Exam A

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.

Correct Answer: E
Section: (none)
Explanation

Explanation/Reference:
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 3

RatedR Converted VCE

A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the

diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery Protocol, but it
has several routing neighbor relationships. What would cause the output to show only the single neighbor?

A. The routers are connected via a Layer 2 switch.
B. IP routing is disabled on neighboring devices.
C. Cisco Express Forwarding is enabled locally.
D. Cisco Discovery Protocol advertisements are inconsistent between the local and remote devices.

Correct Answer: A
Section: (none)
Explanation

Explanation/Reference:
Explanation:
If all of the routers are connected to each other using a layer 2 switch, then each router will only have the single
switch port that it connects to as its neighbor. Even though multiple routing neighbors can be formed over a
layer 2 network, only the physical port that it connects to will be seen as a CDP neighbor. CDP can be used to
determine the physical topology, but not necessarily the logical topology.

QUESTION 4
After the implementation of several different types of switches from different vendors, a network engineer
notices that directly connected devices that use Cisco Discovery Protocol are not visible. Which vendor-neutral
protocol could be used to resolve this issue?

A. Local Area Mobility
B. Link Layer Discovery Protocol
C. NetFlow
D. Directed Response Protocol

Correct Answer: B
Section: (none)
Explanation

Explanation/Reference:
Explanation:
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol in the Internet Protocol Suite
used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area
network, principally wired Ethernet. LLDP performs functions similar to several proprietary protocols, such as
the Cisco Discovery Protocol (CDP). http://en.wikipedia.org/wiki/ Link_Layer_Discovery_Protocol

QUESTION 5
Several new switches have been added to the existing network as VTP clients. All of the new switches have
been configured with the same VTP domain, password, and version. However, VLANs are not passing from the
VTP server (existing network) to the VTP clients. What must be done to fix this?

A. Remove the VTP domain name from all switches with "null" and then replace it with the new domain name.
B. Configure a different native VLAN on all new switches that are configured as VTP clients.
C. Provision one of the new switches to be the VTP server and duplicate information from the existing network.
D. Ensure that all switch interconnects are configured as trunks to allow VTP information to be transferred.

Explanation/Reference: Explanation: VTP allows switches to advertise VLAN information between other members of the same VTP domain. the VLANs in the range 1006 to 4094 are removed from VTP control. Switch A. and C are trunked together and have been properly configured for VTP. If any password is set. VTP allows a consistent view of the switched network across all switches. Make sure that if EtherChannels are created between two switches. Switch B is configured in transparent mode. There are several reasons why the VLAN information can fail to be exchanged. Make sure that all ports that interconnect switches are configured as trunks and are actually trunking. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use. B. make sure that the password is the same on both sides. VTP does not support extended VLANs and should be manually added to all switches.range VLANs (VLAN numbers 1006 to 4094). CISCO and cisco are two different domain names. VTP version 3 supports extended-range VLANs (VLAN numbers 1006 to 4094). VTP authentication is required when using extended VLANs because of their ability to cause network instability. RatedR Converted VCE . Correct Answer: B Section: (none) Explanation Explanation/Reference: Explanation: VTP version 1 and VTP version 2 do not propagate configuration information for extended. Switch C receives VLAN information from the VTP server Switch A. QUESTION 7 Refer to the exhibit. What should be configured for extended VLANs? A.cisco. but Switch B does not receive any VLAN information. the extended VLANs are not being propagated to other VTP switches. Make sure that no password is set between the server and client. The VTP domain name must match and it is case sensitive. If you convert from VTP version 3 to VTP version 2. B. Verify these items if switches that run VTP fail to exchange VLAN information: VTP information only passes through a trunk port. only Layer 2 EtherChannels propagate VLAN information. D. Enable VTP version 3. Make sure that the VLANs are active in all the devices. What is the most probable cause of this behavior? A. You must configure extended-range VLANs manually on each network device. Ensure that all switches run the same Cisco IOS version. All VLAN changes must be done on this switch in order to have them propagated to the VTP clients.shtml QUESTION 6 After implementing VTP. One of the switches must be the VTP server in a VTP domain. which supports extended VLAN propagation. http://www.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080890613. C.

