1. Question 101 · 871 in bank

   A company hired a technician to find all the devices connected within a network. Which of the following software tools would BEST assist the technician in completing this task?

   • AIP scanner
   • BTerminal emulator
   • CNetFlow analyzer
   • DPort scanner

   Show answer

   Answer: A

   Explanation

   An IP scanner is a network tool used to discover and inventory devices connected to a network by scanning IP addresses within a specified range. It identifies active devices, provides information such as IP addresses, MAC addresses, device types, and sometimes operating systems. This tool is commonly used for network discovery and mapping, making it ideal for the technician's task of finding all connected devices within the network.

   A user in a branch office reports that access to all files has been lost after receiving a new PC. All other users in the branch can access fileshares. The IT engineer who is troubleshooting this incident is able to ping the workstation from the branch router, but the machine cannot, ping the router. Which of the following is MOST likely the cause of the incident?

   • AIncorrect subnet mask
   • BIncorrect DNS server
   • CIncorrect IP class
   • DIncorrect TCP port

   Show answer

   Answer: A

   Explanation

   - If the user's PC has an incorrect subnet mask, it may not be able to communicate with other devices on the network, including the router. This would explain why the user can't access any files, but other users in the branch can. - The fact that the IT engineer can ping the workstation from the branch router suggests that the workstation is on the same network segment as the router. However, the fact that the workstation cannot ping the router indicates that there may be an issue with the subnet mask.

   • AAn IPS
   • BA Layer 3 switch
   • CA router
   • DA wireless LAN controller

   Which of the following types of attacks can be used to gain credentials by setting up rogue APs with identical corporate SSIDs?

   • AVLAN hopping
   • BEvil twin
   • CDNS poisoning
   • DSocial engineering

   Show answer

   Answer: B

   Explanation

   evil twin, attacker AP setup with for example Starbucks1Guest to get you to attach, you still get out to internet but attacker can see all you do. FYI always use VPN when in public WIFI, or better yet NEVER EVER attach to any public WIFI use your cell service instead w/ VPN on of course.

6. Question 106 · 871 in bank

   Which of the following protocols is widely used in large-scale enterprise networks to support complex networks with multiple routers and balance traffic load on multiple links?

   • AOSPF
   • BRIPv2
   • CQoS
   • DSTP

   Show answer

   Answer: A

   Explanation

   RIP (Routing Information Protocol) is a very old (perhaps original?) routing protocol. We've had it in use since the 1980s. RIPv2 was introduced in the 1990s as a successor. Both are distance-vector protocols. As an example of their age, RIPv2 is limited to fifteen hops across a network, which is inadequate for modern use. OSPF (Open Shortest Path First) is a link-state protocol, and in common use today.

   A network engineer is investigating reports of poor network performance. Upon reviewing a report, the engineer finds hundreds of CRC errors on an interface. Which of the following is the MOST likely cause of these errors?

   • AA bad wire on the Cat 5e cable
   • BThe wrong VLAN assignment to the switchport
   • CA misconfigured QoS setting on the router
   • DBoth sides of the switch trunk set to full duplex

8. Question 108 · 871 in bank

   Which of the following is considered a physical security detection device?

   • ACameras
   • BBiometric readers
   • CAccess control vestibules
   • DLocking racks

   Show answer

   Answer: A

   Explanation

   It is rare any one of us gets to say this quite so triumphantly and dogmatically on account of the subjective nature of a lot of these questions but I can ASSURE you with complete certainty that the answer is A. Please navigate to the CompTIA Network+ n10-008 Exam Objectives. Look under section 4.5 "Explain the importance of physical security" Camera is listed under detection methods, case closed. The answer is A. I was formerly under the impression it was ACV, for those also labouring under that misapprehension, please consult the exam objectives and you'll find that Access Control Vestibules are listed as "Prevention Methods" and NOT detection methods. Physical was not the word to focus on, they're all physical methods.

9. Question 109 · 871 in bank

   A network is experiencing extreme latency when accessing a particular website. Which of the following commands will BEST help identify the issue?

   • Aipconfig
   • Bnetstat
   • Ctracert
   • Dping

   Show answer

   Answer: C

   Explanation

   Answer C is correct because the "tracert" command is short for "traceroute," the CLI command which determines the route a packet takes to its destination. Knowing which networks a packet travels through is essential in identifying latency when visiting a website. Answer A is incorrect because the "ipconfig" command lists the local device's TCP/IP and network adapter information. It will not list underlying reasons for network latency. Answer B is incorrect because the "netstat" command shows all active connection to the device but does not show the latency for packets in those connections. Answer D is incorrect because although it shows the latency for packets between a source and its destination, the question asks on how to help identify the issue, not identify what the issue is.

    A technician needs to configure a routing protocol for an internet-facing edge router. Which of the following routing protocols will the technician MOST likely use?

    • ABGP
    • BRIPv2
    • COSPF
    • DEIGRP

    Show answer

    Answer: A

    Explanation

    Border Gateway Protocol (BGP) is used to Exchange routing information for the internet and is the protocol used between ISP which are different ASes. The protocol can connect together any internetwork of autonomous system using an arbitrary topology.
