Answer A, B, C, D. Virtual LANs are a group of devices on one or more LANs that are configured (using management software) so that they can communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments. Because VLANs are based on logical instead of physical connections, they are extremely flexible.
87. What is the IEEE specification for Spanning Tree?
A. 802.2u B. 802.3q C. 802.1d D. 802.6
Answer C. SPT is a bridge protocol that utilizes the spanning-tree algorithm, enabling a learning bridge to dynamically work around loops in a network topology by creating a spanning tree. Bridges exchange BPDU messages with other bridges to detect loops, and then remove the loops by shutting down selected bridge interfaces. Refers to both the IEEE 802.1d Spanning-Tree Protocol standard and the earlier Digital Equipment Corporation Spanning-Tree Protocol upon which it is based. The IEEE version supports bridge domains and allows the bridge to construct a loop-free topology across an extended LAN. The IEEE version is generally preferred over the Digital version. Sometimes abbreviated STP
88. Of the three switching types, which one has the lowest latency?
A. Cut-through B. FragmentFree C. Store-and-forward D. None
Answer A. Cut-through packet switching streams data through a switch so that the leading edge of a packet exits the switch at the output port before the packet finishes entering the input port. A device using cut-through packet switching reads, processes, and forwards packets as soon as the destination address is looked up, and the outgoing port determined. Also known as on-the-fly packet switching. Since no error checking takes place, it has the lowest latency.
89. Of the three switching types, which one has the highest latency?
A. Cut-through B. FragmentFree C. Store-and-forward D. None
Answer C. Store-and-forward packet-switching technique in which frames are completely processed before being forwarded out the appropriate port. This processing includes calculating the CRC and checking the destination address. In addition, frames must be temporarily stored until network resources (such as an unused link) are available to forward the message. Since frame size can very in length, latency will then vary.

Answer B. 224.0: 11100000.00000000: 224 gives us three bits, or six subnets, each with 8190 hosts.240.0: 11110000.00000000: 240 gives us four bits, or 14 subnets, each with 4094 hosts.248.0: 11111000.00000000: 248 gives us five bits, or 30 subnets, each with 2046 hosts.252.0: 11111100.00000000: 252 gives us six bits, or 62 subnets, each with 1022 hosts.By using only eight subnets, we can use 240.0 as a mask, giving us 14 subnets, each with 4094 hosts.
102. You have a Class A network address with 60 subnets. You need to add 40 new subnets in the next two years, but still allow for the largest possible number of host IDs per subnet. Which subnet mask should you assign?
A. 255.240.0.0 B. 255.248.0.0 C. 255.252.0.0 D. 255.254.0.0
Answer D. 240.0.0: 11110000.00000000.00000000: 240 gives us four bits, or 14 subnets, each with 1,048,574 hosts.248.0.0: 11111000.00000000.00000000: 248 gives us five bits, or 30 subnets, each with 524,286 hosts.252.0.0: 11111100.00000000.00000000: 252 gives us six bits, or 62 subnets, each with 262,142 hosts.254.0.0: 11111110.00000000.00000000: 254 gives us seven bits, or 126 subnets, each with 131,070 hosts. Only mask 254.0.0 gives us the amount of subnets we need to allow for maximum growth.
103. You have a Class C network address of 192.168.19.0 with four subnets. You need the largest possible number of host IDs per subnet. Which subnet mask should you assign?

104. You need to come up with a TCP/IP addressing scheme for your company. How many network IDs must you allow for when you define the subnet mask for the network?
A. One for each subnet B. One for each host ID C. One for each router interface D. One for each WAN connection
Answer A D. Each host on the network must have a unique IP address. However, you are required to have only one network ID per network. Each set of hosts must share a common network ID, as well as connections between networks, which are the WAN connections.
105. You need to come up with a TCP/IP addressing scheme for your company. Which two
factors must you consider when you define the subnet mask for the network?
A. The number of subnets on the network B. The number of host IDs on each subnet C. The volume of network traffic on each subnet D. The location of DNS servers E. The location of default gateways
Answer A, B. When deciding on an IP scheme, you need to understand the amount of subnets and the amount of hosts per subnet.
106. You need to come up with a TCP/IP addressing scheme for your company. How many host IDs must you allow for when you define the subnet mask for the network?
A. One for each subnet B. One for each router interface C. One for each WAN connection D. One for each network adapter installed on each host
Answer B D. Host ID are not just PC's, MAC's and Unix stations. Anything that has an interface is host or network device.
107. You have an IP address of 172.16.13.5 with a 255.255.255.128 subnet mask. What is your class of address, subnet address, and broadcast address?

