210-065 Implementing Cisco Video Network Devices (CIVND)

QUESTION 1
Which of the following commands or command sets should you issue to configure a Cisco TelePresence System 1000 with IP address 192.168.1.43,
subnet mask 255.255.255.0, and default gateway 192.168.1.1?
A. static 192.168.1.43 255.255.255.0 192.168.1.1
B. ip address 192.168.1.43 255.255.255.0 192.168.1.1
C. set network ip static 192.168.1.43 255.255.255.0 192.168.1.1
D. xConfiguration Network 1 IPv4 Address: “192.168.1.43”
xConfiguration Network 1 IPv4 SubnetMask: “255.255.255.0”
xConfiguration Network 1 IPv4 Gateway: “192.168.1.1”
E. ip address 192.168.1.43 255.255.255.0
ip defaultgateway 192.168.1.1

Correct Answer: C

Section: Troubleshooting and Support Explanation
Explanation:
You should issue the set network ip static 192.168.1.43 255.255.255.0 192.168.1.1 command. The syntax of the set network ip static command is set
network ip static ip-address subnet-mask default-gateway [dnsaddress1] [dnsaddress2] [domain]. After you configure the static IP address, the Cisco
TelePresence System (CTS) 1000 will automatically restart.
You can also configure a static IP address on a CTS 1000 by using the web interface. To configure a static IP address by using the web interface,
navigate to Configuration > IP Settings, change DHCP Enabled to No, and configure the IP address, subnet mask, and default gateway fields.
You should not issue the static 192.168.1.43 255.255.255.0 192.168.1.1 command. The static command configures a static IP address for a port on the
Cisco TelePresence multipoint control unit (MCU) 5300. The syntax of the static command is static port ip-address subnet-mask [default-gateway],
where port is A for Port A or B for Port B.
You should not issue the ip address 192.168.1.43 255.255.255.0 192.168.1.1command. The ip address command is not valid on a CTS 1000.
You should not issue the following command set:
xConfiguration Network 1 IPv4 Address: “192.168.1.43”
xConfiguration Network 1 IPv4 SubnetMask: “255.255.255.0”
xConfiguration Network 1 IPv4 Gateway: “192.168.1.1”
You would issue these commands to configure a static IP address on a CTS Codec, such as the C40 or C60.

You should not issue the following command set:
ip address 192.168.1.43 255.255.255.0
ip defaultgateway 192.168.1.1
This command set is similar to the IP address configuration of a Cisco router or switch. However, these commands are not valid on a CTS 1000.

QUESTION 2
Which of the following will not be affected when you issue the xCommand SystemUnit FactoryReset Confirm: Yes command on a Cisco TelePresence
EX, MX, SX, or C-series system? (Choose two.)
A. call logs
B. certificates
C. custom backgrounds
D. local phonebook
E. option keys
F. release keys
G. ring tones
H. system parameters

Correct Answer: EF

Section: Troubleshooting and Support Explanation
Explanation
Explanation/Reference:
Section: Troubleshooting and Support Explanation
Explanation:
Release keys and option keys will not be affected when you issue the xCommand SystemUnit FactoryReset Confirm: Yes command on a Cisco
TelePresence EX, MX, SX, or C-series system. The xCommand SystemUnit FactoryReset Confirm: Yes command is used to perform a factory reset on
a system. You might want to perform a factory reset if there is a severe problem with the video system. If possible, you should back up log files and the
current configuration before proceeding with a factory reset.
The following items are deleted when you perform a factory reset:
Call logs
Custom backgrounds
Ring tones
Certificates
Local phonebook
In addition, all system parameters are set to their default values.

QUESTION 3
During a call, you discover that you are unable to control the remote camera from your Cisco TelePresence SX20 Quick Set endpoint.
Which of the following reasons might cause this behavior to occur? (Choose two.)
A. The call is encrypted.
B. The remote camera does not have PTZ functionality.
C. The Conference FarEndControl Mode setting on your system is set to Off.
D. The Conference FarEndControl Mode setting on the remote system is set to Off.
E. Remote cameras cannot be controlled from an SX20 endpoint.

