QUESTION NO: 1

Refer to the exhibit. EIGRP has been configured on all routers in the network. What additional configuration statement should be included on router R4 to advertise a default route to its neighbors?

A. R4(config)# ip route 0.0.0.0 0.0.0.0 10.1.1.1

B. R4(config)# ip default-network 10.0.0.0

C. R4(config-router)# default-information originate

D. R4(config)# ip route 10.0.0.0 255.0.0.0 10.1.1.1

Answer: B

Explanation:

Unlike the ip default-gateway command, you can use ip default-network when ip routing is enabled on the Cisco router. When you configure ip default-network the router considers routes to that network for installation as the gateway of last resort on the router. For every network configured with ip default-network , if a router has a route to that network, that route is flagged as a candidate default route. Gateways of last resort selected using the ip default-network command are propagated differently depending on which routing protocol is propagating the default route. For IGRP and EIGRP to propagate the route, the network specified by the ip default-network command must be known to IGRP or EIGRP. This means the network must be an IGRP- or EIGRP-derived network in the routing table, or the static route used to generate the route to the network must be redistributed into IGRP or EIGRP, or advertised into these protocols using the network command. In this case, the 10.0.0.0 network is indeed being advertised via EIGRP. Reference: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094374.shtml#ipnetw ork

QUESTION NO: 2

Refer to the exhibit. Router RTA is the hub router for routers RTB and RTC. The Frame Relay network is configured with EIGRP, and the entire network is in autonomous system 1. However, router RTB and RTC are not receiving each other's routes. What is the solution?

Check and change the access lists on router RTA.

B. Configure the auto summary command under router eigrp 1 on router RTA.

C. Configure subinterfaces on the spoke routers and assign different IP address subnets for each subinterface.

D. Issue the no ip split horizon command on router RTA.

E. Issue the no ip split horizon eigrp 1 command on router RTA.

F. Configure a distribute list on router RTA that allows it to advertise all routes to the spoke routers.

Answer: E

Explanation:

Split horizon controls the sending of EIGRP update and query packets. When split horizon is enabled on an interface, these packets are not sent for destinations for which this interface is the next hop. This reduces the possibility of routing loops. By default, split horizon is enabled on all interfaces. Split horizon blocks route information from being advertised by a router out of any interface from which that information originated. This behavior usually optimizes communications among multiple routing devices, particularly when links are broken. However, with nonbroadcast networks (such as Frame Relay and SMDS), situations can arise for which this behavior is less than ideal. For these situations, you may want to disable split horizon. In this example, routes received by RTB and RTC are not being sent back out the same serial interface on RTA, so they are not receiving

each other's routes. Disabling Split horizons on interface S0/0 on RTA will fix this issue.

QUESTION NO: 3

Refer to the exhibit. EIGRP is configured on all routers in the network. On a basis of the show ip eigrp topology output provided, what conclusion can be derived?

A. Router R1 is waiting for a reply from the neighbor 10.1.2.1 to the hello message sent out inquiring for a second successor to network 10.6.1.0/24.

B. Router R1 can send traffic destined for network 10.6.1.0/24 out of interface FastEthernet0/0.

C. Router R1 is waiting for a reply from the neighbor 10.1.2.1 to the hello message sent out before it declares the neighbor unreachable.

D. Router R1 is waiting for a reply from the neighbor 10.1.2.1 in response to the query sent out about network 10.6.1.0/24.

Answer: D

Explanation:

The "show ip eigrp topology" command lists all routes that EIGRP is aware of and shows whether EIGRP is actively processing information on that route. Under most normal conditions, the routes should all be in a passive state and no EIGRP process are running for that route. If the routes are active, this could indicate the dreaded stuck in active, or SIA, state. The fields to note in this output are as follows: P- Passive; no EIGRP computation is being performed. This is the ideal state. A- Active; EIGRP computations are "actively" being performed for this destination. Routes constantly appearing in an active state indicate a neighbor or query problem. Both are symptoms of the SIA problem. U- Update; an update packet was sent to this destination. Q- Query; a query packet was sent to this destination. R- Reply; a reply packet was sent to this destination. Route information- IP address of the route or network, its subnet mask, and the successor, or next hop to that network, or the feasible successor.

QUESTION NO: 4

Refer to the exhibit. Which three statements are true? (Choose three.)

