NEW QUESTION # 246
A user submits an escalated ticket regarding failed logins on their laptop. The user states that the time displayed on the laptop is incorrect. An administrator thinks the issue is related to the NTP. Which of the following should the administrator do next?
  • A. Identify the problem
  • B. Test the theory
  • C. Create a plan of action
  • D. Implement a solution
Answer: A
Explanation:
The first step of troubleshooting is always to identify the problem, which includes verifying the symptoms (incorrect time), asking the user clarifying questions, and checking system logs. Only after confirming the problem can the administrator proceed to form a theory and plan.
A . Plan of action is later.
B . Implement solution comes after testing a theory.
D . Test the theory requires a defined problem first.

NEW QUESTION # 247
Which of the following protocols provides remote access utilizing port 22?
  • A. RDP
  • B. TLS
  • C. SSH
  • D. Telnet
Answer: C
Explanation:
SSH (Secure Shell) is a protocol used to securely connect to a remote server/system over a network. It operates on port 22 and provides encrypted communication, unlike Telnet which operates on port 23 and is not secure. TLS is used for securing HTTP connections (HTTPS) and operates on ports like 443, while RDP (Remote Desktop Protocol) is used for remote desktop connections and operates on port 3389.

NEW QUESTION # 248
A data center interconnect using a VXLAN was recently implemented. A network engineer observes slow performance and fragmentation on the interconnect. Which of the following technologies will resolve the issue?
  • A. Spanning tree
  • B. 802.1Q tagging
  • C. Link aggregation
  • D. Jumbo frames
Answer: D
Explanation:
VXLAN (Virtual Extensible LAN) encapsulates Ethernet frames inside UDP packets, increasing packet size. This can lead to fragmentation and performance degradation unless Jumbo Frames are enabled.
Breakdown of Options:
A . 802.1Q tagging - VLAN tagging enables segmentation but does not address fragmentation issues.
B . Spanning tree - STP prevents loops but does not improve performance for VXLAN traffic.
C . Link aggregation - LACP combines links for higher bandwidth but does not prevent fragmentation.
D . Jumbo frames - Correct answer. Enabling Jumbo Frames allows larger packet sizes, reducing fragmentation and improving VXLAN performance.

NEW QUESTION # 249
Which of the following steps of the troubleshooting methodology would most likely involve comparing current throughput tests to a baseline?
  • A. Document findings
  • B. Test the theory
  • C. Verify full system functionality
  • D. Implement the solution
Answer: C
Explanation:
Verifying full system functionality occurs after implementing a fix. This step ensures the solution resolved the issue and that performance is back to expected levels. Comparing current throughput to baseline measurements is part of validation testing to confirm everything is within normal operational parameters.
A). Implement the solution applies the fix but does not confirm results.
C). Document findings happens at the end of troubleshooting.
D). Test the theory comes earlier, when trying to confirm the suspected cause.
