   Which of the following network topologies BEST describes a central device connected to multiple independent devices?

   • AMesh
   • BRing
   • CHub-and-spoke
   • DBus

   Show answer

   Answer: C

   Explanation

   C. Hub-and-spoke In a hub-and-spoke network topology, there is a central device (hub) connected to multiple independent devices (spokes). All communication between the independent devices is typically routed through the central hub. This topology is commonly used in scenarios where the central hub controls or coordinates communication among the connected devices. Therefore, the best description for a network topology with a central device connected to multiple independent devices is C. Hub-and-spoke.

   A network administrator is reviewing north-south traffic to determine whether a security threat exists. Which of the following explains the type of traffic the administrator is reviewing?

   • AData flowing between application servers
   • BData flowing between the perimeter network and application servers
   • CData flowing in and out of the data center
   • DData flowing between local on-site support and backup servers

   Show answer

   Answer: C

   Explanation

   C. Data flowing in and out of the data center North-south traffic typically refers to the data flow between the internal network (data center) and external networks, such as the internet or other remote networks. It involves data going in and out of the data center or internal network perimeter. Therefore, the correct answer is C. Data flowing in and out of the data center.

   A technician is troubleshooting a wireless connectivity issue in a small office located in a high-rise building. Several APs are mounted in this office. The users report that the network connections frequently disconnect and reconnect throughout the day. Which of the following is the MOST likely cause of this issue?

   • AThe AP association time is set too low
   • BEIRP needs to be boosted
   • CChannel overlap is occurring
   • DThe RSSI is misreported

   Show answer

   Answer: C

   Explanation

   It also says it's a SMALL office located in a high rise. Boosting the signal wouldn't help here unless a user connected to multiple networks throughout the building. A wireless device doesn't just drop its connection to attempt to connect to a stronger network it has never connected to before. A low AP association time on the other hand, would be an issue with multiple APs in a SMALL office.

   A network technician is installing a wireless network in an office building. After performing a site survey, the technician determines the area is very saturated on the 2.4GHz and the 5GHz bands. Which of the following wireless standards should the network technician implement?

   • A802.11ac
   • B802.11ax
   • C802.11g
   • D802.11n

   Show answer

   Answer: B

   Explanation

   802.11ac uses 5 GHz while 802.11g uses 2.4 GHz. Only 802.11n and 802.11ax use both, however, 802.11ax can handle a more saturated environment.

   A network technician discovered multiple failed logins on a production server. Upon investigation, the technician determined that a client plugged a personal laptop in to the corporate LAN, which allowed malware on the laptop to probe the network. Which of the following would have prevented this unauthorized device?

   • APort security
   • BBring your own device policy
   • CPatch management
   • DChanging default passwords

   Show answer

   Answer: A

   Explanation

   A. Port security Port security is a feature that can be implemented on network switches to control which devices are allowed to connect to the network through a specific port. It allows network administrators to specify the number of allowed MAC addresses on a port, and it can shut down the port or take other actions if it detects unauthorized devices. In this scenario, port security could have prevented the unauthorized personal laptop from connecting to the corporate LAN, as the port would have been configured to only allow the authorized MAC addresses associated with the company's devices. Therefore, the correct answer is A. Port security.

   Following a fire in a data center, an executive is concerned about the amount of data that must be reentered. Which of the following describes the executive's concern?

   • ARTO
   • BMTBF
   • CMMTR
   • DRPO

   Show answer

   Answer: D

   Explanation

   A recovery point objective (RPO) is the maximum length of time permitted that data can be restored from, which may or may not mean data loss. It is the age of the files or data in backup storage required to resume normal operations if a computer system or network failure occurs.

   A customer needs to distribute Ethernet to multiple computers in an office. The customer would like to use non-proprietary standards. Which of the following blocks does the technician need to install?

   • A110
   • B66
   • CBix
   • DKrone

   Show answer

   Answer: A

   Explanation

   A. 110 The 110 block is a non-proprietary wiring block commonly used for terminating and connecting Ethernet cables. It provides a standardized and widely accepted interface for distributing Ethernet connections in office environments. The 110 block is part of the ANSI/TIA/EIA-568 wiring standards, which are non-proprietary and widely adopted in the industry for structured cabling systems. Therefore, the technician needs to install a 110 block for distributing Ethernet to multiple computers in the office.

   A network engineer turned on logging to assist with troubleshooting a suspected configuration issue. Which of the following would provide the network engineer with the most informative log information?

   • AFATAL
   • BERROR
   • CDEBUG
   • DWARN

   Show answer

   Answer: C

   Explanation

   C. DEBUG In logging levels, DEBUG provides the most detailed and informative information for troubleshooting. Different logging levels serve various purposes: - FATAL: Indicates a very severe error that will lead to a program's termination. - ERROR: Indicates a less severe error, but still a problem that requires attention. - WARN (Warning): Indicates a potential issue that does not necessarily cause an error but should be noted. - DEBUG: Provides detailed information about the program's operation for debugging purposes. DEBUG logs are typically used during troubleshooting to gain insights into the system's behavior. Therefore, if the network engineer is troubleshooting a suspected configuration issue, enabling DEBUG-level logging would provide the most detailed information for analysis.
