Why the all zeros and all ones addresses are usually not assigned as host IP addresses?
These addresses are not assigned to devices because they have a reserved meaning. All zeroes refers to "this network", and all ones usually is assigned to a broadcast address (all devices).
Do you need shielded XLR cable for long distances?
Yes, their purpose is to prevent any unwanted noise in the signal.
An MCSE will get you "in the door" for an interview better than most other certifications. It is also a good indicator that you have expert knowledge on advanced Microsoft technologies and that you are more than just a help desk technician. An MCSE is not a job title and therefor a hard number can not easily be assigned to the value of the certification. Your worth will depend on many factors such as experience, productivity, and communication skills. I would expect an MCSE certification to add between $5000 and $12000 to your yearly earning potential depending on your industry, location, and the ecconomy. If pressed I would say I expect the average MCSE to earn between $55,000 and $68,000.

Deine the topology and explain the advantage and disadantage of bus star and ring topology?
Topology is the structure that describes how devices in a Network are connected.
Bus Topology: Directly connects all devices to network i.e utilises a single Physical medium for Data transmission between devices.
Star Topology: Connects all devices in network through a Central Network connecting device such as Hubs & Switches.
Advantage of Bus Topology is that less connecting cable is used.
Advantage of Star Topology is that Network can function in case one or more devices fail.
Disadvantage of Bus Topology is that whole Network goes down if one device fails.
Disadvantage of Star Topology is that it requires physical connecting medium from Central device to the connecting device i.e more expensive.

math is used in solving crime scenes...for example you use math to find the depth of a wound and find the type of the bullet and if the robber climbed on a ladder to go into your room from the window they measure the prints of the ladder....and alot more

What is this computer's DNS server?
There is no simple to explain answer to this question. DNS server houses the IP addresses used to access internet resources. The internet operates via IP address in the format of 255.255.255.255 (i.e. 192.168.002.015). Since those are hard to remember, DNS servers are responsible for translating the user friendly names like www.intrahost.co.uk to 213.249.135.69. I think there are something like 7 hub DNS servers on the internet that replicate to all the rest (happens constantly). By the way, if you type "CMD" in the Run box on Windows XP, then in the box which appears type "PING www.intrahost.co.uk ". You can see what the IP address is for the website. 213.249.135.69 DNS stands for Distributed Name System. A DNS server resolves a name to an IP address, as stated in earlier, but it can also point to multiple IP addresses for load balancing, or for backup servers if one or more is offline or not accepting connections. Individual organizations may have their own DNS servers for their local Intranet. Some sites have their own DNS server to switch between subdomains within them. For example, a site such as Blogspot can have subdomains come and go quite frequently. Rather than force every DNS server to update their own databases whenever someone creates a new blog, Blogspot could maintain their own DNS server to resolve names within the blogspot.com domain, e.g., to distinguish between myblog.blogspot.com and yourblog.blogspot.com ... their DNS server would be queried once blogspot.com is resolved, and it would be responsible for resolving myblog vs. yourblog. If you don't understand this answer. You could always go for the laymans terns version by asking www.askhorsey.com and see what he says
Primary IP is provided by the service provider to the user. you can see your primary IP on your system by typing My IP on any browser.
What AAA component assigns varying levels of rights to users of network resources?
Authorization - it gives users rights to access specific resources and perform specific tasks.
It's not authentication (username and password - database is stored on servers which use RADIUS or TACACS protocols), nor is it accounting (that tracks which applications are used and the length of time that they are used).
this does appear to be a networking question.
A white oblong pill marked IP 272 is sulfamethoxazole, a generic antibiotic, equivalent to Bactrim.
Why ftp use two ports numbers?
FTP uses separate ports for data and control.
port 20 for data
port 20 for control connection.
Inorder to avoid the extra headers and details for each and every packets which will consume the bandwidth. A separate port is used for data connection.

Can a ccna instructor see what ip you used when taking exams?
I am a CCNA instructor, and I never saw such an option. (Nor did I specifically look for it...) But I suppose that this information might be recorded, and that a higher-level administrator would be able to see this information, as it may be needed to track certain suspicious activity.

What does an unlisted IP address mean?
An IP address that is not on a list. This is in the context of access lists, and there are two primary variants:
Blacklist - block these IP addresses
Whitelist - allow only these IP addresses
Unlisted then means that the IP address is not in the list, which could mean either that it is blocked (if missing from a whitelist) or that it is allowed (if not on a blacklist).
What is the path and file name of the DHCP server configuration file?
DHCP server configuration in /etc/dhcp/dhcpd.conf(FEDORA)
or /etc/dhcpd.conf (RHEL).
What are the transmission mode and transmission media?
There are mainly three types of transmission modes : 1) Simplex : Information can flow only in one direction 2) Half Duplex : Information can flow in both direction but only 1 at a time can send and 1 can receive. 3) Full Duplex : Information can flow in both direction and both can send and rceive at a same time. Transmission media is divided into two : guided (coaxial, twisted pair and fiber optics) and unguided (radio, microwave, infrared).
How do you remotely manage a router on your network?
For a wireless home network, typically there is an IP address needed to access the router.
It is often 192.168.0.1, 192.168.1.1, or 192.168.2.1
Try these in your browser to gain access to manage the router.
What allows an FTP server to keep track of connections from multiple clients to the FTP service?
The packet header source IP address and TCP header source port number
