質問100、 When creating a PTN tunnel, you can set the priority of the tunnel. There are 0, 1, and 7. The larger the value, the higher the priority.

True

False

質問101、 Which of the following descriptions about routing loops is wrong?

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

質問102、 Which of the following descriptions about the use of detection packets in the PTN LTE scheme BFD is correct?

CCM message

CV message

FFD message

Lightweight HELLO message

質問103、 What options are included in the role of the control word in PWE3?

Carry the sequence number forwarded by the packet

Fill the message to prevent the message from being too short

Carrying Layer 2 frame header control information

Carry MPLS labels

質問104、 PTN’s ACR time sodium and 1588 clock can achieve time synchronization.

True

False

質問105、 Which of the following paths can be configured on the network management?

OMS

CLIENT

ODUK

OCH

質問106、 The base station is deployed, the Tunnel and PW tests are normal, and the base station management is normal, but the base station cannot access the core network normally.
What is the reason for the impossibility?

The IP addresses of the PTN equipment interconnection interfaces are not in the same network segment

User packets carry VLAN, but the port attribute is Access

On the L2L3PTN node, the L3VE termination VLAN segment does not include the base station’s VLAN segment

There is no route to the address managed by the SGW on L2L3

質問107、 In the PTN network, what are the parameters for measuring QOS?

Delay

Jitter

Bandwidth

Packet Loss Rate

Bit Error Rate

質問108、 0TUK_LOF is a 0TUK layer alarm, which means the OTuk frame is lost, the FAS frame alignment is detected, and the alarm is reported when the frame is out of synchronization for 5ms. The alarmends after the frame synchronization state is restored for 5ms.

True

False

質問109、 opt Datacollector supports black box fault data collection of multiple products. Which of the following products is not supported?

NG SDH

WDM

ocs

PTN

質問110、 Through the northbound interface, the U2000 can flexibly connect with different third-party network management systems, providing physical storage and reporting data information for the upper-layer network.

True

False

質問111、 According to the IEEE 802JQ standard, where is the VLAN ID field on the Ethernet?

Before source MAC address and destination MAC address

Between the source MAC address and the destination MAC address

After the source MA dog address and the destination MAC address

not fixed

質問112、 Which of the following is incorrect about the job description of a hub?

HU is a physical layer device

HUB. is the data link layer device

HUB connects multiple terminal devices together to form a star network through ports

The shared bus technology is used inside the HUB device, and the CSMA/CD technology is used for interaction

質問113、 In the PTNLTE non-load sharing scheme, the main L3 configuration is used to configure the route tracking multi-hop BFD scheme to prevent loops. Which of the following configurations needs to be performed?

Create a loopback interface address on the active L3

Create the BFD between the main L3 Loopback interface device L3 and the EPC port

The standby L3 configures the standby traceroute BFD to the EPC

The primary L3 configures the backup traceroute BFD to the EPC

質問114、 Which of the following ways does the Inspector inspection tool support adding network elements?

Automatically discover network elements

Manually add network elements

NEs actively report

Import network elements in batches

質問115、 Which of the following bridges are used to forward data based on the MAC address and VLAN ID carried in the data?

802.1a

802.1d

802.1q

802.11ab

質問116、 Which of the following statements is incorrect about the optical layer interfaces OTM-nm and OTM-nrm of OTN?

n represents the number of wavelengths carried by the maximum capacity,

m represents the rate. Value can be 1.2 or 3.

r means OTM without OSC function

OTM-nr.m with OSC signal is OTM-nm.

質問117、 PTN can support in-band DCN. At this time, the port needs to enable the DCN function. Therefore, in CES service, PTN setup cannot be managed by in-band DCN.

True

False
