Layer 3 networks support load balancing.

Layer 2 networks are susceptible to loops.

Layer 2 networks only support a single broadcast domain.

IP fabrics are better suited to smaller networks where scale is less important.

Layer 3 networks support load balancing.

It is the only option to provide reachability between servers that reside in the same network segment in a data center.

BGP provides the control plane within the overlay network.

An encapsulation of the original packet is required to transport the packet across the network.

OSPF provides the control plane within the overlay network.

Next hop IP address 172.25.20.200 will be preferred.

Next hop IP address 172.25.20.254 will be preferred.

Neither next hop will be preferred.

Next hop IP address 172.25.20.200 will be preferred.

Both next hops will be preferred.

When using spine and leaf fabric architectures, what is the role of each device? (Choose two.)

Spine nodes are used for transit to other leaf nodes.

Leaf nodes are used for host connectivity.

Spine nodes are used for host connectivity.

Spine nodes are used for transit to other leaf nodes.

Leaf nodes are used for traffic to other leafs.

Leaf nodes are used for host connectivity.

You are troubleshooting a downed BGP session. Referring to the exhibit, what is the cause of the problem?

The TCP session between the peers has not been established.

The UDP session between the peers has not been established.

The local peer has sent an Open message but not received one from the remote peer.

The TCP session between the peers has not been established.

The local peer has sent an Update message but not received one from the remote peer.

Exhibit: R2 received an OSPF update from R1, and it received the same update from R3.Referring to the exhibit, what will R2 do?

R2 does nothing with R3's update.

R2 acknowledges R3 and discards it.

What is the definition of a trunk interface on a switch?

An interface that carries multiple VLANs.

An interface that carries high bandwidth.

An interface that connects directly to powerful servers.

An interface that carries excess traffic.

Exhibit: Referring to the exhibit, which behavior does this configuration enable on the ge-0/0/1.0 interface?

This configuration enables a MAC address learned on the interface to be persistently retained in the Ethernet-switching table, even after a reboot.

This configuration enables the device to place a MAC address that persistently causes network errors into a special protected VLAN.

This configuration enables the device to shut down the interface when a particular MAC address persistently sends broadcast traffic.

This configuration enables the interface to learn and remember MAC addresses, until the device is rebooted.

You are creating an IP fabric underlay and want to use OSPF as your routing protocol.In this scenario, which statement is correct?

Interface speeds should be the same throughout the fabric to ensure that all links are utilized.

All leaf devices must be configured in separate OSPF areas.

All leaf and spine devices must be the same model to ensure the proper load-balancing behavior.

Interface speeds should be the same throughout the fabric to ensure that all links are utilized.

All spine devices must use the same router ID.

Which statement about switches is correct?

Each port is a member of VLAN 2 by default.

Every port is in a unique collision domain.

Each port is in a unique broadcast domain by default.

All ports reside in the same collision domain.

By default, which two statements are correct about BGP advertisements? (Choose two.)

BGP peers advertise routes received from EBGP peers to other IBGP peers.

BGP peers advertise routes received from IBGP peers to other IBGP peers.

BGP peers advertise routes from EBGP peers to other IBGP peers using its own address as the next hop.

BGP peers advertise routes from IBGP peers to EBGP peers using its own address as the next hop.
