QUESTION 105 Which statement about Root Path Cost is true?
A. It is the Path Cost of a particular Root Port.
B. It is the cost sent from the Root Bridge to all non-Root bridges.
C. This value is the cumulative cost of all the links leading to the Root Bridge.
D. This value is the cumulative cost of all links sent from the Designated Port of the Root Bridge. Answer: C Explanation: http://www.trinhtechnologies.com/ccnp_switching.htm There are two factors involved in the root port selection:
. Path Cost, which is the sum of all links crossed to get to the root bridge that incurs the lowest path cost when
forwarding a frame from a segment to the root bridge. Only one designated bridge for each LAN. The bridge has the least root path cost to the root bridge. If two bridges have the same root path cost, choose the highest-priority bridge as the designated bridge. It is the only bridge that allows to forward frames. The root bridge is always the designated bridge for all the segments connected to it.

QUESTION 115 Network topology exhibit: A service provider is currently providing services to Enterprise Cisco Highway.com. Enterprise Cisco Highway.com is supporting VLANs with the range of 1 to 15. Enterprise Acme.com has recently requested support from the service provider and is currently configured to support VLANs with the range of 1 to 25. Which Layer 2 technology should the service provider use to that traffic stays segmented and Enterprise Cisco Highway.com and Enterprise Acme.com can maintain their current VLAN configurations?
A. Transparent LAN services
B. Metro Ethernet over DWDM
C. 802.1Q in Q
D. EoMPLS
E. L2TPv3Answer: B Explanation: VLAN tunneling in the metro environment allows customers to extend their logical network topology across wide geographic areas. This comes into play especially when VoIP technologies are implemented. Without VLAN tunneling, customers are forced to renumber their existing VLANs, or the service provider is forced to provide some sort of VLAN translation at the access point to support multiple customers with overlapping VLAN numbers. However, through DWDM and separate wavelength routing solutions, each customer is completely segmented from the others, allowing complete autonomy.
QUESTION 116 What is the cause of jitter?
A. Variable queue delays
B. Packet drops
C. Transmitting too many small packets
D. Compression Answer: A Explanation: Delay variation or jitter is the difference in the delay times of consecutive packets. A jitter buffer is often used to smooth out arrival times, but there are instantaneous and total limits on buffering ability. Any type of buffering used to reduce jitter directly increases total network delay. In general, traffic requiring low latency also requires a minimum variation in latency. Note: Jitter in Packet Voice Networks Jitter is defined as a variation in the delay of received packets. At the sending side, packets are sent in a continuous stream with the packets being spaced evenly apart. Due to network congestion, improper queuing, or configuration errors, this steady stream can become lumpy, or the delay between each packet can vary instead of remaining constant.
QUESTION 117 How is the designated queries elected in IGMPv2?
A. The first router to appear on a subnet is designated.
B. The host that responds first to the election query is designated.
C. The router with the lowest IP address on subnet is designated.
D. The host with the lowest MAC address on a segment is designated. Answer: B Explanation: Unlike IGMP Version 1, in which the DR and the IGMP queried are typically the same router, in IGMP Version 2, the two functions are decoupled. The DR and the IGMP queried are selected based on different criteria and may be different routers on the same subnet. The DR is the router with the highest IP address on the subnet, whereas the IGMP queried is the router with the lowest IP address.
QUESTION 118 Which two statements are true about implementing QoS at the access, distribution, or core layer? (Choose two)
A. QoS implementation is the same for the access, distribution, and core layers.
B. Classification and Marking should be done at the access layer.
C. No QoS mechanisms are configured at the access layer since access layer switches like the Catalyst 2950 are not QoS capable.
D. The high speed core layer only requires proper queuing (like LLQ) and dropping (like WRED) configurations. Answer: B, D Explanation: You typically want to classify and mark traffic as close to source as possible typically access layer unless you have server farms that are grouped at distribution layer)
QUESTION 119 How does a Layer 2 switch handle multicast traffic, by default?

C. Only router ACLs can be applied to a VLAN interface.
D. VLAN maps can be applied to a VLAN interface.
E. VLAN maps and router ACLs can be used in combination. Answer: A, B, E Explanation: Router ACLs are applied on interfaces as either inbound or outbound. To filter both bridged and routed traffic, VLAN maps can be used by themselves or in conjunction with router ACLs. VLAN ACLs, also called VLAN maps, filter both bridged and routed packets. VLAN maps can be used to filter packets exchanged between devices in the same VLAN.