S 62.99.153.0/24 [1/0] via 209.177.64.130 172.209.12.0/32 is subnetted, 1 subnets D EX 172.209.1 [170/2590720] via 209.179.2.114, 06:47:28, Serial0/0/0.1239 62.113.17.0/24 is variably subnetted, 2 subnets, 2 masks D EX 99.3.215.0/24 [170/27316] via 209.180.96.45, 09:52:10, FastEthernet11/0/0 [170/27316] via 209.180.96.44, 09:52:10, FastEthernet11/0/0 25.248.17.0/24 [90/1512111] via 209.179.66.25, 10:33:13, Serial0/0/0.1400001 [90/1512111] via 209.179.66.41, 10:33:13, Serial0/0/0.1402001 62.113.1.0/24 is variably subnetted, 12 subnets, 2 masks D 62.113.1.227/32 [90/2611727] via 209.180.96.45, 10:33:13, FastEthernet1/0/0 [90/2611727] via 209.180.96.44, 10:33:13, FastEthernet1/0/0 S* 0.0.0.0/0 [1/0] via 209.180.96.14

A. An EIGRP route will go active if there are no successors or feasible successors in the EIGRP topology table.

B. An EIGRP route will go passive if there are no successors in the EIGRP topology table.

C. DUAL will trigger an EIGRP query process while placing the flapping routes in the holddown state.

D. A feasible successor in the EIGRP topology table can become the successor only after all the query requests have been replied to.

E. The stuck in active state is caused when the wait for the query replies have timed out.

F. EIGRP queries are sent during the loading state in the EIGRP neighbor establishment process.

Answer: A,E

QUESTION NO: 8

What are three key concepts that apply when configuring the EIGRP stub routing feature in a hub and spoke network? (Choose three.) Select 3 response(s).

A. A hub router prevents routes from being advertised to the remote router.

B. Only remote routers are configured as stubs.

C. Stub routers are not queried for routes.

D. Spoke routers connected to hub routers answer the route queries for the stub router.

E. A stub router should have only EIGRP hub routers as neighbors.

F. EIGRP stub routing should be used on hub routers only.

Answer: B,C,E

QUESTION NO: 9

Based on the exhibited output, which three statements are true? (Choose three.)

A. All the routes are in the passive mode because R1 is in the query process for those routes.

B. R1 is in AS 200.

C. R1 will load balance between three paths to reach the 192.168.1.48/28 prefix because all three paths have the same advertised distance (AD) of 40512000.

D. 40512000 is the advertised distance (AD) via 192.168.1.66 to reach the 192.168.1.48/28 prefix.

E. All the routes are in the passive mode because these routes are in the hold-down state.

F. The best path for R1 to reach the 192.168.1.48/28 prefix is via 192.168.1.66.

Answer: B,D,F

Explanation:

It can be determined that AS 200 is used, from the fact that the IS-IS process ID is labeled as 200. The best path to reach the network 192.168.1.48/28 is the first one displayed in the routing table. This can be further demonstrated by the fact that the metric is less than the alternative route, via serial 0. Finally, the AD can be found by viewing the second number within the parentheses, which in this case is 40512000.

QUESTION NO: 10

Refer to the exhibit. EIGRP is configured with the default configuration on all routers. Auto summarization is enabled on routers R2 and R3, but it is disabled on router R1. Which two EIGRP routes will be seen in the routing table of router R3? (Choose two.)

Answer: D,E

QUESTION NO: 11

Refer to the exhibit. EIGRP has been configured on routers R1 and R2. However, R1 does not show R2 as a neighbor and does not accept routing updates from R2. What could be the cause of the problem?

Cisco 642-902: Practice Exam

A. The no auto-summary command has not been issued under the EIGRP process on both routers.

B. Interface E0 on router R1 has not been configured with a secondary IP address of 10.1.2.1/24.

C. EIGRP cannot exchange routing updates with a neighbor's router interface that is configured with two IP addresses.

D. EIGRP cannot form neighbor relationship and exchange routing updates with a secondary address.

Answer: D

QUESTION NO: 12

Which EIGRP packet statement is true?

A. Update packets route reliable change information only to the affected routers.

B. Reply packets are multicast to IP address 224.0.0.10 using RTP.

C. On high-speed links, hello packets are broadcast every 5 seconds for neighbor discovery.

D. Reply packets are used to send routing updates.

E. On low-speed links, hello packets are broadcast every 15 seconds for neighbor discovery.

Answer: A

QUESTION NO: 13

EIGRP has been configured to operate over Frame Relay multipoint connections. What should the bandwidth command be set to?

