Which media type is least susceptible to external interference including EMI and RFI?

Wireless

Fiber optic

UTP

STP

On a wireless router, what is an SSID?

The default administrator account

The broadcast ID

He default communication protocol

A WAN encryption protocol

What is a reason to incorporate VLANs into a network?

To increase the number of available IP addresses

To increase the number of available Media Access Control (MAC) addresses.

To reduce the number of broadcast domains.

To reduce the number of nodes in a broadcast domain

What are two characteristics of VLANs? (Choose 2.)

A VLAN compartmentalizes a network and isolates traffic.

A single switch can service only a single VLAN.

VLANs act as though they are on the same LAN regardless of physical location.

A VLAN can logically address packets by using IP.

The fiber network connection between Building A and Building B is 550 meters. There is attenuation on the line. Which tool should you use to test this?

Time-domain reflectometer (DR)

Optical time-domain reflectometer (OTDR)

Toner

Multimeter

You are a network administrator at a small business. One morning at the start of business, you realize that no employees at the company can access external websites. However, all employees have the same intranet connected by a single router. You need to troubleshoot the problem. Which two actions should you complete? (Choose 2.)

Check the router for proper physical connectivity.

Check that each computer has a valid IP address.

Contact the internet service provider

Check for bad network adapters on individual computers

What is an advantage of dynamic routing?

It automatically enables DHCP.

It limits traffic derived from routing protocols.

It reduces broadcast traffic.

It automatically maintains routing tables.

What is a justification for using ST cable instead of UT cable to wire a network expansion?

You need the cable to be as light and flexible as possible

You need to reduce attenuation

You want to minimize the costs relating to the new installation

You are routing cables through an area with high external interference.

What are two characteristics of a mesh network topology? (Choose 2.)

It works best for networks with a large number of nodes. b. Every node connects to every other node on the networ

Every node connects to every other node on the network.

It is fault tolerant because of redundant connections.

It requires less cabling than either a star or ring topology

A computer is connected to a switch through a network patch panel by using copper cable. The computer is getting lower-than expected data speeds. Which two actions should you perform to identify the issue? (Choose 2.)

Search for broken wires in the cable by using a cable tester.

Tone the line from Unit A to Unit B.

Use an optical time-domain reflectometer (OTDR) to test the line.

Test the data speed of the cable.

You ping a server by using the fully qualified domain name (FQDN) and do not receive a response. You then ping the same server by using its IP address and receive a response Why do you receive a response on the second attempt but not on the first attempt?

The DHCP server is offline.

The DNS is not resolving

NSLOOKUP is stopped.

PING is improperly configured

What is a VPN?

A virtual network within your local area network (LAN)

A personal network for your use only

A communication tunnel between VLANs

A secure private connection over a public network

Your home computer is having problems accessing the internet. You suspect that your internet router's DHCP service is not functioning, so you check your computer's IP address. Which address indicates that your router's DHCP service is NOT functioning?

10.19.1.15

192.168.1.15

172.16.1.15

169.254.1.15

Which physical network topology provides fault-tolerant communication by providing redundant communication paths?

Bus

Ring

Star

Mesh

What is the primary purpose of a perimeter network?

To act as a secure location for deploying highly sensitive network servers

To monitor traffic between routed subnets in a private LAN

To provide a buffer area between a private intranet and the public internet

To act as a hidden location in which to deploy network clients

How is a router's static routing table updated?

Through direct action by the network administrator

With updates from the physically nearest routers

By monitoring adjacent subnets

From the RIP protocol after resetting the router

What happens when a client's DHCP-issued address expires?

The client disconnects from the network

The client attempts to renew its lease on the address.

The client continues to use the address until it is notified to stop

The client generates a new address valid to the subnet and requests approval from the DHCP

. In Linux, which command-line tool should you use to list a host's active incoming connections?

Netstat

Dig

host

ip addr

On a Windows computer, which utility should you use to determine whether your Domain Name System (DNS) service is properly resolving fully qualified domain names (FODNs) to IP addresses?

Ipconfig

Nbtstat

Nslookup

Netstat

In which range are IPv4 multicast addresses?

From 224.0.0.0 to 239.255.255.255
