QUESTION: 9

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.

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.

QUESTION: 10

[Cisco Equipment and Related Hardware]

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

Access layer switches
WAN links
IPsec VPN tunnels
Ad hoc Wi-Fi network
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.

QUESTION: 11

[Cisco Equipment and Related Hardware]
When should a crossover UTP cable be used instead of a straight-through cable when connecting network devices?

To connect electrically like devices
To connect a PC to a wireless access point
To connect a switch to a router
To connect electrically unlike devices

Answer(s): A

Explanation:

A crossover UTP (Unshielded Twisted Pair) cable is used to connect two similar devices directly. This includes:
Switch to switch
Router to router

PC to PC
The crossover cable reverses the transmit and receive pairs, allowing for proper communication between like devices without the need for an intermediary device. Conversely, a straight-through cable is used to connect dissimilar devices, such as:
PC to switch
Router to switch
PC to router
This cable maintains the same wiring on both ends, suitable for connecting different types of devices. Therefore, when connecting electrically like devices, a crossover cable is appropriate.

QUESTION: 12

[Cisco IOS Software Basics]
How many bits are borrowed from the default host portion of the address to create subnets in a Class B network with a subnet mask 255.255.255.0?

3 bits
5 bits
3 bits
8 bits

Answer(s): D

Explanation:

In a Class B network, the default subnet mask is 255.255.0.0, which allocates:
16 bits for the network portion
16 bits for the host portion
When the subnet mask is changed to 255.255.255.0, it becomes:
24 bits for the network portion
8 bits for the host portion
This indicates that 8 bits have been borrowed from the host portion to create additional subnets. Borrowing bits allows for the division of the original network into smaller sub-networks, enhancing organization and security within the network.

QUESTION: 13

[Cisco Equipment and Related Hardware]
What is the function of an access layer device?

Provides high-speed data transport between buildings or different parts of the campus
Serves as the entry point for end-user devices to connect to the network
Provides secure external access to internal network components
Connects remote offices to the main corporate network

Answer(s): B

Explanation:

In the hierarchical network design model, the access layer is the first layer and serves as the entry point for end-user devices to connect to the network. This layer connects user devices such as PCs, IP phones, wireless access points, printers, and scanners to the network. It facilitates the initial connection between end-user devices and the network infrastructure. The access layer also enforces security policies and provides services such as VLAN membership, port security, and Quality of Service (QoS).
Options A, C, and D refer to functions typically associated with the core or distribution layers, or with WAN connectivity, rather than the access layer.

QUESTION: 14

[Wireless Device Support]
Which term describes the physical range of radio frequency coverage provided by an access point in a wireless topology?

Service Set Identifier (SSID)
Basic Service Area (BSA)
Wireless LAN (WLAN)
Wireless LAN Controller (WLC)

Answer(s): B

Explanation:

In wireless networking, the Basic Service Area (BSA) refers to the physical area of radio frequency coverage provided by an access point (AP) in a Basic Service Set (BSS). The BSA defines the coverage area where wireless clients can connect to the network through the AP. The size and shape of a BSA depend on various factors, including the AP's transmit power, antenna type, and physical environment.
Option A, the Service Set Identifier (SSID), is the network name broadcast by the AP. Option C, Wireless LAN (WLAN), refers to the overall wireless network. Option D, Wireless LAN Controller (WLC), is a device that manages multiple APs in a network.

QUESTION: 15

[Device Configuration and Verification]

Which two configuration parameters are most critical to ensure optimal performance when configuring a network port for a newly installed IP phone in an enterprise environment? (Choose two.)

VLAN assignment
Link aggregation
Spanning Tree Protocol
Power over Ethernet
QoS classification

Answer(s): A,D

Explanation:

When configuring a network port for a newly installed IP phone, two critical parameters to ensure optimal performance are:
VLAN Assignment: Assigning the correct VLANs is essential for segregating voice and data traffic. Typically, a separate voice VLAN is configured to prioritize voice traffic and enhance security. Power over Ethernet (PoE): PoE allows the switch to supply power to the IP phone over the same Ethernet cable used for data transmission. This eliminates the need for separate power supplies and simplifies installation.
While QoS classification (Option E) is important for prioritizing voice traffic, it is typically configured at a broader network level. Link aggregation (Option B) and Spanning Tree Protocol (Option C) are more relevant to network redundancy and loop prevention, respectively, and are not directly critical for the initial configuration of an IP phone port.
