单项选择题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.

单项选择题You work as a network engineer for . You study the exhibit carefully. Based upon the output shown，  what can you determine？（）  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.

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.

单项选择题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.

单项选择题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
