CompTIA N10-008 Online Questions & Answers

• Question 1:

  A company has a geographically remote office. In order to connect to the internet, the company has decided to use a satellite WAN link. Which of the following is the GREATEST concern for this type of connection?

  A. Duplex
  B. Collisions
  C. Jitter
  D. Encapsulation
  C. Jitter

  ---

  Explanation/Reference:

  Jitter is the variation in delay of packet transmission over a network. In the case of a satellite WAN link, the signals travel a significant distance to reach the satellite in orbit and then back down to the ground station. This round-trip distance introduces noticeable latency, and variations in this latency are known as jitter.

• Question 2:

  An older web server on a screened subnet is serving unencrypted web traffic. The server is not capable of serving HTTPS traffic directly, but the firewall is capable of doing so. Which of the following should be done to encrypt all traffic coming into the web server from outside the network? (Choose two.)

  A. A certificate should be installed on the server.
  B. Incoming port 80 traffic at the firewall should be forwarded to port 443 on the server.
  C. Incoming port 80 traffic at the firewall should be forwarded to port 80 on the server.
  D. Incoming port 443 traffic at the firewall should be forwarded to port 80 on the server.
  E. A certificate should be installed on the firewall.
  F. A proxy server should be installed on the screened subnet.
  D. Incoming port 443 traffic at the firewall should be forwarded to port 80 on the server.
  E. A certificate should be installed on the firewall.

  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. 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.

  

• Question 4:

  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
  E. A hot site

  ---

  Explanation/Reference:

  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 5:

  Which of the following is most likely to be implemented to actively mitigate intrusions on a host device?

  A. HIDS
  B. NIDS
  C. HIPS
  D. NIPS
  C. HIPS

  ---

  Explanation/Reference:

  HIPS is designed to operate on individual host devices (like workstations, servers, etc.) and can actively prevent and mitigate intrusions. It not only detects malicious activities but also has the capability to automatically take action against these threats, such as blocking network traffic or quarantining malware.

• Question 6:

  A network administrator is setting up a new phone system and needs to define the location where VoIP phones can download configuration files. Which of the following DHCP services can be used to accomplish this task?

  A. Scope options
  B. Exclusion ranges
  C. Lease time
  D. Relay
  A. Scope options

  ---

  Explanation/Reference:

  A DHCP scope option can be used to specify the location of configuration files for VoIP phones, by including the address of the file server as an option in the DHCP scope. The DHCP server can then provide this information to the VoIP phones when they request an IP address, so that they know where to download the configuration files from. This allows the administrator to centrally manage the configuration of the phones, rather than having to manually configure each one.

• Question 7:

  A Fortune 500 firm is deciding On the kind or data center equipment to install given its five- year budget Outlook. The Chief Information comparing equipment based on the life expectancy Of different models. Which of the following concepts BEST represents this metric?

  A. MTBF
  B. MTRR
  C. RPO
  D. RTO
  A. MTBF

• Question 8:

  A desktop support department has observed slow wireless speeds for a new line of laptops using the organization's standard image. No other devices have experienced the same issue. Which of the following should the network administrator recommend troubleshooting FIRST to resolve this issue?

  A. Increasing wireless signal power
  B. Installing a new WAP
  C. Changing the protocol associated to the SSID
  D. Updating the device wireless drivers
  D. Updating the device wireless drivers

  ---

  Explanation/Reference:

  Wireless drivers can affect the performance and compatibility of your wireless connection5. If only a new line of laptops using the organization's standard image has experienced slow wireless speeds, it could be that their wireless drivers are outdated or incompatible with the network. Updating the device wireless drivers could resolve this issue. Wireless drivers play an important role in the performance of a wireless connection, as they control how the device interacts with the wireless network. If the laptops in question are using an outdated version of the wireless driver, it could be causing the slow speeds. The network administrator should recommend updating the device wireless drivers first to see if this resolves the issue.

• Question 9:

  A network administrator is troubleshooting an issue on a newly configured college campus network. A Linux workstation can connect to the internet, but it fails to connect to the campus intranet, which is located on another campus. Which of the following commands should the administrator run next to troubleshoot the connection?

  A. ifconfig
  B. traceroute
  C. nmap
  D. dig
  B. traceroute

• Question 10:

  A network technician is working to upgrade an existing wireless system in order to improve the coverage of APs throughout the building. Which of the following should the technician perform to determine the optimal placement of APs for the new wireless system?

  A. Cable testing
  B. Network assessment
  C. Site survey
  D. Packet capture
  C. Site survey