A. the CIR rate of the lowest speed connection multiplied by the number of circuits

B. the CIR rate of the lowest speed connection

C. the CIR rate of the highest speed connection

D. the sum of all the CIRs divided by the number of connections

Answer: A

Explanation:

If the multipoint network has different speeds allocated to the VCs, take the lowest CIR and simply multiply it by the number of circuits. This is because in Frame-relay all neighbors share the bandwidth equally, regardless of the actual CIR of each individual PVC, so we have to get the lowest speed CIR rate and multiply it by the number of circuits. This result will be applied on the main interface (or multipoint connection interface).

QUESTION NO: 14

QUESTION NO: 20

Which three statements are true about EIGRP route summarization? (Choose three.)

A. When manual summarization is configured, the router immediately creates a route that points to null0 interface.

B. Manual route summarization is configured in router configuration mode when the router is configured for EIGRP routing.

C. Manual route summarization is configured on the interface.

D. The ip summary-address eigrp command generates a default route with an administrative distance of 5.

E. When manual summarization is configured, the summary route will use the metric of the largest specific metric of the summary routes.

F. The ip summary-address eigrp command generates a default route with an administrative distance of 90.

Answer: A,C,D

Explanation:

The purpose of route summarization is small routing tables, smaller updates. On major network boundaries, subnetworks are summarized to a single classful network and automatic route summarization is enabled by default. Manual route summarization can be configured on per interface basis. When summarization is configured on an interface, the router immediately creates a route pointing to null0. Route summarization works in conjunction with the ip summary-address eigrp interface configuration command, in which additional summarization can be performed. If automatic summarization is in effect, there usually is no need to configure network level summaries using the ip summary-address eigrp command. You can configure a summary aggregate address for a specified interface. If there are any more specific routes in the routing table, EIGRP will advertise the summary address out the interface with a metric equal to the minimum of all more specific routes.

Cheap N routers vs G Routers for Sales

There are two types of wireless routers in ther market, you're likely to come across when shopping around for a broadband deal and it is true that which one is better suited to your needs than another.
Wireless routers and the WiFi networks they broadcast work using the 802.11 standard and like all things technological this standard is constantly being worked upon and improved to keep up with the demands of new applications.
The 802.11g version of wireless networking, recognisable as a 54Mbps wireless router or 'G-router', is the current workhorse and is built into the routers given away by most broadband providers
G-Router speed is 54Mbps,
N-router Speed is 108, 150, and 300Mbps.

N router is more better at same Price.

Scientists say electrons are spectacularly round

2011-05-30T12:23:00.000-07:00

Scientists have found that electrons are basically perfect spheres.
So perfect that if the subatomic particle were blown up to be the size of our solar system, any imperfection would be less than the width of a human hair.
Put another way, any deviation of roundness would be less than a billionth of a billionth of a billionth of a centimeter across.
That’s mind-bogglingly round.
The six scientists at Imperial College London measured the electron’s roundness by training a measuring system of red and green lasers on a special molecule orbited by a single electron. They then put the molecule in an electrically charged place and looked to see if the electron would wobble.
Just as an egg placed on your dining table would flop over, an imperfectly round electron would be expected to flop over, or wobble.
They ran this experiment 25 million times and blinded themselves from its results until after the 25 millionth run of the experiment so they would not be biased in interpreting the results.
The Guardian, quoting researcher Jony Hudson, reported,

They found no sign of the electron wobbling in the field, meaning it is more spherical than any previous experiment had shown. “To the best of our knowledge, with the experimental precision we have, the electron appears to be round,” Hudson said.

Their results, published in Nature, call into question theories that posit the electron is not perfectly round. A slightly aspherical electron would help explain why antimatter has disappeared since the Big Bang created the universe 12 to 14 billion years ago. An imperfectly round electron could also provide proof for a relatively new theory of physics called supersymmetry in which the particles of nature must come in pairs.
This recent finding could be a blow to the theory of supersymmetry, but even more precise measurements are necessary, because the electron could be egg-shaped at a scale smaller than this experiment examined.
Nature, quoting lead researcher Edward Hinds, reported,

Hinds reckons that by increasing the number of molecules per pulse and reducing their speed, his group should be able to raise the sensitivity of measurement by a factor of ten “over the next few years”, and, ultimately, by a factor of 100. … “We would pretty much rule out all current theories if we went down by a factor of 100 and saw nothing,” he says.
