager, what step is mandatory to reach remote sites while in SRST mode?
A. Enable Cisco Remote Site Reachability.
B. Configure CFUR.
C. Enable the SRST checkbox in the MGCP gateway.
D. Configure the H.323 gateway for SRST in Cisco Unified Communications Manager.
E. Enable the Failover Service parameter.
Incorrect Answer: A, C, D, E Call Forward Unregistered (CFUR) functionality provides the automated rerouting of calls through the PSTN when an endpoint is considered unregistered due to a remote WAN link failure Link: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/models.html
Q48. When an incoming PSTN call arrives at an H.323 gateway, how does the calling number get normalized to a global E.164 number with + prefix in Cisco Unified Communications Manager?
A. Normalization is done using translation patterns.
B. Normalization is done using route patterns.
C. Normalization is done using the gateway incoming called party prefixes based on number type.
D. Normalization is done using the gateway incoming calling party prefixes based on number type.
E. Normalization is achieved by local route group that is assigned to the H.323 gateway.
Q49. What is the default DSCP/PHB for TelePresence video conferencing packets in Cisco Unified Communications Manager?
Q50. Which two statements about remote survivability are true? (Choose two.)
A. SRST supports more Cisco IP Phones than Cisco Unified Communications Manager Express in SRST mode.
B. Cisco Unified Communications Manager Express in SRST mode supports more Cisco IP Phones than SRST.
C. MGCP fallback is required for ISDN call preservation.
D. MGCP fallback functions with SRST.
