Question 5

Which printing technology offers the lowest cost per page and uses iron-based powder rather than ink?

🫥 Impact
🫥 Inkjet
🫥 Laser
🫥 Thermal

Answer 5

✅ Laser

🧠 Laser printers use toner, a relatively inexpensive iron-based powder, to print.

Question 6

You are involved with providing input in the design of a new small office facility in a rural setting. The fastest possible Internet connection over long distances is required. What should you recommend?

🫥 Fiber optic
🫥 DSL
🫥 Satellite
🫥 Bluetooth

Answer 6

✅ Fiber optic

🧠 This cable type transmits light instead of electricity using plastic fibers over longer distances than is possible with copper-based cables. Some rural areas may not have the infrastructure in place for fiber-optic connectivity. Generally speaking, fiber provides the most network throughput in the order of gigabits per second (Gbps) or even terabits per second (Tbps), where giga implies billions and tera implies trillions.

Question 7

Erin got a gift of a new inkjet printer, and she wants to make sure her computer has a compatible port to plug it in. When she looks at the back of her printer, she sees a lot of port types. Which ones will most likely work for her printer? (Choose two.)

🫥 DVI
🫥 Parallel
🫥 PS/2
🫥 USB
🫥 VGA

Answer 7

✅ Parallel
✅ USB

🧠 Although every modern printer today connects via USB or Wi-Fi, CompTIA remembers the ancient days that included other ports, such as FireWire, parallel, and serial.

Question 8

Your software development team recommends building a new custom software application as an n-tiered application. Which of the following are benefits that will be realized from this design strategy? (Choose all that apply.)

🫥 Developers can change code in one tier without changing code in other tiers.

🫥 One compromised tier does not mean other tiers are also compromised.

🫥 Each tier can have updates applied independently of other tiers.

🫥 All tiers must be backed up together for enhanced availability.

Answer 8

✅ Developers can change code in one tier without changing code in other tiers.
✅ One compromised tier does not mean other tiers are also compromised.
✅ Each tier can have updates applied independently of other tiers.

🧠 Developers can change code in one tier without changing code in other tiers, One compromised tier does not mean other tiers are also compromised, Each tier can have updates applied independently of other tiers. Because each tier is a separate piece of the overall application, each tier can be managed separately of other tiers.

Question 9

You have been tasked with coming up with a solution to efficiently run the highest density of virtual machine on a single host on-premises. What should you do?

🫥 Run a type 1 hypervisor.
🫥 Run a type 2 hypervisor.
🫥 Host the virtual machines in the cloud.
🫥 Configure an on-premises virtualization cluster.

Answer 9

✅ Run a type 1 hypervisor

🧠 This type of hypervisor does not require an existing operating system; it is the operating system.

Question 10

You are configuring a second disk in your macOS computer. What should you choose?

🫥 HFS
🫥 EXT4
🫥 FAT32
🫥 NTFS

Answer 10

✅ HFS

🧠 This is an Apple file system type that is commonly used with macOS.

Question 11

Which document outlines expected uptime and performance details for cloud services?

🫥 SLA
🫥 DRP
🫥 GPS
🫥 DSL

Answer 11

✅ SLA

🧠 Service level agreements are contracts between cloud customers and providers that specify expected uptime and performance when using a specific cloud service.el Agreements

Question 12

Eve purchased a software program on eBay. The package was shrink-wrapped when it arrived and installed just fine. When she clicked the option to activate the program, however, activation failed. What could cause activation to fail?

🫥 Counterfeit program
🫥 Previously installed program
🫥 Invalid operating system
🫥 Virus attack

Answer 12

✅ Previously installed program

🧠 Previously installed program. Although it’s easy to make digital copies of software, activation requires a genuine, not previously activated copy. This is an example of license theft.

Question 13

Which type of testing ensures that software code changes hasn’t broken unrelated code that worked previously?

🫥 Unit testing
🫥 Regression testing
🫥 Sandbox testing
🫥 Performance testing

Answer 13

✅ Regression testing

🧠 This type of test makes sure unrelated functionality has not been adversely affected by new code changes.

Question 14

Which of the following terms is most closely related to measuring database disk performance?

🫥 Kbps
🫥 Caching
🫥 IOPS
🫥 Scale horizontally

Answer 14

✅ IOPS

🧠 Input/output operations per second is a measurement for disk throughput.

Question 15

You have configured an in-memory database cache to improve database query performance. What type of storage is this?

🫥 Persistent storage
🫥 IOPS storage
🫥 Nonpersistent storage
🫥 Network storage

Answer 15

✅ Nonpersistent storage

🧠 Database cached content is stored in RAM, and RAM is nonpersistent storage; when the caching server is shut down, cache contents are normally lost unless configured otherwise.

Question 16

Your colleague Lain has issued the “drop table” command against a customer table. What does this mean?

🫥 The customer table is not accessible over the network.
🫥 The customer table is accessible over the network.
🫥 The customer table has been exported.
🫥 The customer table has been deleted.

Answer 16

✅ The customer table has been deleted.

🧠 DROP TABLEremoves tables from the database. Only the table owner, the schema owner, and superuser can drop a table. To empty a table of rows without destroying the table, use DELETE or TRUNCATE . DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table.
