Multiple choice technology architecture

Which among below is an important architectural characteristic that describes the ability of one application to be able to communicate with another application on a different application platform ?

  1. serviceability

  2. portability

  3. extensibility

  4. scalability

  5. interoperability
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Interoperability is the ability of different applications or systems to exchange information and work together, even when running on different platforms or built by different vendors. Serviceability (A) is ease of maintenance. Portability (B) is running on different platforms. Extensibility (C) is adding features. Scalability (D) is handling growth.

Multiple choice technology architecture

Which of the following characteristic describes the ability to migrate an application to execute on other application platforms?

  1. portability

  2. extensibility

  3. interoperability

  4. availability

  5. serviceability
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Portability is the characteristic describing how easily an application can be moved from one platform to another (e.g., Windows to Linux, one cloud provider to another). Extensibility is adding functionality. Interoperability is communication between systems. Availability is uptime. Serviceability is ease of maintenance.

Multiple choice technology architecture

Most EJB servers show high degree of availability. Server clusters are an example of how this is functionality is achieved. What key advantages might server clusters offer in an EJB environment?

  1. Load distribution, Load balancing capability

  2. Location transparency

  3. Caching capability

  4. 2PC (Two phase commit) capability
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Server clusters provide high availability and scalability in EJB environments by distributing incoming requests across multiple servers. This load distribution prevents any single server from becoming a bottleneck and allows the system to continue functioning even if one server fails. The load balancing capability ensures optimal resource utilization and improved performance. Location transparency, caching, and 2PC are separate concepts not directly related to clustering benefits.

Multiple choice technology platforms and products

When deploying TIBCO applications to a failover cluster under one or multiple cluster groups, which two must be owned by the cluster group that hosts the TIBCO products? (Choose 2)

  1. hostname

  2. IP address

  3. shared cache array

  4. shared disk resource
Reveal answer Fill a bubble to check yourself
B,D Correct answer
Explanation

In a failover cluster, the IP address and shared disk resource must be owned by the cluster group hosting the TIBCO products to ensure proper failover functionality. The IP address is needed for network identity, and the shared disk ensures data persistence during failover. Hostname and shared cache array are not cluster-owned resources.

Multiple choice technology architecture

Most EJB servers show high degree of availability. Server clusters are an example of how this is functionality is achieved. What key advantages might server clusters offer in an EJB environment?

  1. Load distribution, Load balancing capability

  2. Location transparency

  3. Caching capability

  4. 2PC (Two phase commit) capability
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

EJB server clusters provide high availability through load distribution and load balancing capabilities. When multiple EJB servers are clustered, incoming requests can be distributed across the cluster, preventing any single server from becoming a bottleneck. If one server fails, requests can be routed to other servers. Location transparency (B) is provided by the EJB container itself, not specifically by clustering. Caching capability (C) is application-specific. Two-phase commit (2PC) is a transaction protocol, not a clustering benefit per se.

What are the support functions that the Container provide ____________?

  1. Communication Support

  2. Life-cycle Management

  3. Multithreading support

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The servlet container provides comprehensive support services including communication mechanisms (request/response handling), lifecycle management (instantiation, initialization, destruction), and multithreading support (managing concurrent requests). These infrastructure services allow developers to focus on business logic rather than runtime concerns.

It supports multiple users working simultaneously on rule development with proper version control and governance.

Multiple choice technology architecture

Which of the following is not a tier of three-tier architecture?

  1. Client Interface.

  2. Business Logic.

  3. Security

  4. Data Storage.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Three-tier architecture consists of: 1) Presentation Tier (Client Interface), 2) Business Logic Tier (application logic), 3) Data Storage Tier (databases/persistence). 'Security' is a cross-cutting concern, not a distinct tier - it applies across all three tiers (authentication at presentation, authorization at business logic, data encryption at storage).

Multiple choice technology architecture

Which of the following is not a good example of a qualitative criteria for consideration in evaluating the Applications Architecture?

  1. transaction volume

  2. availability

  3. application functionality

  4. reliability

  5. security
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Application functionality is a functional requirement, not a qualitative quality criterion. Qualitative criteria assess quality attributes like availability, security, reliability: how well the system performs its function. Transaction volume (A) is quantitative. Availability, reliability, and security (B, D, E) are genuine qualitative quality characteristics describing non-functional aspects.

Multiple choice technology architecture

What is (IdM) Identity Management ?

  1. Identify a User for a resource access

  2. Authorization of User for a resource access

  3. Create Identity and Provision a user for resource access

  4. Auditing user access request for a resource
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Identity Management (IdM) encompasses creating user identities and provisioning access rights to resources. It goes beyond mere identification or authorization to include the full lifecycle of user account management. IdM systems handle user creation, attribute management, and access provisioning across multiple systems.
