LACP will form a 200-Mb/s channel between the switches
Which two items are benefits of implementing local VLANs within the Enterprise Architecture? (Choose two.) A single VLAN can e xtend further than its associated distribution-layer switch. Failures at Layer 2 are isolated to a small s ubset of users. High availability is made possible because local VLAN traffic on access switches can now be passed directly to the core switc hes across an alternate Layer 3 path. Layer 3 routing between VLANs can now be applied at the access layer. Local VLANs are limited to the access and distribution layer
Which two statements describe Cisco best practices for VLAN design? (Choose two.) Local VLANs should extend no further than the local core router. Local VLANs should extend no further than the local distribution layer switch. Local VLANs eliminate the need for redundant access to distribution layer links. Local VLANs provide a simple design that is easy to troubleshoot

One switch in a Layer 2 s witched spanning-tree domain is converted to PVRST+ using the spanning-tree mode rapid-pvst global configuration mode command. The remaining switches are running PVST+. What is the effec t on the spanning-tree operation? Spanning tree is effectively disabled in the network. The PVRST+ switch forwards 802.1D BPDUs, but does not participate as a node in a ny spanning tree. All switches default to one 802.1D spanning tree for all VLANs. The PVSRT+ reverts to PVST+ to interoperate with the PVST+ switches
Refer to the exhibit. What implementation of spanning tree best describes the spanning-tree operational mode of the switch? IEEE 802.1D
IEEE 802.w
IEEE 802.1s
PVRST+

DLS1 is the root bridge for instance 1. Interface Fa0/12 will move into the errdisable state if a BPDU is received. Interfaces Fa0/1 through Fa0/6 are trunk ports
Which three parameters should match all switches within an MST region? (Choose three.) port costs on trunk ports configuration name revision number
trunk encapsulation method bridge priority VLAN-to-instance mappings
Users complain that they lost connectivity to all resources in the network. A network administrator suspects the presence of a bridging loop as a root cause of the problem. Which two actions will determine the existence of the bridging loop? (Choose two.) Confirm MAC port security is enabled on all access switches. Check the port utilization on devices and look for abnormal values. Verify that the management VLAN is properly configured on all root bridges. Capture the traffic on the s aturated link and verify if duplicate packets are seen. Ensure that the root guard and loop guard are properly configured on all distribution links
Refer to the exhibit. Switch SW1 is receiving traffic from SW2. However, SW2 is not receiving traffic from SW1. W hich STP feature should be implemented to prevent inadvertent loops in the network? UDLD PortFast BPDU guard BPDU filtering
Which interfaces should loop guard be enabled on? root ports designated ports root port and alternate ports ports configured with PortFast root port and ports configured with PortFast
What will happen when a BPDU is received on a loop guard port that is i n a loop-inconsistent state? The port will transition to blocking state. The port will transition to forwarding state a utomatically. The port will be disabled and the administrator must re-enable it manually. The port will transition to the appropriate state as determined by the normal function of the spanning tree
Refer to the exhibit. STP is enabled on all s witches in the network. The port on s witch A that connects to switch B is half duplex. The port on switch B t hat connects to switch A is full duplex. What are three problems that this sc enario could create? (Choose three.) Switch B will become the root switch. Switch B may unblock its port to switch C, thereby creating a loop. Switch A is performing carrier sense and collision detection, and switch B is not. Autonegotiation results in both switch A and s witch B failing to perform carrier sense. BPDUs may not successfully negotiate port states on the link between switch A and switch B. Spanning tree will keep re-calculating, thereby consuming all the CPU normally used for traffic
Refer to the exhibit. STP is configured on all s witches in the network. Recently, the user on workstation A lost connectivity to the rest of the network. At the same time, the administrator received the console message: %SPANTREE-2-RX_PORTFAST:Received BPDU on PortFast enable port.Disabling 2/1 What is the cause of the problem? STP PortFast feature has been disabled on port 2/1. STP PortFast feature has been enabled on port 2/1. PAgP has removed port 2/1 from the EtherChannel bundle. The STP PortFast BPDU Guard feature has disabled port 2/1 on the switch
What are three important s teps in troubleshooting STP problems? (Choose three.) Administratively create bridge loops and see what path the traffic takes. Administratively disable multicasting and check to s ee if connectivity is restored. Check each side of a point-to-point link for duplex mismatch. Adjust BPDU timers so that there is less overhead traffic on the switching fabric. Administratively disable ports that should be blocking and check to see if connectivity is restored. Capture traffic on a saturated link and c heck whether identical frames are traversing multiple links
Which statement is true about UDLD? It is automatically enabled.
