質問 1：
About the description of the Huawei SDN solution Overaly technology VXLAN protocol, which is wrong?
A. VXLAN is built on UDP technology
B. VXLAN uses ECMP of Underlay network to bring higher network forwarding performance
C. VXLAN expands the subnet to 16M and supports multi-tenancy
D. The endpoint of the VXLAN tunnel encapsulation is called VNI.
正解：D
質問 2：
On the Huawei SDN solution vDC active-standby disaster recovery-active and standby egress scenarios, an active/standby external network can support multiple outlets to form one active and multiple standby.
A. False
B. True
正解：A
質問 3：
In a Huawei SDN solution, an iBGP neighbor and an eBGP neighbor can exist simultaneously in the BGP instance where the EVPN is deployed.
A. False
B. True
正解：A
質問 4：
Which of the following description about the design of the data center network security solution is correct?
A. IDS is usually deployed side by side in the data center, because it is considered to avoid single point of failure, and it is also considered that the direct path deployment will cause all traffic to be detected by the device and cause network delay.
B. The degree of network security in the data center depends mainly on the performance of the equipment and the security capabilities of the vendors. Therefore, careful consideration should be given to product procurement.
C. Because the firewall is a comprehensive device that combines IPS and anti-virus capabilities, you can replace all IPS devices with NGFW to save costs.
D. In order to meet the requirements of Level 3 of information security, all types of security devices must be deployed. For example, NGFW, Anti-DDoS, IPS, CIS, LogCenter, UMA, etc. must be deployed.
正解：A
質問 5：
In the Huawei SDN solution, ahout the reliability analysis of the Network Overlay centralized gateway (CE12800 as the gateway role), which description of following is incorrect?
A. Gateway multiple-active deployment, with the same gateway address and different tunnel endpoint addresses.
B. Stand-alone/stacking devices independently make VXLAN gateways. Specifications: 4K tenants, high reliability.
C. Multiple sets of multiple-active gateways are deployed to add independent gateway devices, but the forwarding capacity and reliability within a single set of gateways are unchanged.
D. Two independent devices establish VRRP groups and have independent tunnel endpoint addresses with high reliability.
