  A. Check the product manual for the procedure

  ---

  Explanation

  Incorrect Options:

  Use a pry tool to force the cover open: Forcing the cover can cause physical damage to the device.

  Insert the wireless card into the M.2 slot: This step cannot be performed until the cover is properly removed.

  Try to move the cover by sliding it in all directions: Randomly sliding the cover can cause damage if the correct removal method is not followed.

• Question 484:

  Which of the following network devices would an administrator use to distribute traffic evenly throughout multiple nodes?

  A. Load balancer
  B. Bridge
  C. Proxy server
  D. Switch
  E. Firewall
  A. Load balancer

  ---

  Explanation

  A load balancer is a network device that distributes network or application traffic across multiple servers to ensure that no single server bears too much of the load. Load balancing helps to improve application availability, increase scalability,

  and optimize resource utilization.

  A bridge is used to connect two different networks, often to divide a larger network into smaller segments. A proxy server is used to forward client requests to other servers, and can also be used to cache frequently requested data. A switch is

  used to connect multiple devices within a network and to control the flow of network traffic. A firewall is used to secure a network by controlling incoming and outgoing traffic based on defined security rules.

• Question 485:

  A technician is installing a WAP in the company break room. The new access point should have a rating of higher than 50Mbps and minimal range to avoid interference with other access points. Which of the following 802.11 standards should the technician select?

  A. Ac
  B. B
  C. G
  D. n
  A. Ac

  ---

  Explanation

  Ac stands for 802.11ac, which is a wireless networking standard that operates in the 5 GHz frequency band and offers a maximum data rate of 1.3 Gbps. 802.11ac is also backward compatible with 802.11a, 802.11b, 802.11g, and 802.11n standards. If a technician wants to install a WAP (wireless access point) in the company break room that has a rating of higher than 50 Mbps and minimal range to avoid interference with other access points, they should select the 802.11ac standard.

• Question 486:

  A technician is asked to set up a new laptop for a coworker. Which of the following storage devices and interfaces will provide the best performance? (Select two).

  A. 15,000rpm HDD
  B. M.2 SSD
  C. 10,000rpm HDD
  D. NVMe interface
  E. SATA interface
  F. mSATA interface
  B. M.2 SSD
  D. NVMe interface

  ---

  Explanation

  M.2 SSD and NVMe interface are the best options for storage devices and interfaces that provide the best performance. M.2 SSD is a form factor that allows for faster data transfer and lower power consumption than traditional SATA SSDs.

  NVMe is a protocol that enables direct communication between the SSD and the PCIe bus, bypassing the SATA controller and reducing latency and overhead. Together, they offer the highest speed and efficiency for storage devices.

• Question 487:

  A user's smartphone loses its charge rapidly. The user also notices that the phone feels thicker than it was when it was new. Which of the following is the most likely cause of the issue?

  A. Bad battery
  B. Malware infection
  C. Damaged charge port
  D. Poor connectivity
  A. Bad battery

  ---

  Explanation

  The user's smartphone is losing its charge rapidly and feels thicker than it was when new. Both of these symptoms point towards a bad battery. A bad battery loses its ability to hold a charge, leading to rapid draining. Additionally, a bad battery can physically swell, which explains why the phone feels thicker. Malware infection, damaged charge port, and poor connectivity are unlikely causes for both the rapid draining and the increased thickness.

• Question 488:

  Which of the following is the best way to protect the data of a virtual machine in the event of hardware failure?

  A. Redundant hardware
  B. UPS
  C. Cloud-based backup
  D. RAID
  C. Cloud-based backup

  ---

  Explanation

  The best way to protect the data of a virtual machine in the event of hardware failure is to use a cloud-based backup solution. A cloud-based backup solution is a service that copies and stores the data of a virtual machine to a remote server or storage device over the internet. A cloud-based backup solution can offer several benefits, such as: High availability and reliability: A cloud-based backup solution can ensure that the data of a virtual machine is always accessible and recoverable, even if the hardware that hosts the virtual machine fails or is damaged. A cloud-based backup solution can also provide redundancy and fault tolerance, by replicating the data across multiple locations or regions. Scalability and flexibility: A cloud-based backup solution can adapt to the changing needs and demands of the virtual machine, by allowing the user to adjust the backup frequency, retention period, and storage capacity. A cloud-based backup solution can also support different types of backup, such as full, incremental, or differential, depending on the user's preferences and requirements. Cost-effectiveness and simplicity: A cloud-based backup solution can reduce the cost and complexity of maintaining a backup infrastructure, by eliminating the need to purchase, install, or manage hardware, software, or licenses. A cloud-based backup solution can also automate and streamline the backup process, by providing easy-to-use tools and interfaces, such as web portals, APIs, or scripts. Other options, such as redundant hardware, UPS, or RAID, may improve the performance or resilience of the hardware that hosts the virtual machine, but they do not provide a complete protection for the data of the virtual machine in the event of hardware failure. Redundant hardware is a technique that uses multiple components or devices to perform the same function, so that if one fails, another can take over. UPS (uninterruptible power supply) is a device that provides backup power to a system in case of a power outage or surge. RAID (redundant array of independent disks) is a technology that combines multiple disks into a logical unit, to improve the speed, capacity, or reliability of the storage. However, these options may not prevent data loss or corruption due to other causes, such as human error, malware, or natural disasters. Therefore, a cloud-based backup solution is the best way to protect the data of a virtual machine in the event of hardware failure.

• Question 490:

  Which of the following devices is capable of dynamically distributing an IP address?

  A. Hub
  B. Switch
  C. Injector
  D. Router
  D. Router

  ---

  Explanation

  A router is a device that can dynamically distribute an IP address to the devices connected to its network using a protocol called DHCP (Dynamic Host Configuration Protocol). DHCP allows a router to automatically assign an IP address and other network configuration information to a device when it joins the network, without requiring manual intervention from the administrator. A router can also act as a gateway between different networks, such as a local area network (LAN) and the internet1. A hub is a device that connects multiple devices on a network and forwards data packets between them. However, a hub does not assign IP addresses or perform any routing functions. A hub operates at the physical layer of the OSI model and does not understand IP addresses or other network protocols. A switch is a device that connects multiple devices on a network and forwards data packets between them based on their MAC addresses. A switch can improve the performance and security of a network by reducing collisions and isolating traffic. However, a switch does not assign IP addresses or perform any routing functions. A switch operates at the data link layer of the OSI model and does not understand IP addresses or other network protocols. An injector is a device that provides power to another device over an Ethernet cable, such as a wireless access point or a security camera. This is also known as Power over Ethernet (PoE). An injector does not assign IP addresses or perform any routing functions. An injector operates at the physical layer of the OSI model and does not understand IP addresses or other network protocols.
