Which of the following is a valid form of attack against ARP? A. Flooding B. Spanning tree attack C. Name server poisoning D. Reverse lookups Solution A. Attacks can attack ARP by flooding the switch and other devices with bogus MAC addresses or by ARP poisoning. Answer B is incorrect because although spanning tree is a valid attack, it is typically used for DoS. Answer C is incorrect because name server poisoning is another type of DNS attack. Answer D is incorrect because a reverse lookup is a term associated with DNS, not ARP..

How do open source projects work? How is it different from closed source projects? Discus the creation of a database. Explain its working. (E.g, what you need to use to create tables and relationship? What you do to modify a database?) Explain what\'s SaaS, PaaS and laaS? Distinguish among these three. Solution 31) In open source project the source code of the project is made available to anyone for free. The code can be studied, modified and even redistributed for any purpose.Many of the open source projects are developed in an open collaberative manner. People volunteer to develop the projects.Where as in closed source projects the source code is not developed by an organization and the source code is not openly available. 32) A database consists of many tables created for a project. In mysql it is created using the command \'create database sample_database;\'. We generally use a RDBMS(Relational Database Management System). The data is stored in RDBMS database objects called tables. You can create a table by specifying the number of rows, names of each row and the type of data that will be stored in each of them. 33) SaaS means software as a service in which a software is provided as a serive. Generally the service is centrally hosted, but this many not always be the case. The consumer is charged on a one time basis or in a subscription model. PaaS stands for platform as a service. The service provides platform as a service for customers to develop, manage and run applications. This is generally referred for cloud computing applications. LaaS stands for logging as a serivce. This represents a architechture used for collection of log files from a specific location or source..

Ferdinand is affected by hemophilia, a recessive x-linked condition. He mates with an unaffected woman with no history of hemophilia in her family. Their first child is a girl with Turner Syndrome (XO sex chromosomes), who is also hemophiliac. You infer that she resulted from the following sperm and egg (answers listed in the order of sperm, egg):normal, normal Solution Answer: Because Ferdinand has hemophilia which is X-linked ressesive disease. Daughters produced by mating of ferdinand and a normal female would be carriers of hemophilia. In this case however, the daughter is having Turners\' syndrome (XO) and is heophilic as well. This implies that the X came from sperm of Ferdinand and the O is beacuse the X chromosome from the female was nondisjunct at meiosis I, as non-disjunction at meiosis II would result in two gaetes being normal, One being trisomic and one being monosomic. whereas nondysjunction at meiosis I would give rise to 50% trisomic and 50% monosomic gametes. Hence raising the possibility of turners\' syndrome after nondysjunction at meiosis I. Therefore answer is: c. Normal and non-dysjunction at meiosis I..

Explain whether you think IFRS and GAAP will be fully converged. What is the current status of convergence projects? Solution There has been a concerted convergence effort between the Generally Accepted Accounting Principles (GAAP) and the International Financial Reporting Standards (IFRS) in order to avoid conflict and confusion, promote simplicity, streamlining, consistency and transparency, and avoid any future financial crises or meltdowns. Despite the research-indicated evidence of a higher accounting quality being experienced by firms that either apply the IFRS standards or have switched to them from the GAAP, the convergence process has not proven to be an easy task, mostly because of the differences in approach between the two accounting bodies. The GAAP is a rules-based methodology, while the IFRS takes a principle-based approach. The rules-based approach is comprised of a complex set of guidelines that establishes criteria for every possible contingency and provides the rules required for specified transactions, thus promoting uniformity. The principle-based methodology lays out the key objectives of good reporting in each subject area and then provides guidance, explaining the objective, and relates it to common examples, thus promoting transparency. If these methodological differences between the two approaches cannot be resolved, they may prolong the process of compiling a true set of international accounting standards and increase the costs required to maintain two sets of books. So from the above discussion it is clear that, IFRS and GAAP will be fully converged, but it will took a time. current status of convergence projects One of the main concerns in the United States business world is how the convergence process and its results will impact the future evolution of the accounting profession. This specific concern, simply stated, is about uniformity over transparency, and it has a serious impact on the standards development process. Could the goals of uniformity and transparency be achieved? Are they incompatible or mutually exclusive? This incompatibility - real or perceived - is grounded in the conflicts existing among the constructs of rules-based and principle-based shareholder and stakeholder primacy theories, which are recognized by the Financial Accounting Standards Board (FASB), the International Accounting Standards Board (IASB) and the European and Asian Accounting Standards Boards, and which have an impact on the standards development methodology. Transparency has a direct impact on the areas of business combinations (Phase I and II), revenue recognition and financial performance of business enterprises reporting. hence they are still in process..

