CompTIA N10-008 Online Questions & Answers

• Question 741:

  Which of the following protocols can be used to change device configurations via encrypted and authenticated sessions? (Select TWO).

  A. SNMPv3
  B. SSh
  C. Telnet
  D. IPSec
  E. ESP
  F. Syslog
  A. SNMPv3
  B. SSh

  ---

  Explanation/Reference:

  SNMPv3 (Simple Network Management Protocol version 3) is a protocol that provides secure access to network devices by encrypting and authenticating SNMP messages. It is used to manage and monitor network devices and can be used to change device configurations.

  SSH (Secure Shell) is a protocol that provides secure remote access to network devices by encrypting and authenticating sessions between devices. It is commonly used to access and manage network devices, such as routers and switches, and can be used to change device configurations.

• Question 742:

  Which of the following would be used to filter web traffic based on content?

  A. Proxy server
  B. Load balancer
  C. Media converter
  D. Access point
  A. Proxy server

• Question 743:

  Which of the following is a valid and cost-effective solution to connect a fiber cable into a network switch without available SFP ports?

  A. Use a media converter and a UTP cable
  B. Install an additional transceiver module and use GBICs
  C. Change the type of connector from SC to F-type
  D. Use a loopback adapter to make the connection
  A. Use a media converter and a UTP cable

  ---

  Explanation/Reference:

  Media converter converts fiber to copper connections

• Question 744:

  A server application requires large amounts of data to be sent at a consistent rate. Which of the following should an engineer most likely configure to meet these requirements?

  A. Link speed
  B. Jumbo frames
  C. Switch Virtual Interface
  D. Spanning tree
  B. Jumbo frames

  ---

  Explanation/Reference:

  Jumbo frames are Ethernet frames that have a payload size greater than the standard 1500 bytes. Jumbo frames can carry more data in each frame, which reduces the overhead and improves the throughput and efficiency of data transmission. Jumbo frames are commonly used in storage area networks (SANs), where large amounts of data need to be transferred between servers and storage devices

• Question 745:

  A network administrator is configuring a database server and would like to ensure the database engine is listening on a certain port. Which of the following commands should the administrator use to accomplish this goal?

  A. nslookup
  B. netstate -a
  C. ipconfi / a
  D. arp -a
  B. netstate -a

  ---

  Explanation/Reference:

  netstat -a is a command that displays information about active TCP connections and listening ports on a system. A network administrator can use netstat -a to check if the database engine is listening on a certain port, as well as verify if there are any connections established to or from that port.

• Question 746:

  Which of the following record types would be used to define where SIP is found?

  A. SRV
  B. CNAME
  C. A
  D. MX
  A. SRV

  ---

  Explanation/Reference:

  SRV (Service) record is used to define the location (hostname and port number) of servers for specified services. SIP (Session Initiation Protocol) is a signaling protocol used for controlling communication sessions such as voice and video calls over IP networks. Therefore, SRV record type is used to define where SIP is found by specifying the hostname and port number of the server that provides the SIP service.

• Question 747:

  Which of the following commands can be used to display the IP address, subnet address, gateway address, and DNS address on a Windows computer?

  A. netstat -a
  B. ifconfig
  C. ip addr
  D. ipconfig /all
  D. ipconfig /all

  ---

  Explanation/Reference:

  The ipconfig command is a utility that allows you to view and modify the network configuration of a Windows computer. By running the command "ipconfig /all", you can view detailed information about the network configuration of your computer, including the IP address, subnet mask, default gateway, and DNS server addresses.

  Option A (netstat -a) is a command that displays active network connections and their status, but it does not display IP address or other network configuration information. Option B (ifconfig) is a command used on Linux and Unix systems to view and modify network configuration, but it is not available on Windows. Option C (ip addr) is a command used on Linux and Unix systems to view and modify network configuration, but it is not available on Windows.

• Question 748:

  Which of the following devices is used to distribute network traffic equally over multiple links?

  A. Content filter
  B. DNS server
  C. Load balancer
  D. Proxy server
  C. Load balancer

• Question 749:

  A network manager wants to set up a remote access system for the engineering staff. Access to this system will be over a public IP and secured with an ACL.

  Which of the following best describes this system?

  A. VPN
  B. Secure Shell
  C. Jump server D. API
  A. VPN

  ---

  Explanation/Reference:

  Setting up a remote access system for the engineering staff that is accessible over a public IP and secured with an Access Control List (ACL) best describes a Virtual Private Network (VPN) setup. A VPN allows remote users to securely connect to the internal network over the internet by encrypting the data traffic.

• Question 750:

  A company's VoIP phone connection is cutting in and out. Which of the following should be configured to resolve this issue?

  A. 802.1Q tagging
  B. Jumbo frames
  C. Native VLAN
  D. Link aggregation
  A. 802.1Q tagging
