Example Questions

For security reasons, the IT manager has prohibited users from dynamically establishing trunks with their associated upstream switch. Which two actions can prevent interface trunking? (Choose two.) Which gateway role is responsible for answering ARP requests for the virtual IP address in GLBP? Which statement about LLDP-MED is true? Which statement about the UDLD protocol is true? After reviewing UDLD status on switch ports, an engineer notices that the." Which statement describes what this indicates about the status of the port? A new network that consists of several switches has been connected together via trunking interfaces. If all switches currently have the default VTP domain name "null", which statement describes what happens when a domain name is configured on one of the switches? Which authentication service is needed to configure 802.1x? Which option lists the modes that are available for configuring UDLD on a Cisco switch? What does the command vlan dot1q tag native accomplish when configured under global configuration? After the implementation of several different types of switches from different vendors, a network engineer notices that directly connected devices that use Cisco Discovery Protocol are not visible. Which vendor-neutral protocol could be used to resolve this issue? In a Cisco switch, what is the default period of time after which a MAC address ages out and is discarded? After port security is deployed throughout an enterprise campus, the network team has been overwhelmed with port reset requests. They decide to configure the network to automate the process of re-enabling user ports. Which command accomplishes this task? When two MST instances (MST 1 and MST 2) are created on a switch, what is the total number of spanning-tree instances running on the switch? After UDLD is implemented, a Network Administrator noticed that one port stops receiving UDLD packets. This port continues to reestablish until after eight failed retries. The port then transitions into the errdisable state. Which option describes what causes the port to go into the errdisable state? While working in the core network building, a technician accidently bumps the fiber connection between two core switches and damages one of the pairs of fiber. As designed, the link was placed into a non-forwarding state due to a fault with UDLD. After the damaged cable was replaced, the link did not recover. What solution allows the network switch to automatically recover from such an issue? Which action allows a network engineer to limit a default VLAN from being propagated across all trunks? Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This command is configured globally: monitor session 2 filter vlan 1 - 8, 39, 52 What is the result of the implemented command? Which statement about the use of SDM templates in a Cisco switch is true? An EtherChannel bundle has been established between a Cisco switch and a corporate web server. The network administrator noticed that only one of the EtherChannel links is being utilized to reach the web server. What should be done on the Cisco switch to allow for better EtherChannel utilization to the corporate web server? Which option lists the information that is contained in a Cisco Discovery Protocol advertisement? A network engineer configured a fault-tolerance link on Gigabit Ethernet links G0/1, G0/2, G0/3, and G0/4 between two switches using Ethernet port-channel. Which action allows interface G0/1 to always actively forward traffic in the port-channel? When IP Source Guard with source IP filtering is enabled on an interface, which feature must be enabled on the access VLAN for that interface? Which First Hop Redundancy Protocol is an IEEE Standard? Which option is a possible cause for an errdisabled interface? A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery Protocol, but it has several routing neighbor relationships. What would cause the output to show only the single neighbor? What is the size of the VLAN field inside an 802.1q frame? What is the function of NSF? After the recent upgrade of the switching infrastructure, the network engineer notices that the port roles that were once "blocking" are now defined as "alternate" and "backup." What is the reason for this change? Which VLAN range is eligible to be pruned when a network engineer enables VTP pruning on a switch? An administrator recently configured all ports for rapid transition using PortFast. After testing, it has been determined that several ports are not transitioning as they should. What is the reason for this? Which statement describes what happens when a port configured with root guard receives a superior BPDU? The network manager has requested that several new VLANs (VLAN 10, 20, and 30) are allowed to traverse the switch trunk interface. After the command switchport trunk allowed vlan 10,20,30 is issued, all other existing VLANs no longer pass traffic over the trunk. What is the root cause of the problem? While troubleshooting a network outage, a network engineer discovered an unusually high level of broadcast traffic coming from one of the switch interfaces. Which option decreases consumption of bandwidth used by broadcast traffic? A switch is added into the production network to increase port capacity. A network engineer is configuring the switch for DHCP snooping and IP Source Guard, but is unable to configure ip verify source under several of the interfaces. Which option is the cause of the problem? What happens on a Cisco switch that runs Cisco IOS when an RSTP-configured switch receives 802.1d BPDU? Which command would a network engineer apply to error-disable a switchport when a packet- storm is detected? Which feature describes MAC addresses that are dynamically learned or manually configured, stored in the address table, and added to the running configuration? A server with a statically assigned IP address is attached to a switch that is provisioned for DHCP snooping. For more protection against malicious attacks, the network team is considering enabling dynamic ARP inspection alongside DHCP snooping. Which solution ensures that the server maintains network reachability in the future? Which command correctly configures standby tracking for group 1 using the default decrement priority value? A network engineer must set the load balance method on an existing port channel. Which action must be done to apply a new load balancing method? Which statement about Cisco devices learning about each other through Cisco Discovery Protocol is true? A Cisco Catalyst switch that is prone to reboots continues to rebuild the DHCP snooping database. What is the solution to avoid the snooping database from being rebuilt after every device reboot? What is the default value for the errdisable recovery interval in a Cisco switch? Which feature must be enabled to eliminate the broadcasting of all unknown traffic to switches that are not participating in the specific VLAN? Which private VLAN access port belongs to the primary VLAN and can communicate with all interfaces, including the community and isolated host ports? What is the maximum number of 10 Gigabit Ethernet connections that can be utilized in an EtherChannel for the virtual switch link? For client server failover purposes, the application server team has indicated that they must not have the standard 30 second delay before their switchport enters a forwarding state. For their disaster recovery feature to operate successfully, they require the switchport to enter a forwarding state immediately. Which spanning-tree feature satisfies this requirement? Which type of information does the DHCP snooping binding database contain? Which statement describes what happens if all VSL connections between the virtual switch members are lost? A DHCP configured router is connected directly to a switch that has been provisioned with DHCP snooping. IP Source Guard with the ip verify source port-security command is configured under the interfaces that connect to all DHCP clients on the switch. However, clients are not receiving an IP address via the DHCP server. Which option is the cause of this issue?
