質問36
The (radio) 10G GPON system uses XGEN frames to encapsulate data, and the PORT ID is defined in the
XGEN header as () bits.

質問37
(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.

質問38
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.

質問39
The maximum spectroscopic ratio supported by 10G EPON is?

1: 256 (Laboratory).

1:32

1:128

1:64

質問40
The ascending wavelength of the (radio) 10G EPONE is?

1577nm

1270m (symmetrical).

1310m (asymmetrical).

1490nm

質問41
(Single choice) When planning qos, it is necessary to plan reasonably according to the business, and adopt the
() scheduling mode for high-priority businesses.

WHY

DRR

WRR

質問42
The number of users under the OLT can also determine whether the VLA is single-layer or dual-layer VLA.
Single-layer VLANs can be used when the number of users is small, and dual-layer VLANs must be used
when the need to distinguish services and the number of users is second to ().

質問43
(Radio) Regarding multicast, the following description is incorrect

Add Lgmp user under BTV, and by default, multicast users can watch 8 programs.

The user-issued Report is captured in the single board logic and sent to the single board CPU

Device-based global configurations of Layer 2 groups refer to common parameters of protocols ( IGMP
Proxy, GMP Snoop) to all

When the igmp match mode disables, you need to configure the multicast program group

質問44
(Multi-select) Query ppPOE simu-lation results on the MDU side as follows
From the query results, it can be judged ()

The service configuration of ppPoE users is normal

PPPoE user account and authentication method are correct

The link between MDU tone setting and BRAS is ok

The MDU management IP is configured correctly

質問45
(Radio) 10G GPON system downlink wavelength is

1310nm

1577nm

1270mm

1490nm

質問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

質問47
The Class D multicast address range is from 224. 0 0 0 to 238. 255 255 255

真

偽

質問48
(Radio) When the 0LT global or VLAN service template enables the PITP switch, the service port allows the
upstream packet to be carried, the Vendor tag switch, and the user to carry the vendor upstream packet In the
case of tarf information, the following statement regarding olts to PITP message processing strategies is
correct

OLT adds a local Vendor tap to the upstream PITP packet

OLT forwards the USER-side PITP message directly without any processing

OlT is left with the Vendor tag carried in the upstream PITP message, plus the local Vendor tag

OLT drops upstream PITP packets

質問49
(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

質問50
Type B protection provides redundant protection for both OLT PON ports and backbone fibers when OLT or
OLT PON If the port or trunk fiber fails, manually switch to another – luguang.
