CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 911:

  Which of the following is the LARGEST MTU for a standard Ethernet frame?

  A. 1452

  B. 1492

  C. 1500

  D. 2304

  Correct Answer: C

• Question 912:

  A technician is installing a cable modem in a SOHO. Which of the following cable types will the technician MOST likely use to connect a modem to the ISP?

  A. Coaxial

  B. Single-mode fiber

  C. Cat 6e

  D. Multimode fiber

  Correct Answer: A

  Coaxial cables are commonly used in cable television and broadband cable Internet installations. They are typically used to connect the cable modem to the wall outlet or the cable modem termination system (CMTS) provided by the ISP.

• Question 913:

  Which of the following BEST describes a network appliance that warns of unapproved devices that are accessing the network?

  A. Firewall

  B. AP

  C. Proxy server

  D. IDS

  Correct Answer: D

  -

  IDS stands for Intrusion Detection System. It is a type of security software designed to detect unauthorised access to, or attacks on, a computer network. IDS works by monitoring network traffic and looking for signs of malicious activity, such as suspicious network packets, unusual traffic patterns, or attempts to exploit vulnerabilities in the network or in specific systems.

  -

  The goal of IDS is to provide early warning of potential security threats and to help prevent attacks before they can cause damage.

• Question 914:

  Which of the following is the physical topology for an Ethernet LAN?

  A. Bus

  B. Ring

  C. Mesh

  D. Star

  Correct Answer: D

• Question 915:

  A network technician is reviewing the interface counters on a router interface. The technician is attempting to confirm a cable issue. Given the following information:

  

  Which of the following metrics confirms there is a cabling issue?

  A. Last cleared

  B. Number of packets output

  C. CRCs

  D. Giants

  E. Multicasts

  Correct Answer: C

  The metric that confirms a cabling issue is the CRCS (Cyclic Redundancy Check Errors) value. This value indicates the number of packets that failed the CRC check, which is a mathematical algorithm used to detect errors in the data transmitted over the cable. A high number of CRCS errors indicates that there may be a problem with the cabling, such as a loose or damaged cable. In this case, the router interface has recorded 183 CRCS errors, which suggests that there may be a cabling issue that needs to be investigated.

• Question 916:

  The management team needs to ensure unnecessary modifications to the corporate network are not permitted and version control is maintained. Which of the following documents would BEST support this?

  A. An incident response plan

  B. A business continuity plan

  C. A change management policy

  D. An acceptable use policy

  Correct Answer: C

  - Change Management Policy: This policy sets out the rules and guidelines for making changes to the network, including who is authorized to make changes, how changes are requested and approved, and how changes are documented.

• Question 917:

  An IT director is setting up new disaster and HA policies for a company. Limited downtime is critical to operations. To meet corporate requirements, the director set up two different datacenters across the country that will stay current on data and applications. In the event of an outage, the company can immediately switch from one datacenter to another. Which of the following does this BEST describe?

  A. A warm site

  B. Data mirroring

  C. Multipathing

  D. Load balancing

  E. A hot site

  Correct Answer: E

  A hot site is a leased facility that contains all the resources needed for full operation. This environment includes computers, raised flooring, full utilities, electrical and communications wiring, networking equipment, and uninterruptible power supplies (UPSs). The only resource that must be restored at a hot site is the organization's data, usually only partially. It should only take a few minutes to bring a hot site to full operation.

  Although a hot site provides the quickest recovery, it is the most expensive to maintain. In addition, it can be administratively hard to manage if the organization requires proprietary hardware or software. A hot site requires the same security controls as the primary facility and full redundancy, including hardware, software, and communication wiring.

• Question 918:

  Which of the following is MOST likely to generate significant East-West traffic in a datacenter?

  A. A backup of a large video presentation to cloud storage for archival purposes

  B. A duplication of a hosted virtual server to another physical server for redundancy

  C. A download of navigation data to a portable device for offline access

  D. A query from an IoT device to a cloud-hosted server for a firmware update

  Correct Answer: B

  East-west traffic, in a networking context, is the transfer of data packets from server to server within a data center. The term east-west for this type of traffic comes from network diagram drawings that usually depict local area network (LAN) traffic horizontally

• Question 919:

  A technician wants to deploy a new wireless network that comprises 30 WAPs installed throughout a three-story office building. All the APs will broadcast the same SSID for client access. Which of the following BEST describes this deployment?

  A. Extended service set

  B. Basic service set

  C. Unified service set

  D. Independent basic service set

  Correct Answer: A

  Extended Service Set is configured on multiple access points to form an extended service area. The question states there is 30 wireless access points

• Question 920:

  A technician is troubleshooting a network switch that seems to stop responding to requests intermittently whenever the logging level is set for debugging. Which of the following metrics should the technician check to begin troubleshooting the issue?

  A. Audit logs

  B. CPU utilization

  C. CRC errors

  D. Jitter

  Correct Answer: B

  CPU utilisation is more of a metric. Additionally it has stated that it is only happening when the logging level is set for debugging. Given this will heavily utilise the CPU then that seems the logical thing to check