QUESTION 9 After the recent upgrade of the switching infrastructure. C. The VTP revision number of Switch B is higher than that of Switch A. while Switch C is configured with a trunk port to Switch B.1D STP. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements. B. is that VTP pruning has been configured. B. but transparent switches do forward VTP advertisements that they receive out their trunk ports in VTP Version 2. What would cause this issue? A. QUESTION 8 Refer to the exhibit.B. B. VTP pruning is configured globally on all switches and it removed VLANs from the trunk interface that is connected to Switch C. and unknown unicast traffic across all trunk links within a VTP domain even though receiving switches might discard them. Switch B is configured with an access port to Switch A. a switch floods broadcast. C. RatedR Converted VCE . Switch B has all VLANs. Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: VTP transparent switches do not participate in VTP. A VTP authentication mismatch occurred between Switch A and Switch B. Switch A.1D STP and PortFast have been configured by default on all newly implemented Cisco Catalyst switches. 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. The best explanation for why switch C is not seeing traffic from only some of the VLANs. The VTP revision number of the Switch B is higher than that of Switch A." What is the reason for this change? A. VTP pruning blocks unneeded flooded traffic to VLANs on trunk ports that are included in the pruning-eligible list. and C are trunked together and have been properly configured for VTP. D. multicast. The new switches are using RSTP instead of legacy IEEE 802. D. IEEE 802. but Switch C is not receiving traffic from certain VLANs. Correct Answer: C Section: (none) Explanation Explanation/Reference: 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. VTP pruning is disabled by default. The trunk between Switch A and Switch B is misconfigured. Without VTP pruning.

Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: RSTP can only achieve rapid transition to the forwarding state on edge ports and on point-to. a network administrator can manually disable a port. Backup port A backup/redundant path to a segment where another bridge port already connects. This makes them candidates for rapid transition to the forwarding state. These ports are allowed to immediately enter the forwarding state rather than passively wait for the network to converge. In switched networks today. What is the reason for this? A.point links. STP is unable to achieve rapid transition for trunk links. access lists B. it has been determined that several ports are not transitioning as they should. the switch must be attached to a hub. This automatic link type setting can be overridden by explicit configuration. This path is different than using the root port. The port roles have been adjusted based on the interface bandwidth and timers of the new Cisco Catalyst switches. Disabled port Not strictly part of STP. D.C. 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. not on trunk links. C. DTP in nonegotiate C. PBR Correct Answer: C Section: (none) Explanation Explanation/Reference: RatedR Converted VCE . The alternative port moves to the forwarding state if there is a failure on the designated port for the segment. To have two links to the same collision domain. The link type is automatically derived from the duplex mode of a port. Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: RSTP works by adding an alternative port and a backup port compared to STP. RSTP has been enabled per interface and not globally. The switch does not have the processing power to ensure rapid transition for all ports. QUESTION 10 An administrator recently configured all ports for rapid transition using PortFast. B. A port that operates in full- duplex is assumed to be point-to-point. VTP pruning D. After testing. The administrator has defined the switch as the root in the STP domain. The backup port applies only when a single switch has two links to the same segment (collision domain). QUESTION 11 Which technique automatically limits VLAN traffic to only the switches that require it? A. most links operate in full-duplex mode and are treated as point-to-point links by RSTP. The STP root bridge selection is forcing key ports to remain in non-rapid transitioning mode. while a half-duplex port is considered as a shared port by default. D.

The MAC address-table will hold addresses 180 seconds longer than the default of 10 minutes. command aliases 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. Entering the value 0 disables the MAC aging. E. This example shows how to set the aging time for entries in the MAC address table to 600 seconds (10 minutes): switch# configure terminal switch(config)# mac-address-table aging-time 600 QUESTION 13 While working in the core network building. such as broadcast.

The SDM VLAN template causes the MAC address-table to overflow. the network administrator notices that not all traffic is being replicated to the management server. SPAN can monitor one or more source ports or EtherChannels in a single SPAN session. such as the detection of a loopback. There is no way to edit template category individual values. VLAN filters are required to ensure traffic mirrors effectively. manual intervention by an administrator is necessary to restore the interface to working order. D. RSPAN must be used to capture EtherChannel bidirectional traffic. but not a destination. some configurations may be prone to accidental violations. this can be done by issuing shutdown followed by no shutdown on the interface. If the boundary is exceeded. A port- channel interface (an EtherChannel) can be a SPAN source. Trunk ports or EtherChannels can be configured as sources and mixed with nontrunk sources. Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: A source port or EtherChannel is a port or EtherChannel monitored for traffic analysis. The switch needs to be rebooted before the SDM template takes effect. The VLAN template disables routing in hardware. The switch reload is required to use a new SDM template. The first eight lines (up to Security ACEs) represent approximate hardware boundaries set when a template is used. The SDM template is causing the CPU of the switch to spike during peak working hours. The port channel can be used as a SPAN source. and a steady recurrence of these can amount to a huge time sink for the administrative staff. as opposed to the original access control entries (ACEs) configured by the user. By default. assess. C. all processing overflow is sent to the CPU which can have a major impact on the performance of the switch. Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: SDM Template Notes: All templates are predefined. UDLD failure.There are a number of events which can disable a link on a Catalyst switch. We can configure the switch to automatically re-enable any error- disabled interfaces after a specified timeout period.