QUESTION 126 When you issue a command show port 3/1 on an Ethernet port, you observe the Giants column has a nonzero entry. What could cause this?
A. IEEE 802.1Q
B. IEEE 802.10
C. Misconfigured NIC
D. User configuration Answer: A Explanation: The 802.1Q standard can create an interesting scenario on the network. Recalling that the maximum size for an Ethernet frame as specified by IEEE 802.3 is 1518 bytes, this means that if a maximum-sized Ethernet frame gets tagged, the frame size will be 1522 bytes, a number that violates the IEEE 802.3 standard. To resolve this issue, the 802.3 committee created a subgroup called 802.3ac to extend the maximum Ethernet size to 1522 bytes.

A. Internet Protocol address
B. Media Access Control address
C. Packet Layer Protocol address
D. Network Service Access Point address
E. Authority and Format Identifier address Answer: D Explanation: Network Layer Addressing OSI network layer addressing is implemented by using two types of hierarchical addresses: network service access point addresses and network entity titles. A network service access point (NSAP) is a conceptual point on the boundary between the network and the transport layers. The NSAP is the location at which OSI network services are provided to the transport layer. Each transport layer entity is assigned a single NSAP, which is individually addressed in an OSI internetwork using NSAP addresses.

QUESTION 1 According to Cisco, the point of MLS is to:
A. Create a bridge between two VLANs
B. Create an encrypted session between two VLANs
C. Create a secure channel between two VLANs
D. Create a shortcut between two VLANs Answer: D Explanation: According to Cisco: It is a basic topology requirement of MLS that the router have a path to each of the VLANs. Remember that the point of MLS is to create a shortcut between two VLANs, so that the "routing" between the two end devices can be performed by the switch, thus freeing the router for other tasks. The switch is not actually routing; it is rewriting the frames so that it appears to the end devices that they are talking through the router. If the two devices are in the same VLAN, then the MLS-SE will switch the frame locally without utilizing MLS, as switches do in such a transparently bridged environment, and no MLS shortcut will be created. One can have multiple switches and routers in the network, and even multiple switches along the flow path, but the path between the two end devices for which one desires an MLS shortcut must include a single MLS-RP in that VLAN for that path. In another words, the flow from source to destination must cross a VLAN boundary on the same MLS-RP, and a candidate and enabler packet pair must be seen by the same MLS-SE for the MLS shortcut to be created. If these criteria are not met, then the packet will be routed normally without the use of MLS.
QUESTION 2 At what state will a HSRP-configured router be performing packet transfer function?
A. Listening
B. Active
C. Standby
D. Queuing
E. Waiting
F. Speaking and listening Answer: B Explanation: According to the online documentation provided by Cisco: At any time, HSRP-configured routers are in one of the following states: Active-The router is performing packet-transfer functions. Standby-The router is prepared to assume packet-transfer functions if the active router fails. Speaking and listening-The router is sending and receiving hello messages. Listening-The router is receiving hello messages.
QUESTION 3 Which of the following correctly describe the MLS-SE?
A. It is a switch with special MLS IOS.
B. It is a switch with special hardware.
C. It is a switch with no special hardware.
D. It is a switch with special software. Answer: B Explanation: According to Cisco: The MLS-SE is a switch with special hardware. For a member of the Catalyst 5000 family, MLS requires that the supervisor have a Netflow Feature Card (NFFC) installed. The Supervisor IIG and IIIG have one by default. In addition, a bare minimum of Catalyst OS 4.1.1 software is also required. Note that the 4.x train is now in General Deployment (GD), or passed rigorous end-user criteria and field-experience targets for stability, so check Cisco's website for the latest releases. IP MLS is supported and automatically enabled for Catalyst 6000 hardware and software with the MSFC/PFC (other routers have MLS disabled by default). Note that IPX MLS and MLS for multicasting may have different hardware and software (Cisco IOS and Catalyst OS) requirements. More Cisco platforms do/will support the MLS feature. Also, MLS must be enabled in order for a switch to be an MLS-SE.
QUESTION 4 When you configure a switch as the secondary root, the spanning tree bridge priority is modified from the default value to (fill in the blank): Answer: 16384 Explanation: According to Cisco: When you configure a switch as the secondary root, the spanning tree bridge priority is modified from the default value (32768) to 16384. This means that the switch is likely to become the root bridge for the specified VLANs if the primary root bridge fails (assuming the other switches in the network use the default bridge priority of 32768).
QUESTION 5 Which of the following is true about the 80/20 rule (Choose all that apply)?