Do patients have health care rights that are not legal or statuatory rights? Explain your answer. Solution Legal Conceptualization: it supplies that a patient has a right to realize potential benefits, risks, and option a of proposed therapy; duty of physician to reveal to the patient a full apprehension of the suggested care before patient assent to it. Statuatory Rights: when a patient is clinically unfit to give assent to a lifesaving emergency therapy. The law implicit assent (exigency in most states abolish need for assent).

Describe the authentication process in the figure below: Solution Authentication begins when a user tries to access information. First, the user must prove his access rights and identity. When logging into a computer, users commonly enter usernames and passwords for authentication purposes. This login combination, which must be assigned to each user, authenticates access. However, this type of authentication can be circumvented by hackers. A better form of authentication, biometrics, depends on the user’s presence and biological makeup (i.e., retina or fingerprints). This technology makes it more difficult for hackers to break into computer systems. The Public Key Infrastructure (PKI) authentication method uses digital certificates to prove a user’s identity. There are other authentication tools, too, such as key cards and USB tokens. One of the greatest authentication threats occurs with email, where authenticity is often difficult to verify. For example, unsecured emails often appear legitimate..

Discuss the history of bureaucratic and administrative management. Solution 1. History of Bureaucratic Management: There was time before 1800 when the organisations operated like a family. Supervisors, workers and employees did not have proper defined work. Every one did everything. During late 1800, Max Weber brought about changes in this system of organisational operation. He believed that having an informal organisation decreases the productivity of the employees as they are not focussed and goal-driven. Max Weber created the idea of bureaucratic management which made the organisation more rigid, authorative and structured. He believed that employees do not follow the organisation but they follow their bosses. He defined supervisors and workers role properly. The workers were supposed to take their immediate bosses orders and cannot operate beyond that capacity. Max Weber\'s theory of bureaucratic management has two important elements. First, it involves structuring an organization into a hierarchy system. Secondly, the organization as well as its employees operate through clearly defined rational-legal decision-making rules. Both the elements help the organisation to achieve its goals. 2. History of Administrative Mangement During 1900, the management expert Jules Henri Fayol, came to the conclusion that management is an activity that is followed by all the human undertakings. Management is needed at school, housework, business, government services, etc. All these human undertakings need five basic administrative functions to operate. They are: i. Planning ii. Organizing iii. Commanding iv. Coordinating v. Controlling Henri Fayol rejected the notion that \"Managers are born and not made.\" Instead he believed that management is a skill that can be developed over the time through proper training and enthusiasm. Managemnt skills can be acquired if its principles are understood. Henri Fayol was of the belief that since management is an all-encompassing activity, the management skills should be taught in schools, colleges and universities..

Describe or explain how SNPs in genes at evolutionary conserved breakpoints can lead to dramatic phenotypic differences between species like chimpanzees and humans even though their genomes are 98% similar? Provide and describe or explain an example of one gene with SNP differences between gorillas and humans that might have resulted changes between humans and apes. Solution SNP ( Single nucleotide polymorphism) is a type of genetic variation among living beings. SNP represents a difference in a single DNA building block i.e, nucleotide. SNP replaces the nucleotide cytosine ( C) With ghe nucleotide thymine (T) in a stetch of DNA. The difference between the two genomes of humans and chimpanzees is actually 4% approximately. This msinly contributes to the phenotypic differences in various species. Humans differbfrom other primates like chimpanzees and apes in cognitive abilities and a significantly larger brain. These correlate with metabolic changes, etc. Example of such genes with SNP differences is 90 TF genes with significant expression levels in humans and chimpanzee brain. Among these KRAB-Zinc finger genes are markedly important. The differentially expressed TFs cluster within robust regulatory network consisting of two distinct but interlinked modules, strongly associated with energy metabolism functions and the others with transcription, vesticular transport and ubiquitination..

