All Obstacles During 350-801 Exam Preparation with 350-801 Real Test Questions [Q138-Q161]

NO.138 An engineer must configure switch port 5/1 to send CDP packets to configure an attached Cisco IP phone to trust tagged traffic on it’s access port. Which command is required to complete the configuration?

NO.139 When configuring Cisco Unified Communications Manager, which configuration enables phones to automatically register to a Cisco Unified Communications publisher when the connection to the subscriber is lost?

NO.140 Refer to the exhibit. A customer submits this output, captured on a Cisco IOS router. Assuming that an MGCP gateway is configured with a ISDN BRI interface, which BRI changes resolve the issue?

NO.141


Refer to the exhibit. What is the reason for this call failure?

NO.142 A remote office has a less-than-optimal WAN connection and experiences packet loss, delay and jitter. Which VoIP codec is used in this situation?

NO.143 When a call Is delivered to a gateway, the calling and called party number must be adapted to the PSTN service requirements of the trunk group. If a call is destined locally, the + sign and the explicit country code must be replaced with a national prefix. For the same city or region, the local area code must be replaced by a local prefix as applicable. Assuming that a Cisco UCM has a SIP trunk to a New York gateway (area code
917). which two combinations of solutions localize the calling and called party for a New York phone user?
(Choose two.)

NO.144 Callers from a branch report getting busy tones intermittetly when trying to reach colleagues in other office branches during peak hours. An engineer collects Cisco CallManager service traes to examine the situation. The traces show:

What should be fixed to resolve the issue?

NO.145 Refer the exhibit.

Given this “debug isdn q921” output, what is the problem with the PRI?

NO.146 A network administrator with ID392116981 has determined that a WAN link between two Cisco UCM clusters supports only 1 Mbps of bandwidth for voice traffic.
How many calls does this link support if G.711 as the audio codec is used?

NO.147 An engineer with ID0123456789 is designing a new dial plan for a customer that has offices in several countries on four continents around the world. This client also wants to integrate with a Microsoft Lync backend. Which dial plan type does the engineer recommend?

NO.148 What is the cisco UCM service parameter default value for DSCP for Telepresence calls ?

NO.149 An engineer configures local roule group names to simplify a dial plan. Where does the engineer set the route groups according to the local route group names that are configured?

NO.150 What happens to voice packets from a Cisco 8845 IP phone in the QoS trust boundary?

NO.151

Refer to the exhibit. An engineer is troubleshooting why PSTN phones are not receiving the caller’s name when called from a remote Cisco UCM site. An ISDN PRI connection is being used to reach the PSTN What must the administrator select to resolve the issue?

NO.152 An administrator uses the Cisco Unified Real-Time Monitoring Tool to investigate recent calls on a Cisco UCM cluster. The SIP trace for an on-net. direct-media call shows two 180 Ringing and two 11 BYE messages. Why are there multiples of each message type in the trace?

NO.153 Endpoint A is attempting to call endpoint B.
Endpoint A only supports G.711ulaw with a packetization rate of 20 ms, and endpoint B supports packetization rate of 30 ms for G.711ulaw. Which two media are resources are allocated to normalize packetization rates through transrating?

NO.154 Due to provider requirements, outgoing calls from the Enterprise to the PSTN must start with channel 1.
Which ISDN command changes the channel selection on IOS to meet this requirement?

NO.155 SIP proxies have operations defined in RFC 3261 and supporting extensions. Though no lETF RFC completely defines how SBCs must function. SBCs evolved over the years.
Which two operations demonstrate the high-level differences between SBCs and SIP proxies? (Choose two.)

NO.156 A collaboration engineer inherits the responsibilities of another engineer. The previous engineer implemented a SIP integration between Cisco Unity Connection and Cisco UCM. Users can leave messages, but the Message Waiting Indicator is unconfigured. Which two actions must the engineer perform to enable MWI? (Choose two.)

NO.157 Refer to the exhibit.

Refer to the exhibit. When a UC Administrator is troubleshooting DTMF negotiated by this SIP INVITE, which two messages are examined next to further troubleshoot the issue? (Choose two.)

NO.158 An engineer with ID012345678 must build an international dial plan in Cisco UCM. Which action is taken when building a variable-length route pattern?

NO.159 Due to service provider restriction, Cisco Unified Communications Manager cannot send video in the SDP. Which two options on Cisco Unified CM are configured to suppress video in the SDP is outgoing invites? (Choose two.)

NO.160 How does Cisco define jitter?

NO.161 An engineer must help a customer’s administrator to set QoS options for the cluster. What are two QoS settings on the Cisco UCM server? (Choose two.)