It allows devices to transmit traffic one way. It will disable an EtherChannel bundle if one link has failed. It allows a switch to detect a unidirectional link and shut down the affected interface
Which two statements are true about STP root guard? (Choose two.) Root guard is enabled on a per-port basis. Root guard requires that PortFast be enabled on a switch port. Root guard re-enables a switch port once it stops receiving superior BPDUs. Root guard should be configured on all ports on the desired root bridge to prevent another bridge from becoming the root. If a root guard enabled port receives a inferior BPDU from a nonroot switch, the port transitions to the blocking state to prevent a root bridge election
What happens when a switch running IEEE 802.1D receives a topology change message from the root bridge? The switch uses the forward delay timer to age out entries in the MAC address table. The switch uses the max-age timer to age out entries in the MAC address table. The switch uses the hello to age out entries in the MAC address table. The switch uses the forward delay and the max-age timer to age out entries in the MAC address table
Which STP timer defines the length of time spent in the listening and learning states? hello time forward aging forward delay max age max delay
Which three statements about RSTP are true? (Choose three.) An RSTP BPDU carries information about port roles and is sent to neighbor s witches only. RSTP elects a root bridge in exactly the same way as 802.1D. RSTP is capable of reverting back to 802.1D but still maintains the benefits of 802.1w. RSTP is rec ognized as t he IEEE 802.1w standard. There are only three RSTP port states: discarding, listening, and forwarding. UplinkFast and BackboneFast are compatible with RSTP
Which protocol extends the IEEE 802.1w Rapid Spanning Tree (RST) algorithm to multiple spanning trees? STP RSTP+ CST MST
Which protocol should an administrator recommend to manage bridged links when the customer requires a fully redundant network that can utilize load balancing technologies and reconverge on link failures in less than a second?
IEEE 802.1Q (CST) IEEE 802.1s (MST) Cisco PVST+ IEEE 802.1D(STP)

What is an advantage to using a trunk link to connect a s witch to an external router that is providing inter-VLAN routing? works with any s witch that supports VLANs and trunking lowers latency provides redundancy to the VLANs reduces CPU overhead
Refer to the exhibit and the partial configuration taken on router RTA. Users on VLAN 5 cannot communicate with the users on VLAN 10. What should be done to fix the problem? A dynamic routing protocol should be configured on the router. Two static routes should be configured on the router, each pointing to each subnet. The Fa0/0 interface should be configured with a primary IP address of 10.10.5.1/24 and a secondary IP address of 10.10.10.1/24. The subinterfaces of the router should be configured with 802.1Q encapsulation
Refer to the exhibit. The router has been properly configured for the trunking interface. Which statement is true about the routing table on the router? It will show a next hop address of the switch for both VLANs. It will show one trunking route to 10.0.0.0/8. It should contain routes to the 10.10.10.0/24 and the 10.10.11.0/24 networks. Because the switch is not configured properly to trunk VLAN 1 and VLAN 2, the routing table of the router will not show routes to either VLAN . Because the switch port fa0/1 is in access mode, the routing table of the router will not show any routes
Refer to the exhibit. Which statement is tr ue regarding the diagram and show ip route command output? Because no routing protocol has been configured, the router will not forward packets between workstations. The default gateway for hosts on VLAN 10 should be the Fa0/0 IP address of the router. The default gateway for hosts on VLAN 10 should be the Fa0/0.1 IP address of the router. The default gateway for hosts on VLAN 10 should be the Fa0/0.2 IP address of the router. Because their packets are being trunked, hosts on VLAN 10 do not need a default gateway
Which two statements are true about routed ports on a multilayer switch? (Choose two.) A routed port behaves like a regular router interface and supports VLAN subinterfaces. A routed port is a physical switch port with Layer 2 capability. A routed port is not associated with a particular VLAN. To create a routed port requires removal of Layer 2 port functionality with the no switchport interface configuration command. The interface vlan global configuration command is used to create a routed port
Which two statements are true about switched virtual interfaces (SVI) on a multilayer switch? (Choose two.) An SVI behaves like a regular router interface but does not support VLAN subinterfaces. An SVI is a physical switch port with Layer 3 capability. By default, an SVI is cr eated for the default VLAN (VLAN1). Only one SVI can be associated with a VLAN. To create an SVI requires removal of Layer 2 port f unctionality with t he no switchport interface configuration command
Which three statements about a r outed switch interface are true? (Choose three.) A routed switch port is a physical device that is associated with several VLANs. A routed switch port is created by configuring a Layer 2 port with the no switchport interface configuration command and assigning an IP address. A routed switch port is created by entering VLAN interface configuration mode and assigning an IP address. A routed switch port is a virtual Layer 3 interface that can be configured for any VLAN that exists on a Layer 3 switch. A routed switch port provides an interface that may provide a Layer 3 connection to a next-hop router.
