QUESTION 1
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?

A. Enable Cisco Express Forwarding to allow for more effective traffic sharing over the
EtherChannel bundle.
B. Adjust the EtherChannel load-balancing method based on destination IP addresses.
C. Disable spanning tree on all interfaces that are participating in the EtherChannel bundle.
D. Use link-state tracking to allow for improved load balancing of traffic upon link failure to the
server.
E. Adjust the EtherChannel load-balancing method based on source IP addresses.

Answer: E
Explanation:
EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers,
and either source mode, destination mode, or both. The mode you select applies to all
EtherChannels that you configure on the switch. Use the option that provides the greatest variety
in your configuration.
For example, if the traffic on a channel only goes to a single MAC address (which is the case in
this example, since all traffic is going to the same web server), use of the destination MAC
address results in the choice of the same link in the channel each time. Use of source addresses
or IP addresses can result in a better load balance.

QUESTION 2
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?

A. All VLAN traffic is sent to the SPAN destination interface.
B. Traffic from VLAN 4 is not sent to the SPAN destination interface.
C. Filtering a trunked SPAN port effectively disables SPAN operations for all VLANs.
D. The trunk's native VLAN must be changed to something other than VLAN 1.
E. Traffic from VLANs 1 to 8, 39, and 52 is replicated to the SPAN destination port.

Answer: E
Explanation:
The "monitor session filter" command is used to specify which VLANS are to be port mirrored
using SPAN.
This example shows how to monitor VLANs 1 through 5 and VLAN 9 when the SPAN source is a
trunk interface:
Switch(config)# monitor session 2 filter vlan 1 - 5 , 9

One of the switches must be the VTP server in a VTP domain. Verify these items if switches that run VTP fail to exchange VLAN information: VTP information only passes through a trunk port. There are several reasons why the VLAN information can fail to be exchanged. the VLANs in the range 1006 to 4094 are removed from VTP control. VTP allows a consistent view of the switched network across all switches. only Layer 2 EtherChannels propagate VLAN information. D. and C are trunked together and have been properly configured for VTP.range VLANs (VLAN numbers 1006 to 4094). Make sure that no password is set between the server and client. which supports extended VLAN propagation. B. Make sure that all ports that interconnect switches are configured as trunks and are actually trunking. CISCO and cisco are two different domain names. QUESTION 7 Refer to the exhibit.cisco. If any password is set. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use. What is the most probable cause of this behavior? Get Complete Collection of 300-115 Exam's Question and Answers. The VTP domain name must match and it is case sensitive. All VLAN changes must be done on this switch in order to have them propagated to the VTP clients.VTP allows switches to advertise VLAN information between other members of the same VTP domain. VTP authentication is required when using extended VLANs because of their ability to cause network instability. Switch A. Answer: B Explanation: VTP version 1 and VTP version 2 do not propagate configuration information for extended. but Switch B does not receive any VLAN information. What should be configured for extended VLANs? A. You must configure extended-range VLANs manually on each network device. Switch C receives VLAN information from the VTP server Switch A. B. VTP does not support extended VLANs and should be manually added to all switches.exam. Make sure that if EtherChannels are created between two switches.shtml QUESTION 6 After implementing VTP. the extended VLANs are not being propagated to other VTP switches.

B. VTP pruning blocks unneeded flooded traffic to VLANs on trunk ports that are included in the pruning-eligible list." What is the reason for this change? A. D. B. A VTP authentication mismatch occurred between Switch A and Switch B. the network engineer notices that the port roles that were once "blocking" are now defined as "alternate" and "backup. The trunk between Switch A and Switch B is misconfigured. Answer: C Explanation: VTP pruning increases network available bandwidth by restricting flooded traffic to those trunk links that the traffic must use to reach the destination devices. The VTP revision number of the Switch B is higher than that of Switch A. The new switches are using RSTP instead of legacy IEEE 802. http://www. IEEE 802. D.exam. Switch B has all VLANs. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements. multicast.com . C. B. C. The best explanation for why switch C is not seeing traffic from only some of the VLANs. a switch floods broadcast. Switch B is configured in transparent mode.

