A terminal failed to register with GK and found that the rejection code of GK was gkRejGkNoEnoughRegTable. Which may be caused?
- A . When SwitchCentre defines the terminal to use password authentication, the password provided when the terminal initiates a registration request to SwitchCentre is incorrect.
- B . Network segment bandwidth restrictions are configured on SwitchCentre.
- C . Non-standard terminals register with SwitchCentre. The registration signaling is illegal and fields are missing.
- D . When the number of nodes registered on SwitchCentre has reached the value specified by the license
Network recording supports downloading recorded video files to the local in which format and supports local playback?
- A . FLV
- B . WMV
- C . RMVB
- D . MTV
The IP of a private network terminal is 10.1.0.10, the static NAT export address is 61.1.0.10, the GK address is 61.1.0.11, and there is another public network terminal: 61.1.0.12. At this time, the public network terminal calls the private network in point-to-point IP mode, which is calling address?
- A . 10.1.0.10
- B . 61.1.0.10
- C . 61.1.0.11
- D . 61.1.0.12
Under static NAT networking, the packets sent by private network terminals through the firewall will be changed. Which of the following descriptions is wrong?
- A . The terminal RAS addr changes to the address after NAT
- B . The terminal CS addr changes to the address after NAT
- C . NAT addr is the public network exit address of the firewall
- D . GK RAS addr becomes the address after NAT
During a call using the H.323 protocol, the RRQ message Payload of the calling site contains Caller RAS Addr, Caller number, and Caller CsAddr.
- A . True
- B . False
After enabling NAT settings on the video conferencing terminal, the content of the packets can be changed. It can be used in static NAT networking mode or DNAT/NAPT networking.
- A . True
- B . False
In the default configuration of the firewall, communication from a high-security network (intranet) to a low-security network (Internet) is generally not restricted, but the firewall will block it on the other hand.
- A . True
- B . False
See networking. Assume that all terminals have been registered to GK/SC, there are no port restrictions on NAT1 and NAT2, and all terminals are TE30 terminals (H.323). Then T1 calls T3. Which of the following description is correct?
- A . GK routing is required
- B . Unable to communicate with each other
- C . Can communicate directly with each other
- D . Requires MCU routing
Which is the core reason why video conferencing supports public and private network traversal?
- A . There is a firewall or NAT, so public and private network traversal must be supported.
- B . Signaling and media transmission channels are not unified
- C . There is a media transmission address in the signaling, and the NAT device only performs address translation on the IP header, so public and private network traversal processing is required.
- D . Because the network performs address translation on IP packets
The network on the TP3106 wall is connected to which port of the switch by default?
- A . 1
- B . 11
- C . 12
- D . 21
