CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 591:

  A user reports that a new VoIP phone works properly, but the computer that is connected to the phone cannot access any network resources. Which of the following MOST likely needs to be configured correctly to provide network connectivity to the computer?

  A. Port duplex settings

  B. Port aggregation

  C. ARP settings

  D. VLAN tags

  E. MDIX settings

  Correct Answer: D

  VLAN (virtual LAN) tags are used to identify packets as belonging to a particular VLAN. VLANs are used to segment a network into logical sub-networks, and each VLAN is assigned a unique VLAN tag. If the VLAN tag is not configured correctly, the computer may not be able to access network resources.

• Question 592:

  A Chief Executive Officer and a network administrator came to an agreement with a vendor to purchase new equipment for the data center. A document was drafted so all parties would be informed about the scope of the project before it started. Which of the following terms BEST describes the document used?

  A. Contract

  B. Project charter

  C. Memorandum of understanding

  D. Non-disclosure agreement

  Correct Answer: C

• Question 593:

  A company joins a bank's financial network and establishes a connection to the clearinghouse servers in the range 192 168.124.0/27. An IT technician then realizes the range exists within the VM pool at the data center. Which of the following is the BEST way for the technician to connect to the bank's servers?

  A. NAT

  B. PAT

  C. CIDR

  D. SLAAC

  Correct Answer: A

• Question 594:

  Which of the following will reduce routing table lookups by performing packet forwarding decisions independently of the network layer header?

  A. MPLS

  B. mGRE

  C. EIGRP

  D. VRRP

  Correct Answer: A

  Multiprotocol Label Switching, or MPLS, is a networking technology that routes traffic using the shortest path based on "labels," rather than network addresses, to handle forwarding over private wide area networks. As a scalable and protocol-independent solution, MPLS assigns labels to each data packet, controlling the path the packet follows. MPLS greatly improves the speed of traffic, so users don't experience downtime when connected to the network.

• Question 595:

  An administrator is attempting to add a new system to monitoring but is unsuccessful. The administrator notices the system is similar to another one on the network; however, the new one has an updated OS version. Which of the following should the administrator consider updating?

  A. Management information bases

  B. System baseline

  C. Network device logs

  D. SNMP traps

  Correct Answer: A

  The MIBs contain information about the objects that can be managed on a device and their attributes. An updated OS version on the new system may have introduced changes to these objects and their attributes, so updating the MIBs would ensure that the monitoring system can accurately monitor the new system. The system baseline, network device logs, and SNMP traps may also be important, but updating the MIBs should be the first step in addressing the issue with adding the new system to monitoring.

• Question 596:

  A network administrator needs to provide evidence to confirm that recent network outages were caused by increased traffic generated by a recently released application. Which of the following actions will BEST support the administrator's response?

  A. Generate a network baseline report for comparison.

  B. Export the firewall traffic logs.

  C. Collect the router's NetFlow data.

  D. Plot interface statistics for dropped packets.

  Correct Answer: C

  NetFlow data provides information on network traffic, including the source and destination IP addresses, port numbers, and type of traffic, as well as bandwidth and volume of data transferred. This information can help the administrator determine if there was an increase in traffic from the recently released application and if it was the cause of the network outages.

• Question 597:

  A network administrator received a report staling a critical vulnerability was detected on an application that is exposed to the internet. Which of the following Is the appropriate NEXT step?

  A. Check for the existence of a known exploit in order to assess the risk

  B. Immediately shut down the vulnerable application server.

  C. Install a network access control agent on the server.

  D. Deploy a new server to host the application.

  Correct Answer: A

  The appropriate next step in this situation would be to check for the existence of a known exploit in order to assess the risk. This is important because it will help the network administrator determine the severity of the vulnerability and the potential impact it could have on the organization. Once the network administrator has assessed the risk, they can then take appropriate action to address the vulnerability. This might include patching the application, deploying a new server to host the application, or implementing other security measures to mitigate the risk. It is generally not advisable to immediately shut down the vulnerable application server, as this could disrupt business operations and cause significant downtime. Similarly, installing a network access control agent on the server may not be the most effective solution, as it would not address the underlying vulnerability.

• Question 598:

  A technician discovered that some information on the local database server was changed during a tile transfer to a remote server. Which of the following should concern the technician the MOST?

  A. Confidentiality

  B. Integrity

  C. DDoS

  D. On-path attack

  Correct Answer: B

  The technician should be concerned the MOST about integrity1. Integrity is the property of data that ensures it is accurate, complete, and consistent. When information on the local database server is changed during a file transfer to a remote server, it means that the integrity of the data has been compromised. This could be due to a malicious attack, a network error, a software bug, or a human mistake. The technician should investigate the cause of the data change and take appropriate measures to restore the integrity of the data and prevent future incidents.

• Question 599:

  Which of the following would MOST likely utilize PoE?

  A. A camera

  B. A printer

  C. A hub

  D. A modem

  Correct Answer: A

  The device that would MOST likely utilize PoE is a camera1. A camera is an example of a powered device (PD) that can receive both data and power from a single Ethernet cable connected to a power sourcing equipment (PSE), such as a switch or an injector. PoE cameras are commonly used for security and surveillance purposes, as they can reduce the cost and complexity of installation and maintenance. PoE cameras can support various features, such as motion detection, night vision, pan-tilt-zoom (PTZ), and remote control

• Question 600:

  Which of the following is used to elect an STP root?

  A. A bridge ID

  B. A bridge protocol data unit

  C. Interface port priority

  D. A switch's root port

  Correct Answer: A

  Root bridge

  1.

  Switch elected to act as a reference point for a spanning tree

  2.

  Switch with the lowest bridge ID (BID) is elected as the root bridge

  3.

  BID is made up of a priority value and a MAC address (with the lowest value considered root)
