Jason Dion - CompTIA A+ 1001 Exam Prep #2 Flashcards by Roy Keck

You are configuring a SOHO Network and only denying Specific IP Addresses from accessing the Network while allowing any IP Addresses not found on the List. Which of the following should be implemented?

Allow List
Port Forwarding
MAC Filtering
Blocklist

Blocklist

EXPLANATION:
Blocklist is a Form of Protection where only the items identified specifically on the List are Blocked, whereas all others are allowed. For example, if you create an Access Control List that relies on Blocklisting, it would allow every IP address not found in the Allow List.

Allow List is a form of Protection where only the items identified specifically on the List are allowed, whereas all others are denied. For example, if you create a Access Control list that relies on an Allow List, it would block every IP address that is not found in the Allow List.

MAC Filtering is the application of an Access Control List to a Switch or Access Point so that only clients with approved MAC Addresses connect.

Port Forwarding allows a Router to take requests from the Internet for a particular application and send them to a designated host on the LAN.

Dion Training has asked you to consult on the Installation of their New File Server. The Current Server consists of a RAID5 Array with 3 1TB 7200 RPM Hard Disk Drives. Due to the increased reliance on the new file server, you have been asked to recommend a RAID solution that will help ensure there is NO unscheduled downtime, NO data loss, and increased speed/performance over the current file server. Based on these requirements, which of the following RAID solutions should you recommend?

RAID0
RAID1
RAID10
RAID5

RAID10

EXPLANATION:
RAID10 is the best solution to meet all these requirements since it provides a fully redundant RAID with both the advantages of mirroring and disk striping.

RAID 5 provides redundancy, but it will not improve the speed/performance over the current file server in use since it was also a RAID5. Also provides Block-Level striping with distributed parity to provide redundancy using a minimum of 3 disks.

RAID0 provides disk striping (Speed/Performance) but no mirroring with a minimum of two disks.

RAID1 provides mirroring (Redundancy) but not disk Striping with a minimum of two disks.

Dion Training has decided to use a PaaS solution to host their training courses. The service charges are based on the number of students enrolled in the courses each month. Which type of cloud computing concept is being demonstrated by this pricing strategy?

Metered Service
Resource Pooling
Rapid Elasticity
Synchronization Apps

Metered Service

EXPLANATION:
Resources are measured through a Metering on a per-use basis. The Metering measurement is based on the type of resources such as storage, processing, bandwidth, or active users. The Metering mechanism should be accessible to the customer via a reporting dashboard, providing complete transparency in usage and billing. Metered services are pre-paid, a-la-carte, pay-per use, or committed offerings. A Metered Service like a database may charge its users based on the actual usage of the service resources on an hourly or monthly basis. Example: Dion Training used the AWS Lambda serverless product in some of our automation. This Service charges us $.20 for every million requests processed.

Resource Pooling refers to the concept that allows a virtual environment to allocate memory and processing capacity for a VMs use.

Rapid Elasticity is used to describe scalable provisioning or the capability to provide scalable cloud computing services. Rapid elasticity is very critical to meet the fluctuating demands of cloud users. The downside to Rapid Elasticity implementations is that they can cause significant loading of the system due to the high resource number of allocation and deallocation requests.

Using a Synchronization App can allow the files to be stored on both the laptop and the cloud service while maintaining the latest versions in both places. This allows a user to synchronize content between all of their own devices, as well as share the cloud storage content with other users. Multiple users can simultaneously access the content to work collaboratively, or they can access it at different times. Each users changes are typically marked with a flag or color highlighting to indicate who made changes to what content.

A Client has a workstation with RAID5 configuration and reports that slower than normal performance occurs when reading/writing files to the RAID. You run a diagnostic program against the RAID, and the system passes all of the diagnostic tests without any issues. While you are running the tests, though, you heard clicking noises coming from the RAID. Which of the following is the MOST likely cause of the slow performance being experienced by the Client?

Hard Drive
SSD
RAID Controller
Cooling Fan

Hard Drive

EXPLANATION:
Based on the symptoms described the RAID itself is fully functional, so the RAID controller is not causing any problems. This could be caused by a failing hard drive or the system overheating due to the slow performance. Since there is a clicking noise, this is most likely a hard drive failure since a cooling fan makes a whirring or grinding noise instead. Therefore, we can assume the RAID is made up of magnetic hard drives, and one of those hard disks is starting to fail. To replace the hard drive, you need to find a comparable drive that will work in the array, reboot the computer, and enter the RAID setup program to rebuild the array after replacing that hard drive. If you use a RAID 1, RAID 5, or RAID 10, the system will continue to operate normally, but with slower performance, until you replace the hard drive and rebuild the RAID.

