NEW QUESTION # 312
After a data breach, an affected file server is reimaged and must have the data restored. The server array is configured as RAID 6. The technician restoring the data notices that the data transfer is sluggish and restarts the server. After restarting the server, the technician continues the restore process and sees one red LED in the drive array. Which of the following should the technician do next to remediate the issue?
Answer: A
Explanation:
RAID 6 is a redundant array of independent disks that can tolerate up to two drive failures while still maintaining data integrity. According to CompTIA A+ Core 1 (220-1201) objectives, a red LED on a drive in a RAID array indicates that the drive has failed or is in a critical state.
Next Step: In RAID 6, a single failed drive should be replaced immediately to prevent additional failures and maintain redundancy. The array can continue to operate in a degraded state, but performance may be slow during rebuilds. Replacing the failed drive allows the RAID controller to rebuild data onto the new drive, restoring full redundancy.
NEW QUESTION # 313
Which of the following should a technician use in DNS to map a device to an IPv6 address?
Answer: B
Explanation:
The correct DNS record used to map a device to an IPv6 address is the AAAA record. According to CompTIA Core 1 (220-1201) networking fundamentals, DNS uses different record types to associate domain names with specific resources, and each record type serves a distinct purpose.
An AAAA (Quad-A) record maps a fully qualified domain name (FQDN) to an IPv6 address, which is a 128-bit address written in hexadecimal format. As IPv6 adoption increases to address IPv4 exhaustion, CompTIA expects technicians to understand how DNS supports both addressing schemes.
An A record maps a hostname to an IPv4 address only and cannot be used for IPv6. A CNAME record creates an alias that points one domain name to another domain name, not directly to an IP address. An MX record is used for mail server routing and email delivery, not for host address resolution.
CompTIA emphasizes knowing DNS record types and their specific use cases, especially distinguishing between A vs. AAAA records when working with IPv4 and IPv6 networks. When the requirement is explicitly to map a device to an IPv6 address, the AAAA record is the correct and only valid choice.
NEW QUESTION # 314
A user is having issues when charging a device with a Lightning cable. The cable is not recognized when it is plugged into the device. This issue is usually resolved by flipping the cable over. This issue does not occur with other devices of the same type. Which of the following would most likely cause the issue?
Answer: B
Explanation:
When a Lightning cable works only when flipped a certain way or doesn't function consistently, it is typically due to debris or damage in the charging port. Cleaning the port or inspecting it for wear resolves the issue.
NEW QUESTION # 315
A network operations analyst receives an automated alert regarding a server with an array. The analyst walks over to the server and sees a blinking orange light at the hard disk bay. The server is configured for RAID 1. Which of the following should the analyst do to resolve this issue?
Answer: D
Explanation:
A blinking orange light typically indicates a failed hard drive in the RAID array. In RAID 1 (mirroring), you can replace the failed drive and rebuild the array without data loss.
NEW QUESTION # 316
Which of the following devices is used to implement ACL polices for an environment?
Answer: A
Explanation:
A firewall implements ACLs (Access Control Lists) to filter traffic and enforce policies based on rules such as IP address, port, or protocol.
Why Not A (Managed switch): A managed switch supports VLANs and QoS but does not enforce ACLs at the network perimeter.
Why Not B (Gateway): Gateways connect networks and translate protocols but don't typically implement ACLs.
Why Not C (Repeater): Repeaters extend signal range but don't enforce policies.
CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.2, firewall concepts.
