Feedbacks

I just came back from the exam with a score of 950 3 hours ago.

I got PPPOE simulation, 2 SDM similar in P4S, and also question 218 – 222 in P4S where it’s about site-to-site VPN which I’m curse myself for being panicked for a while( I believe i got ony 1 correct out of 5 Q). It all started before the exam when CISCO give big sign of warning that your result will be pending for their so called analysis. They also conduct online survey asguide how long it takes for you to study for the exam and also mode of training which means by self study or worguide experience. I choose worguide experience instead since i’m afraid if I got high score, analysis will reveal it is impossible for candidates to pass the exam by worguide experience only.

I just passed it with a preliminary score of 1000. I spent 1 hour and 15 minutes.

I had the Following:

Simulator:

1. AAA Simulator, with some issues with # and login on the router, however latest config on this is correct, so don’t worry if you are not able to login on the router to verify it, as me..

Simlet:

1. 2 x SDM Simlet

2. HQ – Branch (1 – 5) VPN Tunnel, I don’t thought there were all 5 questions, however the process it the same for all of them…

3. 1x Multi Site VPN SDM

Drag & Drops:

2-3 from P4S

– PPPOE configuration of physical interface

– Hybrid-coaxial architecture, the one with Local headend, cable modem termination system, cable modem sections

– AH-ESP-IKE

Cheers

ISCW passed in the second attempt, CCNP done.

75 Questions 989/1000 (One question wrong)

1 question out of p4s

My GRE tunnel simlet was a little bit else.

one branch office router had wrong AS number 11 instead of 1

one branch office router had missing default route

the HQ router had a non correct tunnel source to one branch

HQ router had non correct tunnel destination IP for one branch office router configured

one branch office router had non correct mask for the EIGRP subnet configured

can’t remember the orde, but this doesn’t matter.

As somebody already said: Just check all the possible answers with the “show run”, “show ip int brief”, …

Thanks to all for the help!

QUESTION 32:
The Cisco VPN client is being installed on a teleworkers laptop. When configuring
the Cisco VPN Client, what action is required prior to installing Mutual Group
Authentication?
A. The option to “Allow Local LAN Access” must be selected.
B. A group pre-shared secret must be properly configured.
C. A valid root certificate must be installed.
D. Transparent tunneling must be enabled.
Answer: C
Explanation:
The Cisco virtual private network (VPN) Client for Windows (or VPN Client) is software
that runs on a Microsoft Windows-based PC. The VPN Client on a remote PC,
communicating with a Cisco Easy VPN Server on an enterprise network or with a service
provider, creates a secure connection over the Internet.
Mutual authentication should be used instead of group presharedsecrets, Group
presharedsecrets are vulnerable to man-in-the-middle attacks if the attacker knows the
group presharedsecret.
To use mutual group authentication, you need a root certificate that is compatible with
the central-site VPN installed on your system:

Step 1 Your network administrator can load a root certificate on your system
during installation. When you select the Mutual Group Authentication radio button,
the VPN Client software verifies whether you have a root certificate installed.
Step 2 If you do not have a root certificate installed, the VPN Client prompts you to
install one. Before you continue, you must import a root certificate. When you have
installed a root certificate (if required), follow the steps for group authentication.
Example:
QUESTION 33:
The Cisco VPN client was installed on a Certkiller laptop as shown below:

Based on the diagram shown above, what does the “Allow Local LAN Access”
option enable a Cisco software VPN client to do?
A. It allows local traffic from trusted resources to pass through the VPN connection
B. It allows a user to access the resources on the local LAN when connected through a
secure gateway to a central-site VPN device
C. It allows secured remote clients to access local LAN resources through the VPN
connection
D. It allows remote connections from trusted clients to access local resources
E. None of the above

A certifyme.comremote user is getting Internet access from the local cable provider.
When an individual is connected to the Internet by way of a CATV cable service,
what kind of traffic is considered upstream traffic?

A. Traffic going from the user’s home traveling to the headend.
B. Broadcast traffic, including the cable TV signals.
C. Traffic between the headend and the TV signal.
D. Traffic between the headend and the supplier antenna.
E. Traffic from outside the local cable segment serving the user’s home.
F. All of the above can be considered upstream
Answer: A
Explanation:
In the CATV space, the downstream channels in a cable plant (cable head-end to
subscribers) is a point-to-multipoint channel. This does have very similar characteristics
to transmitting over an Ethernet segment where one transmitter is being listened to by
many receivers. The major difference is that base-band modulation has been replaced by
a more densely modulated RF carrier with very sophisticated adaptive signal processing
and forward error correction (FEC).
In the upstream direction (subscriber cable modems transmitting towards the head-end)
the environment is many transmitters and one receiver. This introduces the need for
precise scheduling of packet transmissions to achieve high utilization and precise power
control so as to not overdrive the receiver or other amplifier electronics in the cable
system. Since the upstream direction is like a single receiver with many antennas, the
channels are much more susceptible to interfering noise products. In the cable industry,
we generally call this ingress noise. As ingress noise is an inherent part of CATV plants,
the observable impact is an unfortunate rise in the average noise floor in the upstream
channel. To overcome this noise jungle, upstream modulation is not as dense as in the
downstream and we have to use more effective FEC as used in the downstream.

QUESTION NO: 5
A new cable modem was shipped to the home of a certifyme.comuser, where it is being
installed for the first time. When a DOCSIS 1.1 compliant cable modem first
initializes, (boots up) what does it do?

A. Establishes IP connectivity (DHCP).
B. Determines the time of day.
C. Requests a DOCSIS configuration file from a TFTP server.
D. Scan for a downstream channel and the establishment of timing synchronization with
the CMTS.
E. None of the above.
Answer: D
Explanation:
According to the DOCSIS (Data-over-Cable Service Interface Specifications) when you
first power up a cable modem it starts scanning (starting at a low frequency) for a cable
signal. When it ‘hears’ a cable modem stream it listens for a broadcast (from the service
provider) which contains information (ie. frequency) needed to talk back with the head
end. It then ‘talks back’ and if it communicates the right authentication information, it is
allowed to proceed.

QUESTION NO: 6
You are building a small network at your home and you intend on connecting your
cable modem to a Cisco router. Which router interface would you connect the
modem to?

A. Synchronous serial
B. Asynchronous serial
C. Ethernet
D. auxiliary
E. BRI
Answer: C
Explanation:
In certain environments where a non Cisco Cable Modem (CM) is used, and the CM is
only capable of bridging, a Cisco router such as the Cisco 806 can be connected to the
Cable Modem via the Ethernet interface. The routing can then be performed by the Cisco
router behind the Cable Modem and the Client PC or Customer Premises Equipment
(CPE) will be connected to the Cisco router. Network Address Translation (NAT) can
then be configured on the Cisco router.
When the Cisco router is connected behind the Cable Modem the first problem that might
be encountered is not obtaining an IP address dynamically on the Cisco router’s Ethernet
interface. Most Internet Service Providers (ISPs) allow only one host or PC behind the
Cable Modem. Some ISPs assign an IP address to the PC based on the host name.
Therefore, if you have a Cisco router behind the Cable Modem, then the host name for
the router configured using the hostname command should be the same host name given
by the ISP.
