WGU D386 - 4.2 - DB - ch 8 (3 of 4)
Exam-Graded A
1.What is the primary advantage of load balancing?
Enhances performance,
scalability, and reliability
Speeds up system boot time
Reduces internet bandwidth use
Increases data storage capacity
2.How does load balancing contribute to reliability?
By hosting applications on
multiple servers
By increasing data encryption levels
By increasing internet speed
By creating data backups on external devices
3.How do companies cope with high traffic on busy
days like Cyber Monday using load balancing?
By provisioning additional virtual servers
By slowing down internet speeds
By limiting the number of users
By closing down the website
4.What is the purpose of a proxy server?
To make requests for resources
on behalf of a client
To decrease internet speeds
To encrypt data before sending it
over the internet
To physically store data
5.In computer terminology, what is a legacy system?
A system that is old and
outdated by current
standards
, A system that has been passed down
through generations
A system that is highly efficient and modern
A system that is currently under development
6.What is considered as legacy hardware?
Outdated technology
standards and devices
Newly invented devices
The most advanced technology
The latest versions of software
7.Why is it difficult to replace legacy systems?
Because it’s challenging to
find technicians who
understand legacy systems
and the costs are high
Because new systems are less efficient
Because legacy systems have a better design
Because all users prefer legacy systems
8.What is an embedded system?
A system that is critical in a
process and other systems or
processes depend on it
A system that is in a constant state of updating
A system that is old and outdated
A system that is unnecessary for
other processes
9.What is a notable example of a critical legacy system?
SCADA systems
An old gaming console
A personal computer
A handheld device
10. What is a potential security risk with legacy systems?
They may no longer receive
security updates and
patches
They have better encryption standards
They receive frequent security updates
