Which of the following networks extends a private network across public networks?
Your Answer : (Not Answered)
Correct Answer : B
Explanation: A virtual private network extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.VPN provides enhanced security and online anonymity to users on the internet. It is also used to unblock websites which are unavailable in certain regions.
A __________ is a device that forwards packets between networks by processing the routing information included in the packet.
Your Answer : (Not Answered)
Correct Answer : C
Explanation: A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. They make use of routing protocols like RIP to find the cheapest path to the destination.
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 statement(s) about IPv4 and IPv6 addresses are true?
1.An IPv6 address is 32 bits long, represented in hexidecimal.
2.An IPv6 address is 128 bits long, represented in decimal.
3.An IPv4 address is 32 bits long, represented in decimal.
4.An IPv6 address is 128 bits long, represented in hexidecimal.
Your Answer : (Not Answered)
Correct Answer : C
IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.
To enable EIGRP, which of the following would you use?
1.Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
2.Router1(config-if)# ipv6 router rip 1
3.Router1(config)# ipv6 router eigrp 10
4.Router1(config-rtr)# no shutdown
5.Router1(config-if)# ipv6 eigrp 10
Your Answer : (Not Answered)
Correct Answer : B
Unlike RIPng and OSPFv3, you need to configure EIGRP both from global configuration mode and from interface mode, and you have to enable the command with the no shutdown command.
You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be?
Your Answer : (Not Answered)
Correct Answer : D
This question is a little vague, but the best answer is that the VLAN membership for the port is not configured.
If routers in a single area are configured with the same priority value, what value does a router use for the OSPF Router ID in the absence of a loopback interface?
Your Answer : (Not Answered)
Correct Answer : B
At the moment of OSPF process startup, the highest IP address on any active interface will be the Router ID (RID) of the router. If you have a loopback interface configured (logical interface), then that will override the interface IP address and become the RID of the router automatically.
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.
You have your laptop directly connected into a router's Ethernet port. Which of the following are among the requirements for the copy flash tftp command to be successful?
1.TFTP server software must be running on the router.
2.TFTP server software must be running on your laptop.
3.The Ethernet cable connecting the laptop directly into the router's Ethernet port must be a straight-through cable.
4.The laptop must be on the same subnet as the router's Ethernet interface.
5.The copy flash tftp command must be supplied the IP address of the laptop.
Your Answer : (Not Answered)
Correct Answer : B
Before you back up an IOS image to a laptop directly connected to a router's Ethernet port, make sure the TFTP server software is running on your laptop, that the Ethernet cable is a "crossover," and that the laptop is in the same subnet as the router's Ethernet port, and then you can use the copy flash tftp command from your laptop.
What is the subnetwork address for a host with the IP address 200.10.5.68/28?
Your Answer : (Not Answered)
Correct Answer : C
This is a pretty simple question. A /28 is 255.255.255.240, which means that our block size is 16 in the fourth octet. 0, 16, 32, 48, 64, 80, etc. The host is in the 64 subnet.
Which of the following types of connections can use full duplex?
1.Hub to hub
2.Switch to switch
3.Host to host
4.Switch to hub
5.Switch to host
Your Answer : (Not Answered)
Correct Answer : D
Hubs cannot run full-duplex Ethernet. Full duplex must be used on a point-to-point connection between two devices capable of running full duplex. Switches and hosts can run full duplex between each other, but a hub can never run full duplex.
How many non-overlapping channels are available with 802.11g?
Your Answer : (Not Answered)
Correct Answer : A
The IEEE 802.11g standard provides 3 non-overlapping channels.
What command will permit SMTP mail to only host 1.1.1.1?
Your Answer : (Not Answered)
Correct Answer : D
When trying to find the best answer to an access-list question, always check the access-list number and then the protocol. When filtering to an upper-layer protocol, you must use an extended list, numbers 100-199 and 2000-2699. Also, when you filter to an upper-layer protocol, you must use either tcp or udp in the protocol field. If it says ip in the protocol field, you cannot filter to an upper-layer protocol. SMTP uses TCP.
Network 206.143.5.0 was assigned to the Acme Company to connect to its ISP. The administrator of Acme would like to configure one router with the commands to access the Internet. Which commands could be configured on the Gateway router to allow Internet access to the entire network?
1.Gateway(config)# ip route 0.0.0.0 0.0.0.0 206.143.5.2
2.Gateway(config)# router rip
3.Gateway(config-router)# network 206.143.5.0
4.Gateway(config-router)# network 206.143.5.0 default
Your Answer : (Not Answered)
Correct Answer : D
There are actually three different ways to configure the same default route, but only two are shown in the answer. First, you can set a default route with the 0.0.0.0 0.0.0.0 mask and then specify the next hop, as in option A. Or you can use 0.0.0.0 0.0.0.0 and use the exit interface instead of the next hop. Finally, you can use option D with the ip default-network command.
You have the following routing table. Which of the following networks will not be placed in the neighbor routing table?
R 192.168.30.0/24 [120/1] via 192.168.40.1, 00:00:12, Serial0
C 192.168.40.0/24 is directly connected, Serial0
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.30.0 is directly connected, Loopback0
R 192.168.20.0/24 [120/1] via 192.168.40.1, 00:00:12, Serial0
R 10.0.0.0/8 [120/15] via 192.168.40.1, 00:00:07, Serial0
C 192.168.50.0/24 is directly connected, Ethernet0
Your Answer : (Not Answered)
Correct Answer : C
The network 10.0.0.0 cannot be placed in the next router's routing table because it already is at 15 hops. One more hop would make the route 16 hops, and that is not valid in RIP networking.
Which command will delete the contents of NVRAM on a router?
Your Answer : (Not Answered)
Correct Answer : D
The erase startup-config command erases the contents of NVRAM and will put you in setup mode if the router is restarted.
Which of the following allows a router to respond to an ARP request that is intended for a remote host?
Your Answer : (Not Answered)
Correct Answer : C
Proxy ARP can help machines on a subnet reach remote subnets without configuring routing or a default gateway.
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.
Which class of IP address has the most host addresses available by default?
Your Answer : (Not Answered)
Correct Answer : A
Class A addressing provides 24 bits for host addressing.
Where is a hub specified in the OSI model?
