There are five phases in the SDLC. The characteristics of each of these phases are enumerated below:
* Phase 1: Phase i of the SDLC is known as initiation. In this phase, the need for an IT system is expressed and the purpose and scope of the IT system is documented.
* Phase 2: Phase 2 of the SDLC is known as development or acquisition. In this phase, the IT system is designed, purchased, and programmed.
* Phase 3: Phase 3 of the SDLC is known as implementation. This phase involves the system security features. The system security features should be configured, enabled, tested, and verified.
* Phase 4: Phase 4 of the SDLC is known as operation or maintenance. This phase describes that the system should be modified on a regular basis through the addition of hardware and software.
* Phase 5: Phase 5 of the SDLC is known as disposal. This phase involves disposition of information, hardware, and software.

Explanation: Answer option B is correct.
Quality of Service (QoS) is a technology for prioritizing traffic on the network. VoIP requires optimization of bandwidth to ensure users do not experience "call drops" created by lack of bandwidth due to congestion issues. QoS is a mechanism to provide this optimization.

Certificate-based authentication is the most secure authentication scheme. A certificate- based authentication scheme is a scheme that uses a public key cryptography and digital certificate to authenticate a user. A digital certificate is an electronic document that includes identification information, public key, and the digital signature of a certification authority based on that certification authority's private key. When a user connects to the server, he presents his digital certificate containing the public key and the signature of the certification authority. The server verifies the validity of the signature and whether the certificate has been provided by a trusted certificate authority or not. The server then authenticates the user by using public key cryptography to prove that the user truly holds the private key associated with the certificate.
Answer option B is incorrect. Basic authentication is a simple method of authentication that provides minimum security. It should be used only when security is not critical because basic authentication requests are not encrypted.
Answer option A is incorrect. Form-based authentication Form-based authentication allows users to create their own custom forms. It requires session tracking for the authentication, so that the container may use the login form. It is not a secure authentication scheme.
Answer option C is incorrect. Digest authentication is a secure authentication method in which passwords are sent across a network as a hash value rather than as clear text. It is a more secure authentication method as compared to Basic authentication. Digest authentication works across proxy servers and firewalls.

Business Partner Agreement (BPA) contains the complete terms and conditions which both the partners agree to be bound by as a participant in the partner program. This program comes into action once the application to participate in the Program is accepted by both the partners.
Answer option B is incorrect. Document automation is the design of systems and workflow that assist in the creation of electronic documents.
Answer option D is incorrect. Implicit contract refers to voluntary and self-enforcing long term agreements made between two parties regarding the future exchange of goods or services.
Answer option C is incorrect. An indenture is a legal contract reflecting a debt or purchase obligation, specifically referring to two types of practices: in historical usage, an indentured servant status, and in modern usage, an instrument used for commercial debt or real estate transaction.

A partnership is a for profit business association of two or more persons. Because the business component is defined broadly by state laws and because persons can include individuals, groups of individuals, companies, and corporations, partnerships are highly adaptable in form and vary in complexity.
A partnership is an arrangement where parties agree to cooperate to advance their mutual interests. Partnerships present the involved parties with special challenges that must be navigated unto agreement. Each and every partner shares directly in the organization's profits and shares control of the business operation. The consequence of this profit sharing is that partners are jointly and independently liable for the partnership's debts.
