After the loading is completed, the active/standby switchover is performed

AISCA loads the A2SCA software package

Insufficient space on the CF card

After the loading is completed, the active/standby switchover is performed

When the device reports the PW_APS_DEGRADED alarm, what is the problem with the LTE service carried by the station?

The working protection channel has a channel failure

The working protection channels are invalid

None of the working protection channels fail

MPLS was originally proposed to improve the forwarding speed of routers. It integrates the advantages of IP and ATM. What are the characteristics?

Connection-Oriented Forwarding Plane

Connectionless-oriented control plane

Connectionless-oriented forwarding plane

Connection-Oriented Forwarding Plane

Connection-Oriented Control Plane

Connectionless-oriented control plane

Which of the following descriptions about routing loops is wrong?

Routing loops can only be generated by dynamic routing protocols

Routing loops may occur when different routing domains import routes from each other

Routing loops can only be generated by dynamic routing protocols

Routing loops prevent packets from reaching their destination correctly and cause link congestion

The packet is routed circularly between two or more routers until the TTL is reduced to 0 and discarded

Which of the following descriptions about bit errors in the SDH network is wrong?

B1, B2, B3 can only detect the even number of errors in a block, and the odd number of errors cannot be detected

B1, B2, B3 can only detect the odd number of errors in a block, and the even number of errors cannot be detected

Through B1, B2, B3, the bit errors of the regeneration section, multiplex section and high-order channel can be detected respectively

Bit error means that after receiving, judging, and regenerating, some bits in the digital code stream have errors.

When the switch is working, the device forwards data according to the MAC address forwarding table. Which of the following descriptions is correct?

The destination address of the message is a unicast MAC address, then look up the MAC address table, and if found, forward the frame to the corresponding port (excluding the source port)

The destination address of the packet is a unicast MAC address, but there is no corresponding entry in the MAC address table, the packet is discarded

If the MAC address entry of the device reaches the upper specification limit of the device, the device cannot learn a new MAC address entry, and the data packet is discarded.

If the destination MAC address of the packet is the broadcast MAC address, it will be flooded to all ports including the source port.

The destination address of the message is a unicast MAC address, then look up the MAC address table, and if found, forward the frame to the corresponding port (excluding the source port)

Which of the following ways does the Inspector inspection tool support adding network elements?

Import network elements in batches

Automatically discover network elements

Import network elements in batches

Which of the following are the possible reasons for the disconnection of network elements?

All the optical paths to the NE are faulty

Failure of the main control board of the network element

The gateway network element connection is interrupted

All the optical paths to the NE are faulty

Failure of the main control board of the network element

The gateway network element connection is interrupted
