CompTIA Network+ Certification Exam Sample Questions (Q53-Q58):

NEW QUESTION # 53
Newly crimped 26ft (8m) STP Cat 6 patch cables were recently installed in one room to replace cables that were damaged by a vacuum cleaner. Now, users in that room are unable to connect to the network. A network technician tests the existing cables first. The 177ft (54m) cable that runs from the core switch to the access switch on the floor is working, as is the 115ft (35m) cable run from the access switch to the wall jack in the office. Which of the following is the most likely reason the users cannot connect to the network?

  • A. An incorrect pinout on the patch cable is being used.
  • B. Mixed UTP and STP cables are being used.
  • C. The cable distance is exceeded.
  • D. The patch cables are not plenum rated.

Answer: A

Explanation:
An incorrect pinout on the patch cable could prevent network connectivity due to mismatched wiring. Even if the cables are the correct length and type, a pinout issue can cause continuity problems and prevent data transmission. Proper crimping with the correct pinout is essential for network cables to function.


NEW QUESTION # 54
An organization requires the ability to send encrypted email messages to a partner from an email server that is hosted on premises. The organization prefers to use the standard default ports when creating firewall rules.
Which of the following ports should be open to satisfy the requirements?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: C

Explanation:
Port 587 is the standard default port for sending email (SMTP) with TLS encryption, which is used to secure email transmissions between mail servers or between clients and mail servers. Allowing traffic over port 587 enables secure email sending while maintaining standard protocol usage. (Reference: CompTIA Network+ Study Guide, Chapter on Ports and Protocols)


NEW QUESTION # 55
A network consultant needs to decide between running an ethernet uplink or using the built-in 5GHz-to-point functionality on a WAP. Which of the following documents provides the best information to assist the consultant with this decision?

  • A. Physical diagram
  • B. Service-level agreement
  • C. Logical diagram
  • D. Site survey results

NEW QUESTION # 56
A company upgrades its network and PCs to gigabit speeds. After the upgrade, users are not getting the expected performance. Technicians discover that the speeds of the endpoint NICs are inconsistent. Which of the following should be checked first to troubleshoot the issue?

  • A. Flow control settings
  • B. Speed mismatches
  • C. Load balancer settings
  • D. Infrastructure cabling grade

Answer: B

Explanation:
Speed Mismatches: If NICs are set to different speeds (e.g., 100 Mbps on one side and 1 Gbps on the other), performance will degrade. Ensuring consistent speed settings between devices is crucial for optimal performance.
Load balancer settings (B): Applies to server load distribution, not endpoint speed.
Flow control settings (C): Can affect performance but is secondary to speed mismatches.
Infrastructure cabling grade (D): Relevant if the cables are unsuitable for gigabit speeds, but speed settings should be checked first.


NEW QUESTION # 57
Which of the following most likely requires the use of subinterfaces?

  • A. A switch using Spanning Tree Protocol
  • B. A router with only one available LAN port
  • C. A hub utilizing jumbo frames
  • D. A firewall performing deep packet inspection

Answer: B

Explanation:
Introduction to Subinterfaces:
Subinterfaces are logical interfaces created on a single physical interface. They are used to enable a router to support multiple networks on a single physical interface.
Use Case for Subinterfaces:
Subinterfaces are commonly used in scenarios where VLANs are implemented. A router with a single physical LAN port can be configured with multiple subinterfaces, each associated with a different VLAN.