A port that operates in full-duplex is assumed to be point-to-point. Backup port A backup/redundant path to a segment where another bridge port already connects. To have two links to the same collision domain. a network administrator can manually disable a port. The administrator has defined the switch as the root in the STP domain. Catalyst switches. These ports are allowed to immediately enter the forwarding state rather than passively wait for the network to converge. The port roles have been adjusted based on the interface bandwidth and timers of the new Cisco Catalyst switches. DTP in nonegotiate C. PBR Answer: C Get Complete Collection of 300-115 Exam's Question and Answers. not on trunk links. QUESTION 11 Which technique automatically limits VLAN traffic to only the switches that require it? A. QUESTION 10 An administrator recently configured all ports for rapid transition using PortFast. Disabled port Not strictly part of STP. VTP pruning D. most links operate in full-duplex mode and are treated as point-to-point links by RSTP. After testing. access lists B. The link type is automatically derived from the duplex mode of a port. The backup port applies only when a single switch has two links to the same segment (collision domain). C. D. The alternative port moves to the forwarding state if there is a failure on the designated port for the segment. D.exam. This automatic link type setting can be overridden by explicit configuration. the switch must be attached to a hub. while a half-duplex port is considered as a shared port by default. RSTP has been enabled per interface and not globally. Answer: C Explanation: RSTP can only achieve rapid transition to the forwarding state on edge ports and on point-to- point links. Answer: A Explanation: RSTP works by adding an alternative port and a backup port compared to STP. This makes them candidates for rapid transition to the forwarding state. STP is unable to achieve rapid transition for trunk links. C. http://www.com . RSTP bridge port roles: Root port A forwarding port that is the closest to the root bridge in terms of path cost Designated port A forwarding port for every LAN segment Alternate port A best alternate path to the root bridge. B. In switched networks today. it has been determined that several ports are not transitioning as they should. What is the reason for this? A. The STP root bridge selection is forcing key ports to remain in non-rapid transitioning mode. This path is different than using the root port. The switch does not have the processing power to ensure rapid transition for all ports.

ARP requests will be processed less frequently by the switch. multicast.Explanation: VTP pruning enhances network bandwidth use by reducing unnecessary flooded traffic. C. the link was placed into a non-forwarding state due to a fault with UDLD. The MAC address-table will be flushed every 3 minutes. E. VTP pruning increases available bandwidth by restricting flooded traffic to those trunk links that the traffic must use to access the appropriate network devices. To configure the aging time for all MAC addresses. D. a technician accidently bumps the fiber connection between two core switches and damages one of the pairs of fiber. http://www.

QUESTION 15 An access switch has been configured with an EtherChannel port. generate the number of TCAM entries listed for security and QoS ACEs. The switch needs to be rebooted before the SDM template takes effect. What is a cause for this issue? A. Answer: C Explanation: A source port or EtherChannel is a port or EtherChannel monitored for traffic analysis. B.There are a number of events which can disable a link on a Catalyst switch. and a steady recurrence of these can amount to a huge time sink for the administrative staff. You can configure ports or EtherChannels in any VLAN as SPAN sources. The ACL merge algorithm. The VLAN receives additional frames from neighboring switches. Choosing the VLAN template will actually disable routing (number of entry for unicast or multicast route is zero) in hardware. some configurations may be prone to accidental violations. The idea behind requiring administrative action is so that a human engineer can intercede. SPAN can monitor one or more source ports or EtherChannels in a single SPAN session.com . C. QUESTION 14 A network engineer deployed a switch that operates the LAN base feature set and decides to use the SDM VLAN template. B. assess. The first eight lines (up to Security ACEs) represent approximate hardware boundaries set when a template is used. http://www. D. A port-channel interface (an EtherChannel) can be a SPAN source. After configuring SPAN to monitor this port. and (ideally) correct the issue. SPAN encapsulation replication must be enabled to capture EtherChannel destination traffic. as opposed to the original access control entries (ACEs) configured by the user. This gives the offending issue a chance to be cleared by the user (for example. You can configure both Layer 2 and Layer 3 ports and EtherChannels as SPAN sources. The SDM template is causing the CPU of the switch to spike during peak working hours. manual intervention by an administrator is necessary to restore the interface to working order. the network administrator notices that not all traffic is being replicated to the management server. The port channel can be used as a SPAN source. The SDM VLAN template causes the MAC address-table to overflow. C. such as the detection of a loopback. Answer: C Explanation: SDM Template Notes: All templates are predefined. We can configure the switch to automatically re-enable any error-disabled interfaces after a specified timeout period.exam. However. The VLAN template disables routing in hardware. or a broadcast storm. D. Get Complete Collection of 300-115 Exam's Question and Answers. RSPAN must be used to capture EtherChannel bidirectional traffic. UDLD failure. The switch reload is required to use a new SDM template. but not a destination. this can be done by issuing shutdown followed by no shutdown on the interface. but not a destination. Trunk ports or EtherChannels can be configured as sources and mixed with nontrunk sources. There is no way to edit template category individual values. This is where errdisable autorecovery can be of great assistance. VLAN filters are required to ensure traffic mirrors effectively. all processing overflow is sent to the CPU which can have a major impact on the performance of the switch. by removing an unapproved device) without the need for administrative intervention. If the boundary is exceeded. What is the root cause of this issue? A. By default.

