A user sends a print job lo a network printer, and the print job uses double the amount of paper as expected.
Which of the following should the user configure to get the expected result?
- A . Duplex
- B . Collate
- C . Landscape
- D . Transparency
A
Explanation:
The user should configure the print job to use the Duplex option, which will print on both sides of the paper and reduce the amount of paper used.
A field technician has been dispatched to a site with an internet outage. Upon arriving, the technician discovers that the POTS lines are not working as well.
Which of the following technologies is the site MOST likely using?
- A . Fiber
- B . Cable
- C . DSL
- D . Satellite
C
Explanation:
DSL (Digital Subscriber Line) uses POTS (Plain Old Telephone Service) lines to provide high-speed internet access. If the POTS lines are not working, it could cause an internet outage for DSL customers. Fiber and cable internet typically use different types of infrastructure, while satellite internet is not reliant on POTS lines. References: CompTIA A+ Certification Exam: Core 1 – Page 231
A technician was called in to look at a user’s PC. The user reported the PC was very sluggish. The HDD light on the PC was constantly on without blinking. The PC itself was slow receiving input and took a very long time to load the OS. The technician also noticed updates had failed.
Which of the following is MOST likely the cause of these issues?
- A . The hard disk drivers have been corrupted
- B . The HDD cables need reseating.
- C . A RAID disk failed.
- D . The HDD has no free space.
D
Explanation:
If a user’s PC is very sluggish, the HDD light on the PC is constantly on without blinking, the PC itself is slow receiving input, and it takes a very long time to load the OS, the HDD has no free space is most likely the cause of these issues. When the hard disk drive (HDD) has no free space, the computer may become slow and unresponsive. The technician should check the amount of free space on the HDD and delete any unnecessary files to free up space.
Which of the following options provides correct information about 2.4GHz and 5GHz wireless frequencies? (Select TWO)
- A . 2.4GHz has less interference. 5GHz transmits inlower speed.
- B . 2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections.
- C . 2.4GHz has a higher data rate. 5GHz has 23 channels.
- D . 2.4GHz has Il channels. 5GHz has no data interference.
- E . 2.4GHz has a higher coverage area. 5GHz has higher bandwidth.
- F . 2.4GHz has a higher bandwidth. 5GHz has lower transmit power.
B,E
Explanation:
The correct answers are B. 2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections and E. 2.4GHz has a higher coverage area. 5GHz has higher bandwidth. The 2.4GHz frequency has a lower data rate compared to 5GHz, but it can penetrate solid objects more effectively and has a higher coverage area. The 5GHz frequency, on the other hand, provides faster data connections and has higher bandwidth, but it has fewer channels and lower transmit power.
CORRECT TEXT
Which of the following is the PRIMARY security concern with virtual machine escape?
- A . Cross-site scripting
- B . Compromising the hypervisor
- C . Overutilization of resources
- D . Rogue virtual machines installed on the hypervisor
B
Explanation:
The primary security concern with virtual machine escape is compromising the hypervisor, which can allow attackers to gain access to other virtual machines or the host system. Virtual machine escape refers to an attack that allows a guest virtual machine to break out of its isolated environment and access other parts of the system.
A technician is upgrading a faulty motherboard that was ordered by an end user for an old, high-end desktop computer. However, the technician is unable to install the CPU into the socket. Upon closer inspection, the technician notices the pins on the CPU do not line up with the socket.
Which of the following would be the best course of action for the technician to take NEXT?
- A . Try to set as many pins as possible.
- B . Install an adaptor to create a universal socket.
- C . Verify the socket type and manufacturer.
- D . Find a compatible motherboard for the CPU.
C
Explanation:
In this situation, the best course of action for the technician to take NEXT would be
C. Verify the socket type and manufacturer. If the pins on the CPU do not line up with the socket on the motherboard, it is likely that there is a compatibility issue between the two components. The technician should verify that the socket type and manufacturer of the motherboard match those of the CPU to ensure that they are compatible.
Which of the following components houses the MX record?
- A . DNS
- B . VLAN
- C . DHCP
- D . SMTP
A
Explanation:
The MX record is housed in the DNS (Domain Name System) which is responsible for translating domain names into IP addresses and vice versa. The MX record specifies the mail server responsible for accepting email messages on behalf of a domain name and is a resource record in the DNS123.
An organization is looking to upgrade the processing ability for its computers. Most users report that whenever multiple applications are being utilized, the system’s response time slows down drastically. When only one application is open, the response time is acceptable.
Which of the following should be upgraded FIRST?
- A . SSD
- B . CPU
- C . HDD
- D . RAM
D
Explanation:
The component that should be upgraded first is the RAM. When multiple applications are being utilized, the system’s response time slows down drastically. This is because the computer is running out of memory. Upgrading the RAM will allow the computer to store more data in memory, which will improve performance when multiple applications are being used123.
A company needs to support a 10Gbps throughput.
Which of the following is the MINIMUM cable category that could be used?
- A . Cat 5
- B . Cat 5e
- C . Cat 6
- D . Cat 6a
D
Explanation:
The minimum cable category that could be used to support a 10Gbps throughput is Cat 6a. Cat 6a cable is required with 10 Gigabit Ethernet for reliable performance with cable lengths up to 100 metres. However, lower-specification cables can often be successfully used, particularly with the shorter cable lengths required in a typical home123.
A technician needs to install RAM into a rackmount server that will be used as a VM host.
Which of the following would be BEST to install?
- A . SODIMM
- B . VRAM
- C . DDR4
- D . ECC
D
Explanation:
When installing RAM into a server that will be used as a VM host, it is recommended to install ECC (Error-Correcting Code) RAM to help prevent errors that can cause virtual machines to crash.