QUESTION 6 VTP-capable devices can be configured to operate in which of the following modes such that a full list of all VLANS can be maintained?
A. VTP Bypass
B. VTP Client
C. VTP Transparent
D. VTP Restore E. VTP Server Answer: BE Explanation: According to the online documentation provided by Cisco: VTP-capable devices can be configured to operate in the following three modes: The VTP Server maintains a full list of all VLANs within the VTP domain. Information is stored in nonvolatile random-access memory (NVRAM). The server can add, delete, and rename VLANs. The VTP Client also maintains a full list of all VLANs. However, it will not store in NVRAM. The client can not add, delete, or rename VLANs. Any changes made must be received from a VTP server advertisement. The VTP Transparent does not participate in VTP. However, it will pass on a VTP advertisement. VLAN, as defined, is only local to the switch and is stored in NVRAM.

QUESTION 9 Refer to the exhibit: Warning: Spantree port fast start should only be enabled on ports connected to a single host. Connecting hubs, concentrators, switches, bridges, etc. to a fast start port can cause temporary spanning tree loops. Use with caution. Spantree ports 4/1-24 fast start enabled. What command produces this output (fill in the blank): Answer: set spantree portfast 4/1-24 enable Explanation: According to Cisco:
This setting should be configured only on ports that are connected to workstations or PCs. Do not enable portfast on any port connected to another switch.
QUESTION 10 STP prevents loop by forcing certain redundant data paths into a standby (blocked) state, while leaving others in a forwarding state.
A. False
B. True
C. There is not enough information to determine Answer: B Explanation: According to Cisco: STP forces certain redundant data paths into a standby (blocked) state, while leaving others in a forwarding state. If a link in forwarding state becomes unavailable, STP reconfigures the network and reroutes data paths by activating the appropriate standby path.

QUESTION 13 You are a Cisco Certified Engineer. You are configuring a switching solution. You need to find ways to conveniently manage your Catalyst Token Ring switches. Which of the following are NOT the Token Ring extensions available to the Remote Network Monitoring MIB (Choose all that apply)?
A. Sub-MAC Layer Address IDs
B. Promiscuous Statistics Group
C. Sub-MAC Layer Address Group
D. Sub-MAC Layer Group E. MAC-layer Statistics Group Answer: A, C, D Explanation: According to Cisco: As an option, the Catalyst Token Ring switches provide RMON support for statistics, history, alarms, and events. They also provide support for the following groups of the Token Ring extensions to the Remote Network Monitoring MIB (RFC 1513): MAC-layer Statistics Group--Collection of MAC-layer statistics kept for each Token Ring interface, such as the total number of MAC packets received and the number of times the port entered a beaconing state. Promiscuous Statistics Group--Collection of promiscuous statistics kept for non-MAC packets on each Token Ring interface, such as the total number of good non-MAC frames received that were directed to an LLC broadcast address. Token Ring Station Group--The Catalyst Token Ring switches support the ringStationControlTable portion of the Token Ring Station Group. This support allows a Catalyst Token Ring switch to gather segment information from each ring segment to which it is attached. This segment information includes Ring State, Beacon Sender, Beacon NAUN, and Active Monitor MacAddress, as well as Control Order Changes. Token Ring Station Order Group--Listing of the order of stations on the monitored rings.
QUESTION 14 You are a Cisco Certified Engineer. You are configuring a switching solution. Which of the following statements do NOT correctly describe a trunk link (Choose all that apply)?
A. The trunk link belongs to a specific VLAN.
B. Multiple trunk links are used to connect multiple devices.
C. A trunk link only supports native VLAN.
D. Trunk links use 802.10 to identify a VLAN.
E. The native VLAN of the trunk link is the VLAN that the trunk uses if that link fails for any reason. Answer: A, B, C, D Explanation: According to Cisco: trunk is a point-to-point link that transmits and receives traffic between switches or between switches and routers. Trunks carry the traffic of multiple VLANs and can extend VLANs across an entire network. 100BaseT and Gigabit Ethernet trunks use Cisco ISL (the default protocol) or industry-standard IEEE 802.1 QUESTION NO: to carry traffic for multiple VLANs over a single link. Frames received from users in the administratively-defined VLANs are identified or tagged for transmission to other devices. Based on rules you define, a unique identifier (the tag) is inserted in each frame header before it is forwarded. The tag is examined and understood by each device before any broadcasts or transmission to other switches, routers, or end stations. When the frame reaches the last switch or router, the tag is removed before the frame is transmitted to the target end station. More information can be found at: this site
QUESTION 15 MLS requires that MLS components be in the same Virtual Trunking Protocol domain.
A. False
B. There is not enough information to determine
C. True Answer: C Explanation: According to Cisco: MLS requires that MLS components, including the end stations, must be in the same Virtual Trunking Protocol (VTP) domain. VTP is a Layer 2 protocol used for managing VLANs on several Catalyst switches from a central switch. It allows an administrator to create or delete a VLAN on all switches in a domain without having to do so on every switch in that domain. The MultiLayer Switching Protocol (MLSP), which the MLS-SE and the MLS-RP use to communicate with one another, does not cross a VTP domain boundary.