Answer D. Class B, Subnet 13, Broadcast address 172.16.13.127. The valid range for hosts is 172.16.13.1 to 172.16.13.126.
108. If you have a 22-bit subnet mask, how many subnets and how many hosts do you have?
A. 8190 subnets, 4096 hosts B. 4,194,302 subnets, 2 hosts C. 2,096,138 subnets 6 hosts D. 16,384 subnets, 2046 hosts
Answer B. A 22-bit subnet mask would be 255.255.255.252. On the Cisco test, they do not count the default mask. The only class of address that could take a 22-bit mask is a class A. Start with 255 and add 22 bits. This gives you two bits for the hosts, or 2 hosts per subnet.
P.S You know this is not the only dump site so if you would take the time to look around instead of bitching that there is no dumps on SASA's site.

Greetings all, I passed this test earlier this week and had mixed feelings. Around the 10th question, I was thinking... "damn, I'm gonna fail." But as I continued with the test I noticed that most of the questions were based on pretty general networking theory and common practices. For instance one question asked: "What is the maximum distance for a 100baseTx segment?". And I had the ever so famous router question: "What device provides the greatest security between two segments?"
Then there were the OSI and Subnetting questions. No, you CANT use a calculator. Folks, I hate to sound cruel but you should know how to do this by heart. And you should know the OSI layers just as well.
Finally there are the actual Cisco related questions.... CLI questions, Access lists, RIP, IGRP, CDP, etc.... which is essentially the other half of the test.
I studied about 1 month for this test. I used the Cisco Prep Library for the 507, I had telnet access to my buddies 3 router lab, and I also had all 3 Boson tests (for the 507), Troytec, and Sybex Lammele. You can forget about Sybex, IMO, the Cisco books were far better. Troytec is an excellent point to point summary to use for last minute cramming. Boson was good for drilling questions... all 3 tests you can have about 600-700 questions... though many are duplicates. PLEASE DO NOT EMAIL ME ASKING FOR BOSON OR TROYTEC. I paid for these out of my pocket... please respect that decision.
Now that brings me to another point. If you are taking Cisco exams, you should realize that it is a career move toward a more elite arena of the IT world. What I mean is.... If you are going to submit a dump. then that's fine. DUMP. But respect other people's decision to NOT DUMP. I'm sick and tired of people whinning that they failed because they used a braindump or book that someone else swore would be all they needed to pass.
Dont get me wrong though, I USED to be a BIG fan of braindumps. Till I realized that I am only cheating myself. Case in Point: Through braindumps, I am a MCDBA. But do I feel I have the adequate knowledge to be an actual DBA? Nope.
I refuse to do the same with Cisco Products and Certification. I'm all for "self study" and saving money on certification material.... but for arguments sake, would rather learn this material from Cisco Press books and actual labs/routerism from here on.

Before I submit my 3 page dump, I have to ask why people bother submitting their comments without any dumps? I thougt that this was what this site was for? Your comments on how hard it was does not really help anybody now does it? Anyway here is my dump. I had a lot of these questions here so enjoy.
CCNA 2.0 BRAINDUMP
(1) Purpose of Spanning tree? Maintain loop free network, IEEE 802.1d, enabled by default (2) How frames are transmitted? Store and forward, cut through, fragment-free (3) How does full-duplex improve network performance? Using point to point Ethernet and fast Ethernet connections. In full, the collision detect is disabled. Nodes attached to hubs or nodes sharing their connection with a switch port must operate in half to detect collisions.

Verifies IP address, etc for the switch (7) Output of Show Version? Displays switch hardware and IOS information. (8) Copy configuration files to TFTP server (what command)? Copy nvram tftp://host/dst_file (9) What is a VLAN? A logical broadcast domain that can span multiple physical LAN segments. Can be segmented by functions, project teams or application. VLAN'S enable switches to create multiple broadcast domains within a switched network. (10) What are the 2 types of routes? Static and dynamic (11) What is ISL Tagging? A Cisco proprietary used to interconnect multiple switches and to maintain VLAN information as traffic goes between switches. Each device must be ISL capable. ISL functions at layer 2 of the OSI. (12) What modes does VTP operate at? Server (default), client and transparent. A man of 64 VLAN'S can be active on most desktops. (13) How to display Spanning-tree configuration? Switch# show spantree 1 (14) Purpose of 3-way handshake? Error control (15) Flow control for tcp/udp? Uses window size (flow control mechanism) to determine how many bytes the receiver can accept (16) TCP/IP internet layer protocols? IP, ICMP, ARP, RARP (determines source network ip addresses when source data link layer address are known. ICMP is implemented by all TCP/IP hosts. Most common form included pings, echo request and echo replies. ARP resolves ip addresses to MAC address.

