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

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

The MAC address-table will hold addresses 180 seconds longer than the default of 10 minutes. ARP requests will be processed less frequently by the switch. E. Answer: A Explanation: You can configure the amount of time that an entry (the packet source MAC address and port that packet ingresses) remain in the MAC table. Entering the value 0 disables the MAC aging. such as broadcast. VTP pruning increases available bandwidth by restricting flooded traffic to those trunk links that the traffic must use to access the appropriate network devices. command aliases E. If a VLAN is not specified.com .

You can configure ports or EtherChannels in any VLAN as SPAN sources. B. This is where errdisable autorecovery can be of great assistance. D. The SDM VLAN template causes the MAC address-table to overflow. What is the root cause of this issue? A. UDLD failure.There are a number of events which can disable a link on a Catalyst switch. B. C. Choosing the VLAN template will actually disable routing (number of entry for unicast or multicast route is zero) in hardware. The port channel can be used as a SPAN source. VLAN filters are required to ensure traffic mirrors effectively. but not a destination. manual intervention by an administrator is necessary to restore the interface to working order. The SDM template is causing the CPU of the switch to spike during peak working hours. The switch needs to be rebooted before the SDM template takes effect. http://www. The switch reload is required to use a new SDM template. all processing overflow is sent to the CPU which can have a major impact on the performance of the switch. and (ideally) correct the issue. The ACL merge algorithm. A port-channel interface (an EtherChannel) can be a SPAN source. SPAN can monitor one or more source ports or EtherChannels in a single SPAN session. Answer: C Explanation: SDM Template Notes: All templates are predefined. such as the detection of a loopback. By default. The VLAN receives additional frames from neighboring switches. QUESTION 14 A network engineer deployed a switch that operates the LAN base feature set and decides to use the SDM VLAN template.

The IP source binding table has bindings that are learned by DHCP snooping or are manually configured (static IP source bindings). The DHCP server does not support information option 82. The MAC address of the DHCP client is learned as a secure address only when the switch receives non-DHCP data traffic. C. but is unable to configure ip verify source under several of the interfaces. except for DHCP packets allowed by DHCP snooping. including access and trunk ports. The configured SVIs on the switch have been removed for the associated interfaces. there are two caveats: The DHCP server must support option 82. The switch is configured for sdm prefer routing as the switched database management template. DHCP snooping must be enabled on all VLANs. A port access control list (ACL) is applied to the interface. 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. The local DHCP server is disabled prior to enabling IP Source Guard. You can enable IP source guard when DHCP snooping is enabled on an untrusted interface.

optimize support for certain features.

QUESTION 36
Which SDM template disables routing and supports the maximum number of unicast MAC
addresses?

A. VLAN
B. access
C. default
D. routing

Answer: A
Explanation:
To allocate ternary content addressable memory (TCAM) resources for different usages, the
switch SDM templates prioritize system resources to optimize support for certain features. You
can select SDM templates to optimize these features:
Access--The access template maximizes system resources for access control lists (ACLs) to
accommodate a large number of ACLs.
Default--The default template gives balance to all functions.
Routing--The routing template maximizes system resources for IPv4 unicast routing, typically
required for a router or aggregator in the center of a network.
VLANs--The VLAN template disables routing and supports the maximum number of unicast MAC
addresses. It would typically be selected for a Layer 2 switch.

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.

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).