A routed switch port can serve as a default gateway for devices
Refer to the exhibit and the partial configuration taken on routers RTA and RTB. A ll users can ping their gateways, but users on VLAN 5 and VLAN 10 cannot communicate with the users on VLAN 20. What should be done to solve the problem? A dynamic routing protocol or static routes should be configured on the routers. A trunk should be configured between routers RTA and RTB. RTA interface Fa0/1 and RTB Fa0/1 should be configured with three subinterfaces, each with ISL encapsulation. RTA interface Fa0/1 and RTB Fa0/1 should be configured with three subinterfaces, each with 802.1Q encapsulation
Which statement describes what occurs when a DHCP request is forwarded through a router that has been configured with the
ip helper-address command?

Refer to the exhibit. What additional configuration is required for host A to r eceive IP configuration from the DHCP server? The ip address dhcp command is r equired on interface Fa0/0. The ip dhcp information option command is required on interface Fa0/1. The ip helper-address 10.1.2.10 command is required on interface Fa0/0. The ip forward-protocol 37 global configuration command is required to forward DNS requests to IP address 10.1.2.10. The ip forward-protocol 67 global configuration command is required to forward DHCP requests to IP address 10.1.2.10. The ip forward-protocol 69 global configuration command is required to forward TFTP requests to IP address 10.1.2.10
Which three events will cause the Forwarding Information Base (FIB) table to be updated? (Choose three.) An ARP entry for the destination next hop changes, ages out, or is removed. The FIB table is cleared with the clear fib adjacency * command. The routing table entry for the next hop changes. The IP packets have an expiring TTL counter. The TCAM table is flushed and reactivated. The routing table entry for a prefix changes
Which condition will cause a packet to be process-switched instead of CEF switched? packets that are switched to an o utgoing interface with an outbound ACL applied packets with a destination interface that is c hosen by a routing protocol packets that need to be fragmented on the outgoing interface packets with a destination interface that is c hosen by a static route packets that use TCP header options
Which statement is true about the CEF f orwarding process? The FIB table contains the Layer 2 rewrite information. Adjacency table lookups use the closest Layer 3 prefix match. The adjacency table eliminates the need for the ARP protocol. After an IP prefix match is made, the process determines the associated Layer 2 header rewrite information from the adjacency table
What is true about TCAM lookups that ar e associated with CEF switching? TCAM includes only Layer 3 lookup information. A single TCAM lookup provides Layer 2, Layer 3, and ACL information TCAM lookup tables are used only for the Layer 3 forwarding operation. TCAM lookup tables are used only for the rapid processing of ACLs within CEF
Refer to the exhibit. An administrator wants to ensure that CEF is functioning properly on the switches between hosts A and B. If the administrator wants to verify the CEF FIB table entry for the route 10.10.5.0/24 on Sw_MLSA, what should the adjacency IP address be? 10.10.10.1 10.10.10.2 10.10.5.1 10.10.5.2
Refer to the exhibit and the show ip cef output. What can be concluded from the output? The output validates that the CEF FIB entry for 10.10.5.0/24 is correct. The cached adjacency address is 10.10.10.1. The next hop address is 10.10.10.1. The output shows that packets destined to 10.10.5.0/24 have not been processed by CEF
Refer to the exhibit. What action does the command standby 1 track Serial0/0/0 on router R1 perform? It links the default gateway virtual address 192.168.21.10 to the IP address 192.168.31.1 on interface Serial0/0/0. It links the default gateway virtual address 192.168.21.10 to the IP address 192.168.42.2 on interface Serial0/0/0. It tracks the state of the Fa0/0 interface on R1 and brings down the priority of s tandby group 1 if the i nterface goes down. It tracks the state of the Serial0/0/0 interface on R1 and brings down the priority of standby group 1 if the interface goes down
Refer to the exhibit. What statement is true about the output of the show standby command? The current priority of this router is 120. The router is currently forwarding packets. This router is tracking two properly operating interfaces. This router is i n the HSRP down state because its tracked interfaces are down
