Router Questions
Question 1
Explanation
To determine which scheme has been used to encrypt a specific password, check the digit preceding the encrypted string in the configuration file. If that digit is a 7, the password has been encrypted using the weak algorithm. If the digit is a 5, the password has been hashed using the stronger MD5 algorithm.
For example, in the configuration command:
enable secret 5 $1$iUjJ$cDZ03KKGh7mHfX2RSbDqP.
The enable secret has been hashed with MD5, whereas in the command:
username jdoe password 7 07362E590E1B1C041B1E124C0A2F2E206832752E1A01134D
The password has been encrypted using the weak reversible algorithm.
When we enter the “enable secret” command with a number after that, the IOS can specify that the password has been encrypted so it will not encrypt any more and accept that password.
In new Cisco IOS (v15+), it seems the device does not recognize “enable secret 7” command as encrypted password. We tried on Cisco IOS v15.4 and see this:
When we tried to enter the command “enable secret 7 07362E590E1B1C041B1E124C0A2F2E206832752E1A01134D”, the Cisco IOS automatically change the command to “enable secret 5 $1$dLq2$qgzb4bgdsasX8dx1oHOkD.” (in the running-config file). So if you paste an “enable secret 7 …” command from an old Cisco IOS version, you cannot login any more with your password.
Note: In fact, there is an error with the answer D. As we entered the command in answer D, the router denied the encrypted password because it was not a valid encrypted secret password. That means the router also checked if the password was hashed correctly or not. But it is the best answer in this question.
Question 2
Explanation
Excessive debugs to the console port of a router can cause the router to hang. This is because the router automatically prioritizes console output ahead of other router functions. Hence if the router is processing a large debug output to the console port, it may hang. Hence, if the debug output is excessive use the vty (telnet) ports or the log buffers to obtain your debugs.
Note: By default, logging is enabled on the console port. Hence, the console port always processes debug output even if you are actually using some other port or method (such as Aux, vty or buffer) to capture the output. Hence, Cisco recommends that, under normal operating conditions, you have the no logging console command enabled at all times and use other methods to capture debugs.
To enable logging logging on your virtual terminal connection (telnet), use the “terminal monitor” command under Privileged mode (Router#)
Question 3
Explanation
Per-packet load-balancing means that the router sends one packet for destination1 over the first path, the second packet for (the same) destination1 over the second path, and so on. Per-packet load balancing guarantees equal load across all links. However, there is potential that the packets may arrive out of order at the destination because differential delay may exist within the network -> Answer D is correct.
When searching the routing table, the router looks for the longest match for the destination IP address prefix. This is done at “process level” (known as process switching), which means that the lookup is considered as just another process queued among other CPU processes
Interrupt-level switching means that when a packet arrives, an interrupt is triggered which causes the CPU to postpone other tasks in order to handle that packet.
In general, process switching is faster then interrupt-level switching and can cause out-of-order packets.
Question 4
Explanation
The command “debug condition interface <interface>” command is used to disable debugging messages for all interfaces except the specified interface so in this case the debug output will be shown on Fa0/1 interface only.
Note: If in this question there was another “debug condition interface fa0/0” command configured then the answer should be C (both interfaces will show debugging ouput).
Question 5
Explanation
There are a few simple steps you can follow to ensure your VTY lines are as secure as possible. The easiest way is to enable username / password authentication. Other ways are to include an access-list to prevent unwanted IP addresses from connecting and use SSH to encrypt the traffic connecting to the device.
Question 6
Explanation
An Integrated Services Router(ISR) router can be implemented an Ethernet Switch Module to perform both IP routing and inter-VLAN routing. With this module, an ISR router will contain interface vlan configurations.

stop being pathetic you all. nobody here cares you WANT dupms. working with guys like you (with totally cheated certs) in network departments makes other engineers life miserable.
Where do you guys get the dumps for the exam?
Comments should only be for premium members! Site is great but 90% of comments are BS!!
Anybody know where I can study/review ccda 200-310 exam
@RealityMan the only reason you are a so called engineer is because you are on here. You are probably the worst “engineer” ever only concerned about you. If you have nothing good to provide dont visit the site.
please share me the last dump for ccnp 300-101. My email yamil_hazim@ yahoo dot com
Here you GO. Just put “i” at beginning of my name and you will get the download link.
Thank you
Hello Everyone, can you please send me the latest dumps? please thanks in advance mjrosana02@ google dot com thanks thanks
Hello Everyone, can you please send me the latest dumps? please thanks in advance mahmoudkharies95@ (gmail) dot com thanks thanks
Hello everyone,
can somebody send me the latest dumps to my email raspasoti@ (yahoo). I really appreciate it.
How can I look at the actual questions and receive the VCE and dumps?
Do I have to become a member to get those; if not, what advantages do I get by becoming a member?
Does a membership for the CCNP ROUTE also work for the T-SHOOT? I need to take the tests by mid-February. Any help will be greatly appreciated
I would appreciate a copy dumps that someone used recently. monkeyrhino @ hotmail. com.
To all the smart-asses who are telling me not to use the dumps and just study. If Cisco did not word stuff in purposely confusing ways, and didn’t charge 400$(over $500 Canadian) us for an online test, few of us would be doing that. If I fail and lose $500, that is a big hit for me, not sure what you all get paid, but most network guys are not rolling in it. I will take the next month and a half to study my ass off, but I would love a little security.
So if anyone has something recent and not scammy, please communicate it.
@D-Route yes you need premium membership to see the actual questions. I believe you can find the oct dump in the ROUTE FAQs & Tips section which has the same questions. However the dump doesn’t really have explanations for most of the answers. Here not all haver explanations, but most do.
With the premium membership you get access to quizzes as well. You can practice individual sections or mix them like taking a real test.
You also get access to the labs, their explanation and topology.
Overall I would say it’s worth it. It helped me a lot for the SWITCH exam, not so much for ROUTE but I didn’t have the time to go through it all. Is not that much money tbh, a lot cheaper than buying a dump and you get a bit more.
You would need a separate membership for TSHOOT as they are separate pages.
Could someone please send me the most recent dump, please? {email not allowed}
