Which of the following routing types does EVPN use to achieve fast convergence and split horizon?
- A . Inclusive Multicast Route
- B . MAC/IP Advertisement Route
- C . Ethernet Segment Route
- D . Ethernet AD Route
Which of the following token bucket technologies is used for traffic shaping?
- A . Single barrel single speed
- B . Double barrel double speed
- C . Double barrel single speed
- D . Single barrel double speed
The naming of SRv6 instructions follows certain rules, and the instruction function can be quickly determined from the naming combination.
Which of the following descriptions of keywords in SRv6 directive names are correct? (Multiple choice)
- A . V: forwarding based on VPN instance routing table lookup
- B . X: Designate one or a group of Layer 3 interfaces to forward packets.
- C . T: Query the routing table and forward the message
- D . M: Query the Layer 2 forwarding table for unicast forwarding
A certain campus deploys the OSPF protocol to achieve network interoperability. The LSDB information of R2 is as shown in the figure.
Which of the following information derived from this LSDB is correct? (Multiple choice)
- A . Area1 is the NSSA area
- B . R2 delivers the default route within the OSPF process.
- C . R2 converts the default route of Type7 LSA into the default route of Type5 LSA
- D . There is no Type3 LSA in Area1. It may be that R2 filters Type3 LSA in the outbound direction of Area1.
ISP convergence speed is faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device can remain () within the set linkage time router, so that the link metric value in the LSA it publishes is the maximum value, thereby telling other OSPF devices not to use this router to forward data to avoid traffic loss.
What you use the "display current-configuration" command to view is the configuration running in the memory.
- A . True
- B . False
There can be multiple nodes under a route-policy. Different node numbers are identified by node. Each node can have multiple if-match and apply clauses. Which of the following descriptions are wrong? (Multiple choice)
- A . There is an "AND" relationship between the if match clauses under each node.
- B . There is an "or" relationship between the if-match clauses under each node
- C . There is an “AND” relationship between different nodes.
- D . There is an “or” relationship between different nodes
The network administrator enters display telemetry sensor on the device to view Telemetry related information. The following is displayed. Which of the following descriptions is wrong?
- A . The device can continue to add Telemetry sampling paths
- B . The name of the sampling sensor is Sensor1
- C . The device is configured with three Telemetry sampling paths
- D . This subscription method is dynamic subscription
SRv6 completes hop-by-hop forwarding of packets by inserting a routing extension header SRH into IPv6 packets.
Which of the following descriptions about the SRH extension header is wrong?
- A . When the Routing Type field value is 4, it indicates an SRH extension header.
- B . This extension header specifies an explicit path to IPv6 and stores IPv6 Segment List information.
- C . The Segments Left field indicates the number of intermediate nodes that should still be visited before reaching the destination node.
- D . Segment List is the address form of IPv6, indicating the destination IPv6 address of the node that needs to be accessed.
In Huawei Cloud wide area network solution, the controller can plan traffic paths based on real-time network performance and deliver path information through PCEP or BGP-LS.
- A . True
- B . False
