You are considering using IPMP and Link Aggregation. Which two statements are true about these
technologies?
A.
IPMP requires all interfaces to support the same bit rate.
B.
Both technologies can increase outbound bandwidth.
C.
Link Aggregation does not offer link failure protection.
D.
Link Aggregation requires all interfaces to support the same bit rate.
E.
IPMP supports load spreading across all interfaces for inbound traffic
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
Incorrect:
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 link
B and D are correct.
E not: IPMP support load spreading across all interface for OUTBOUND (not inbound) traffic
B D

IPMP improves overall network performance by automatically spreading out outbound network traffic across the set of interfaces in the IPMP group. This process is called outbound load spreading. The system also indirectly controls inbound load spreading by performing source address selection for packets whose IP source address was not specified by the application. However, if an application has explicitly chosen an IP source address, then the system does not vary that source address.