Flooded broadcasts (255.255.255.255) are not propagated because they are considered local. To broadcast a message within a single subnet the host portion of the address contains all 1's. Broadcasts directed into a specific network are allowed and forwarded by the router. These contain all 1's in the host portion of the IP address. To broadcast messages to all hosts on all subnets within a single network, the host and subnet portions of the address all contain 1's (pg 232 in ICND book). (20) Subnet planning questions (page 235 ICND) book (21) How to assign a router interface logical network address? Router (config-if)# ip address (22) How do you get rid of hold-down timers?

Amount of memory on router, amount of memory available, name and size of Image file (55) Switches - Segment network into multiple collision domains. Have 3 functions - address learning - packet forwarding/filtering - loop avoidance. Operates as a transparent bridge (uses MAC address to locate device locations connected to switch. (56) What are valid numbers for a sub-interface? RTR1(config)# interface serial2 (57) enabling RIP on a router? Router (config)# router rip (58) What are 2 ways to tell the router where to forward packets that are not directly connected? Static and dynamic routes.

Cisco, ansi, q933a
I had 4 subnetting questions also. The test is poorly worded. Good luck everyone!!!!!
small dump
640-507

For those of you who have been looking for dumps: Forget it! They don't seem to exist or people are reluctant to create them. Troy technologies is not a good study guide, save yourselves the 39 bucks. Out of the 300 questions the give you only ten or fifteen of them we on the exam. It's a waste of time. Study something else. For a router simulator go to routeru.com. They also have a study guide (Adobe) that isn't too shaby. Everyone seems to love Lammie's book. Perhaps, I should have purchased that one, bit I bought the big, oversized Odom CISCO CCNA guide. It's not really that great.
I've found that the old Transcender test (407) has a lot of questions word for word. The Boson tests? Never tried them but have heard good things. I'm going to take the test again on Friday and if I don't pass it that time, then forget it. I really don't work with CISCO products directly at all. It was just something to put on my resume'. I've already put way too much time in studying this stuff. Here's some general testing strategy and a dump. Yes actually a dump on this webpage of 30 posts and no dump. It's short, but sweet. But after 30 posts I haven't seen one dump, so here's some stuff it's probably the best post on the board so far. What does [] mean? How do you show the parameters of a command? ans: command (space) ? What do bridges do? forward broadcasts How do you enable RIP? The exam will not give you multiple choice, but rather a space to type in the answer. How do you enable IPX routing? " " " " " How do you enable IP routing? " " " " " What is the max. distance of 10baseT? 100 METERS What is the max. distance of 100baseT? same What is frame tagging? What is frame relay? There's a few questions on it. Know it. What does BOOT SYSTEM ROM do? directs the Cisco router to boot the IOS from ROM. How do you continue your connection while opening up another screen? ctrl+alt+X How a ping command should look? #ping ip address How do you upgrade IOS? How to enable access lists? A question able area hierachies? How does a succesful ping look?
These questions may be paraphrased, but this if what I remember from the test. These are on it and they are worth verifying them and familiarizing yourself with them.
Test Strategy:
1)Forget IP subnetting stuff. It usually takes a long time to learn. Troy Technologies suggested memorizing the entire subnet table in one of their study guides. It took an hour and a half to memorize and I never used it on the exam. It took 20 minutes to recreate it during the test and it was a waste of time. There's only 3 questions on subnetting. Knowing the default subnets for the different classes is essential and worthwhile. Know how to differentiate the node from the network.
2) Know IOS commands inside and out. Someone posted that the test is over 50 percent commands. That is not far from the truth.
3) Know switches and LAN. Much of the study material out there doesn't emphasis this enough. Bridges and switches really play a part.
4) You need a general hands-on networking knowledge. As I have stated previously there are a void of braindumps. This causes the certificate much harder to obtain. As it is Cisco test are much
harder than Microsoft's 4.0 track so you may really want to consider whether you want to go ahead and study this stuff and if it's necessary to your job role.
5) CRAM, CRAM, CRAM...all these IT certification test are short term memory stuff. I'm an MCSE and I only remember maybe %50 of the questions that I was tested on. It's like taking Spanish in high school. I can remeber only the stuff that I currently use. Since it is all short term place everything in that little head of yours and take Lecithin for the week before your exam. Lecithin is a dietary supplement that increases your memory by enhancing your neurotransmitters. Some opt for taking some caffeine before the test. Know thyself...if caffeine only gives you the jitters, don't take it, but if it increases your awareness, then do it.
