After an IT department implements SSL redirection, users report being unable to access a random number generator opened within a web browser. Which of the following should a technician do first to troubleshoot this issue?
- A. Reset the web browser cache.
- B. Check to see whether the website is HTTPS enabled.
- C. Ensure that the computer supports secure socket communication.
- D. Report the affected user accounts to the IT department.
Answer: B
Explanation:
After the implementation of SSL (Secure Sockets Layer) redirection, the inability of users to access certain web-based applications or content, like a random number generator, suggests a compatibility or compliance issue with HTTPS (HyperText Transfer Protocol Secure). The first troubleshooting step should be to verify if the website in question supports HTTPS, as SSL redirection forces connections to use HTTPS for security. If the website only operates over HTTP, it won't be accessible after SSL redirection is implemented, leading to the issues reported by users.
References:
* CompTIA A+ Core 1 (220-1101) Exam Objectives, especially sections pertaining to network security protocols and the configuration of client-side network and security settings.
* Understanding of web protocols and security measures, including the significance of HTTPS in ensuring secure communications over the internet and the impact of enforcing SSL redirection on accessing non-HTTPS compliant websites.
NEW QUESTION # 47
Which of the following network devices is used to separate broadcast domains?
- A. Router
- B. Wireless access point
- C. Hub
- D. Switch
Answer: A
Explanation:
A router (option C) is a network device that is used to separate broadcast domains. A broadcast domain is a logical division of a computer network in which all nodes can reach each other by broadcast at the data link layer. Routers operate at the network layer of the OSI model and use routing tables to determine the best path for forwarding packets between different networks.
By separating broadcast domains, routers can help to reduce network congestion and improve performance.
When a router receives a broadcast packet on one of its interfaces, it does not forward the packet to any other interfaces. This means that only devices within the same broadcast domain as the sender will receive the broadcast packet.
NEW QUESTION # 48
A technician is setting up a video-editing workstation and the operating system is already installed on an internal M.2 drive.
The new workstation must meet the following requirements:
. Be able to edit files at the fastest speed
. Allow for disk failure without any downtime
Have 2TB of usable space
. Ensure the most robust fault tolerance
INSTRUCTIONS
Use the drop-down menus to select the appropriate RAID level, drive types, and drive sizes based on the requirements above. For each drive type that is selected, a corresponding drive size must also be selected.
Answer:
Explanation:
Explanation:
Based on the requirements, the best option for the video-editing workstation is to use RAID 10 with four SATA SSDs of 1TB each. This configuration will meet the following requirements:
* Be able to edit files at the fastest speed: RAID 10 combines the advantages of RAID 0 and RAID 1, which are striping and mirroring, respectively. Striping can increase the data transfer rate by using multiple disks in parallel, while mirroring can provide redundancy and reliability by duplicating the data on another set of disks. SATA SSDs are also faster than HDDs or SSHDs, as they use flash memory instead of spinning disks, and they can offer lower latency, higher IOPS, and less noise and heat.
* Allow for disk failure without any downtime: RAID 10 can withstand up to two disk failures, as long as they are not in the same mirrored pair. If one disk fails, the data can be read from or written to the other disk in the same pair, without affecting the performance or availability of the array. The failed disk can be replaced and rebuilt without interrupting the operation of the workstation.
* Have 2TB of usable space: RAID 10 uses half of the total disk capacity for mirroring, so the usable space is equal to the size of two disks. By using four SATA SSDs of 1TB each, the total disk capacity is
4TB, and the usable space is 2TB, which meets the requirement.
* Ensure the most robust fault tolerance: RAID 10 offers the highest level of fault tolerance among the standard RAID levels, as it can survive multiple disk failures and provide fast recovery. RAID 10 also has a low overhead, as it does not use parity or checksums, which can slow down the write performance or increase the complexity of the array.
Therefore, the technician should select the following options from the drop-down menus:
* RAID level: RAID 10
* Drive type 1: SATA SSD
* Drive size 1: 1TB
* Drive type 2: SATA SSD
* Drive size 2: 1TB
* Drive type 3: SATA SSD
* Drive size 3: 1TB
* Drive type 4: SATA SSD
* Drive size 4: 1TB
* Drive type 5: SATA SSD
* Drive size 5: 1TB

Explanation
Punchdown tools are used to connect wires to keystone jacks, patch panels and other communication hardware. When adding a new line at the demarcation point, a technician would use a punchdown tool to punch the wire into the keystone jack or patch panel, completing the connection.
NEW QUESTION # 50
A user submitted a help desk ticket to report that the Wi-Fi connection drops every time the microwave is used. A technician suspects the issue is related to interference. Which of the following should the technician do to provide the BEST long-term solution for the issue?
- A. Change the Wi-Fi operation channel.
- B. Change the SSID to hidden.
- C. Increase the power output of the AP.
- D. Configure the Wi-Fi AP to 5GHz.
Answer: D
Explanation:
Explanation
The issue is related to interference from the microwave, which operates at 2.4GHz, the same frequency as some Wi-Fi channels. To avoid this interference, the technician should configure the Wi-Fi access point (AP) to use a 5GHz band, which has more channels and less interference from other devices. Changing the Wi-Fi operation channel may not solve the problem if the microwave interferes with multiple channels. Increasing the power output of the AP may not overcome the interference and may cause more interference to other devices. Changing the SSID to hidden does not affect the interference at all, and may make it harder for users to connect to the network.