QUESTION 20 When configuring STP, the root switch should be the:
A. most centralized switch
B. most secure switch
C. most updated switch
D. most powerful switch Answer: A Explanation: According to Cisco: Before configuring STP, you need to select a switch to be the root of the spanning tree. It does not necessarily have to be the most powerful switch; it should be the most centralized switch on the network. All dataflow across the network will be from the perspective of this switch. It is also important that this switch be the least disturbed switch in the network. The backbone switches are often selected for this function, because they typically do not have end stations connected to them. They are also less likely to be disturbed during moves and changes within the network.
QUESTION 21 What command do you use to find out whether the spanning tree Backbone Fast Convergence feature is enabled (CASE SENSITIVE fill in the blank): Answer: show spantree backbonefast Explanation: According to the online documentation provided by Cisco: Commands to Use for Troubleshooting The Configuration show spantree vlan_id - Shows the current state of the spanning tree for the "vlan_id" entered from the perspective of the switch on which it is entered. show spantree summary - Provides a summary of connected spanning tree ports by VLAN. show spantree statistics - Shows spanning tree statistical information. show spantree backbonefast - Displays whether the spanning tree Backbone Fast Convergence feature is enabled. show spantree blockedports - Displays only the blocked ports. show spantree portstate - Determines the current spanning tree state of a Token Ring port within a spanning tree. show spantree portvlancost - Shows the path cost for the VLANs on a port. show spantree uplinkfast - Shows the uplinkfast settings.

B. show ip rp [group-name group-address] [mapping]
C. show ip pim rp [group-name group-address] [mapping]
D. show ip rp pim [group-name group-address] [mapping] Answer: C Explanation: "Show ip mroute [Hostname Group]" is used to display the multicast routing table.
QUESTION 24 According to Cisco, the thing to remember in the STP root selection process is that:
A. smaller is better.
B. larger is better.
C. Ids should be all zeros Answer: A Explanation: According to Cisco: The thing to remember in the STP root selection process is that smaller is better. If the Root ID on Switch A is advertising it is smaller than the Root ID that its neighbor (Switch B) is advertising, Switch A's information is better. Switch B stops advertising its Root ID, and instead accepts that of Switch A.
QUESTION 25 You cannot create VLANs on a VTP server until:
A. the VTP server ID is cleared
B. the VTP membership list is refreshed
C. the priority is cleared
D. the management domain name is specified Answer: D Explanation: According to Cisco: By default, the switch is in VTP server mode and is in the no-management domain state until the switch receives an advertisement for a domain over a trunk link or you configure a management domain. You cannot create or modify VLANs on a VTP server until the management domain name is specified or learned.
QUESTION 26 If you configure VTP in secure mode, you must:
A. assign a management domain password to the VTP Server in the domain.
B. assign a management domain password to each switch in the domain.
C. assign a management domain password to the root switch in the domain. Answer: B Explanation: According to Cisco: If you configure VTP in secure mode, the management domain will not function properly if you do not assign a management domain password to each switch in the domain.
QUESTION 27 After you decide which switch should be the root switch, you need to set which variable such that this switch will be automatically selected by the other switches as the root switch (fill in the blank): Answer: bridge priority Explanation: According to Cisco: After you decide which switch should be the root switch, set the appropriate variables to designate it as the root switch. The only variable you have to set is the bridge priority. If this switch has a bridge priority that is lower than all other switches, it will be automatically selected by the other switches as the root switch.
