1. Question 201 · 610 in bank

   Which of the following network cables involves bouncing light off of protective cladding?

   • ATwinaxial
   • BCoaxial
   • CSingle-mode
   • DMultimode

   Show answer

   Answer: D

   Explanation

   The correct answer is D. Multimode. Explanation: Multimode fiber optic cables use a larger core (typically 50 or 62.5 microns) that allows light signals to travel in multiple paths (modes). These signals bounce off the protective cladding (due to total internal reflection) as they propagate, which is a defining characteristic of multimode fibers. In contrast, single-mode fiber (C) has a much smaller core (9 microns) and uses a single, direct path for light with minimal reflection. Twinaxial (A) and Coaxial (B) cables transmit electrical signals, not light, and are unrelated to fiber optics. Thus, multimode fiber explicitly relies on bouncing light off the cladding to transmit data.

   Which of the following would allow a network administrator to analyze attacks coming from the internet without affecting latency?

   • AIPS
   • BIDS
   • CLoad balancer
   • DFirewall

   Show answer

   Answer: B

   Explanation

   The correct answer is: B. IDS (Intrusion Detection System). An IDS monitors network traffic and analyzes attacks without actively interfering with the traffic flow, ensuring it does not affect latency. It operates passively, alerting the administrator to potential threats without blocking or modifying the traffic.

   A technician is troubleshooting wireless connectivity near a break room. Whenever a user turns on the microwave, connectivity to the user's laptop is lost. Which of the following frequency bands is the laptop most likely using?

   • A2.4GHz
   • B5GHz
   • C6GHz
   • D900MHz

   Show answer

   Answer: A

   Explanation

   The laptop is most likely using the **2.4 GHz frequency band**. Microwaves commonly operate on this frequency, which can cause interference with Wi-Fi signals. Switching to the 5 GHz band, if available, might help reduce this interference.

5. Question 205 · 610 in bank

   A network technician needs to install patch cords from the UTP patch panel to the access switch for a newly occupied set of offices. The patch panel is not labeled for easy jack identification. Which of the following tools provides the easiest way to identify the appropriate patch panel port?

   • AToner
   • BLaptop
   • CCable tester
   • DVisual fault locator

   Show answer

   Answer: A

   Explanation

   A. toner Generic term for two devices used together—a tone generator and a tone locator (probe)—to trace cables by sending an electrical signal along a wire at a particular frequency. The tone locator then emits a sound when it distinguishes that frequency. Also referred to as Fox and Hound

6. Question 206 · 610 in bank

   SIMULATION - A network administrator has been tasked with configuring a network for a new corporate office. The office consists of two buildings, separated by 50 feet with no physical connectivity. The configuration must meet the following requirements: Devices in both buildings should be able to access the Internet. Security insists that all Internet traffic be inspected before entering the network. Desktops should not see traffic destined for other devices. INSTRUCTIONS - Select the appropriate network device for each location. If applicable, click on the magnifying glass next to any device which may require configuration updates and make any necessary changes. Not all devices will be used, but all locations should be filled. If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

   

   

   This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

   Answer: See figure below

   Explanation

   You can't have a Wireless Range Extender without a WAP for it to connect to and repeat. The device at the bottom middle needs to be a WAP. Then the device in Bldg B can be a wireless range extender. It's ok since all Bldg B devices appear to be wireless capable (laptops, phone)

7. Question 207 · 610 in bank

   A network administrator received complaints of intermittent network connectivity issues. The administrator investigates and finds that the network design contains potential loop scenarios. Which of the following should the administrator do?

   • AEnable spanning tree.
   • BConfigure port security.
   • CChange switch port speed limits.
   • DEnforce 802.1Q tagging.

   Show answer

   Answer: A

   Explanation

   Spanning tree protocol or STP is used to help prevent loops. When a loop is identified, all traffic is blocked from going in or out of the interface to prevent a loop.

8. Question 208 · 610 in bank

   Which of the following routing technologies uses a successor and a feasible successor?

   • AIS-IS
   • BOSPF
   • CBGP
   • DEIGRP

   Show answer

   Answer: D

   Explanation

   The routing technology that uses the concepts of a successor and a feasible successor is Enhanced Interior Gateway Routing Protocol (EIGRP). EIGRP is a Cisco-proprietary routing protocol that uses these terms in its Dual (Diffusing Update Algorithm) to ensure efficient and loop-free path selection.

9. Question 209 · 610 in bank

   Which of the following best describes what an organization would use port address translation for?

   • AVLANs on the perimeter
   • BPublic address on the perimeter router
   • CNon-routable address on the perimeter router
   • DServers on the perimeter

   Show answer

   Answer: C

   Explanation

   C. Non-routable address on the perimeter router Port Address Translation allows multiple devices on a local network to be mapped to a single public IP address with different port numbers. This is particularly useful for: - **Non-routable address**: Providing access to devices with private, non-routable IP addresses (e.g., within a local network) via a single public IP address. This helps conserve public IP addresses and enables communication with external networks. PAT is a form of Network Address Translation (NAT) that extends the concept by utilizing port numbers to distinguish between different devices using the same public IP address.

10. Question 210 · 610 in bank

    A company is implementing a wireless solution in a high-density environment. Which of the following 802.11 standards is used when a company is concerned about device saturation and coverage?

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

    Show answer

    Answer: B

    Explanation

    The correct answer is: B. 802.11ax 802.11ax (Wi-Fi 6) is designed to address challenges in high-density environments where many devices connect to the network. It improves device saturation and coverage by introducing advanced features such as: OFDMA (Orthogonal Frequency Division Multiple Access): Allows multiple devices to share the same channel efficiently. MU-MIMO (Multi-User Multiple Input Multiple Output): Supports simultaneous communication with multiple devices. Target Wake Time (TWT): Improves power efficiency for connected devices. Enhanced signal performance and reduced interference in both 2.4GHz and 5GHz bands. This makes 802.11ax the most suitable standard for high-density environments
