NO.37 When ont fails or the hardware needs to be replaced, the ONT service needs to be replaced, and then the ONT
service needs to be removed on the OLT, and then the new ONT service needs to be registered

wrong

Right

NO.38 (Single choice) When planning qos, it is necessary to plan reasonably according to the business, and adopt the
() scheduling mode for high-priority businesses.

WRR

NO.39 In Huawei’s u2000 management system, when adding network elements, you can only add — ones- when you
access the network element.

wrong

Right

NO.40 (Radio) The following is not the QOS service model, is

Diffserv

Intserv

FIFO service

Best Effort

NO.41 The establishment, maintenance and dismantling of the word path between the SIP user and the server are
done through the interaction of the –series of messages, so that every information contained in the SIP text has
a –nature, There is no phenomenon in which a single information value appears multiple times.

wrong

Right

NO.42 (Single choice) The following statement about the PITP protocol is incorrect

The PITP protocol includes pitp P mode and PITP V mode

The purpose of the PITP feature is to provide the upper authentication server with the physical location
information of the access user, and the BRAS device can realize the user account and the press position
after obtaining the user access location information

Bind the authentication of the information to avoid the theft and roaming of the user account

In pitp V mode, the user’s physical location information is added to the PPPOE message sent by the user
side to cooperate with the upper-level server for user authentication

PITP P mode can also be called PPOE+ mode

NO.43 (Multiple select) When there is a backbone fiber break or OLT does not detect the expected optical signal
(L0S) alarm, the possible cause is that

Rogue ONU exists under the port

The port backbone fiber is faulty

Any power loss or failure under the port

The port laser is turned off

NO.44 (Radio) To improve link reliability, the LT device passes through two upstream ports 0/19/0 and 0/20/0
Configure the Timedelay protection group, which of the following commands is optional

huawei(config)#interface giu 0/19
huawei (config-if-giu-0/19)hoffline-tx-off-time 0 500

huawei(protect-group-0)hprotect-group member port 0/19/0 role work

huawei(protect-group-0)aprotect-group enable

huawei(config)=protect-group 0 protect-target sth-nni port workmode timedelay

NO.45 In esight’s OnT zero configuration deployment, do not provision OLT when incrementally configuring OLT.

True

False

NO.46 (Radio) In the FTTB/C scenario, ONU is used as an AG device to access the phone, and there is no possible
cause of sound failure for SIP protocol off-hook

There are packet losses in the olt upper-layer network

The ONU side MG interface status is abnormal

The voice server is down

ONU and IMS routes are unreachable

NO.47 In the evolution of EPON to 10g EPON, a smooth transition is achieved at the local end by adding AWDM
WDM module, and Odn coexists.

True

False

NO.48 Under IGMP snooping, there are two users on demand under the OLT- the same program, and the olt sends
two join messages to the multicast router

wrong

Right

NO.49 (Single choice) The following statement about ssH connection is incorrect, yes

ssH can be applied to remote encryption of encrypted file transfers over remote encryption connections

The ssH protocol encrypts all transmitted data, effectively preventing information leakage problems
during remote management

From a client perspective, SSH provides two levels of security authentication.

The ssH protocol is working at the network layer

NO.50 The (radio) device periodically sends and receives LMCP packets to avoid information loss, and if packets are
not received during ( ) LACp packet interaction cycles, the system considers the port to be down

NO.51 (Radio) follow the multicast IP address 227. The correct multicast MAC address corresponding to 120.1.32 is

01-00-5e-78-01-32

01-00-5e-14-01-20

01-00-5e-78-01-20

01-00-5e-14-01-32

NO.52 (Radio) The downstream effective bandwidth of the GPON PON port is

1.25G

2.5G

2.2G

NO.53 (Single choice) The following statement about defense MAC Spoofing is wrong

MAC Anti- Mac Spoofing’ features are mutually exclusive with WMAC, SC, PPPOE SMAC features at
the VLA level

After the anti-MAC Spoofing function is enabled, the system automatically implements the dynamic
binding of the AC address to the service flow

After enabling the Anti-MAC Spoofing function, for IPoE users using fixed IP, the user needs to be
statically configured

Turning off the Anti-MAC Spoofing function can only take out the fixed table items, which does not
affect the user’s service application, but the service forwarding surface will be interrupted.

NO.54 (Multiple choice) When the OLT main control board CPU is detected to be continuously elevated, the
following possible causes are?

The user logged in illegally

Network loops

Cyber attacks

Rogue ONU

NO.55 The (radio) prerequisites for esight to automatically discover OLT and MXU devices by IP address are not
included

Esight and the device need to be on the same network segment, otherwise the device cannot be
discovered using the ARP broadcast protocol.

You already have the operation permission of “Resource Access”.

Esight and the device can be routed to communicate (ping each other).

The SMMP parameters on the esight side have been configured and are aligned with the device side SP
parameters.

NO.56 Max-Forwards fields can be used in S1P messages to solve loop problems and avoid endless packet
forwarding.

wrong

Right

NO.57 (Multi-select) VLAN planning principles need to be considered

The total number of VLANs

Customer type and number of users

Type and type of business

Uplink networking mode

The networking topology of the OLT