* A Customer recently purchased a touchscreen laptop to use for her schoolwork. It has been working well for about 3 weeks, but today she has brought it into your store for repair because it is not working properly. When she touches an icon on the screen, the program fails to load. You look over the laptop, and the screen appears to be fully intact with no dark blobs or spider web cracks in the panel. You attempt to operate the laptop using the touchscreen, but it appears non-responsive to your touch. You can, however, click on the icons using the laptops touchpad without any issues. Wich of the following components MOST likely needs to be replaced? GPU Inverter Digitizer LCD Panel

Digitizer EXPLANATION: The Digitizer is a touch-sensitive glass panel covering the LCD in a touchscreen assembly. The Digitizer is used to convert touch events to digital signals that can be interpreted as different types of input. The digitizer can be touched and inspected without taking apart the device. A LCD panel is a type of display technology where the image is made up of liquid crystal cells controlled using electrical charges. The LCD Panel is backlight by a cold cathode fluorescent (CCFL) bulb. LCD Panels are used on laptops and have replaced CRT monitors as the main type of computer display screen for desktops as well. The LCD screen is the panel that is inside the device, which displays the image. You cannot get to the LCD without taking the device apart first. When only the touchscreen is broken, you should still see what is happening on the screen, and the screen should still function as normal. When only the LCD is broken, you can still use the touchscreen, but the panel will have dark blobs or spider web cracks or both. When both LCD and touchscreen are damaged, you may still be able to use potions of the touchscreen, and some parts of the LCD may display the image, but you will incur obvious difficulties in using the device as normal. The Inverter (Also know as the Inverter Board, Screen Inverter, or LCD Inverter) is part of the laptop's display assembly. The Inverter is a small green board attached to the base of the LCD panel. In a laptop computer, the LCD screen relies on a backlight source to uniformly light up the screen, and the inverter acts as the power supply for this lighting source. If the inverter is faulty, the display will be too dim to easily see without an external light source like a flashlight. A Graphics Processing Unit (GPU) is a microprocess used on a dedicated Video Adapter Cards or within a CPU with integrated graphics capability to handle the mathematical calculations required to create immersive and 3D graphics.

* You have been asked to setup the email on a Corporate laptop. The employees of Dion Training are only allowed to receive their email on one device. The email should be removed from the Server's mailbox whenever the client connects to the Server to download the message. Which of the following mail protocols should you configure to allow an employee to receive their mail on their laptop and meet these requirements? SMTP IMAP POP3 HTTPS

POP3 EXPLANATION: POP3 is downloaded to the device and removes mail from the Server's mailbox by default. IMAP does not remove the mail from the Server when the client connects but instead maintains a copy on the server indefinitely until the user forces it to be deleted. SMTP is used to send emails, not receive. HTTPS is used for SECURE Web Browsing, not receiving emails.

* What type of cable should be used to connect a laptop directly to another laptop to form an Ethernet network? Patch Cable Serial Cable Crossover Cable Straight-Through Cable

Crossover Cable EXPLANTION: Crossover Cable should be used to connect 2 SIMILAR Devices (PC to PC, Router to Router, Switch to Switch) Straight-through or Patch Cable is a Network Cable that uses the same wiring standard on both ends such as T568A or T568B. Serial Cable is a Data Cable that transmits data a single bit at a time like DB-9.

* Which of the following cloud computing resources are MOST important when determining a cloud file-storage synchronization applications performance? I/O Bandwidth CPU Utilization Disk Speed RAM Utilization

I/O Bandwidth EXPLANATION: I/O Bandwidth is the measurement of the amount of Input and Output operations that can be performed within a given time. The higher the I/O Bandwidth, the faster and more efficient a cloud file-storage synchronization application will become. Applications that rely on large amounts of reading and writing of data require a high amount of I/O Bandwidth. Disk Speed is not nearly as important since most cloud file-storage systems use a Virtualized File System for storage and do not rely on a single disk. Instead, they rely on a Storage Area Network or a Virtualized Storage Solution. The CPU and RAM utilization on the system would not have as large an impact of the Performance as the I/O Bandwidth.

* Ted, a file server admin at Dion Training, has noticed that many sensitive files have been transferred from a corporate workstation to an IP address outside of the local area network. Ted looks up the IP address and determines that it is located in a foreign country. Ted contacts his company's security analyst, verifying that the Workstation's anti-malware solution is up to date and the network's firewall is properly configured. What type of attack most likely occurred to allow the exfiltration of the files form the workstation? MAC Spoofing Zero-Day Impersonation Session Hijacking

Zero-Day EXPLANATION: Since the Firewall is properly configured and the Anti-Malware solution is Up-To-Date, this signifies that a Zero-Day Vulnerability may have been exploited. A Zero-Day Vulnerability is an unknown Vulnerability, so a Patch or a Virus Definition has not been released yet. A Zero-Day Vulnerability refers to a hole in software that is unknown to the vendor. Hackers then exploit this security hole before the Vendor becomes aware and hurries to fix it. This exploit is therefor called a Zero-Day Attack. Zero-Day attacks include infiltrating malware, spyware, or allowing unwanted access to user information. Spoofing is the act of disguising a Communication from an Unknown source as being from a Known, Trusted source. Impersonation is the act of pretending to be someone or something else. Session Hijacking attack compromises the session token by stealing or predicting a valid session token to gain unauthorized access to the Webserver.
