CompTIA CompTIA Certifications N10-009 Questions & Answers

• Question 241:

  Which of the following is the most likely reason an insurance brokerage would enforce VPN usage?

  A. To encrypt sensitive data in transit

  B. To secure the endpoint

  C. To maintain contractual agreements

  D. To comply with data retentin requirements

  Correct Answer: A

  The most likely reason an insurance brokerage would enforce VPN usage is to encrypt sensitive data in transit. VPNs (Virtual Private Networks) create a secure tunnel between the user's device and the corporate network, ensuring that data

  is encrypted and protected from interception.

  Encryption: VPNs encrypt data, preventing unauthorized access and ensuring data privacy during transmission over public or unsecured networks. Data Protection: Essential for industries handling sensitive information, such as insurance

  brokerages, to protect customer data and comply with regulatory requirements.

  Security: Enhances overall network security by providing secure remote access for employees.

• Question 242:

  A newtwork administrator needs to create an SVI on a Layer 3-capable device to separate voice and data traffic. Which of the following best explains this use case?

  A. A physical interface used for trunking logical ports

  B. A physical interface used for management access

  C. A logical interface used for the routing of VLANs

  D. A logical interface used when the number of physical ports is insufficent.

  Correct Answer: C

  An SVI (Switched Virtual Interface) is a logical interface on a Layer 3-capable switch used to route traffic between VLANs. This is particularly useful in environments where voice and data traffic need to be separated, as each type of traffic can

  be assigned to different VLANs and routed accordingly.

  SVI (Switched Virtual Interface): A virtual interface created on a switch for inter- VLAN routing.

  VLAN Routing: Enables the routing of traffic between VLANs on a Layer 3 switch, allowing for logical separation of different types of traffic, such as voice and data. Use Case: Commonly used in scenarios where efficient and segmented traffic

  management is required, such as in VoIP implementations.

  Network References:

  CompTIA Network+ N10-007 Official Certification Guide: Discusses VLANs, SVIs, and their applications in network segmentation and routing. Cisco Networking Academy: Provides training on VLAN configuration and inter- VLAN routing

  using SVIs.

  Network+ Certification All-in-One uide: Covers network segmentation techniques, including the use of SVIs for VLAN routing.

• Question 243:

  A network technician is examining the configuration on an access port and notices more than one VLAN has been set. Which of the following best describes how the port is configured?

  A. With a voice VLAN

  B. With too many VLANs

  C. With a default VLAN

  D. With a native VLAN

  Correct Answer: A

  It is common for an access port to have both a voice VLAN and a data VLAN. A voice VLAN separates voice traffic from regular data traffic, ensuring better quality and security for voice communications.

• Question 244:

  A network engineer configures a new switch and connects it to an existing switch for expansion and redundancy. Users immediately lose connectivity to the network. The network engineer notes the following spanning tree information from both switches:

  Switch 1

  Port State Cost 1 Forward 2 2 Forward 2

  Switch 2

  Port State Cost 1 Forward 2 2 Forward 2

  Which of the following best describes the issue?

  A. The port cost should not be equal.

  B. The ports should use link aggregation.

  C. A root bridge needs to be identified.

  D. The switch should be configured for RSTP.

  Correct Answer: C

  The issue is that no root bridge has been identified. In STP, a root bridge is necessary to manage redundant paths and avoid loops in the network. Without a root bridge, all switches will assume they can forward traffic, causing a network loop and connectivity problems.

• Question 245:

  HOTSPOT

  You have been tasked with implementing an ACL on the router that will:

  1.

  Permit the most commonly used secure remote access technologies from the management network to all other local network segments.

  2.

  Ensure the user subnet cannot use the most commonly used remote access technologies in the Linux and Windows Server segments.

  3.

  Prohibit any traffic that has not been specifically allowed.

  INSRUCTIONS

  Use the drop-downs to complete the ACL.

  Correct Answer: A

  Network Health:

  WAN 2 appears to have a lower average latency and loss percentage, which would make it the preferred WAN station for VoIP traffic. VoIP traffic requires low latency and packet loss to ensure good voice quality and reliability. WAN 1 seems

  to have higher RAM and processor usage, which could also affect the performance of VoIP traffic.

  Here's the summary of the key metrics for WAN 1 and WAN 2 from the image provided:

  WAN 1:

  uk.co.certification.simulator.questionpool.PList@3fe2b50c

  WAN 2:

  For VoIP traffic, low latency and jitter are particularly important to ensure voice quality. While WAN 1 has higher bandwidth and throughput, it also has higher latency and jitter compared to WAN 2. However, WAN 2 has much lower loss, lower

  latency, and lower jitter, which are more favorable for VoIP traffic that is sensitive to delays and variation in packet arrival times.

  Given this information, WAN 2 would generally be preferred for VoIP traffic due to its lower latency, lower jitter, and significantly lower loss percentage, despite its lower bandwidth compared to WAN 1. The high bandwidth of WAN 1 may be

  more suitable for other types of traffic that are less sensitive to latency and jitter, such as bulk data transfers.

  

  Device Monitoring:

  the device that is experiencing connectivity issues is the APP Server or Router 1, which has a status of Down. This means that the server is not responding to network requests or sending any data. You may want to check the physical

  connection, power supply, and configuration of the APP Server to troubleshoot the problem.