Can Variance Inflation factors be used to detect Heteroscedasticity problem in the regression analysis Solution Variance inflation factors (VIF) measure how much the variance of the estimated regression coefficients are inflated as compared to when the predictor variables are not linearly related. Use to describe how much multicollinearity (correlation between predictors) exists in a regression analysis. Multicollinearity is problematic because it can increase the variance of the regression coefficients, making them unstable and difficult to interpret. Use the following guidelines to interpret the VIF:VIFStatus of predictorsVIF = 1Not correlated1 < VIF < 5Moderately correlatedVIF > 5 to 10Highly correlated.

A study undertaken by the Miami-Dade Supervisor of Elections in 2002 revealed that 44% of registered voters are Democrats, 37% are Republicans, and 19% are others. If two registered voters are selected at random, find the following probability: One of them is a Democrat and another one is a Republican. Solution Here we have following probabilties: P(democrats)=0.44 P(republicans)=0.37 P(others)=0.19 Since voters are independent from each other so the probabilityOne of them is a Democrat and another one is a Republican is P(One of them is a Democrat and another one is a Republican)=P(democrats)P(republican)=0.44*0.37=0.1628 hence, the required probability is 0.1628..

Among the developing Ceratopteris gametophytes, what proportion of these do you expect to have Polka-Dot mutation? Among the developing Ceratopteris gametophytes, what proportion of these do you expect to have Polka-Dot mutation? Solution ANS: C-Fern(Ceratopteris): The abbreviated name C- fern comes from Ceratopteris richardii. C-ferns are belongs to a hybrid species that most predominantly found in Cuba and Nicaragua. In this ferns the DNA strain cause short life cycle. During its life cycle DNA strains from one fern to other introduced by cross breading. C-ferns can exhibit both haploid and diploid phases. Polka-Dot mutation: The polka dot characteristic is a mutation that was induced using an EMS mutagen. In this mutation, the chloroplasts of ferns are clumped together and creates polka dot look so it is called as Polka-Dot mutation. Matured polka dot C-ferns is appeared as paler when compared with wild type C-ferns. But the growth and reproduction is same. Wild Type Polka Dot: It is a hypothesis expected that, due to the polka dot traits are believed to be recessive. Crossing between the two mutant forms of polka dot C-fern plants will capable to produce only polka dot offspring. If first produced Polka dot C- ferns spores are subjected to an EMS mutagen. EMS can causes many mutations in C ferns, not only polka dots. Some other mutations are pale, lethal, dwarf, ruffled, and bubbles. The plates were sown and the gametophytes were searched through only to find that not enough polka dot C- ferns had been produced to continue the experiment and acquire accurate results..

