CompTIA Network+ Certification Exam N10-009 Prüfungsfragen mit Lösungen (Q566-Q571):

566. Frage
Which of the following cable types allows the use of QSFP ports without requiring transceivers?

Antwort: D

Begründung:
Twinaxial (Direct Attach Copper / DAC) cables can plug directly into QSFP ports without needing separate optical transceivers. They are cost-effective for short-distance, high-speed connections (commonly in data centers).
A . Multimode fiber requires SFP/QSFP transceivers to convert electrical signals to optical.
C . RG11 is coaxial cable for broadband/cable TV, not used in QSFP ports.
D . Category 6 is twisted-pair Ethernet cabling, not directly compatible with QSFP ports.

567. Frage
Which of the following steps of the troubleshooting methodology comes after testing the theory to determine cause?

Antwort: A

Begründung:
The CompTIA Troubleshooting Methodology states that after testing the theory, the next step is to establish a plan of action to resolve the issue.
Troubleshooting Steps:
Identify the problem.
Establish a theory of probable cause.
Test the theory to determine the cause.
Establish a plan of action and implement the solution. # (Correct step) Verify full system functionality.
Document findings, actions, and outcomes.
Breakdown of Options:
A: Verify full system functionality - Happens after implementing the solution.
B: Document the findings and outcomes - Final step, happens after resolving the issue.
C: Establish a plan of action - # Correct answer. Comes immediately after confirming the cause.
D: Identify the problem - First step, already completed.

568. Frage
Which of the following recovery strategies should a company implement to ensure data center services are quickly restored and accessible after a disaster occurs?

Antwort: B

Begründung:
The correct answer is B. Active-passive approach. CompTIA Network+ N10-009 includes high availability and disaster recovery concepts such as failover, redundancy, and recovery strategies. An active-passive approach uses a primary production system, site, or service that actively handles traffic, while a secondary standby environment remains ready to take over if the primary environment fails. This design helps ensure data center services can be restored and made accessi ble quickly after a disaster because the standby environment is already planned and prepared for failover.
Backup and replication software is important for data protection, but backups alone do not guarantee that services will be quickly available. Restoring systems from backups may require significant time. Cloud computing can support disaster recovery, but it is a broad deployment model rather than a specific recovery strategy. Remote manual failover can restore services, but manual failover usually takes longer and increases the chance of administrative delay or error.
Because the question emphasizes quickly restored and accessible services after a disaster, an active-passive approach is the most appropriate option. It provides a standby recovery environment designed to assume operations when the active data center service becomes unavailable.


569. Frage
Early in the morning, an administrator installs a new DHCP server. In the afternoon, some users report they are experiencing network outages. Which of the following is the most likely issue?

Antwort: B

Begründung:
When a DHCP server is installed and not enough IP addresses are provisioned, users may start experiencing network outages once the available IP addresses are exhausted. DHCP servers assign IP addresses to devices on the network, and if the pool of addresses is too small, new devices or those renewing their lease may fail to obtain an IP address, resulting in network connectivity issues.
Reference: CompTIA Network+ study materials.


570. Frage
A network administrator configured a router interface as 10.0.0.95 255.255.255.240. The administrator discovers that the router is not routing packets to a web server with IP 10.0.0.81/28. Which of the following is the best explanation?

Antwort: C

Begründung:
Understanding Subnetting:
The subnet mask 255.255.255.240 (or /28) indicates that each subnet has 16 IP addresses (14 usable addresses, 1 network address, and 1 broadcast address).
Calculating the Subnet Range:
Subnet Calculation: For the IP address 10.0.0.95 with a /28 subnet mask:
Network address: 10.0.0.80
Usable IP range: 10.0.0.81 to 10.0.0.94
Broadcast address: 10.0.0.95
Router Interface Configuration:
Broadcast Address Issue: The IP address 10.0.0.95 is the broadcast address for the subnet 10.0.0.80/28.
Configuring a router interface with the broadcast address will cause routing issues as it is not a valid host address.
Comparison with Other Options:
The web server is in a different subnet: The web server (10.0.0.81) is within the same subnet range (10.0.0.80
/28).
The IP address space is a class A network: While 10.0.0.0 is a Class A network, this does not explain the routing issue caused by the broadcast address.
The subnet is in a private address space: The private address space designation (RFC 1918) does not impact the routing issue related to the broadcast address configuration.
Resolution:
Reconfigure the router interface with a valid host IP address within the usable range, such as 10.0.0.94.
