• Question 752:

  A technician is setting up storage in a server that only has SAS connectors for storage. The technician wants the server to utilize RAID 10 for increased performance. Which of the following storage types should the technician install?

  A. NVMe M.2
  B. Mechanical
  C. mSATA
  D. Optical
  B. Mechanical

  ---

  Explanation

  SAS stands for Serial Attached SCSI, which is a type of interface that connects storage devices to servers or workstations. SAS supports both mechanical hard disk drives (HDDs) and solid state drives (SSDs), but not other types of storage devices, such as NVMe M.2, mSATA, or optical drives12. RAID stands for Redundant Array of Independent Disks, which is a method of combining multiple storage devices into a logical unit that provides improved performance, reliability, or both. RAID 10 is a combination of RAID 1 (mirroring) and RAID 0 (striping), which means that data is written across two or more striped sets of mirrored drives34. Therefore, the only type of storage device that the technician can install in a server that only has SAS connectors and wants to use RAID 10 is mechanical HDDs. Mechanical HDDs use spinning platters and moving heads to store and access data, and they are usually cheaper and have larger capacities than SSDs, but they are also slower and more prone to failure .

• Question 753:

  A user indicates that a laptop is not performing well. A technician determines the laptop has a conventional HDD and that installing a SSD will improve the laptop's performance. Which of the following lists of steps describes what the technician should do to complete the upgrade with the LEAST amount of downtime?

  A. 1. Remove the HDD and install the SSD in the laptop. 2.Install the operating system and necessary applications on the SSD. 3.Connect the HDD to the laptop using a USB enclosure. 4.Copy over all of the user's data.
  B. 1. Leave the HDD in place. 2.Install the SSD in an empty drive bay. 3.Leave all data intact on the HDD. 4.Confirm the SSD is accessible in the operating system.
  C. 1. Connect the SSD to the laptop using a USB enclosure. 2.Clone the HDD to the SSD using cloning software. 3.Remove the HDD. 4.Install the SSD.
  D. 1. Remove the HDD and install the SSD in the laptop. 2.Install the operating system and necessary applications on the SSD. 3.Install the HDD in a USB enclosure. 4.Provide the external HDD for the user to access the old data.
  C. 1. Connect the SSD to the laptop using a USB enclosure. 2.Clone the HDD to the SSD using cloning software. 3.Remove the HDD. 4.Install the SSD.

  ---

  Explanation

  The best way to complete the upgrade with the least amount of downtime is to clone the HDD to the SSD using cloning software, and then replace the HDD with the SSD. This way, the user does not have to reinstall the operating system and applications, or copy over their data manually. The other options would either take more time or result in data loss or inaccessibility. Verified

• Question 758:

  A technician installed a Cat 5 UTP cable approximately 275ft (84m) from a network switch in an office to a workstation located on a factory floor The technician sees both a flashing green LED and a flashing orange LED on the workstation's NIC. Which of the following should the technician do FIRST?

  A. Check the RJ45 end connectors, the jacks, and the ends of the run of the Cat 5 UTP cable for loose connections, pinched bends, and visible damage.
  B. Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run.
  C. Replace the entire run of Cat 5 UTP cable with Cat 5 STP cable.
  D. Upgrade the entire cable run to multimode fiber.
  A. Check the RJ45 end connectors, the jacks, and the ends of the run of the Cat 5 UTP cable for loose connections, pinched bends, and visible damage.

  ---

  Explanation

  The flashing green LED on the NIC indicates that the NIC is receiving power, and the flashing orange LED indicates that the NIC is attempting to establish a network connection. Since the technician installed a Cat 5 UTP cable for this connection, the issue is most likely related to the cable or the connectors. Therefore, the technician should first check the RJ45 end connectors, the jacks, and the ends of the run of the Cat 5 UTP cable for loose connections, pinched bends, and visible damage.

• Question 759:

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

  A. DKIM
  B. MX
  C. SPF
  D. DMARC
  C. SPF

  ---

  Explanation

  The correct answer is

  C. SPF. SPF stands for Sender Policy Framework, which is a protocol that allows domain owners to specify which IP addresses are authorized to send email on behalf of their domains1. SPF helps prevent email spoofing and phishing by verifying the sender's identity and preventing unauthorized use of their domain name12. When an email is received, the receiving server checks the SPF record of the sender's domain, which is a DNS TXT record that lists the valid IP addresses for that domain12. The server then compares the sender's IP address with the SPF record and determines if it matches or not. If it matches, the email passes the SPF check and is accepted; if it does not match, the email fails the SPF check and is rejected or marked as spam12. DKIM stands for DomainKeys Identified Mail, which is a protocol that allows domain owners to digitally sign their emails using a public-private key pair3. DKIM helps ensure the integrity and authenticity of email messages by verifying that they have not been tampered with or forged during transit3 . MX stands for Mail Exchange, which is a type of DNS record that specifies the mail servers that are responsible for receiving email for a domain. MX records help direct incoming email to the correct destination and prioritize them based on preference values . DMARC stands for Domain-based Message Authentication, Reporting and Conformance, which is a protocol that builds on SPF and DKIM and allows domain owners to define how receivers should handle unauthenticated or suspicious emails from their domains. DMARC helps protect domains from email fraud and abuse by providing feedback and reports on email delivery and authentication status . Therefore, SPF is the only service among the options that checks whether the sender's IP address is associated with the sender's domain name when receiving email.

• Question 760:

  A small office has a wireless network with several access points for roaming laptop use. Users occasionally report that the wireless connection drops or becomes very slow. Users have confirmed that this issue only happens when connected to the office wireless network. Which of the following would MOST likely be the cause?

  A. Hidden SSID
  B. Device interference
  C. Ethernet port flapping
  D. High ISP latency
  B. Device interference

  ---

  Explanation

  Device interference is the most likely cause of the wireless connection dropping or becoming slow. Interference can come from other wireless devices, microwave ovens, or physical barriers like walls and metal objects. Hidden SSID, Ethernet port flapping, and high ISP latency are not likely to cause this issue. Wireless interference from other devices can cause a drop in wireless connection speed and stability. In a small office environment, there may be several wireless devices competing for the same bandwidth, causing the issues described.
