   Your OSPF network consists of a mix of 1GbE and 10GbE interfaces. By default, all interfaces have the same cost in your OSPF network. You are asked to ensure that the 10GbE interfaces are more preferred when available. In this scenario, which two statements would accomplish this behavior? (Choose two.)

   • AYou should define the reference bandwidth as 10G, which will assign the 1GbE interfaces a higher cost.
   • BYou should manually assign the interface metric for each 10GbE interface to be higher than the 1GbE interfaces in your OSPF network.
   • CYou should define the reference bandwidth as 1G, which will assign the 1GbE interfaces a higher cost.
   • DYou should manually assign the interface metric for each 1GbE interface to be higher than the 10GbE interfaces in your OSPF network.

   You have two multicast receivers connected to the same VLAN. You notice that the switch that they are connected to is forwarding multicast traffic out of all the ports in the same VLAN, instead of just the two ports for the connected multicast receivers. In this scenario, what would you configure to optimize multicast forwarding?

   • Apromiscuous mode
   • Bspanning tree
   • CIGMP snooping
   • DIRB interface

   You are implementing an EVPN-VXLAN edge-routed bridging design using Layer 3 gateway operations. In this scenario, which statement is correct?

   • AEach distribution switch has unique IP addresses for IRB interfaces; routing protocols run on IRB interfaces.
   • BDistribution switches share the same anycast IP addresses for IRB interfaces; routing occurs at the distribution layer.
   • COnly core switches have IRB interfaces; all Layer 3 routing happens in the core.
   • DIRB interfaces are disabled; all routing happens through external routers only.

   Which two statements correctly describe how EX Series switches use captive portal for Layer 2 authentication? (Choose two.)

   • AThe captive portal is the default Layer 2 authentication method that is applied before other methods such as 802.1X or MAC RADIUS.
   • BThe captive portal authentication allowlist works for devices that do not have HTTP capabilities.
   • CThe captive portal is configured on Layer 3 interfaces and does not participate in Layer 2 authentication on EX Series switches.
   • DThe captive portal is used as a fallback mechanism for clients that fail 802.1X or MAC RADIUS authentication.