QUESTION 15 An access switch has been configured with an EtherChannel port. You can configure both Layer 2 and Layer 3 ports and EtherChannels as SPAN sources. D. What is a cause for this issue? A. This gives the offending issue a chance to be cleared by the user (for example. SPAN encapsulation replication must be enabled to capture EtherChannel destination traffic. You can configure ports or EtherChannels in any VLAN as SPAN sources. B. generate the number of TCAM entries listed for security and QoS ACEs. but not a destination. The idea behind requiring administrative action is so that a human engineer can intercede. What is the root cause of this issue? A. or a broadcast storm. Choosing the VLAN template will actually disable routing (number of entry for unicast or multicast route is zero) in hardware. However. B.

UDLD Correct Answer: D Section: (none) Explanation Explanation/Reference: Explanation: If a switch loses connectivity. UplinkFast provides fast convergence after a direct link failure and achieves load balancing between redundant Layer 2 links using uplink groups. This enables UDLD in normal mode. UplinkFast E. When UDLD is finally enabled on the other end. Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: By default. UDLD moved into aggressive mode after inconsistent acknowledgements were detected. only one of which is forwarding at any given time. it begins using the alternate paths as soon as the spanning tree selects a new root port. Specifically. The bidirectional status of "unknown" indicates that the port will go into the disabled state because it stopped receiving UDLD packets from its neighbor. By enabling UplinkFast with the spanning-tree uplinkfast global configuration command. The root port transitions to the forwarding state immediately without going through the listening and learning states. The port will remain operational during this time. PortFast C. or individually on specific interfaces with the command udld port. so when UDLD is first enabled and does not detect a neighbor the link state is considered unknown.

Explanation/Reference:
Explanation:
A LACP port priority is configured on each port using LACP. The port priority can be configured automatically or
through the CLI. LACP uses the port priority with the port number to form the port identifier. The port priority
determines which ports should be put in standby mode when there is a hardware limitation that prevents all
compatible ports from aggregating. The higher the number, the lower the priority. The valid range is from 1 to
65535. The default is 32768.

QUESTION 64 A network engineer changed the port speed and duplex setting of an existing EtherChannel bundle that uses the PAgP protocol. PAgP requires that all ports in the channel belong to the same VLAN or are configured as trunk ports. A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel. The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 16 Gbps only for Gigabit EtherChannel. PAgP does not group ports that operate at different speeds or port duplex.

The root guard ensures that the port on which root guard is enabled is the designated port. Normally, root
bridge ports are all designated ports, unless two or more ports of the root bridge are connected together. If the
bridge receives superior STP Bridge Protocol Data Units (BPDUs) on a root guard-enabled port, root guard
moves this port to a root-inconsistent STP state. This

root-inconsistent state is effectively equal to a listening state. No traffic is forwarded across this port. In this
way, the root guard enforces the position of the root bridge.

Explanation/Reference:
Explanation:
The VSS is made up of the following:

Virtual switch members: Cisco Catalyst 6500 Series Switches (up to two switches with initial release) deployed
with the Virtual Switching Supervisor 720 10GE Virtual switch link (VSL): 10 Gigabit Ethernet connections (up to
eight using EtherChannel) between the virtual switch members.

QUESTION 78
Which statement describes what happens if all VSL connections between the virtual switch members are lost?

A. Both virtual switch members cease to forward traffic.
B. The VSS transitions to the dual active recovery mode, and both virtual switch members continue to forward
traffic independently.
C. The virtual switch members reload.
D. The VSS transitions to the dual active recovery mode, and only the new active virtual switch continues to

Correct Answer: D
Section: (none)
Explanation

Explanation/Reference:
Explanation:
What happens if all VSL connections between the virtual switch members are lost? VSLs can be configured
with up to eight links between the two switches across any combination of line cards or supervisor ports to
provide a high level of redundancy. If for some rare reason all VSL connections are lost between the virtual
switch members leaving both the virtual switch members up, the VSS will transition to the dual active recovery
mode. The dual active state is detected rapidly (subsecond) by any of the following three methods:
Enhancement to PAgP used in MEC with connecting Cisco switches L3 Bidirectional Forwarding Detection
(BFD) configuration on a directly connected link (besides VSL) between virtual switch members or through an
L2 link through an access layer switch L2 Fast-Hello Dual-Active Detection configuration on a directly
connected link (besides VSL) between virtual switch members (supported with 12.2(33)SXI) In the dual active
recovery mode, all interfaces except the VSL interfaces are in an operationally shut down state in the formerly
active virtual switch member. The new active virtual switch continues to forward traffic on all links.

Method lists for authorization define the ways that authorization will be performed and the sequence in which
these methods will be performed. A method list is simply a named list describing the authorization methods to
be queried (such as RADIUS or TACACS+), in sequence. Method lists enable you to designate one or more
security protocols to be used for authorization, thus ensuring a backup system in case the initial method fails.
Cisco IOS software uses the first method listed to authorize users for specific network services; if that method
fails to respond, the Cisco IOS software selects the next method listed in the method list. This process
