   A technician is installing the Wi-Fi infrastructure for legacy industrial machinery at a warehouse. The equipment only supports 802.11a and 802.11b standards. Speed of transmission is the top business requirement. Which of the following is the correct maximum speed for this scenario?

   • A11Mbps
   • B54Mbps
   • C128Mbps
   • D144Mbps

   Show answer

   Answer: B

   Explanation

   802.11b can handle 11mbps but 802.11a can handle 54mbps if using 5ghz. So, the maximum using 802.11a and 802.11b is 54mbps.

3. Question 293 · 871 in bank

   Due to concerns around single points of failure, a company decided to add an additional WAN to the network. The company added a second MPLS vendor to the current MPLS WAN and deployed an additional WAN router at each site. Both MPLS providers use OSPF on the WAN network, and EIGRP is run internally. The first site to go live with the new WAN is successful, but when the second site is activated significant network issues occur. Which of the following is the MOST likely cause for the WAN instability?

   • AA CDP neighbor has changed
   • BAsymmetrical routing
   • CA switching loop
   • DAn incorrect IP address

   Show answer

   Answer: B

   Explanation

   Asymmetrical routing is the most likely cause for the WAN instability. When two different routing protocols are used, like OSPF and EIGRP, it can cause asymmetrical routing, which results in traffic being routed differently in each direction. This can lead to instability in the WAN. A CDP neighbor change, a switching loop, or an incorrect IP address are not likely causes for WAN instability.

   During the troubleshooting of an E1 line, the point-to-point link on the core router was accidentally unplugged and left unconnected for several hours. However, the network management team was not notified. Which of the following could have been configured to allow early detection and possible resolution of the issue?

   • ATraps
   • BMIB
   • COID
   • DBaselines

   Show answer

   Answer: A

   Explanation

   A. Traps Traps are a mechanism for network devices to send unsolicited notifications of events or alarms to a management system. They can be configured to notify the network management team of specific events, such as the unplugging of a point-to-point link on a core router. This feature allows early detection and possible resolution of issues. MIB (Management Information Base) is a database of information that describes the management data of a device. OID (Object Identifier) is a unique identifier used to identify managed objects in the MIB. Baselines are a standard set of measurements used to establish normal network behavior, and they are used to compare current network activity against. Baselines can be used to detect abnormal behavior, but they are not as effective as traps for early detection of specific events.

5. Question 295 · 871 in bank

   Which of the following layers of the OSI model receives data from the application layer and converts it into syntax that is readable by other devices on the network?

   • ALayer 1
   • BLayer 3
   • CLayer 6
   • DLayer 7

   Show answer

   Answer: C

   Explanation

   The answer is 100% C, Layer 6, the Presentation Layer. Pulled from geeksforgeeks.org: "Presentation Layer is the 6th layer in the Open System Interconnection (OSI) model. This layer is also known as Translation layer, as this layer serves as a data translator for the network. The data which this layer receives from the Application Layer is extracted and manipulated here as per the required format to transmit over the network. The main responsibility of this layer is to provide or define the data format and encryption. The presentation layer is also called as Syntax layer since it is responsible for maintaining the proper syntax of the data which it either receives or transmits to other layer(s)."

   ARP spoofing would normally be a part of:

   • Aan on-path attack.
   • BDNS poisoning.
   • Ca DoS attack.
   • Da rogue access point.

   Show answer

   Answer: A

   Explanation

   ARP spoofing is a technique used in network attacks where an attacker sends falsified Address Resolution Protocol (ARP) messages over a local area network to link an attacker's MAC address with the IP address of a legitimate computer or server on the network. This allows the attacker to intercept network traffic meant for that legitimate computer or server, redirecting it to their own device to carry out various attacks. This is often part of an on-path attack where the attacker attempts to intercept and manipulate the network traffic between two endpoints.

9. Question 299 · 871 in bank

   A corporation is looking for a method to secure all traffic between a branch office and its data center in order to provide a zero-touch experience for all staff members who work there. Which of the following would BEST meet this requirement?

   • ASite-to-site VPN
   • BVNC
   • CRemote desktop gateway
   • DVirtual LANs

   Show answer

   Answer: A

   Explanation

   A. Site-to-site VPN (Virtual Private Network) A site-to-site VPN establishes a secure, encrypted connection between the branch office and the data center over the internet or another untrusted network. This solution ensures that all traffic between the branch office and the data center is secure and confidential. It's a suitable choice for providing a zero-touch experience for staff members, as once the VPN connection is established, users can access resources in the data center as if they were on the same local network. This allows for a seamless and secure connectivity experience.

10. Question 300 · 871 in bank

    A company cell phone was stolen from a technician's vehicle. The cell phone has a passcode, but it contains sensitive information about clients and vendors. Which of the following should also be enabled?

    • AFactory reset
    • BAutolock
    • CEncryption
    • DTwo-factor authentication

    Show answer

    Answer: C

    Explanation

    Undoubtedly the most quintessentially CompTIA question in this dump, possibly of all time. A multiple choice question with the option of four different correct answers. A. Should absolutely take place in this event via a remote wipe. B. Auto lock is the most ubiquitously enabled security measure listed and should always be enabled. C. The answer I believe they want, grammatically, it can be enabled so it beats A, it appears in the CompTIA Network+ Exam Objectives so it beats B. D. All that leaves is D, which should also be enabled where possible, however, generally people use their phones for MFA. Whenever you need to deal with 2FA, you go to your phone to do that. How can you use 2FA to access your "cell phone" if it is your phone that has Google authenticator on it for instance. It is possible but just weird, uncommon and not nearly as applicable as encryption.