Refer to the exhibit. Switch DSw1 is the active virtual gateway (AVG) and DSw2 is an active v irtual forwarder (AVF). Based on this i nformation, which two GLBP statements are true? (Choose two.) GLBP is a Cisco proprietary protocol and is supported on all Cisco Catalyst and Cisco r outer platforms. None of the switches have had their priority configured. Switch DSw1 assigns the virtual IP addresses to switch DSw2. Switch DSw2 has been configured with the glbp 1 priority 95 command. Two more multilayer switches could join this group. When host A sends an ARP message for the gateway IP address, switch DSw1 returns the physical MAC address of switch DSw2
Refer to the exhibit. Based on the provided configuration, which routers are the master and the backup virtual routers for the hosts that are connected to the VRRP group 1? Router R1 is the master for all hosts, and router R2 is the backup for all hosts in the group. Router R1 is the master for Host1 and Host2. Router R2 is the master for Host3 and Host4. Router R1 is the master for Host3 and Host4. Router R2 is the backup for Host3 and Host4. Because of incorrect configuration of the default gateway on the hosts, none of the routers is the master for the VRRP group
How does Cisco IOS server load balancing (SLB) enhance security of a real server? The IP address of the real server is not needed with IOS SLB, which relies only on MAC addresses. The IP address of the real server is translated with Network Address Translation (NAT). The IP address of the real server is advertised as part of a distinct network. The IP address of the real server is never announced to the external network
How is server IP addressing handled by Cisco IOS s erver load balancing (SLB) in dispatched mode? The default gateway address for the subnet is assigned to the virtual server.

After the first multicast packet is received by the Receivers and the switchover takes place, how will the multicast traffic continue to flow from the Source to the Receivers? The traffic will flow via source tree f rom the Source to the Receivers. The traffic will flow via shared tree from the Source to the RP and via shared tree from the RP to the Receivers. The traffic will flow via shared tree fr om the Source to the RP and via source tree from the RP to the Receivers. The traffic will flow via source tree f rom the Source to the RP and via shared tree from the RP to t he Receivers
Which two statements about Protocol Independent Multicast (PIM) are true? (Choose two.) PIM does not require an IGP protocol to be configured in the network. PIM should be configured only on the first and the last hop routers in the multicast tree. PIM should be configured on the device that hosts the source of the muticast traffic. PIM Sparse Mode is most useful when there are few senders, many receivers, and the vo lume of multicast traffic is high. PIM is a multicast routing protocol that makes packet-forwarding decisions independent of the unicast IP routing protocol that is running in the network. Three of the forwarding modes for PIM are PIM Dense Mode (PIM-DM), PIM Sparse Mode (PIM-SM), and PIM Sparse-Dense Mode
Which MAC multicast address correctly maps to the IP multicast address 224.10.50.4? 01.00.5E.10.32.04 01.00.5E.10.50.04 01.00.5E.0A.32.04 01.00.5E.0A.50.04

All IP multicast group addresses fall in the range from 224.0.0.0 through 254.255.255.255. GLOP addresses and limited scope addresses are two types of IP multicast addresses. IP addresses between 233.0.0.0 and 233.255.255.255 are reserved link-local addresses. IP addresses between 224.0.0.1 and 239.255.255.255 can be as signed to the s ources of multicast traffic. IP address 224.0.1.1 is a globally scoped address that has been reserved for the Network Time Protocol ( NTP).
Which three statements are true a bout Protocol Independent Multicast (PIM) implementation on Cis co routers? ( Choose three.) Bidir-PIM is suited for multicast with larger numbers of sources. In PIM-SM deployment, all routers create only (*,G) entries for the multicast groups. In PIM-DM, a multicast sender first registers with the RP, and the data stream begins to flow from sender to RP to receiver. Available network bandwidth is overutilized outside of the multicast routing zone because multiple streams of data are required between distant routers in place of a single transmission. All routers in the PIM network learn about the active group-to-RP mapping from the RP mapping agent by automatically joining the Cisco-RP-discovery (224.0.1.40) multicast group. In a PIM-SM network, the routers have the SPT threshold set to 0 by default which guarantees that the last-hop router switches to SPT mode as soon as the host starts receiving the multicast
