QUESTION: 6

A Cisco PoE switch is shown in the following image.
Which type of port will provide both data connectivity and power to an IP phone?

Port identified with number 2
Ports identified with numbers 3 and 4
Ports identified with number 6
Ports identified with number 7

Answer(s): C

Explanation:

In the provided image of the Cisco PoE switch, the ports identified with number 6 are the standard RJ-45 Ethernet ports typically found on switches that provide both data connectivity and Power over Ethernet (PoE). PoE ports are designed to supply power to devices such as IP phones, wireless access points, and other PoE-enabled devices directly through the Ethernet cable.

Ports:

· 2: Console port (for management and configuration)

· 3 and 4: Specific function ports (often for management)

· 6: RJ-45 Ethernet ports (capable of providing PoE)

· 7: SFP ports (for fiber connections, typically do not provide PoE)

Thus, the correct answer is C. Ports identified with number 6.

QUESTION: 7

During the data encapsulation process, which OSI layer adds a header that contains MAC addressing information and a trailer used for error checking?

Network
Transport
Data Link
Session

Answer(s): C

Explanation:

During the data encapsulation process, the Data Link layer of the OSI model is responsible for adding a header that contains MAC addressing information and a trailer used for error checking. The header typically includes the source and destination MAC addresses, while the trailer contains a Frame Check Sequence (FCS) which is used for error detection1.

The Data Link layer ensures that messages are delivered to the proper device on a LAN using hardware addresses and translates messages from the Network layer into bits for the Physical layer to transmit. It also controls how data is placed onto the medium and is received from the medium through the physical hardware.

QUESTION: 8

What is the purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch?

To enable the switch to act as a default gateway for the attached devices
To enable the switch to resolve URLs for the attached the devices
To enable the switch to provide DHCP services to other switches in the network
To enable access to the CLI on the switch through Telnet or SSH

Answer(s): D

Explanation:

The primary purpose of assigning an IP address to the management VLAN interface on a Layer 2 switch is to facilitate remote management of the switch. By configuring an IP address on the management VLAN, network administrators can access the switch's Command Line Interface (CLI) remotely using protocols such as Telnet or Secure Shell (SSH). This allows for convenient configuration changes, monitoring, and troubleshooting without needing physical access to the switch1.

Reference:

· Understanding the Management VLAN

· Cisco - VLAN Configuration Guide

· Remote Management of Switches

Assigning an IP address to the management VLAN interface (often the VLAN 1 interface by default) on a Layer 2 switch allows network administrators to remotely manage the switch using protocols such as Telnet or SSH. This IP address does not affect the switch's ability to route traffic between VLANs but provides a means to access and configure the switch through its Command Line Interface (CLI).

· A: The switch does not act as a default gateway; this is typically a function of a Layer 3 device like a router.

· B: The switch does not resolve URLs; this is typically a function of DNS servers.

· C: The switch can relay DHCP requests but does not typically provide DHCP services itself; this is usually done by a dedicated DHCP server or router.

Thus, the correct answer is D. To enable access to the CLI on the switch through Telnet or SSH.

QUESTION: 9

Which standard contains the specifications for Wi-Fi networks?

GSM
LTE
IEEE 802.11
IEEE 802.3
EIA/TIA 568A

Answer(s): C

Explanation:

The IEEE 802.11 standard contains the specifications for Wi-Fi networks. It is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in various frequencies, including but not limited to 2.4 GHz, 5 GHz, and 6 GHz1. This standard is maintained by the Institute of Electrical and Electronics Engineers (IEEE) and is commonly referred to as Wi-Fi. The standard has evolved over time to include several amendments that improve speed, range, and reliability of wireless networks.

QUESTION: 10

You want to store files that will be accessible by every user on your network.

Which endpoint device do you need?

Access point
Server
Hub
Switch

Answer(s): B

Explanation:

To store files that will be accessible by every user on a network, you would need a server. A server is a computer system that provides data to other computers. It can serve data to systems on a local network (LAN) or a wide network (WAN) over the internet. In this context, a file server would be set up to store and manage files, allowing users on the network to access them from their own devices1.

Reference:

What is a Server?

Understanding Servers and Their Functions

A server is a computer designed to process requests and deliver data to other computers over a local network or the internet. In this case, to store files that will be accessible by every user on the network, a file server is the appropriate endpoint device. It provides a centralized location for storing and managing files, allowing users to access and share files easily.

A . Access point: Provides wireless connectivity to a network.

C . Hub: A basic networking device that connects multiple Ethernet devices together, making them act as a single network segment.

D . Switch: A networking device that connects devices on a computer network by using packet switching to forward data to the destination device.

Thus, the correct answer is B. Server.