Layer 2 interfaces by filtering traffic based on the DHCP snooping binding database and on manually configured IP source bindings. using the ip verify source port- security interface configuration command.

The interfaces are configured as Layer 3 using the no switchport command. The IP source binding table has bindings that are learned by DHCP snooping or are manually configured (static IP source bindings). The local DHCP server is disabled prior to enabling IP Source Guard. except for DHCP packets allowed by DHCP snooping. After IP source guard is enabled on an interface. The configured SVIs on the switch have been removed for the associated interfaces. IP source guard is supported only on Layer 2 ports. The DHCP server does not support information option 82. its associated MAC address.exam. The MAC address of the DHCP client is learned as a secure address only when the switch receives non-DHCP data traffic. B. The port ACL allows only IP traffic with a source IP address in the IP source binding table and denies all other traffic. but is unable to configure ip verify source under several of the interfaces. or the client is not assigned an IP address. B. C. C. clients are not receiving an IP address via the DHCP server. Which option is the cause of this issue? A. No VLANs exist on the switch and/or the switch is configured in VTP transparent mode. The switch is configured for sdm prefer routing as the switched database management template. You can enable IP source guard when DHCP snooping is enabled on an untrusted interface.QUESTION 16 A DHCP configured router is connected directly to a switch that has been provisioned with DHCP snooping. Reference: http://www. You can configure IP source guard with source IP address filtering or with Get Complete Collection of 300-115 Exam's Question and Answers. 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. A network engineer is configuring the switch for DHCP snooping and IP Source Guard.com . including access and trunk ports. The MAC address in the DHCP packet is not learned as a secure address. even if they are not utilized for dynamic address allocation. the switch blocks all IP traffic received on the interface. there are two caveats: The DHCP server must support option 82. You can use IP source guard to prevent traffic attacks caused when a host tries to use the IP address of its neighbor. Answer: B Explanation: IP source guard is a security feature that restricts IP traffic on nonrouted. An entry in this table has an IP address. However. Static DHCP bindings are not configured on the switch.html#wp1069615 QUESTION 17 A switch is added into the production network to increase port capacity. The switch uses the IP source binding table only when IP source guard is enabled. A port access control list (ACL) is applied to the interface. D. Which option is the cause of the problem? A. http://www. DHCP snooping must be enabled on all VLANs.

Inter-switch Connectivity Configuration Requirements

- For operational and security reasons trunking should be unconditional
and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk
link.
- The two trunks between SwitchA and SwitchB need to be configured in a
mode that allows for the maximum use of their bandwidth for all vlans.
This mode should be done with a non-proprietary protocol, with SwitchA
controlling activation.
- Propagation of unnecessary broadcasts should be limited using manual
pruning on this trunk link.

During routine maintenance, it became necessary to shut down the GigabitEthernet1/0/1 interface
on DSW1 and DSW2. All other interfaces were up. During this time, DSW1 became the active
router for the VLAN 104HSRP group. As related to the VLAN 104HSRP group, what can to be
done to make the group function properly?

A. On DSW1, disable preempt.
B. On DSW2, decrease the priority value to a value less than 150.
C. On DSW1, increase the decrement value in the track command to a value greater than 6.
D. On DSW1, decrease the decrement value in the track command to a value less than 1.

Answer: C
Explanation:

We should NOT disable preempt on DS1. By do that, you will make Vlan104's HSRP group fail
function.
Example: if we are disable preempt on DS1. It can not become active device when G1/0/1 on
DS2 fail. In this question, G0/1/0 on DS1 & DS2 is shutdown. Vlan104 (left) : 150 -1 = 149.
Vlan104 (right) : 200 -155 = 145. Result is priority 149 > 145 ( Vlan104 on DS1 is active). If
increase the decrement in the track value to a value greater than 6 ( > or = 6). Vlan104 (left) : 150
-6 = 144. Result is priority 144 < 145 ( vlan104 on DS2 is active).