Correct Answer: BD

Section: Endpoint Configuration Explanation
Explanation
Explanation/Reference:
Section: Endpoint Configuration Explanation
Explanation:
You will be unable to control the remote camera from your Cisco TelePresence SX20 Quick Set endpoint if the Conference FarEndControl Mode setting
on the remote system is set to Off or if the remote camera does not have pan-tilt-zoom (PTZ) functionality. If the Conference FarEndControl Mode
setting on your system is set to Off, remote participants will be unable to control your camera.
Encryption does not prevent control of remote cameras. However, encryption does affect the remote snapshot feature? snapshots are disabled on
encrypted calls.
You can also change the local or remote layout from a Cisco SX20. The following video layout options are available:
Auto
Equal
Overlay
Prominent
Single
The Auto layout option uses the default layout family. The Equal layout option displays all participants in pictures of the same size as long as there is
enough space on the screen to display them. The Overlay layout option displays the active speaker or presentation in a full screen and displays the
other participants in small pictures-in-picture (PiP). The Prominent layout option displays the active speaker or presentation in a large picture and
displays the other participants in small pictures. The Single layout option displays only the active speaker or presentation? the other participants are not
displayed.

QUESTION 4
Which codec is the default video compression format for most Cisco IP video endpoints?
A. G.711
B. G.729
C. H.261
D. H.263
E. H.264

Correct Answer: E

Section: Video Concepts Explanation
Explanation
Explanation/Reference:
Section: Video Concepts Explanation
Explanation:
264 is the default video compression format for most Cisco IP video endpoints. Video formats, which are commonly referred to as codecs, specify how
video compression is to be handled. H.261 and H.263 are also video codecs. However, neither H.261 nor H.263 supports HD video. By contrast, H.264
supports HD video.
G.711 and G.729 are not video codecs; they are audio codecs. G.711 provides higher-quality audio output but requires more bandwidth. G.729 provides
lower-quality audio output and requires much less bandwidth; however, G.729 does not transmit fax signals, touch tones, or any other type of complex
audio very well.

QUESTION 5
You issue the xStatus Camera command on a Cisco SX20 and receive the following output:

210-065-1

Which of the following statements is true?
A. The SX20 has the best possible camera installed.
B. The camera is pointed up.
C. The camera is pointed to the left.
D. The image can be flipped horizontally.
E. The camera is configured to auto focus.

Correct Answer: B

Section: Troubleshooting and Support Explanation
Explanation
Explanation/Reference:
Section: Troubleshooting and Support Explanation
Explanation:
The camera is pointed upward. The Position Tilt value indicates whether the camera is pointed upward or downward. If the value is negative, the camera
is tilted downward; if the value is positive, the camera is tilted upward.
The xStatus Camera command can be used to display status information about a camera. The same information can be obtained from the web
interface by navigating to Configuration > System Status > Camera.
The Position Pan value indicates whether the camera is pointed to the left or to the right. If the value is negative, the camera is pointed to the left; if the
value is positive, the camera is pointed to the right. In this scenario, the value is 334, so the camera is pointed to the right.
The Flip value indicates whether the camera can be flipped vertically, not horizontally. You can configure the Flip value to a value of Auto, On, or Off. If the value is set to Auto, the camera image will flip vertically if the camera is upside down.
The xStatus Camera output does not indicate whether a camera is configured to auto focus. However, you can configure a camera to auto focus by
issuing the xConfiguration Cameras Camera 1 Focus Mode: Auto command.
The SX20 in this scenario does not have the best possible camera installed. The SX20 can be configured with a 2.5x, 4x, or 12x camera. The model
number indicates what kind of camera is installed. In this scenario, the SX20 is configured with a 4x zoom camera.
