Huawei H31-311_V2.5 Dumps

OSN1500/2500/3500/7500 supports DC and AC power inputs.

According to ITU-T's recommendations, the requirement that the MSP switching time should be within 50ms is conditional. For example, the number of net elements on the entire ring network is less than 16.

For (on-premises) HA solutions where active and standby servers are deployed in the same location, which of the following platforms can be deployed? (Multiple choice).

Which of the following is the default WTR time for MSP switching?

If you group SNCP services with the same source, sink, or route, you can increase the SNCP switching speed

Which of the following layers define the protocols that control the network layer? The protocol for this layer applies to logical links, i.e. end-to-end connectivity between two devices.

Which of the following statements about the OTM-n .m and OTMnr .m for OTN are incorrect?

Optical module parameter "L-64.2" in "2" indicates which of the following working windows?

When the U2000 is synchronized, the same network metadata as the U2000 is not uploaded to the U2000, and the data that exists on the U200 but does not exist on the network element is deleted.

Which of the following logic function blocks are involved in processing clock signals? (Multiple choice).

For alignment; Indicates the starting position of VC-n in the corresponding AU or TU frame. • This way: The receiver can correctly remove the corresponding VC from STM-N, and then The VC and C packages are separated into separate low-rate signals, such as PDH, which means that the low-rate path signal can be dropped directly from the STM-N signal.

Frame-Mapped GFP (GFPF> is a processing mode that targets data encoding blocks such as Fibre Channel and ESCON.

When the bridge uses ivl learning mode, an entry in the MAC address table is created based on the source MAC address and source port of the teach frame. This entry applies to all VLANs

In WDM systems, it is ideal to use a dielectric thin problem filter (TFF) when using less than () wavelengths.

Which of the following is the feature of TCM overhead in ODUk signals?

Which of the following alerts does not trigger an AU-AIS alert?

The number of bit error blocks on each VC4 channel is detected by B3 on the receiving side. At the same time, the information is sent back to the sender via Q, and HP-REI and HP-FEBBE report on the sender.

For MSPs, you need to set the MSP protocol ID for each NE. To ensure that each ID is unique, it is recommended to set the MSP protocol ID to the value that is compatible with the network element ID.

When using a script to back up U2000 data, the backup speed is fast because the backup file is small.

Linear MSP (LMSP) has two modes: 1+1 and 1:1. Additional services can only be configured for the protection channel in 1:1 mode of the LMSP.

Which of the following communication protocols are used for DCN management of Huawei devices? (Multiple choice).

Which of the following statements about the MST functional module is correct? (Multiple choice).

MSP is a network-level protection scheme. MSF does not directly protect services, and MSP switching and recovery are not affected even if there is no service on the MSP ring.

On a Layer 2 switching device, if the Ethernet port is an Access port, the port can only receive Ethernet frames without a VLAN tag or Ethernet frames with the same VLAN ID as the default VLAN ID of the port.

In the SDH optical synchronous transmission system, which of the following bytes is used to transmit the quality and weight and usage information of the clock source?

Which of the following statements regarding the protection of the cross-connecting plate 1+1 is correct? (Multiple choice).

Which of the following technologies is the main difference between an open DWDM system and an integrated DWDM system?

The index is used to folio and delineate the starting position of VC-n in the corresponding AU or TU frame so that the receiving end can correctly remove the corresponding VC from the STM-N The VC and C packages are then separated into separate low-rate signals, such as PDH That is; Low-rate branch signals can be discarded directly from the STM-N signal

Which of the following is not the advantage of WDM?
