Bluetooth is an example of __________
Your Answer : (Not Answered)
Correct Answer : A
Explanation: Bluetooth is a wireless technology used to create a wireless personal area network for data transfer up to a distance of 10 meters. It operates on 2.45 GHz frequency band for transmission.
Which of the following is true when describing a global unicast address?
Your Answer : (Not Answered)
Correct Answer : B
Unlike unicast addresses, global unicast addresses are meant to be routed.
To enable RIPng, which of the following would you use?
Your Answer : (Not Answered)
Correct Answer : B
It's pretty simple to enable RIPng for IPv6. You configure it right on the interface where you want RIP to run with the ipv6 router rip number command.
Which of the following are advantages of using NAT?
1.Translation introduces switching path delays.
2.Conserves legally registered addresses.
3.Causes loss of end-to-end IP traceability.
4.Increases flexibility when connecting to the Internet.
5.Certain applications will not function with NAT enabled.
6.Reduces address overlap occurrence.
Your Answer : (Not Answered)
Correct Answer : D
NAT is not perfect, but there are some advantages. It conserves global addresses, which allow us to add millions of hosts to the Internet without "real" IP addresses. This provides flexibility in our corporate networks. NAT can also allow you to use the same subnet more than once in the same network without overlapping networks.
Which command will show you the summary of the NAT configuration?
Your Answer : (Not Answered)
Correct Answer : B
The show ip nat statistics command displays a summary of the NAT configuration as well as counts of active translation types, hits to an existing mapping, misses (causing an attempt to create a mapping), and expired translations.
Which command would you place on interface connected to the Internet?
Your Answer : (Not Answered)
Correct Answer : B
As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command ip nat inside. On the outside interface, you will use the command ip nat outside.
Which of the following protocols are used to configure trunking on a switch?
1.VLAN Trunk Protocol
2.VLAN
3.802.1Q
4.ISL
Your Answer : (Not Answered)
Correct Answer : C
Cisco has a proprietary trunking protocol called ISL. The IEEE version is 802.1Q.
What are reasons for creating OSPF in a hierarchical design?
1.To decrease routing overhead
2.To speed up convergence
3.To confine network instability to single areas of the network
4.To make configuring OSPF easier
Your Answer : (Not Answered)
Correct Answer : A
OSPF is created in a hierarchical design, not a flat design like RIP. This decreases routing overhead, speeds up convergence, and confines network instability to a single area of the network.
The corporate office sends you a new router to connect, but upon connecting the console cable, you see that there is already a configuration on the router. What should be done before a new configuration is entered in the router?
Your Answer : (Not Answered)
Correct Answer : C
Before you start to configure the router, you should erase the NVRAM with the erase startup-config command and then reload the router using the reload command.
You telnet to a router and make your necessary changes; now you want to end the Telnet session. What command do you type in?
Your Answer : (Not Answered)
Correct Answer : D
Since the question never mentioned anything about a suspended session, you can assume that the Telnet session is still open, and you would just type exit to close the session.
Which fields are contained within an IEEE Ethernet frame header?
1.Source and destination MAC address
2.Source and destination network address
3.Source and destination MAC address and source and destination network address
4.FCS field
Your Answer : (Not Answered)
Correct Answer : A
An Ethernet frame has source and destination MAC addresses, an Ether-Type field to identify the Network layer protocol, the data, and the FCS field that holds the answer to the CRC.
Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?
Your Answer : (Not Answered)
Correct Answer : C
A reliable Transport layer connection uses acknowledgments to make sure all data is transmitted and received reliably. A reliable connection is defined by a virtual circuit that uses acknowledgments, sequencing, and flow control, which are characteristics of the Transport layer (layer 4).
Which encapsulations can be configured on a serial interface?
1.Ethernet
2.Token Ring
3.HDLC
4.Frame Relay
5.PPP
Your Answer : (Not Answered)
Correct Answer : C
Ethernet and Token Ring are LAN technologies and cannot be configured on a serial interface. PPP, HDLC, and Frame Relay are layer 2 WAN technologies that are typically configured on a serial interface.
What is the frequency range of the IEEE 802.11g standard?
Your Answer : (Not Answered)
Correct Answer : C
The IEEE 802.11b and IEEE 802.11g standards both run in the 2.4GHz RF range.
What is the maximum distance running the lowest data rate for 802.11b?
Your Answer : (Not Answered)
Correct Answer : D
The IEEE 802.11b standard provides the lowest data rate at 1Mbps, but it also has the longest distance, which is about 350 feet.
What is the result of segmenting a network with a bridge (switch)?
1.It increases the number of collision domains.
2.It decreases the number of collision domains.
3.It increases the number of broadcast domains.
4.It decreases the number of broadcast domains.
5.It makes smaller collision domains.
6.It makes larger collision domains.
Your Answer : (Not Answered)
Correct Answer : A
Bridges break up collision domains, which would increase the number of collision domains in a network and also make smaller collision domains.
Which statement describes a spanning-tree network that has converged?
Your Answer : (Not Answered)
Correct Answer : C
Convergence occurs when all ports on bridges and switches have transitioned to either the forwarding or blocking states. No data is forwarded until convergence is complete. Before data can be forwarded again, all devices must be updated.
If your routing table has a static, a RIP, and an IGRP route to the same network, which route will be used to route packets by default?
Your Answer : (Not Answered)
Correct Answer : C
Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other found route. IGRP has an administrative distance of 100, and RIP has an administrative distance of 120, by default.
What layer in the TCP/IP stack is equivalent to the Transport layer of the OSI model?
Your Answer : (Not Answered)
Correct Answer : B
The four layers of the TCP/IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model.
What is the main reason the OSI model was created?
Your Answer : (Not Answered)
Correct Answer : C
The primary reason the OSI model was created was so that different networks could inter-operate.
