You work as a network engineer for. You study the exhibit carefully. Based on the output of the show command，
what can you determine regarding EIGRP routing being performed by the switch？ （）
Exhibit：
A.There are 20 neighbors in the EIGRP neigbor table.
B.EIGRP is running normally and receiving IPv4 routing updates.
C.The switch has not established any neighbor relationships. Further network testing and troubleshooting must be performed to determine the cause of the problem.
D.EIGRP status cannot be determined. The command show ip eigrp topology would determine the routing protocol status.

Exhibit：
A.VLAN 30 is not operational due to the fact that there are no packet or byte counts indicated.
B.The IP Cisco Express Forwarding configuration is capable of supporting IPv6.
C.Cisco Express Forwarding load balancing has been disabled.
D.SVI VLAN 30 connects directly to the 10.1.30.0/24 network due to a valid glean adjacency.
You work as a network engineer for. You study the exhibit carefully. Based on the configuration
shown，
which two statements are correct regarding this Layer 3 security configuration example？ （）
Exhibit：
A.Source IP and MAC filtering on VLANs 10 and 11 will occur.
B.The switch will drop the configured MAC and IP address source bindings and forward all other traffic.
C.DHCP snooping will be automatically enabled on the access VLANs.
D.IP Source Guard is enabled.
E.Static IP source binding can only be configured on a routed port.
You work as a network engineer for. You study the exhibit carefully. From the configuration sample shown of a Cisco Catalyst 3560 Series Switch，
what can you determine regarding Layer 3 routing functionality of the interface？（）
Exhibit：
A.The interface is configured correctly for Layer 3 routing capabilities.
B.The interface needs an additional configuration entry to enable IP routing protocols.
C.The interface subcommand ip routing is required to enable IP routing on the interface.
D.An SVI interface is required to enable IP routing for network 192.20.135.0.
A new floor has been added to the enterprise campus network， providing client access for desktop PCs， laptops， and IP phones for employees and guests. During verification， a few desktop PCs have limited corporate access but not Internet access. Most other desktop PCs， all laptops， and IP phones are working correctly. Additional information indicates that the desktop PCs are obtaining IP host addresses from the DHCP server， which is intended for only the IP phones.
Where should troubleshooting about this connectivity issue be focused？（）
A.DNS
B.first-hop redundancy protocol
C.DHCP server and options
D.VLAN mapping
E.client network configuration
F.routing protocols
A new building has been added to the enterprise campus network， providing client access for desktop PCs， laptops， and IP phones for employees and guests. During verification， only a few laptops using
wireless are reported to have problems， while other desktops， IP phones， and most other wireless laptops are fully operational. Additional information received about the problem indicates that， while the problematic wireless laptops cannot reach internal corporate websites， they can reach the Internet.
Where should troubleshooting about this connectivity issue be focused？（）
A.client network configuration
B.VLAN mapping
C.routing protocols
D.first-hop redundancy protocol
You work as a network engineer for. You study the exhibit carefully. You have configured an interface to be an SVI for Layer 3 routing capabilities. Assuming that all VLANs have been correctly configured and based on the configuration example shown，
what can be determined？ （）
Exhibit：
A.Interface gigabitethernet0/2 will be excluded from Layer 2 switching and enabled for Layer 3 routing.
B.The interface is missing IP configuration parameters； therefore， it will only function at Layer 2.
C.The command switchport autostate exclude should be entered in global configuration mode， not sub-interface mode， to enable a Layer 2 port to be configured for Layer 3 routing.
D.The configured port is excluded in the calculation of the status of the SVI.
You have configured a Cisco Catalyst switch to perform Layer 3 routing via an SVI and have
assigned that interface to VLAN 20. To check the status of the SVI， you issue the show interfaces vlan 20 command at the CLI prompt. You see from the output display that the interface is in an "up/up" state.
What must be true in an SVI configuration to bring the VLAN and line protocol up？（）
A.The port must be physically connected to another Layer 3 device.
B.At least one port in VLAN 20 must be active.
C.The Layer 3 routing protocol must be operational and receiving routing updates from neighboring peer devices.
D.Because this is a virtual interface， the operational status will always be in an "up/up" state.
