Cisco 350-801 Online Questions & Answers

• Question 531:

  How many DNS SRV entries can be defined in the SIP trunk destination address field in Cisco Unified Communications Manager?

  A. 1
  B. 8
  C. 16
  D. 4
  A. 1

  ---

  Explanation

  1 SRV record is allowed. Multiple FQDNs are allowed. CUCM, within SIP Trunk Configuration, literally grays out the capability to add more than one record if the checkbox to use a SRV record is set - At least on 12.x, which is what this exam is based off of.

• Question 532:

  Which command enables SIP OAuth mode on a Cisco UCM publisher node?

  A. utils sip-OAuth-mode enable
  B. utils sipOAuth-mode enable
  C. utils sip-OAuth-mode activate
  D. utils sipOAuth-mode activate
  B. utils sipOAuth-mode enable

• Question 533:

  An engineer is troubleshooting a phone that powers on, receives an IP address, but cannot download its configuration file.

  Which DHCP option should be verified first for a Cisco UCM deployment?

  A. Option 66
  B. Option 150
  C. Option 3
  D. Option 6
  B. Option 150

  ---

  Explanation

  Option 150 is correct because Cisco collaboration endpoints commonly use it to learn the TFTP server address for configuration file download. Option 3 supplies the default gateway, Option 6 supplies DNS servers, and Option 66 is not the expected primary answer for Cisco UCM phone configuration in this context.

• Question 534:

  What is required for Cisco UCM to accept SIP calls with a URI in the format of "sip [email protected]"?

  A. Define Cluster Fully Qualified Domain Name under Servers in Cisco UCM.
  B. Change the Destination Address to a Fully Qualified Domain Name on the SIP trunk.
  C. Set the SIPS URI Handling to True in CallManager Service Parameters.
  D. Define Cluster Fully Qualified Domain Name in Enterprise Parameters.
  D. Define Cluster Fully Qualified Domain Name in Enterprise Parameters.

• Question 535:

  In a company meeting employees join virtually and listen. However, the SpeakerTrack device that is connected to a collaboration endpoint that follows the speaker suddenly stops working.

  What is the cause of this issue?

  A. The microphone panel is obstructed to detect the voice of the speaker
  B. The SpeakerTrack device is in standby mode
  C. The left camera or right camera is disconnected
  D. The SpeakerTrack is running a firmware version that is not compatible with the codec
  A. The microphone panel is obstructed to detect the voice of the speaker

• Question 536:

  A SIP call is established successfully, but in-band keypad events are not recognized by the far end.

  Which DTMF relay method is explicitly covered for troubleshooting in the exam topics?

  A. SIP INFO only
  B. H.245 alphanumeric
  C. RFC 2833/4733
  D. CAS signaling
  C. RFC 2833/4733

  ---

  Explanation

  RFC 2833/4733 is correct because the exam topics explicitly include DTMF troubleshooting and configuration using that relay method. SIP INFO only, H.245 alphanumeric, and CAS signaling are not the targeted answer in the current blueprint scope.

• Question 537:

  On a Cisco Catalyst Switch, which command is required to send CDP packets on a switch port that configures a Cisco IP phone to transmit voice traffic in 802.1Q frames, tagged with the voice VLAN ID 221?

  A. Device(config-if)# switchport access vlan 221
  B. Device(config-if)# switchport trunk allowed vlan 221
  C. Device(config-if)# switchport vlan voice 221
  D. Device(config-if)# switchport voice vlan 221
  D. Device(config-if)# switchport voice vlan 221

  ---

  Explanation

  switchport voice vlan {vlan-id | - vlan-id-Configure the phone to forward all voice traffic through the specified VLAN. By default, the Cisco IP Phone forwards the voice traffic with an IEEE 802.1Q priority of 5. Valid VLAN IDs are 1 to 4094.

• Question 538:

  Which statement describes the outcome when the trust boundary is defined at the Cisco IP phone?

  A. Packets or Ethernet frames are remarked at the access layer switch.
  B. Packets or Ethernet frames are not remarked by the IP phone.
  C. Packets or Ethernet frames are not remarked at the layer switch.
  D. Packets or Ethernet frames are remarked at the distribution layer switch.
  C. Packets or Ethernet frames are not remarked at the layer switch.

  C. 6970 / TCP

• Question 540:

  Which two technical reasons make QoS a necessity in a video deployment? (Choose Two)

  A. Low response time between endpoints

  D. Bursly behavior of video traffic
  C. Variable bit rate of the video stream
  D. Bursly behavior of video traffic
