Part 33. Another bossfight. Hello and Welcome to my Quake IV Walkthrough. I’ve played on medium difficulty and all graphic settings on “high”. Hope you like it. Quake IV is an oldschool Ego-shooter with linear levels, only one way to proceed and lots of guns. I love it;) Developed by: Raven Software/id Software Published: 2005 Publisher: Activison

To help you in your preparation for your Cisco CCNA, CCENT, and CCNP exams, here are some free practice questions covering everything from EIGRP to the OSI model. And for you Network+ and Security+ certification candidates, there are questions for you as well on the OSI model and teardrop attacks. I’ll be adding A+ certification questions in future articles. Let’s get started!

CCNA 640-802 Exam:

By default, what values are considered by EIGRP when computing a path’s metric?

A. bandwidth

B. hop count

C. delay

D. load

E. reliability

F. MTU

Answers: A, C. EIGRP considers bandwidth and delay by default in its route calculations.

Cisco CCENT / CompTIA Network+ Certification:

Which layer of the OSI model is generally recognized as the “management layer”?

Answer: The Session layer.

CompTIA Security+ Certification:

Briefly describe the term “teardrop attack”.

Answer: IP fragments with large payloads are the method of attack. Issues with the TCP fragmentation reassembly code of Windows NT, 96, and 3.1x (among others) created this opening.

CCNP Certification / BSCI Exam:

A non-Cisco router will consider what value first during the BGP best path selection process?

A. AS_PATH

B. origin

C. MED

D. weight

E. LOCAL_PREF

F. aggregator

Answer: E. On a Cisco router, weight is the first consideration. However, weight is a Cisco-proprietary BGP attribute. A non-Cisco router will consider LOCAL_PREF first.

CCNP Certification / BCMSN Exam:

Short answer: How can you change the speed and duplex of multiple ports with one command?

Answer: Use the interface range command to configure multiple ports at one time.

CCNP Certification / ISCW Exam:

Which of the following queueing strategies gives priority to interactive, low-bandwidth communications?

A. FIFO

B. PQ

C. CQ

D. DQ

E. WFQ

Answer: E. That’s what Weighted Fair Queueing (WFQ) does!

I’ll see you soon with more Cisco and CompTIA practice questions!

Whether you are looking to protect a small network in your home or one that is the foundation of your business, you will find that it is first important to understand what kind of threats you might be facing. As soon as you have a computer hooked up in order to connect to the network, you will find that there is a chance that it can be exposed to a number of different risks. When you are thinking about what you can do to make a system a great deal more secure, you will find that an understanding of the risks that you are vulnerable to is something that can help a great deal.

First and perhaps most obviously, is the threat of a virus. While the majority of viruses are simply annoying, there are definitely viruses that can damage your network’s hardware, software, or both. For the most part, a virus is an executable file that will be spread by human means and will require someone to open it before it can do its work on the network. When looking at virus threats, it is worth understanding worms as well, which are considered a subset of viruses. Worms do not need human help to propagate themselves, and in fact one example of the way that they work is to turn your computer into an email server that will distribute copies of themselves.

When looking into network security threats, though, it is very important to consider what risks may be present from inside the system. First and foremost, the idea of bad architecture must be considered. If a network is mis-configured in the first place, it can be a very tempting target for people who are looking to get on it. One obvious example of this would be leaving a wireless network unsecured so that anyone with a network card could get onto it. This can certainly happen in a broader and more disastrous scope.

Interestingly enough, one of the most common measures taken to save time is also one that leaves network systems shockingly vulnerable. Consolidating a lot of services to one machine is a common measure for saving time and resources. It is easy to manage and simple to maintain, but if this single machine is compromised, there is a great deal of harm that can happen. While accidental failure is one thing, there is also the concern regarding the ease with which a single machine could be manipulated. In this case, the answer is frequently redundancy.

Computer network security is something that is very important, and if the information that you are safeguarding has anything to do with money or with personal information, it will achieve even a higher priority. Take some time and think about your system and think about whether it is vulnerable to any of the threats above. The more security that you can provide, the better off you will be. The protection of both your company and your customer depend on this aspect of your company’s working, so always consider what network security means to you.

Network Security is a complex problem that we must deal with every day, especially in big companies. Anytime, hackers can plant vulnerable viruses and Trojans to steal valuable data, and cause data loss and network destruction. There are also internal threats, especially from unsatisfied employees with full access to company data. Company data must be secured from sabotages by industry spies. To achieve the best network security for your company, you can consider using network security software, firewalls, encrypted pages and passwords. By doing these methods, you can at least minimize the risks of being a victim of data theft.

It is not an uncommon case that a company’s computers are hacked by an unsatisfied ex-employee. The simplest way to avoid data theft and malicious damages to the computer is to store all the data on a server instead of an employee’s hard drive. It is really important to eliminate the need of users to keep company’s data on their personal workstation. In most cases, data theft happen to portable computers, so to minimize the risk, it is best if you limit the number of laptop users since laptops can easily be taken home. Don’t think that putting passwords on the stolen laptops can prevent you from losing your company’s data as passwords can be cracked easily.

The Importance of Network Security Solution.

In companies where network is an essential, extra attention must be paid to security to prevent computer virus attacks and data theft. It is not uncommon for hackers to steal identities, financial records and other important company data. To secure your company’s network, you can use encrypted pages, firewalls, and infrastructure protective measures such as software and passwords.

You should also ensure that your password consists of long, non-alphanumerical characters to make it more difficult to be cracked. Also consider to set the expiry time for passwords. It is better if you set a shorter expiry time to keep it more secure.

How To Create Secure Passwords

One of the most important parts of internal network security is a password. To get the best network security, there are several tips for you.

Make sure that passwords include non-alphanumeric characters such as:!,@,#,$,%. Use randomly composed words as your password as hackers will find more difficulties cracking them Avoid using your name, family names, pet names or your birthday because it can be easily cracked Make a longer password because it is harder to *****

A hacker never gives up before finally cracking your password so you must always be aware of their threats. As soon as you have a computer connected to the network, you are exposed to numerous network security risks. The most common security threat that could occur to your computer is a virus attack. There are numerous viruses distributed on the internet and once they get into your network security, they can damage your software, hardware or even both. To prevent such thing from happening to your network, you may consider using network security software or an antivirus. Although the software cannot guarantee that your network will be totally secured, at least you will be able to minimize threats.