NEW QUESTION # 52
A technician is unable to connect to a network device via SSH_ Which of the following cables should the technician use as an alternative connection method with a laptop?
- A. Lightning
- B. Parallel
- C. Serial
- D. HDMI
Answer: C
Explanation:
The correct answer is
A) Serial.
A serial cable is a type of cable that can be used to connect a laptop to a network device via a serial port. A serial port is a physical interface that allows data transmission between devices using serial communication, which is a method of sending data one bit at a time over a single wire. Serial ports are often used for console access to network devices, such as routers, switches, firewalls, or servers, when other methods of connection, such as SSH (Secure Shell), are not available or not working.
SSH is a protocol that allows secure and encrypted remote login and command execution over a network. SSH uses public key cryptography to authenticate the client and the server, and to encrypt the data exchanged between them. SSH can be accessed through different ports, depending on the configuration of the server and the client. The default port for SSH is 22, but it can be changed to any other port for security reasons.
HDMI (High-Definition Multimedia Interface) is a type of cable that can be used to transmit audio and video signals between devices, such as laptops, monitors, TVs, or projectors. HDMI cables support high-definition video and audio formats, and can also carry Ethernet and power signals. HDMI cables are not suitable for connecting to network devices via SSH, as they are designed for multimedia purposes.
Parallel cables are a type of cable that can be used to connect devices that use parallel communication, which is a method of sending data multiple bits at a time over multiple wires. Parallel cables are often used for connecting printers or scanners to computers, but they are not commonly used for network devices or SSH connections.
Lightning cables are a type of cable that can be used to connect Apple devices, such as iPhones, iPads, or iPods, to computers or chargers. Lightning cables support data transfer and power delivery, and can also be used with adapters to connect to other types of ports, such as USB or HDMI. Lightning cables are not compatible with network devices or SSH connections, as they are specific to Apple products.
Therefore, the only cable that can be used as an alternative connection method with a laptop when SSH is not working is a serial cable. Serial cables can provide console access to network devices and allow configuration and troubleshooting commands to be executed. For more information about SSH and its alternatives, you can refer to the following web search results: Alternatives to SSH, How To Configure Custom Connection Options for your SSH Client, Understanding the SSH Encryption and Connection Process, How to Use Public Key Authentication with SSH.

NEW QUESTION # 56
Afield technician is responding to a ticket about an animated sign with double images. One image is stationary, and the other image is live. Which of the following is the cause of the issue?
- A. Display burn-in
- B. Bad display cable
- C. Burned out bulbs
- D. Incorrect color settings
Answer: A
Explanation:
Display burn-in occurs when a static image is left on a screen for a long time, causing the pixels to wear out unevenly and retain a ghost image even when new content is displayed. This issue can result in double images, where the "burned-in" stationary image persists alongside new, live content. This problem is more common in older displays or those used for static signage. Replacing the display cable or adjusting color settings would not address the underlying cause of uneven pixel wear, and burned-out bulbs would likely result in a loss of image clarity or brightness, not double images.
References: Display burn-in is a well-documented phenomenon in display technology, particularly affecting screens used for signage with static elements.
NEW QUESTION # 57

- A. Reinstall the drive.
- B. Reset the RAID software
- C. Run a chkdek on the drive.
- D. Replace the bad drive.
Answer: D
Explanation:
The correct answer is B. Replace the bad drive.
A clicking noise coming from a hard drive is a sign of a mechanical failure, which can cause data loss or corruption. Replacing the bad drive as soon as possible is the best way to prevent further damage and restore the RAID array to a healthy state. Reinstalling the drive, resetting the RAID software, or running a chkdek on the drive will not fix the underlying hardware problem and may even worsen the situation. Therefore, option B is the correct answer.
Reference:
CompTIA A+ Core 1 (220-1101) Certification Study Guide, page 131: "Clicking noises indicate that the hard drive is failing mechanically." RAID configuration on Linux - Amazon Elastic Compute Cloud, section "Replace a failed volume in a RAID 0 array": "If one of the volumes in your RAID 0 array fails, you must replace it as soon as possible to avoid data loss."
NEW QUESTION # 58
A network technician needs to provide better wireless connectivity throughout a SOHO location. Which of the following should the technician deploy to best improve connectivity?
- A. Wi-Fi router
- B. POE hub
- C. Access point
- D. Managed switch
Answer: C
Explanation:
Explanation
The correct answer is A. Access point.
An access point is a device that extends the wireless coverage of a network by creating a hotspot that allows wireless devices to connect to the network1. An access point can be connected to a router or a switch via an Ethernet cable or a wireless bridge1. By deploying one or more access points throughout a SOHO location, the technician can provide better wireless connectivity and eliminate dead zones or weak signals2.
A managed switch is a device that allows multiple devices to communicate on a network by forwarding data packets based on their destination addresses3. A managed switch can also provide advanced features such as VLANs, QoS, security, and remote management3. However, a managed switch does not improve wireless connectivity, as it only works with wired devices.
A POE hub is a device that provides power and data over a single Ethernet cable to devices that support Power over Ethernet (PoE) technology, such as IP cameras, VoIP phones, and wireless access points4. A POE hub can simplify the installation and placement of these devices by eliminating the need for separate power adapters or outlets4. However, a POE hub does not improve wireless connectivity by itself, as it still requires an access point or a router to create a wireless network.
A Wi-Fi router is a device that combines the functions of a router and an access point, providing both wired and wireless connectivity to a network and the internet. A Wi-Fi router can be used to create a SOHO network, but it may not be sufficient to cover the entire location with a strong and reliable wireless signal. To improve wireless connectivity, the technician may need to add additional access points or use a mesh Wi-Fi system that consists of multiple routers that work together to create a seamless wireless network.
Therefore, an access point is the best option among the choices to improve wireless connectivity throughout a SOHO location.
