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.
A.The best match of the ACL entries will be used for granularity of control.
B.They use source IP information for matching operations.
C.They use source and destination IP information for matching operations.
D.They use source IP information along with protocol-type information for finer granularity of control.
A.Enable the switch to participate in routing updates from external devices with the router command in global configuration mode.
B.Enter the no switchport command to disable Layer 2 functionality at the interface level.
C.Each port participating in routing of Layer 3 packets must have an IP routing protocol assigned on aperinterface level.
D.Routing is enabled by default on a multilayer switch， so the port can become a Layer 3 routing interface by assigning the appropriate IP address and subnet information.
A.ease of IP address assignment versus use of external routers
B.redundancy from trunking between distribution layer switches
C.provides first-hop redundancy to clients
D.allows inter-VLAN communication without requiring complexity of routing protocols
You work as a network engineer for . You study the exhibit carefully.
What best describes the Cisco IOS IP SLA command and output in the exhibit？（）
A.verifies which operation types have been enabled for IP SLA source
B.verifies which operation types have been enabled for IP SLA responder
C.verifies which operation types are supported in software
D.verifies enabled operation types that are not running
You work as a network engineer for. You study the exhibit carefully. Which of these is true based upon the output shown in the command？（）
Exhibit：
A.The port has security enabled and has shut down due to a security violation.
B.The port is operational and has reached its configured maximum allowed number of MAC addresses.
C.The port will allow access for 11 MAC addresses in addition to the 3 configured MAC addresses.
D.If the number of devices attempting to access the port exceeds 11， the port will shut down for 20 minutes， as configured.
A.PACLs can be applied in the inbound or outbound direction of a Layer 2 physical interface.
B.At Layer 2， a MAC address PACL will take precedence over any existing Layer 3 PACL.
C.When you apply a port ACL to a trunk port， the ACL filters traffic on all VLANs present on the trunk port.
D.PACLs are not supported on EtherChannel interfaces.
A.Configure the private VLAN port parameters.
B.Configure and map the secondary VLAN to the primary VLAN.
C.Disable IGMP snooping.
D.Set the VTP mode to transparent.
