First line

Message body

6. Under the H.248 protocol, if the signaling IP and media IP are both 10.1.1.100/8 and the voice gateway is 10.1.1.1, when configuring the voIP service, which of the following commands is wrong?

Use the command ip address media 10.1.1.100 10.1.1.1 to configure the media IP in voip mode

Use the reset cold start command under the voice interface to make the interface attribute configuration effective

Use the if-h248 attributei command to configure interface attributes under the voice interface

Use the command ip address signaling 10.1.1.100 10.1.1.1 in voip mode to configure the signaling IP

7. When the invitation message sent by user A reaches user B after passing through servers C, D, and E, in which order is the server address recorded in the VIA field in the message received by user B from top to bottom?

C->D->E

E->C->D

E->D->C

C->E->D

8. The Max-Forwards field can be used in S1P messages to resolve loops and avoid endless message forwarding.

True

False

9. Which is the correct multicast MAC address corresponding to the multicast IP address 227.120.1.32?

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

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

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

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

10. In the Huawei U200 management system, when adding access network elements, you can only add them one by one.

True

False

11. What methods can be taken when the OLT processes priority marking? (Multiple choice)

Copy/mapping from the inner tag802.1p of the ingress message priority

Copy the Tos value of the ingress message

Directly specify the configuration

Copy/mapping from the outer Tag802.1p of the ingress message priority

12. OLT usually uses queue scheduling technology to solve traffic congestion. How many queues does the OLT have?

13. What are the main congestion management technologies in OLT? (Multiple choice)

WRED

WRR

PQ+WRR

14. Which of the following statement about SSH connections is wrong?

From the client side, SSH provides two levels of security verification.

SSHi protocol works at the network layer

SSH protocol can encrypt all transmitted data, effectively preventing information leakage during remote management

SSH can be applied to remote encrypted connections, file transfer encryption

15. Which statement is wrong about DHCP option 82? (Multiple choice)

The DHCP Option 82 port configuration on the OLT is enable by default

When the DHCP client sends a request message to the DHCP server, if it needs to go through the DHCP relay, the DCP relay will add Option 82 to the request message.

DHCP Option 82 switches are divided into four levels: global level, port level, service virtual port level and LA level. Only when all the switches are turned on will the system add ption82 information to the upstream DCP packets.

The DHCP client sends the request message in the form of unicast during initialization.

16. What are the main solutions to MAC address spoofing? (Multiple choice)

Replace user terminal

Automatic MAC address binding

Manually configure a static MAC address

Limit the number of users’ MAC address learning

17. Which of the following types of DBA bandwidth will the remaining upstream bandwidth of the PON port be reduced after the DBA template is configured and successfully used by the OT to go online? (Multiple choice)

assure

fixed

max

best effort

18. Which of the following statements about 10GEPON are correct? (Multiple choice)

The frame protocols of 10G EPON and EPON are compatible.

10G EPON/EPON compatibility, that is, 10G EPONESONU can coexist with the same ODNT with 1G EPON ONU.

10G EPON technology follows the IEEE 802.3av standard, supports asymmetrical transmission rates of 10Gbit/s downstream and 2.5Gbit/s upstream, meeting high bandwidth

The MPCP protocol of 10G EPON is the same as the IPCP protocol of EPON.

19. When dealing with voice faults, sometimes it is necessary to capture packets for fault analysis. If the user ID of the calling user in the captured SIP message is displayed as Sip: 2270[email protected], which description is wrong? (Multiple choice)

The server port is 5060

The transport layer protocol uses TLS

The user phone number is 2270808

The host IP address is 191.169.1.112

20. Which of the following options can be used to carry the SIP protocol? (Multiple choice)

RTCP

TLS

SCTP

TCP
