   Which of the following models is an example of metered utilization?

   • AReserved instance
   • BPay-as-you-go
   • CSubscription-based
   • DMultitenant

   Show answer

   Answer: B

   Explanation

   An example of metered utilization is: B. Pay-as-you-go. In a pay-as-you-go model, users are charged based on their actual usage of the service or resource. This often involves paying for the amount of resources consumed over time, such as compute power, storage, or network bandwidth. The charges are typically calculated based on usage metrics, such as the number of hours of compute time, the amount of data stored, or the volume of data transferred.

   Which of the following services checks whether the sender's IP address is associated with the sender’s domain name when receiving email?

   • ADKIM
   • BMX
   • CSPF
   • DDMARC

   Show answer

   Answer: C

   Explanation

   The correct answer is: C. SPF Here's why: SPF (Sender Policy Framework) allows domain owners to specify a list of authorized IP addresses that can send email for their domain. When an email is received, the receiving mail server checks the SPF record of the sender's domain to see if the IP address used is authorized. If it's not, the receiving mail server can reject the email or mark it as spam.

3. Question 343 · 624 in bank

   A user reports the following: 1. When accessing large images, PC performance is degraded. 2. When accessing small text files, PC performance is as expected. Which of the following is the most likely cause of the performance issues?

   • AHDD fragmentation
   • BRAID controller failure
   • CRAID array configuration errors
   • DInsufficient power supply

   Show answer

   Answer: A

   Explanation

   A. HDD fragmentation The most likely cause of performance degradation when accessing large images but not when accessing small text files is HDD (Hard Disk Drive) fragmentation. Fragmentation occurs when files are stored in non-contiguous blocks on a disk, leading to increased seek times and reduced performance, especially for large files. The other options (B, C, and D) are less likely to be the cause of the described performance issues. RAID controller failure, RAID array configuration errors, and insufficient power supply are more likely to cause broader system issues or affect all types of file access, not just specific file types or sizes.

7. Question 347 · 624 in bank

   A technician is installing a storage solution for a computer that requires data redundancy with the fewest drives possible. Which of the following would best meet this requirement?

   • ARAID 0
   • BRAID 1
   • CRAID 5
   • DRAID 10

   Show answer

   Answer: B

   Explanation

   For a storage solution that requires data redundancy with the fewest drives possible, the best option would be: B. RAID 1 Explanation: RAID 1, also known as mirroring, provides data redundancy by duplicating the data across two drives. This means that if one drive fails, the data is still available on the mirrored drive, ensuring high reliability. RAID 0 (Option A) provides striping without redundancy, and RAID 5 (Option C) and RAID 10 (Option D) offer both striping and redundancy but require more drives than RAID 1. RAID 10 (RAID 1+0) combines mirroring and striping and requires a minimum of four drives. RAID 5 requires a minimum of three drives, and RAID 0 doesn't provide redundancy.

8. Question 348 · 624 in bank

   Which of the following ports allows for secure communications?

   • A20
   • B22
   • C23
   • D25

   Show answer

   Answer: B

   Explanation

   B. 22 Port 22 is commonly associated with the SSH (Secure Shell) protocol, which provides secure communications over a network. SSH is widely used for secure remote administration of systems and secure file transfers. Therefore, if you want to establish secure communications, port 22 is the relevant one among the options provided. The other ports mentioned (20, 23, 25) are associated with different protocols: Port 20 is commonly used for FTP (File Transfer Protocol) data transfer. Port 23 is associated with Telnet, a less secure protocol for remote access. Port 25 is used for SMTP (Simple Mail Transfer Protocol) for email communication but is not inherently secure.
