On the same device, congestion avoidance is better than congestion management.
- A . True
- B . False
Which packets can Huawei equipment perform traffic suppression on? (Multiple choice)
- A . Multicast
- B . Known unicast
- C . Broadcast
- D . Unknown unicast
Which of the following technologies can be used to isolate different users in the same VLAN?
- A . IPSG
- B . Port isolation
- C . Super VLAN
- D . Ethernet port security
When EVPN serves as the control plane to carry L3VPN or L2VPN services, which of the following types of tunnels can be combined with the data forwarding plane? (Multiple choice)
- A . SR-MPLS
- B . QinQ
- C . SRv6
- D . VXLAN
Suppose you need to deploy a wireless network in a hospital ward. Which of the following deployment methods is most suitable for achieving wireless coverage at low cost?
- A . Leader AP
- B . Cloud management AP
- C . Agile distributed AP
- D . AC+FIT AP
In the Huawei Cloud wide area network solution, IGP serves as the basic supporting protocol to realize the collection and flooding of the three-layer topology of the entire network, and cooperates with protocols such as TWAMP/iFIT to collect link delay and other SLA information in the network.
- A . True
- B . False
In the scenario of dynamically establishing a VXLAN tunnel through BCP EVPN, when using BGP EVPN Type2 routing for host MAC address advertisement, which of the following descriptions is correct?
- A . It will carry specific L2 VNI and L3 VNI values at the same time.
- B . Will carry specific L3 VNI value
- C . The RT value carried is the Export RT in the IP VPN instance.
- D . The IP Address and IP Address Length fields will not carry specific content.
In different scenarios, RSTP provides different protection functions. Which of the following is wrong?
- A . For a designated port with root protection enabled, its port role can only remain as a designated port.
- B . After enabling the anti-TC-BPDU packet attack function, the number of times the switching device processes IC BPDU packets within a unit time can be configured.
- C . After the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set as a non-edge port and the spanning tree calculation will be re-calculated.
- D . Enable root protection on the designated port. When the port receives a better RST BPDU, the port will enter the Discarding state and no longer forward packets. If the port does not receive a better RST BPDU within a period of time, it will automatically return to the normal Forwarding state.
