QUESTION: 9

The following is Engineer A's understanding of LVS cluster, the correct one is.

The commonly used scheduling strategies of LVS are: round-robin scheduling, weighted round-robin scheduling, minimum number of connections, fast connection response priority, etc.
LVS is a virtual server cluster, working at the seventh layer of the network system, using IP load balancing technology and content-based request distribution technology
LVS cluster is mainly composed of three parts: load scheduler, server pool (sefvertboilke er), shared storage (shared storage)
LVS has three working modes: LVS Idiot LVSDR (direct routing), LVS-TUN (tunnel)

Answer(s): A,C,D

QUESTION: 12

The following is the error of Engineer A's rationale for IVsS load balancing technology.

The advantage of LVS/DR is that the server can run any Vent TCP/IP operating system, it only needs one IP address to configure in the server group to use a private IP address
LVS/NAT is one of the most efficient way. All Realservers only need to point their gateway to DIYetp and Dretor can also be a RealServer
In LVS/DR mode, the scheduler dynamically selects RTVU not to dare or encapsulate IP packets according to the load of each server, but instead changes the MAC address of the data frame to the HAC address of the server.
In LVS/DR mode, Diretor and Realserver must be physically connected by a network card through an uninterrupted LAN
