DRAG DROP (Drag and Drop is not supported)
[Cisco Equipment and Related Hardware]



Refer to the exhibit. Drag and drop the functions from the left onto the corresponding internal memory components on the right.

  1. See Explanation for the Answer.

Answer(s): A

Explanation:



NVRAM Startup configuration
RAM Running configuration
ROM Bootstrap code, POST code, ROM monitor

Flash memory Cisco IOS software, backup configuration

Each memory type in a Cisco device serves a specific function in the boot process and runtime operation. NVRAM retains configuration across reboots, RAM is volatile and holds active configs, ROM handles initial boot tasks, and flash stores the operating system.

This content is covered thoroughly in "Cisco Equipment and Related Hardware" in the FLDTEC curriculum. Here's the breakdown:
ROM (Read-Only Memory)
Stores bootstrap code, POST (Power-On Self-Test), and ROM Monitor. These are essential for the device's initial power-on operations and recovery modes.
NVRAM (Non-Volatile RAM)

Holds the startup configuration file, which is loaded during the boot process.
Content remains intact after a reboot or power cycle.
RAM (Random Access Memory)
Stores the running configuration and current operational state of the router or switch. Also used for routing tables, ARP cache, and packet buffers. Data is lost when the device is powered off or rebooted.
Flash Memory
Contains the Cisco IOS image, system files, and can store backup configurations. It is a non-volatile storage, so it retains data after reboots.

Which two devices are most commonly used in a WAN environment? (Choose two.)

  1. Hubs
  2. Optical fiber converters
  3. Modems
  4. Network interface cards
  5. Wireless access points

Answer(s): B,C

Explanation:

In the context of Wide Area Networks (WANs), the key objective is to connect geographically separated networks using service provider infrastructure. The FLDTEC course emphasizes that WAN environments typically involve devices that can handle different physical transmission mediums and protocols.
Modems:
Modulate and demodulate analog signals to digital signals. Used in WAN environments to connect over analog lines like DSL or leased lines. Essential for interfacing between digital routers and analog telephone networks.
Optical Fiber Converters:
Also known as media converters, they are used to convert electrical signals to optical signals (and vice versa) for fiber transmission.
Common in WAN scenarios where long-distance high-speed transmission over fiber is required.

Incorrect Options:
A . Hubs: Obsolete Layer 1 devices used in LANs, not suitable for WANs. D . Network Interface Cards (NICs): Used in end devices for LAN connectivity. E . Wireless Access Points: Typically used in WLANs within local premises, not WAN infrastructure. This aligns with Cisco's WAN architecture fundamentals as highlighted in FLDTEC under "Cisco Equipment and Related Hardware."

What is the purpose of a subnet mask?

  1. Distinguishes the network and host segments
  2. Provides encryption for network traffic
  3. Determines the next-hop router
  4. Aids in route prioritization

Answer(s): A

Explanation:

A subnet mask is a 32-bit number used in IP networking to divide an IP address into network and host portions. This division is crucial for routing traffic within and between networks. The subnet mask works in tandem with the IP address to identify which part of the address refers to the network and which part refers to the host. This distinction allows for efficient IP address allocation and routing.
For example, in the IP address 192.168.1.10 with a subnet mask of 255.255.255.0, the first three octets (192.168.1) represent the network portion, while the last octet (10) identifies the specific host within that network.

DRAG DROP (Drag and Drop is not supported)
[Device Configuration and Verification]

Drag and drop the descriptions from the left onto the corresponding IPv4 addressing modes on the right.

  1. See Explanation for the Answer.

Answer(s): A

Explanation:



This content is aligned with IPv4 Addressing Fundamentals, detailed in the FLDTEC course under Device Configuration and Verification:
Unicast: A unicast address uniquely identifies a single host on a network. This is the most common address type used for standard communication between two devices. Broadcast: Broadcast addresses (e.g., 255.255.255.255 or subnet-specific broadcast) send traffic to all hosts in the network segment. Used for ARP requests and DHCP discovery. Multicast: Used to deliver a packet to a group of hosts interested in the data, without flooding the network like a broadcast. Multicast uses addresses from the range 224.0.0.0 to 239.255.255.255. Loopback: The loopback address (127.0.0.1) is reserved for local testing, ensuring that the TCP/IP stack is working properly without needing to access the network.

Refer to the exhibit.
What are two ways remote sites or branches connect to the enterprise campus network? (Choose two.)

  1. Access layer switches
  2. WAN links
  3. IPsec VPN tunnels
  4. Ad hoc Wi-Fi network
  5. LAN core switches

Answer(s): B,C

Explanation:

In enterprise networking, remote sites or branch offices connect to the central campus network using:
WAN Links: These are dedicated communication paths that connect geographically dispersed networks. WAN links can be leased lines, MPLS circuits, or other forms of long-distance connectivity that facilitate reliable data transmission between remote sites and the main campus. IPsec VPN Tunnels: Internet Protocol Security (IPsec) VPNs provide secure, encrypted tunnels over the public internet, allowing remote sites to connect to the enterprise network securely. This method is cost-effective and widely used for connecting branch offices to the central network infrastructure. Access layer switches (Option A) and LAN core switches (Option E) are components within a local network and do not facilitate remote connectivity. Ad hoc Wi-Fi networks (Option D) are temporary and lack the security and reliability required for enterprise-level remote connections.
