Nairobi water company Interview Questions and Answers
Ques:- What are modularization techniques in ABAP and why are they important
Right Answer:
Modularization techniques in ABAP include:

1. **Subroutines (FORM)** - Reusable blocks of code that can be called multiple times.
2. **Function Modules** - Encapsulated functions that can be called from any program or other function modules.
3. **Methods** - Part of classes in Object-Oriented ABAP, allowing encapsulation and reuse of code.
4. **Includes** - Code segments that can be included in multiple programs to avoid redundancy.

These techniques are important because they promote code reusability, improve maintainability, enhance readability, and facilitate easier debugging.
Ques:- How is memory management handled in AUTOSAR systems
Right Answer:
Memory management in AUTOSAR systems is handled through a combination of static and dynamic memory allocation. The AUTOSAR architecture defines memory areas for different software components, and the Memory Management Module (MEM) is responsible for managing memory allocation, ensuring that memory is allocated and deallocated properly, and preventing memory leaks. Additionally, AUTOSAR provides mechanisms for memory protection and access control to enhance safety and reliability.
Ques:- What is the ARM Compiler and what is it used for
Right Answer:
The ARM Compiler is a software development tool used to compile code for ARM architecture processors. It translates high-level programming languages like C and C++ into machine code that can be executed by ARM-based devices, optimizing performance and efficiency for embedded systems and applications.
Ques:- What is the role of GDE in Ab Initio development
Right Answer:
The GDE (Graphical Development Environment) in Ab Initio development is used for designing, developing, and testing data integration applications. It provides a graphical interface for creating graphs, configuring components, and managing metadata, enabling developers to build ETL processes efficiently.
Ques:- What are the differences between Agile, Waterfall, and DevOps methodologies
Right Answer:
Agile is an iterative approach that focuses on collaboration and flexibility, allowing for changes throughout the development process. Waterfall is a linear and sequential model where each phase must be completed before moving to the next, making it less adaptable to changes. DevOps is a culture and set of practices that combines software development (Dev) and IT operations (Ops) to improve collaboration, automate processes, and shorten the development lifecycle, emphasizing continuous integration and delivery.

Ques:- Coaxial Cable?
Comments
Admin May 17, 2020

Coaxial cable comes in two versions: Thinnet and Thicknet.
Thinnet looks like regular TV cable.* It is about 1/4 inch
in diameter and is very flexible and easy to work with. In
contrast, Thicknet is about 1/2 inch in diameter and not
very flexible. Thicknet is older and not very common
anymore except as a backbone within and between buildings.
Coax transmits at 10 Mbps.. Twisted Pair. Twisted pair
looks like telephone wire and consists of insulated strands
of copper wire twisted together.
There are two versions of twisted pair cable: Shielded
Twisted Pair (STP) and Unshielded Twisted Pair (UTP).
STP is commonly used in Token Ring networks and UTP in
Ethernet networks where it is referred to as "10baseT."
Transmission rates vary between 10-100 Mbps..Fiber-Optic
Cable.
Fiber- optic cable consists of a thin cylinder of glass
surrounded by glass cladding, encased in protective outer
sheath. Fiber-optic cable is very fast (100 Mbps). It can
transmit over long distances (2 km +) but is expensive.

Ques:- What is the Command Used to Convert a StandAlone PC into Domain Controller?
Comments
Admin May 17, 2020

In RUN type:-
dcpromo and follow the instructions

Admin May 17, 2020

dcpromo comand can be used to convert a standlone PC into
Domain controller.
The same command can be used to change the domain
controller into a standlone PC.

Ques:- which is true a)bridge connects dissimiler LAN and protocol insensitive b)router connects dissimiler LAN and protocol insensitive c)gateway connects dissimiler LAN and protocol insensitive d)none of the above
Comments
Admin May 17, 2020

B
this is the core function of a router
Bridge requires that the protocols be the same...
gateway is just a concept not an actual device... :)

Admin May 17, 2020

i am sorry but my previous answer might be wrong... gateways
ARE actual devices
Definition
Gateways:
They relay packets among networks that have different
protocols (e.g. between a LAN and a WAN). They accept a
packet formatted for one protocol and convert it to a packet
formatted for another protocol before forwarding it. They
operate in all seven layers of the OSI model.
So i think the answer is C
Sorry once again
