Explanation

B: Link aggregations provide high availability and higher throughput by aggregating multiple interfaces at the MAC layer. IP Multipathing (IPMP) provides features such as higher availability at the IP layer. Both IPMP and Link Aggregation are based on the grouping of network interfaces, and some of their features overlap, such as higher availability. These technologies are however implemented at different layers of the stack, and have different strengths and weaknesses. E: Internet Protocol Network Multipathing (IPMP) provides fault-tolerance and load balancing across multiple network interface cards. By using IPMP, you can configure one or more interfaces into an IP multipathing group. After configuring IPMP, the system automatically monitors the interfaces in the IPMP group for failure. If an interface in the group fails or is removed for maintenance, IPMP automatically migrates, or fails over, the failed interface's IP addresses Not A: The same (non-null) character string IPMP group name identifies all interfaces in the group. You can place interfaces from NICs of different speeds within the same IPMP group, as long as the NICs are of the same type. Not C:If LACP (Link Aggregation Control Protocol) cannot aggregate all the ports that are compatible (for example, the remote system might have more restrictive hardware limitations), then all the ports that cannot be actively included in the channel are put in hot standby state and are used only if one of the channeled ports fails. Not D: MP is built into Oracle Solaris and does not require any special hardware. Any interface that is supported by Oracle Solaris can be used with IPMP. However, IPMP does impose the following requirements on your network configuration and topology: /All interfaces in an IPMP group must have unique MAC addresses. / All interfaces in an IPMP group must be of the same media type. / All interfaces in an IPMP group must be on the same IP
