Question No : 2
Which of the following is incorrect about the design principle of Locator SID?

A.When planning the SRv6 locator address segment, set an appropriate mask based on the number of IPv6 SIDs that the device may use.
B.loatos svW6_locator ipu6-prelix21.DBBABCD: .b4 static 32, Locator is 2001.DB8.ABCD:, length 64 bits, static segment occupies 32 bits, dynamic segment occupies 32 bits, args field occupies 0 bits. Dynamic segment starting value: 2001: DB8: ABCD: 0000: 0000: 0000: 0000: 0001
C.Locator SID supports static configuration or dynamic allocation. end-op and end-m must be statically configured. Static configuration is also recommended for end and end.x to facilitate network operation and maintenance. Other SIDs can be dynamically allocated.
D.Devices at the same site belong to the same large network segment with the same prefix, and different devices are assigned small network segments with the same prefix in the large network segment.

Question No : 5
In QOS design, which is the incorrect description of the traffic scheduling design principle?

A.The scheduling strategy of the entire network should be kept unified, and template deployment should be used as much as possible to facilitate network management.
B.LPQ/WFQ scheduling strategies can be used to prevent low-priority services from not being able to obtain bandwidth resources
C.The currently planned QoS strategy needs to take into account the subsequent expansion of the network
D.Core services and video and voice services must be given absolute priority in forwarding and use PQ scheduling
E.Unless there are special business requirements, some parameters of the scheduling strategy should use the default values as much as possible.
F.For TCP-based services, queues must be configured with WRED discard to avoid TCP global synchronization

Question No : 6
When designing BGP in SDN-WAN, it is recommended to group devices with the same configuration into the same group to simplify configuration and maintenance.
Which of the following descriptions is incorrect?

A.All backbone P (P) 1 group
B.All branches PE (BR-PE) 1 group
C.All data center PE (DC-PE) 1 group
D.All RR devices (RR) 1 group

正解:

Question No : 7
In the SDN-WAN solution, which principles that need to be followed in ISIS Cost design are incorrect?

A.The link cost of the operator's MSTP in a different location is relatively high. It is recommended to configure 1000 to avoid traffic bypassing the wide area link.
B.The COST configuration of the link using wavelength division or bare fiber in the same city is the second smallest. The recommended configuration is 200 to ensure that the route calculation is second to the link in the same city.
C.The local link COST value is configured to be the minimum, and the recommended configuration is 10 to ensure that the routing calculation takes the local link first - test error
D.The link COST between the RR and PE devices is configured with an extremely large value. The recommended configuration is 10000 to ensure that the RR device is only responsible for control plane route reflection and does not forward traffic.

正解:

Question No : 12
Which of the following descriptions about MPLS optimization solutions is incorrect?

A.It is recommended to deploy a bidirectional tunnel with the same path, which is convenient for maintenance and more reliable for tunnel BFD detection.
B.When optimizing the path calculation, give priority to the creation of high-priority tunnels. High-priority tunnels can preempt low-priority tunnel resources.
C.RSVP-TE, SR-TE, and LDP tunnels can all be optimized
D.When multiple load-sharing tunnels are deployed between two PE nodes, it is recommended to deploy a separate group.
