Explanation:
A flow monitor is essentially a NetFlow cache. The Flow Monitor has two major components the Flow Record and the Flow Exporter. The flow monitor
can track both ingress and egress information. The flow record contains what information being tracked by NetFlow (i.e. IP address, ports, protocol...).
The Flow exporter describes the NetFlow export. Flow monitors may be used to track IPv4 traffic, IPv6 traffic, multicast or unicast, MPLS, bridged
traffic. Multiple Flow monitors can be created and attached to a specific physical or logical interface. Flow monitors can also include packet sampling
information if sampling is required.

QUESTION 109
What are three benefits of GLBP? (Choose three.)
A. GLBP supports up to eight virtual forwarders per GLBP group.
B. GLBP supports clear text and MD5 password authentication between GLBP group members.
C. GLBP is an open source standardized protocol that can be used with multiple vendors.
D. GLBP supports up to 1024 virtual routers.
E. GLBP can load share traffic across a maximum of four routers.
F. GLBP elects two AVGs and two standby AVGs for redundancy.
Correct Answer: BDE
Section: (none)
Explanation

Explanation:
Load Sharing
You can configure GLBP in such a way that traffic from LAN clients can be shared by multiple routers, thereby sharing the traffic load more equitably
among available routers. Multiple Virtual Routers GLBP supports up to 1024 virtual routers (GLBP groups) on each physical interface of a router, and up
to four virtual forwarders per group.
Preemption
The redundancy scheme of GLBP enables you to preempt an active virtual gateway with a higher priority backup virtual gateway that has become
available. Forwarder preemption works in a similar way, except that forwarder preemption uses weighting instead of priority and is enabled by default.
Authentication
You can use a simple text password authentication scheme between GLBP group members to detect configuration errors. A router within a GLBP group
with a different authentication string than other routers will be ignored by other group members.
GLBP Authentication
GLBP has three authentication types:
MD5 authentication
Plain text authentication
No authentication
