• Question 521:

  An online gaming company needs a cloud solution that will allow for more virtual resources to be deployed when tournaments are held. The number of users who access the service increases during tournaments. The company also needs the resources to return to baseline levels once the resources are not needed in order to reduce cost. Which of the following cloud concepts would provide the best solution?

  A. Scalability
  B. Hybrid
  C. Multitenancy
  D. Elasticity

• Question 522:

  A systems administrator is looking for operating system information, running services, and network ports that are available on a server. Which of the following software tools should the administrator use to accomplish this task?

  A. nslookup
  B. nmap
  C. traceroute
  D. netstat
  B. nmap

• Question 523:

  Which of the following can be used to centrally manage credentials for various types of administrative privileges on configured network devices?

  A. SSO
  B. TACACS+
  C. Zero Trust
  D. Separation of duties
  E. Multifactor authentication
  B. TACACS+

  ---

  Explanation/Reference:

  TACACS+ is used to authenticate users and authorize access to network resources. This protocol provides greater network security by encrypting the authentication credentials and reducing the risk of unauthorized access. According to the CompTIA Network+ Study Manual, "TACACS+ is an authentication protocol used to centralize authentication and authorization for network devices. It is a more secure alternative to Telnet for handling logins and for granting privileges to users."

• Question 524:

  A network technician needs to implement a network security control on a switch. The solution needs to be non-invasive and prevent guests and unauthorized users from accessing the company's network Which of the following would BEST meet these requirements?

  A. Upgrading the firmware
  B. Disabling unused ports
  C. Reconfiguring the router access list
  D. Patching and updating
  C. Reconfiguring the router access list

• Question 525:

  After rebooting a PC, a user is no longer able to connect to the corporate network. As a test, the technician plugs a different laptop into the same network jack and receives an IP address of 169.254.112.137. Which of the following is MOST likely causing the issue?

  A. DHCP scope exhaustion
  B. Improper DNS setting
  C. Incorrect ACL setting
  D. Port-security violation
  A. DHCP scope exhaustion

• Question 526:

  A network technician is troubleshooting internet connectivity issues with users in a subnet. From a host, the technician runs tcpdump and then attempts to navigate to a website using a web browser. The technician receives the following output:

  

  Afterward, the browser displays an error. Which of the following explains this issue?

  A. A routing loop is within the network.
  B. The host is configured with incorrect DNS settings.
  C. A broadcast storm is occurring on the subnet.
  D. The host is missing a route to the website.
  D. The host is missing a route to the website.

• Question 527:

  Which of the following would an organization MOST likely have employees sign before granting access to confidential data?

  A. An AUP
  B. A BYOD policy
  C. An NDA
  D. A PUA
  C. An NDA

• Question 528:

  Which of the following describes the BEST device to configure as a DHCP relay?

  A. Bridge
  B. Router
  C. Layer 2 switch
  D. Hub
  B. Router

  ---

  Explanation/Reference:

  A layer 3 switch would have received my vote but not a Data Link layer 2 switch. Routers, IP assignments (DHCP) occur at network layer.

• Question 529:

  A user has just received a call from someone claiming to be from the company help desk and asking for password information to assist the user with a password reset. Company policy, however, states the help desk will not ask for password information. Which of the following has the user just experienced?

  A. Logic bomb
  B. Social engineering
  C. Phishing
  D. Insider threat
  B. Social engineering

• Question 530:

  Users in a remote office report that corporate web server pages are taking a long time to load, whereas users in the main corporate office do not have any issues. Which of the following is the best metric for a network administrator to check?

  A. Jitter across the network
  B. Hop-by-hop network latency
  C. Server interface CRC errors
  D. Server NetFlow data
  B. Hop-by-hop network latency

  ---

  Explanation/Reference:

  The best metric for a network administrator to check is hop-by-hop network latency. This is because network latency is the time it takes for a packet to travel from the source to the destination, and it affects the loading speed of web pages. Hop-by-hop network latency measures the latency between each pair of routers or switches along the network path, and it can help identify where the delay is occurring. By checking the hop-by- hop network latency, the network administrator can determine if the problem is caused by a slow or congested link, a misconfigured or faulty device, or a routing issue. Jitter is the variation in latency over time, and it affects the quality of voice and video applications. Jitter does not directly affect the loading speed of web pages, and it is not a useful metric for troubleshooting this issue. Server interface CRC errors are errors that occur when the cyclic redundancy check (CRC) of a packet does not match the expected value, indicating data corruption. Server interface CRC errors can affect the reliability and integrity of data transmission, and they can be caused by faulty cables, connectors, or interfaces. Server interface CRC errors do not necessarily affect the loading speed of web pages, unless they are severe enough to cause retransmissions or packet loss. Server NetFlow data is data that is collected and analyzed by the NetFlow protocol, which monitors and reports on network traffic flows. Server NetFlow data can provide information on the volume, type, and direction of traffic that is sent or received by the server, as well as the source and destination IP addresses, ports, and protocols. Server NetFlow data can help identify network usage patterns, trends, and anomalies, but it does not measure the latency or performance of the network.
