You are performing an in-service software upgrade (ISSU) on an QFX5100 Series device.
Which two statements are correct in this scenario? (Choose two.)
Referring to the exhibit, each leaf node is a QFX5100 acting as a VXLAN Layer 2 Gateway using EVPN signaling. Leaf 2 and Leaf 3 are both attached to the same EVPN Ethernet segment. Leaf 2 has been elected the designated forwarder for VLAN 200 on that Ethernet segment.
In this scenario, which two actions will Leaf 1 perform with the broadcast Ethernet frame received from Host A? (Choose two.)
You are deploying an IP Fabric in your new data center. You need to ensure that your servers have multiple active/active links for redundancy and load balancing.
What are two methods to accomplish this goal? (Choose two.)
NOT A because EVPN is specifically designed to handle multi-homed access redundancy, and mobility, and load-balancing is possible. I would not choose this though because EVPN is primarily a DCI protocol -- for interconnecting datacenters -- and is not typically considered an access layer protocol facing the servers. It is possible to use EVPN inside a single datacenter, in which case it would be used between the access switches and the distribution/core switches. In the spirit of the question however, this does not face the servers directly so I exclude it.
B because MSTP allows for multiple spanning trees, which allows for use of all inter-switch links by, for example, aggregating VLANs into spanning trees -- eg: VLANs 1-100 in one tree, 101-200 in another. One spanning tree is active on a given link, the other is inactive. In this way load-balancing is achieved. In case of link failure, all traffic will fall to the remaining link(s).
C because MC-LAG allows for link aggregation across multiple chasses -> permits load-balancing and provides redundancy.
NOT D because PIM-SM is a control-plane signaling protocol for multicast which enables routers to join and prune their membership to given multicast distribution trees. It has little directly to do with the redundancy and load-balancing of (multicast) traffic receivers.
VMs on Server-1 and Server-2 are on the same Layer 2 domain within a VCF and are sending traffic to each other.
Referring to the exhibit, which three criteria are used when load-balancing traffic? (Choose three.)
Which statement is true for an IP Fabric to be called a Clos IP Fabric?
