NEW QUESTION # 133
Which of the following offers access to business productivity applications for a recurring fee?
Answer: B
Explanation:
Software as a Service (SaaS) provides users access to fully managed applications hosted in the cloud.
CompTIA A+ explains that SaaS is subscription-based and typically billed monthly or annually, which aligns perfectly with the phrase "recurring fee." Business productivity applications-such as Microsoft 365, Google Workspace, Zoom, Slack, and Salesforce-are classic examples of SaaS offerings.
SaaS applications run entirely in the provider's cloud environment, eliminating the need for installation, maintenance, or management by the customer. This makes SaaS ideal for businesses that need reliable, scalable tools without maintaining their own infrastructure.
DaaS (Desktop as a Service) provides virtual desktops.
PaaS (Platform as a Service) offers a development framework for building applications.
IaaS (Infrastructure as a Service) provides virtual servers, storage, and networking-not end-user productivity apps.
Thus, SaaS is the correct and only model that matches the description of subscription-based access to productivity applications.
NEW QUESTION # 134
A technician replaces a motherboard in a desktop computer. Alter reassembling the system and turning it on, the computer tails to start, and no display output is shown. The power supply fan and case fans are working, but there are no beep codes or POST messages. Which of the following should the technician do first to make the computer turn on properly?
Answer: A
Explanation:
If fans spin but there is no POST or display after a motherboard replacement, a common cause is the CPU not receiving power. Verifying the CPU power connector (such as the 4-pin or 8-pin EPS connector) ensures the processor is powered and allows the system to start properly.
NEW QUESTION # 135
A user's laptop is projecting an image upside down when connected to a ceiling-mounted projector. Which of the following should the technician do to best resolve the issue?
Answer: C
Explanation:
Ceiling-mounted projectors are specifically designed to be installed upside down and have a built- in feature to invert the image vertically so that it appears correctly on the screen. Using this setting on the projector itself is the standard and best method to resolve this specific issue, as it is intended for this installation scenario.
NEW QUESTION # 136
A user has two SSDs of the same size in their PC. The user wants to configure both SSDs to have a copy of all data so there will be no data loss if one drive fails. Which of the following is this an example of?
Answer: B
Explanation:
This scenario describes disk mirroring, which is RAID 1. With RAID 1, the same data is written to two drives simultaneously, creating an exact duplicate on each SSD. If one drive fails, the system can continue to operate using the remaining drive with no loss of data, which directly matches the requirement "no data loss if one drive fails." RAID 1 is commonly used when fault tolerance and data redundancy are the priority. A key trade-off is capacity: because the data is duplicated, the usable storage is essentially the size of one of the drives (two 1TB drives in RAID 1 provide about 1TB usable). Performance can vary: read performance may improve slightly in some implementations, but write performance is generally similar to a single drive because data must be written to both drives.
RAID 0 is striping with no redundancy, so a single drive failure causes total data loss. RAID 5 requires at least three drives and uses parity. RAID 10 requires at least four drives and combines mirroring and striping.
Therefore, the correct answer is RAID 1.
NEW QUESTION # 137
Which of the following is the best to use to stream real-time video from a network camera?
Answer: B
Explanation:
UDP (User Datagram Protocol) is the preferred protocol for real-time video streaming, such as feeds from network cameras. UDP prioritizes speed and low latency over guaranteed delivery, making it ideal for time-sensitive applications.
Real-time video streaming can tolerate occasional packet loss, but it cannot tolerate delays caused by retransmissions. UDP does not perform error checking or packet retransmission, which reduces overhead and ensures smooth, continuous playback. This is critical for live video feeds where delayed packets are useless.
