VLAN pools support two VLAN assignment algorithms: even and hash. Drag the advantages and disadvantages to the two algorithms.
A. Even Algorithm – Advantages
B. Even Algorithm – Disadvantages
C. Hash Algorithm – Advantages
D. Hash Algorithm – Disadvantages
Question # 2
When receiving a packet, a Huawei router matches the packet against ACL rules. The default ACL matching order used by the Huawei router is:
A. Permit first, then deny
B. Deny first, then permit
C. Longest prefix match first
D. Random order
Question # 3
FD for OSPF is deployed on a directly connected link. If the physical link is disconnected,Drag the following BFD processes to the corresponding sequence numbers.
A. Detect link failure
B. Notify OSPF of neighbor down
C. Tear down adjacency
D. Forward traffic over alternate path
Question # 4
When deploying BFD, you need to adjust some parameters so that it can better detect the network status. Which of the following statements is false about BFD optimization?
A. After a high priority is configured for BFD packets, BFD packets are preferentially forwarded.
B. To quickly learn about the network status and performance requirements, you can set the interval for sending BFD packets to the minimum value.
C. On a live network, some devices switch traffic only when a BFD session changes to the Up state. If a routing protocol goes Up later than an interface, no route is available for switching traffic back, leading to traffic loss. To resolve this issue, configure a delay to compensate for the time difference caused when the routing protocol goes Up later than the interface.
D. If a BFD session flaps, master/backup switchovers are frequently performed on the application associated with the BFD session. To prevent this, set the WTR time of the BFD session.
