Can IP address192.168.0.101 be routed to the internet?
No. That address is an RFC1918 address.
There are sets of IP space reserved for private use. These ranges are 10.0.0.0/8; 172.16.0.0/12 192.168.0.0/24. Any address that fall within these ranges are by convention not routable on the internet.
Each address on the internet has to be unique. There are only 4,294,967,296 possible addresses theoretically possible with IPv4. That sounds like a lot, but with over 1 billion computers worldwide, and another billion expected by 2014, this is likely to be exhausted at some point in the not too distant future.
The solution to this problem is called NAT or Network Address Translation. Basically it allows you to create your own network (not directly on the internet), and then use one (or several) public addresses to communicate with the internet.
Since more then one person can have the same address (for example: 192.168.0.1) the addresses cannot know about each other on the internet, as they would conflict.
These addresses are kept as internal, and most routers (at least properly configured routers) on the internet will not pass such an address to the internet.
How does the hop count limit alleviate RIP problems?
A Google search for the phrase
hop count limit rip problems
returns a link which says the following.
"The hop count limit helps RIP instability by limiting the number of times a message can be sent through the routers, thereby limiting the back and forth updating that may occur if part of a network goes down."
The mobile node communicates with a similar agent on the user's home network, known as home agent, giving the home agent the care-of-addressof the mobile node; the care of address identifies the foreign agent's location.
the owner of the resource.
SANs. (Storage Area Networks.)
What application hardening measure addresses secure communication between client and server?
Implementing Secure Sockets Layer (SSL) on the server.
Answer Explanation: Although all of the options may be appropriate as part of your attempt to harden this Web server, the question focuses on providing a secure communications environment to clients when on the corporate Web site. The Secure Sockets Layer ( SSL) protocol helps to secure the data exchange between clients and the Internet server by encrypting the communication link between them.

What is acknowledged connection-oriented service?
Acknowledged connection-oriented service-the source and destination machines establish a connection before any data are transferred.Each frame sent is numbered and the data link layer guarantees that each frame sent is received.

Do Server options take precedence over scope options if they conflict?
Scope options override server options, so in any conflicts between option settings such as DNS servers, the scope option values take precedence.
