질문 # 465
A customer is adding fiber connectivity between adjacent buildings. A technician terminates the multimode cable to the fiber patch panel. After the technician connects the fiber patch cable, the indicator light does not turn on. Which of the following should a technician try first to troubleshoot this issue?
정답：D
설명：
When working with fiber optic cables, one common issue is that the transmit (TX) and receive (RX) fibers might be reversed. The first step in troubleshooting should be to reverse the fibers at one end to ensure they are correctly aligned (TX to RX and RX to TX). This is a simple and quick step to rule out a common issue before moving on to more complex troubleshooting.

질문 # 467
Which of the following disaster recovery metrics is used to describe the amount of data that is lost since the last backup?
정답：B
설명：
* Definition of RPO:
* Recovery Point Objective (RPO)is a disaster recovery metric that describes the maximum acceptable amount of data loss measured in time. It indicates the point in time to which data must
* be recovered to resume normal operations after a disaster.
* For example, if the RPO is set to 24 hours, then the business could tolerate losing up to 24 hours' worth of data in the event of a disruption.
* Why RPO is Important:
* RPO is critical for determining backup frequency and helps businesses decide how often they need to back up their data. A lower RPO means more frequent backups and less potential data loss.
* Comparison with Other Metrics:
* MTTR (Mean Time to Repair):Refers to the average time required to repair a system or component and return it to normal operation.
* RTO (Recovery Time Objective):The maximum acceptable length of time that a computer, system, network, or application can be down after a failure or disaster occurs.
* MTBF (Mean Time Between Failures):The predicted elapsed time between inherent failures of a system during operation.
* How RPO is Used in Disaster Recovery:
* Organizations establish RPOs to ensure that they can recover data within a timeframe that is acceptable to business operations. This involves creating a backup plan that meets the RPO requirements.
References:
* CompTIA Network+ study materials and certification guides.
질문 # 468
A technician is plugging an Ethernet cable into a switch to bring a new device online, but the device is not showing an active network connection. Previously, another technician turned off unused switchports as part of device hardening. Which of the following describes the port status?
정답：A
설명：
A switchport that was manually turned off during device hardening is administratively down. The port will not provide connectivity until it is re-enabled by an administrator.
질문 # 469
A network engineer troubleshoots an issue with an SMTP relay server. The engineer suspects the issue is related to a reverse DNS lookup failure. Which of the following should the engineer implement to resolve the issue?
정답：B
설명：
The engineer should implement a PTR record. A PTR record is used for reverse DNS lookup, which maps an IP address back to a hostname. This is the opposite of an A record, which maps a hostname to an IPv4 address. Mail systems commonly use reverse DNS lookups as part of anti-spam and mail reputation checks. If an SMTP relay server does not have a valid PTR record, receiving mail servers may reject, delay, or flag messages as suspicious.
The CompTIA Network+ N10-009 objectives include DNS record types, name resolution, email-related records, and troubleshooting network services. PTR records are specifically associated with reverse lookup zones and are the correct record type when the problem involves resolving an IP address to a domain name.
DNSSEC adds cryptographic validation to DNS responses, helping protect against DNS spoofing or tampering, but it does not create reverse DNS mappings. An MX record identifies mail exchangers for a domain, but it does not resolve an IP address back to a name. DoT, or DNS over TLS, encrypts DNS queries.
Therefore, PTR is the correct answer.