Rivest, A. Shamir and L.Adleman . ->This method has been widely used to ensure security and secrecy in electronic communication and particularly where financial transactions are involved. ->The private key pair is used to decrypt messages, and this key will only work if the public key of the same site was used to encrypt the message. That is to say, Site B\'s public key is obtained from a directory, then used by Site A to encrypt a message for them. -> The Public Key Cryptography is to send messages in such a way that only the person who receives them can understand them even if the method of encryption is discovered by \'an enemy\' who intercepts the messages. -> The method depends on the fact that while it is easy to calculate the product of two large prime numbers. example: ->Let two primes be a= 7 and b= 13. Thus, modulus n = ab = 7 x 13 = 91. 12)Steganography is ->Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. ->Steganography takes cryptography a step farther by hiding an encrypted message so that no one suspects it exists. -> The difference between steganography and cryptography is that in cryptography, one can tell that a message has been encrypted, but he cannot decode the message without knowing the proper key. -> In steganography, the message itself may not be difficult to decode, but most people would not detect the presence of the message. example: For example, one could hide a text message within a paragraph of words, so that by isolating every 10thword, the secret message can be detected. 13)Symmetric Key Algorithms: -> symmetric key algorithms are used primarily for the bulk encryption of data or data streams. ->These algorithms are designed to be very fast and have a large number of possible keys. -> it is used for the same cryptographic keys for both encryption ofplaintext and decryption of ciphertext. ->The keys may be identical or there may be a simple transformation to go between the two keys. Types of symmetric-key algorithms: a)Stream ciphers encrypt the digits (typically bytes) of a message one at a time. b)Block ciphers take a number of bits and encrypt them as a single unit, padding the plaintext so that it is a multiple of the block size. Blocks of 64 bits were commonly used. -> Symmetric cryptography was well suited for organizations such as governments, military, and big financial corporations were involved in the classified communication. 14) RSA: ->This cryptosystem is one the initial system. It remains most employed cryptosystem even today. The system was invented by.

35. What would be a strong suggestion of convergent evolution from mapping a trait onto a phylogenetic tree (think of how flight would map onto a phylogenetic tree of all animals)? Solution Convergent evolution means that a single character/trait has evolved independently in different subjects. One example is evolution of flight. While mapping the last common ancestor does not have that trait. As branch points split, a single characteristic is found in all the branch points. And in each branch, the character has evolved differently and independently. This is a strong explanation of convergent evolution. In insects, bats and birds, analogous structures i.e. wings developed. Wings have the same function in all these. It is important to note that their forelimbs are homologous structures; performing different functions. This suggests that limb development started from a common ancestor, but slowly, due to similar environmental conditions, all the limbs later adapted to flight. Such a characteristic is known as \'homoplasy\'. So, the strongest suggestion for convergent evolution from mapping a trait onto a phylogenetic tree would be \'homoplasy\' and \'analogous structures/organs\'..

B)The query language JPQL:It is an individualistic programm object oriented programming language.it is laboriously stimulated by SQL and their queries look like SQL queries syntactically.it is depending on the hybernate query language.their manipulation is across the entity objects preferably than straightly with thw database tanbles. C)The java persistance criteria AP: This criteria was included in API 2.0 version. It is mainly to sense dynamic queries with the erection of object form query interpretation objects. It is for energetic queries hardly. it allows the dynamic queries to construct programmitically providing good integration using the java language instead of string based 4th GL approach. D)Entuty beans: It is a venture of endeavour of java beans.it is a server side constituent.if in the receptacle the entity bean is arranged impacts ,the primary key and any of the near mentioned will continue the impact.The constituents of the entity bean applys the javax.ejb.entitiyBean E) Object/relational mapping metadata:It preserves the dta of the programmer and moreover the database itself.almost DBMS habe a many tables that enumerates the tables in database and columns in every table primary and foreign keys ans also stored procedures JDBC offers the interface databasemetadata,that a driver should apply suchntrhat its methods must retrieve details regarding the driver .the interface offers the tools and a systemized procedure to apprehend the metadata..

Why is the answer E. coli B? Bender\'s Experiments Mutations rll1 and rI12 are known to fall into the rlLA and rllB citrons (genes) respectively. Mutations rll1 and rIL2 are used to infect E. Coli K at high multiplicity of infection (m. o. i.) and the progeny phage collected. These phage are then used to infect strain B at high m. o. i. The resulting phage are diluted and plated on both E. Coli B and E. Coli K. Do you expect more plaques on strain B, on Strain K, an equal amount on both or is it impossible to tell? (circle one) E. coli B E. Coli K Equal on both Can\'t tell Solution E. coli B strain allows both mutant as well as wild type phage’s to grow on it hence more number of plaques is noticed on it, whereas E. coli K allows only wild type recombinant phage’s to grow on it hence it produces lesser number of plaques than compared to E. coli B strain..
