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.

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

The trunk between Switch A and Switch B is misconfigured. B. VTP pruning is disabled by default. multicast. C. QUESTION 9 After the recent upgrade of the switching infrastructure. and C are trunked together and have been properly configured for VTP. B. is that VTP pruning has been configured. C. Switch B has all VLANs. RatedR Converted VCE . The VTP revision number of Switch B is higher than that of Switch A." What is the reason for this change? A. A VTP authentication mismatch occurred between Switch A and Switch B. Without VTP pruning. The VTP revision number of the Switch B is higher than that of Switch A. IEEE 802. while Switch C is configured with a trunk port to Switch B. B. but Switch C is not receiving traffic from certain VLANs. Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: VTP transparent switches do not participate in VTP. 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 blocks unneeded flooded traffic to VLANs on trunk ports that are included in the pruning-eligible list. Switch A. and unknown unicast traffic across all trunk links within a VTP domain even though receiving switches might discard them. The trunk between Switch A and Switch B is misconfigured. the network engineer notices that the port roles that were once "blocking" are now defined as "alternate" and "backup. VTP pruning is configured globally on all switches and it removed VLANs from the trunk interface that is connected to Switch C. The new switches are using RSTP instead of legacy IEEE 802.1D STP and PortFast have been configured by default on all newly implemented Cisco Catalyst switches.1D STP. The best explanation for why switch C is not seeing traffic from only some of the VLANs.B. a switch floods broadcast. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements. QUESTION 8 Refer to the exhibit. D. D. Switch B is configured with an access port to Switch A.

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

What solution allows the network switch to automatically recover from such an issue? A. D. By default. VTP pruning is disabled. the aging specification applies to all VLANs. This is how long a dynamic MAC address will remain in the CAM table. Entering the value 0 disables the MAC aging.table? A. ARP requests will be processed less frequently by the switch.

After configuring SPAN to monitor this port.There are a number of events which can disable a link on a Catalyst switch. QUESTION 14 A network engineer deployed a switch that operates the LAN base feature set and decides to use the SDM VLAN template. SPAN can monitor one or more source ports or EtherChannels in a single SPAN session. The SDM template is causing the CPU of the switch to spike during peak working hours. Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: A source port or EtherChannel is a port or EtherChannel monitored for traffic analysis. manual intervention by an administrator is necessary to restore the interface to working order. The VLAN receives additional frames from neighboring switches. The port channel can be used as a SPAN source. C. By default. The switch needs to be rebooted before the SDM template takes effect. SPAN encapsulation replication must be enabled to capture EtherChannel destination traffic. B.

There is no way to edit template category individual values. such as the detection of a loopback. this can be done by issuing shutdown followed by no shutdown on the interface. What is the root cause of this issue? A. QUESTION 15 An access switch has been configured with an EtherChannel port. Trunk ports or EtherChannels can be configured as sources and mixed with nontrunk sources. The first eight lines (up to Security ACEs) represent approximate hardware boundaries set when a template is used. and (ideally) correct the issue. The switch reload is required to use a new SDM template. RSPAN must be used to capture EtherChannel bidirectional traffic. Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: SDM Template Notes: All templates are predefined. You can configure both Layer 2 and Layer 3 ports and EtherChannels as SPAN sources. D. all processing overflow is sent to the CPU which can have a major impact on the performance of the switch. We can configure the switch to automatically re-enable any error- disabled interfaces after a specified timeout period. The VLAN template disables routing in hardware. You can configure ports or EtherChannels in any VLAN as SPAN sources. What is a cause for this issue? A. However. Choosing the VLAN template will actually disable routing (number of entry for unicast or multicast route is zero) in hardware. This gives the offending issue a chance to be cleared by the user (for example. D. VLAN filters are required to ensure traffic mirrors effectively. The SDM VLAN template causes the MAC address-table to overflow. but not a destination. by removing an unapproved device) without the need for administrative intervention.

You can configure IP source guard with source IP address filtering or with source IP and MAC address filtering. The interfaces are configured as Layer 3 using the no switchport command. Correct Answer: B Section: (none) Explanation Explanation/Reference: Explanation: IP source guard is a security feature that restricts IP traffic on nonrouted. the switch blocks all IP traffic received on the interface. The DHCP client interfaces have storm control configured. After IP source guard is enabled on an interface. C. The MAC address in the DHCP packet is not learned as a secure address. The MAC address of the DHCP client is learned as a secure address only when the switch receives non-DHCP data traffic. The port ACL allows only IP traffic with a source IP address in the IP source binding table and denies all other traffic. An entry in this table has an IP address. but is unable to configure ip verify source under several of the interfaces. Static DHCP bindings are not configured on the switch. there are two caveats: The DHCP server must support option 82. The switch uses the IP source binding table only when IP source guard is enabled. D. Layer 2 interfaces by filtering traffic based on the DHCP snooping binding database and on manually configured IP source bindings. Which option is the cause of this issue? A. The switch is configured for sdm prefer routing as the switched database management template. The IP source binding table has bindings that are learned by DHCP snooping or are manually configured (static IP source bindings). DHCP snooping must be enabled on all VLANs. 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. D. You can use IP source guard to prevent traffic attacks caused when a host tries to use the IP address of its neighbor. The local DHCP server is disabled prior to enabling IP Source Guard.

It would be prohibitively difficult to coordinate the configuration of UDLD on both ends of a link at the same time. The UDLD port is placed in the "unknown" state for 5 seconds until the next UDLD packet is received on the interface. Loop Guard F. an uplink group consists of the root port (which is forwarding) and a set of blocked ports. UplinkFast E.A. Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: By default. UDLD is disabled on all interfaces. The bidirectional status of "unknown" indicates that the port will go into the disabled state because it stopped receiving UDLD packets from its neighbor. We can enable UDLD globally on the device. An uplink group is a set of Layer 2 interfaces (per VLAN). This enables UDLD in normal mode. STP immediately replaces the root port with an alternative root port. B. When UDLD is finally enabled on the other end. QUESTION 22 A network engineer must adjust the STP interface attributes to influence root port selection. the status will transition to bidirectional. C. The uplink group provides an alternate path in case the currently forwarding link fails. UplinkFast provides fast convergence after a direct link failure and achieves load balancing between redundant Layer 2 links using uplink groups. 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. cost C. as it would with the normal spanning-tree procedures. PortFast C.

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
