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

VTP version 3 supports extended-range VLANs (VLAN numbers 1006 to 4094). Switch A. Ensure that all switches run the same Cisco IOS version. Extended VLANs will not propagate to different IOS versions when extended VLANs are in use. Make sure that if EtherChannels are created between two switches. D. VTP does not support extended VLANs and should be manually added to all switches. What should be configured for extended VLANs? A. the extended VLANs are not being propagated to other VTP switches.com/en/US/tech/tk389/tk689/technologies_tech_note09186a0080890613. VTP allows a consistent view of the switched network across all switches. Switch B is configured in transparent mode. What is the most probable cause of this behavior? A. You must configure extended-range VLANs manually on each network device.cisco. Make sure that no password is set between the server and client. Correct Answer: B Section: (none) Explanation Explanation/Reference: Explanation: VTP version 1 and VTP version 2 do not propagate configuration information for extended. only Layer 2 EtherChannels propagate VLAN information. make sure that the password is the same on both sides. C. There are several reasons why the VLAN information can fail to be exchanged.

The best explanation for why switch C is not seeing traffic from only some of the VLANs. The trunk between Switch A and Switch B is misconfigured. Switch B has all VLANs. What would cause this issue? A. C. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements.

This automatic link type setting can be overridden by explicit configuration. 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. These ports are allowed to immediately enter the forwarding state rather than passively wait for the network to converge. 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). Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: RSTP works by adding an alternative port and a backup port compared to STP. VTP pruning D. QUESTION 11 Which technique automatically limits VLAN traffic to only the switches that require it? A. it has been determined that several ports are not transitioning as they should. This makes them candidates for rapid transition to the forwarding state. while a half-duplex port is considered as a shared port by default. The link type is automatically derived from the duplex mode of a port. What is the reason for this? A. RSTP has been enabled per interface and not globally. After testing. The STP root bridge selection is forcing key ports to remain in non-rapid transitioning mode. C. This path is different than using the root port. access lists B.C. In switched networks today. a network administrator can manually disable a port. most links operate in full-duplex mode and are treated as point-to-point links by RSTP.

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
