   A technician needs to set up a wireless connection that utilizes MIMO on non-overlapping channels. Which of the following would be the best choice?

   • A802.11a
   • B802.11b
   • C802.11g
   • D802.11n

   Show answer

   Answer: D

   Explanation

   D. 802.11n Multiple Input Multiple Output (MIMO) technology is most effectively utilized by the 802.11n wireless standard. MIMO involves the use of multiple antennas at both the transmitter and receiver to improve communication performance. It allows for increased data throughput and improved wireless coverage. Therefore, if a technician needs to set up a wireless connection that utilizes MIMO on non-overlapping channels, the best choice would be D. 802.11n.

   Users have reported an issue connecting to a server over the network. A workstation was recently added to the network and configured with a shared USB printer. Which of the following is most likely causing the issue?

   • AThe switch is oversubscribed and cannot handle the additional throughput.
   • BThe printer is tying up the server with DHCP discover messages.
   • CThe web server's back end was designed for only single-threaded applications.
   • DThe workstation was configured with a static IP that is the same as the server.

   Show answer

   Answer: D

   Explanation

   D. The workstation was configured with a static IP that is the same as the server. If a workstation is configured with a static IP address that is the same as the server's IP address, it can lead to network conflicts and connectivity issues. This is known as an IP address conflict, where two devices on the same network have the same IP address. Therefore, the most likely cause of the reported issue is that the workstation and the server have conflicting IP addresses, leading to connectivity problems.

   A network engineer configured new firewalls with the correct configuration to be deployed to each remote branch. Unneeded services were disabled, and all firewall rules were applied successfully. Which of the following should the network engineer perform NEXT to ensure all the firewalls are hardened successfully?

   • AEnsure an implicit permit rule is enabled
   • BConfigure the log settings on the firewalls to the central syslog server
   • CUpdate the firewalls with current firmware and software
   • DUse the same complex passwords on all firewalls

   Show answer

   Answer: C

   Explanation

   C is CORRECT based on your argument. It should have been done first, but it was clearly not done yet. You can't "assume" this task was completed, when the question doesn't say so. In real life too, you can't "assume" that a tech updated the firewall, when nothing was mentioned in the ticketing system about it. Your manager will be upset if you "assume" work was done, without "knowing".

   Which of the following routing protocols uses an autonomous system number?

   • AIS-IS
   • BEIGRP
   • COSPF
   • DBGP

   Show answer

   Answer: D

   Explanation

   D. BGP (Border Gateway Protocol) An autonomous system (AS) is a collection of IP networks and routers under the control of a single entity that presents a common routing policy to the internet. BGP (Border Gateway Protocol) is the routing protocol commonly used to exchange routing and reachability information between autonomous systems on the internet. BGP uses an autonomous system number (ASN) to uniquely identify each autonomous system. Therefore, the correct answer is D. BGP.

6. Question 576 · 871 in bank

   A network administrator is designing a new network for a company that has frequent power spikes. The company wants to ensure that employees can keep working and the server will remain operational. Which of the following is the best solution for the administrator to recommend?

   • AGenerator
   • BCold site
   • CRedundant power supplies
   • DUninterruptible power supply

   Show answer

   Answer: D

   Explanation

   D. Uninterruptible power supply (UPS) To protect against power spikes and ensure continuity of operations during power outages, a UPS (Uninterruptible Power Supply) is the best solution. A UPS provides a temporary power source during electrical failures, allowing systems to shut down gracefully or continue operating for a short duration until power is restored or a generator takes over. While a generator (option A) is a solution for longer-term power outages, a UPS is typically used for short-term disruptions and provides immediate protection against power spikes and brief outages. Therefore, the best recommendation for the network administrator is D. Uninterruptible power supply (UPS).

   Select 2

   Which of the following OSI model layers are responsible for handling packets from the sources to the destination and checking for errors? (Choose two.)

   • APhysical
   • BSession
   • CData link
   • DNetwork
   • EPresentation
   • FApplication

   Show answer

   Answer: CD

   Explanation

   C. Data link D. Network Layers responsible for handling packets from source to destination and checking for errors in the OSI model are: C. Data link: This layer is responsible for framing packets, error detection, and handling the access to the physical network medium. It includes the logical link control (LLC) sublayer and the media access control (MAC) sublayer. D. Network: This layer is responsible for routing packets between different networks, logical addressing, and providing services such as fragmentation and error handling. It includes IP (Internet Protocol) in the case of the TCP/IP protocol suite. Therefore, the correct answers are C. Data link and D. Network.

9. Question 579 · 871 in bank

   Which of the following is the most cost-effective way for a network administrator to establish a persistent, secure connection between two facilities?

   • ASite-to-site VPN
   • BSSH tunnel
   • CAPI gateway
   • DDedicated line

   Show answer

   Answer: A

   Explanation

   A. Site-to-site VPN A site-to-site VPN (Virtual Private Network) is the most cost-effective way for a network administrator to establish a persistent, secure connection between two facilities. It allows secure communication over the internet by encrypting the data transmitted between the two locations. Site-to-site VPNs are a practical and economical solution for connecting geographically dispersed sites over the public internet while maintaining a high level of security.

10. Question 580 · 871 in bank

    Which of the following would most likely be considered for an IDF installation in a secure facility?

    • AFull-size body scanners
    • BIris scanner
    • CRFID badge readers
    • DSmart deadbolt

    Show answer

    Answer: C

    Explanation

    C. RFID badge readers An Intermediate Distribution Frame (IDF) in a secure facility typically houses networking equipment and connections. In this context, security measures are likely to involve access control to the networking infrastructure. RFID (Radio-Frequency Identification) badge readers are commonly used for secure access control in facilities. These readers can authenticate individuals based on RFID badges or cards, providing a secure means of access to network equipment. While options A (Full-size body scanners) and B (Iris scanner) are more associated with physical security measures for access to the facility, option D (Smart deadbolt) is related to securing physical doors and may not be directly tied to securing the network infrastructure in the IDF. Therefore, the most relevant security measure for an IDF installation in a secure facility is likely to be C. RFID badge readers.
