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

VTP pruning blocks unneeded flooded traffic to VLANs on trunk ports that are included in the pruning-eligible list.com . A VTP authentication mismatch occurred between Switch A and Switch B. 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.

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

SPAN can monitor one or more source ports or EtherChannels in a single SPAN session.exam. This gives the offending issue a chance to be cleared by the user (for example. The SDM template is causing the CPU of the switch to spike during peak working hours. This is where errdisable autorecovery can be of great assistance. SPAN encapsulation replication must be enabled to capture EtherChannel destination traffic. VLAN filters are required to ensure traffic mirrors effectively. such as the detection of a loopback. the network administrator notices that not all traffic is being replicated to the management server. Answer: C Explanation: A source port or EtherChannel is a port or EtherChannel monitored for traffic analysis. You can configure ports or EtherChannels in any VLAN as SPAN sources. manual intervention by an administrator is necessary to restore the interface to working order. this can be done by issuing shutdown followed by no shutdown on the interface. However. by removing an unapproved device) without the need for administrative intervention. We can configure the switch to automatically re-enable any error-disabled interfaces after a specified timeout period. What is the root cause of this issue? A. Answer: C Explanation: SDM Template Notes: All templates are predefined. or a broadcast storm. and a steady recurrence of these can amount to a huge time sink for the administrative staff. and (ideally) correct the issue. The switch reload is required to use a new SDM template. The port channel can be used as a SPAN source. If the boundary is exceeded. The ACL merge algorithm. The switch needs to be rebooted before the SDM template takes effect. all processing overflow is sent to the CPU which can have a major impact on the performance of the switch. but not a destination. C. some configurations may be prone to accidental violations. The SDM VLAN template causes the MAC address-table to overflow. D.

The uplink group provides an alternate path in case the currently forwarding link fails. C. It would be prohibitively difficult to coordinate the configuration of UDLD on both ends of a link at the same time. the status will transition to bidirectional. When UDLD is finally enabled on the other end. STP immediately replaces the root port with an alternative root port. Answer: A Explanation: By default. The UDLD port is placed in the "unknown" state for 5 seconds until the next UDLD packet is received on the interface. so when UDLD is first enabled and does not detect a neighbor the link state is considered unknown. The root port transitions to the forwarding state immediately without going through the listening and learning states. The port is fully operational and no known issues are detected. UDLD Answer: D Explanation: If a switch loses connectivity. UDLD moved into aggressive mode after inconsistent acknowledgements were detected. The port will remain operational during this time. an uplink group consists of the root port (which is forwarding) and a set of blocked ports. only one of which is forwarding at any given time. an engineer notices that the current bidirectional state for an access port is "Unknown.com . it begins using the alternate paths as soon as the spanning tree selects a new root port. you can accelerate the choice of a new root port when a link or switch fails or when the spanning tree reconfigures itself.

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.

192.168.1.11/24

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.

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).
