Answer:
The user is out of the effective range of the wireless access point on her floor.
Explanation:
This user is obviously not close to the access point. As help desk, if a user ever calls to complain about slow speeds or intermittent connectivity while trying to access the network, the first question that you should ask them is how far out are they from the modem or the Access Point. The location between her and the access point might affect the performance of the wireless network. Since she is working from the break room that is two floors above the floor where she normally works, then this means that the walls and ceilings will act as an obstruction to the Wi-Fi signal. The number of Walls and other obstacles will obviously affect the range of the Wi-Fi and will limit the signal’s effectiveness. I will advise the user to go back to her initial working area or be within range to the access point.

You support Richman Investments, a brokerage firm that employs 20 brokers. Each broker has his own client computer, and the firm has a server running Windows Server. All of the client computers are configured identically. Over the past six months, some Windows updates have caused the computers to hang, leaving the brokers without computers to conduct business. How can you ensure that the Windows updates that install on client computers will not cause usability issues?
Answer:
Test Windows update on one computer first.
Explanation:
To ensure that there are no usability issues, the Windows update services should be tested on one computer. This move is to check for any usability issues before the update is deployed to other computers. As soon as the usability is tested and confirmed on one computer after the update, the Windows update services can be used to deploy the updates to other computers.
Two Auto Scaling applications, Application A and Application B, currently run within a shared set of subnets. A Solutions Architect wants to make sure that Application A can make requests to Application B, but Application B should be denied from making requests to Application A. Which is the SIMPLEST solution to achieve this policy
Answer:
Using Network Access Control Lists (ACL) to allow/deny traffic based on application IP addresses
Explanation:
ALL Network Access Control List has has distinct inbound and outbound rules.
Each of these rules are configured to either allow or deny traffic.
This is the best and easiest way to achieve the task at hand.
The Network ACL will be configured to allow inbound and outbound traffic for Application A to send and receive requests and only inbound traffic will be allowed for Application B to receive requests only from A

You have two LANs connected via a router. Network 1 has a DHCP server with a single Ethernet interface. Network 2 does not have a DHCP server. You want the hosts on Network 2 to be able to get IP addresses from the DHCP server on Network 1. What should you configure
Answer:
You can connect to the DHCP using manual addressing if there is only one interface for ethernet on Network 1
Explanation:
For a device to connect to the Internet, it requires an IP Address, Subnet Mask, Default Gateway and DNS.
So, to connect to the Internet for Network 2, you need to manually change the IP addressing but leave other settings the same.
Let's say Network 1 is connected to this network
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS: 192.168.1.1
Then, Network 2 has to be manually configured to
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS: 192.168.1.1
Every other thing remains the same except a little change to the IP Address
Answer:
Configure a DHCP relay agent on the network 2 router interface and configure the hosts in the network 2 to receive IP address dynamically.
Explanation:
DHCP is an application layer protocol which is used to assign IP addresses and other configuration parameters dynamically.
DHCP relay agents are devices configured to allow networks with no DHCP server access other networks with DHCP for it's services. Without this relay agent, the host can not access the DHCP server in other networks because the router interface is a broadcast and will not broadcast to other interfaces.
Hosts in the network can only send DHCP request broadcast messages if configured for dynamic IP addressing.

Would you recommend it to others?
Why or why not?
A career in the graphic and web design field which best interests me is multimedia design.
Explanation:
What about it is appealing?
A multimedia designer uses art, sound, and design skills to create videos, audio, and animated images. They produce sketches, plans, scale models, or drawings. Multimedia designers are responsible for designing props, sets, and costumes, directing set assistants on design interpretations, and advising on other areas of technical production such as lighting and sound to ensure the production set closely resembles their designs. The job of the multimedia designer requires imagination and creativity combined with technical expertise in applying a wide range of software applications.What would be the hardest part of the career?
When creating something for others (especially those that are very vague about what they want or have no clue what they'd like you to create) it's a whole different story. To create something for another person requires you to get into their head.To create something that they'd want and I'm not great at that. And then there's that whole business about people commenting your artwork, or the thing that you created for themWhat would be the hardest part of the career? Why or why not?
Yes, I would recommend it to others. Multimedia designers are the creative minds behind advertisements, informational videos, and many other types of content you come across online or while watching television. They combine text, audio, animation, photography, and video to create informational and impactful content.Write a statement that declares a PrintWriter reference variable named output and initializes it to a reference to a newly created PrintWriter object associated with a file named "output.txt".
Answer:
PrintWriter variable = new PrintWriter("output.txt");
Explanation:
There are two ways of declaring a reference variable in programming.
One way is
Reference Variable-name = new Reference ("some texts here");
While the other is
Reference Variable-name;
Variable-name = new Reference ("some texts here");
Both ways are valid ways of reference variable declaration.
In the question above, the reference is PrintWriter, it points to output.txt and the question says "write a single statement";
Hence, we make use of
PrintWriter variable = new PrintWriter("output.txt");
A reference variable is declared to be of a specific type and that type can never be changed.
Which installation changes from the old information system to the new one incrementally, starting with one or a few functional components and then gradually extends the installation to cover the whole new system?
Answer:
Phased installation
Explanation:
The name of this strategy is phased installation. Phased installation (or phased implementation) occurs when an existing system is replaced by a new one. However, unlike most implementations, this takes place in stages. This has several advantages. First, it allows you to test the system. If there is a problem with it, it is easier to revert back to the old strategy. Moreover, if employees need to adopt this new system, it allows them to get used to it slowly while still being able to access the previous one.
Final answer:
Incremental implementation is a method that replaces an old information system with a new one in a gradual manner, beginning with a few components and then extending to the entire system, which is part of the incremental design process.
Explanation:
The installation method where the old information system is replaced by the new one incrementally, starting with one or a few functional components and then gradually extending the installation to encompass the entire new system, is known as incremental implementation. This approach allows for portions of the system to be updated and enhanced piece by piece, providing a controlled transition from old to new systems and minimizing disruptions. It's a part of the overall incremental design process, where design is done in pieces, and each piece can be modified or enhanced as needed to gradually improve the entire system. Throughout the project, as design efforts increase, the necessary infrastructure, including supply chains for components and manufacturing facilities, must be established to support the production and distribution of the newly designed product or system.

Answer: d
High development costs.
Explanation: Simulation is an approximate imitation of a process or a system that represents it overtime.
In Computer simulation is said to be a process of mathematical modelling that is performed on a computer and is designed to predict the behaviour of or the outcome of a physical system. Computer simulations are now useful tools for the mathematical modeling of many natural systems like in computational physics, astrophysics, climatology, chemistry, biology and manufacturing and also human systems like in economics, psychology, social science, health care and engineering.
" Simulations can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions and also to do a wide range of other things", but its development cost is very high, Very expensive.
Answer:
D. High development costs
Explanation:
Simulations try to as much as possible imitate the functions or activities of a system or process. They cut across various disciplines such as education, technology, science, management and so on.
One common ground about simulations is that it accrues high development costs. This is due to its closeness to the real-world application. Each block of the real process has to be appropriately simulated to ensure that the same results are obtained.
