QUESTION 203 When a Layer 2 EtherChannel is configured, which statement about placement of the IP address is true?. The IP address is placed on the highest numbered member port. The IP address is placed on the port-channel logical interface. The IP address is placed on the lowest numbered member port. The IP address is assigned via DHCP only.

QUESTION 204 Which option is valid for EtherChannel load balancing?. source MAC address and source IP address. destination MAC address and destination IP address. source MAC address and destination IP address. source MAC address and destination MAC address.

QUESTION 205 Refer to the exhibit. An engineer is configuring EtherChannel between two switches and notices the console message on switch 2. Based on the output, which option describes the reason for this error?. Switch 1 does not have enough member ports configured. Switch 2 has too many member ports configured. The port channel interface numbers do not match. The EtherChannel protocols do not match.

QUESTION 206 Refer to the exhibit. DSW1 should share the same MST region with switch DSW2. Which statement is true?. Configure DSW1 with the same version number, and VLAN-to-instance mapping as shown on DSW2. DSW2 uses the VTP server mode to automatically propagate the MST configuration to DSW1. DSW1 automatically inherits MST configuration from DSW2 because they have the same domain name. Configure DSW1 with the same region name, revision number, and VLAN-to-instance mapping as shown on DSW2. DSW1 is in VTP client mode with a lower configuration revision number, therefore, it automatically inherits MST configuration from DW2.

QUESTION 214 Which two statements about HSRP, GLBP, and VRRP are true? (Choose two.). HSRP is the preferred protocol to be used on multivendor environments. VRRP has one master router, one standby router, and many listening routers. GLBP allows for a maximum of four MAC addresses per group. HSRP supports up to 255 groups on the same switch or router. VRRP is a Cisco proprietary protocol.

QUESTION 215 Refer to the exhibit. Which option is the most likely explanation of the duplicate address message logged?. spanning-tree loop. HSRP misconfiguration. a PC with IP of 10.10.1.1. a hardware problem.

QUESTION 217 Refer to the exhibit. A network engineer changes the default native VLAN to VLAN 999. After applying the settings on the uplinks to the core switches, the switch control traffic, such as CDP and VTP, is no longer working. The standard configuration is used for each uplink. What is wrong with the configuration?. The interface is administratively down. The encapsulation type is incorrect. The switchport mode trunk command should be first in the output. The native VLAN is not present on the trunk. The control traffic must be manually enabled on the new native VLAN.

QUESTION 218 Which two options are two results of using the command spanning-tree vlan 50 root primary within a spanning-tree network under global configuration? (Choose two.). Spanning tree determines the priority of the current root for VLAN 50 and reduces the priority of the local switch to a lower valu. The priority value for VLAN 50 is set to 4094 on the root while the local switch priority is set to 32768. The spanning-tree timers are reduced to improve the convergence time for VLAN 50. All ports that are configured on the current switch with VLAN 50 transition to designated ports. The switchport that is configured for VLAN 50 is the primary connection to the spanning-tree root switch.

QUESTION 219 An access switch at a remote location is connected to the spanning-tree root with redundant uplinks. A network engineer notices that there are issues with the physical cabling of the current root port. The engineer decides to force the secondary link to be the desired forwarding root port. Which action accomplishes this task?. Change the link-type to point-to-point. Enable Rapid Spanning Tree to converge using the secondary link. Adjust the secondary link to have a lower priority than the primary link. Apply a BPDU filter on the primary interface of the remote switches.

QUESTION 220 A network engineer wants to make sure that an access switch will never become a Spanning Tree root for VLAN 5. What action will accomplish this task?. adjust STP priority to the maximum value. disable STP globally. apply root guard to all outgoing neighbor interfaces. enable MSTP and use a different revision number than all other switches.

QUESTION 221 What action should a network administrator take to enable VTP pruning on an entire management domain?. Enable VTP pruning on any client switch in the domain. Enable VTP pruning on every switch in the domain. Enable VTP pruning on any switch in the management domain. Enable VTP pruning on a VTP server in the management domain.

QUESTION 222 Refer to the exhibit. BPDUGuard is enabled on both ports of SwitchA. Initially, LinkA is connected and forwarding traffic. A new LinkB is then attached between SwitchA and HubA. Which two statements about the possible result of attaching the second link are true? (Choose two. The switch port attached to LinkB does not transition to up. One or both of the two switch ports attached to the hub goes into the err-disabled state when a BPDU is received. Both switch ports attached to the hub transitions to the blocking state. A heavy traffic load could cause BPDU transmissions to be blocked and leave a switching loop. The switch port attached to LinkA immediately transitions to the blocking state.

QUESTION 223 What is the effect of configuring the following command on a switch? Switch(config) # spanning-tree portfast bpdufilter default. If BPDUs are received by a port configured for PortFast, then PortFast is disabled and the BPDUs are processed normally. If BPDUs are received by a port configured for PortFast, they are ignored and none are sent. If BPDUs are received by a port configured for PortFast, the port transitions to the forwarding state. The command enables BPDU filtering on all ports regardless of whether they are configured for BPDU filtering at the interface level.

QUESTION 224 Which protocol will enable a group of routers to form a single virtual router and will use the real IP address of a router as the gateway address. Proxy ARP. HSRP. IRDP. VRRP. GLBP.

QUESTION 225 Which two statements are true about recommended practices that are to be used in a local VLAN solution design where layer 2 traffic is to be kept to a minimum? (Choose two.). Routing should occur at the access layer if voice VLANs are utilized. Otherwise, routing should occur at the distribution layer. Routing may be performed at all layers but is most commonly done at the core and distribution layers. Routing should not be performed between VLANs located on separate switches. VLANs should be local to a switc. VLANs should be localized to a single switch unless voice VLANs are being utilized.

QUESTION 226 What two things occur when an RSTP edge port receives a BPDU? (Choose two.). The port immediately transitions to the forwarding state. The switch generates a Topology Change Notification BPDU. The port immediately transitions to the err-disable state. The port becomes a normal STP switch port.

QUESTION 227 How does VTP pruning enhance network bandwidth?. by restricting unicast traffic across VTP domains. by reducing unnecessary flooding of traffic to inactive VLANs. by limiting the spreading of VLAN information. by disabling periodic VTP updates.

QUESTION 228 In the hardware address 0000.0c07.ac0a, what does 07.ac represent?. vendor code. HSRP group number. HSRP router number. HSRP well-known physical MAC address. HSRP well-known virtual MAC address.

QUESTION 229 Which statement is true about RSTP topology changes?. Any change in the state of the port generates a TC BPDU. Only nonedge ports moving to the forwarding state generate a TC BPDU. If either an edge port or a nonedge port moves to a block state, then a TC BPDU is generated. Only edge ports moving to the blocking state generate a TC BPDU. Any loss of connectivity generates a TC BPDU.

QUESTION 230 Refer to the exhibit. Based on the debug output, which three statements about HSRP are true? (Choose three.). The final active router is the router with IP address 172.16.11.111. The router with IP address 172.16.11.111 has preempt configured. The priority of the router with IP address 172.16.11.112 is preferred over the router with IP address 172.16.11.111. The IP address 172.16.11.115 is the virtual HSRP IP address. The router with IP address 172.16.11.112 has nonpreempt configured. The router with IP address 172.16.11.112 is using default HSRP priority.
