Routers R1 and R2 are directly connected via their serial interfaces and are both running the EIGRP routing protocol. R1 and R2 can ping the directly connected serial interface of their neighbor, but they cannot form an EIGRP neighbor adjacency. What action should be taken to solve this problem? Configure both routers with the same EIGRP process
A distinct physical circuit dedicated to directly connecting devices, such as multiplexers, PBXs, and host computers. A dedicated circuit, also known as a leased line, can be provisioned over a private network comprising facilities owned by the end user organization, although it more typically is in the form of a leased line provisioned over a public network. What layer of the TCP/IP model do routers belong in? NETWORK LAYER 3 What is the point called where the Smart Jack on the Customer side interfaces with the Smart Jack on the Telco side? DEMARC What is SONET WAN technology?
c. 66.154.11100000.96 Is not allowed mixture of binary notation and dotted-decimal notation d. 215.54.66.43 Yes we can e. 220.196.082.46 There must be no leading zero (045). 6. Find the number of addresses in a range if the first address is 192.168.59.0 and the last address is 192.168.85.70. (4 points) 0.0.26.70 = 70*256^0+26*256^1=6727 The range is 6727 7. List the IPv4 addresses that cannot be assigned for public use?
* PPP- from one point to another, rather than broadcast. A control protocol is a protocol that runs atop the Point-to-Point Protocol (PPP) and that is used
2. In a pure ULT strategy, a multithreaded application cannot take advantage of multiprocessing. A kernel assigns one process to only one processor at a time. Therefore, only a single thread within a process can execute at a time. In effect, we have application-level multiprogramming within a single process.
/public C. /migrate D. /span Answer: B When using Mstsc.exe, the /public option establishes a connection to the specified terminal server in a mode suitable for use on a computer in a public place that does not cache passwords or bitmaps. 23. For Internet clients to connect to a TS Gateway server using SSL, the server must have issued a __________ by a source that the client computers
Back in the late 1970's, two projects began independently with the same goal in mind, which was to define a unifying standard for the architecture of networking. One was the ISO, (International Organization for Standardization), the other was the CCITT, (International Telegraph and Telephone Consultative Committee), both of these organizations developed a document that defined similar network models. It was deployed widely as an instructional tool, the OSI Reference Model was intended to serve as the foundation for the establishment of a widely-adopted suite of protocols that would be used by international networks, which became the internet, called the OSI Protocol Suite. 3. What is the history of the TCP/IP model?
IP Address Class A, Class B, and Class C IP Address classes were the original organizational structure for IP addresses. The specific address class would determine the maximum potential size for a computer network. The address class would define which of the specific bits of the address would be used to identify the network and network identification, the bits to identify the host computer and host ID, and total number of host subnets permitted per network. Five total classes of IP addresses were defined, class A through E. Although the IP class term will commonly be used to describe the difference between one network and another, the practical use of addressing is not commonly used any more. It has been replaced with classless addressing where a netmask can be assigned to any IP address range.
Explain. Yes, The class which implements an interface provides method implementations for each of the abstract methods defined in the interface. 5.5 Create an interface called Visible that includes two methods: makeVisible and makeInvisible. Both methods should take no parameters and should return a boolean result. Describe how a class might implement this interface.
What are well known ports? i. Also known as “reserve ports”, which are ports 1 – 1023 that are reserved by ICANN (Internet Corporation for Assigned Names and Numbers). Port Number Assignments Port Numbers Description 1 - 1023 The “well known” ports 1024 – 49,151 Registered ports 49,152 – 65,535 Private Ports 4.
