Question 1

Question 33 of 90
You want to calculate the throughput of a large file transfer that you have completed. It took you 32 hours to transfer a 3 TB file. What would be the throughput if you use the following formula:
(3 * 1024 * 1024 * 8) / (32 * 60 * 60)
Answers
A.
321.12 Mb/sec
B.
95.39 Mb/Sec
C.
135.81 Mb/Sec
D.
218.45 Mb/sec

Answer 1

D.

218.45 Mb/sec

Question 2

Question 37 of 90
You have an IPv6 host that connects to a network and uses the stateless address autoconfiguration (SLAAC) process. What kind of packet is it expecting to receive in response to obtain its Internet layer configuration parameters?
Answers
A.
DHCPv6 packet
B.
Neighbor discovery packet
C.
Router discovery packet
D
Router advertisement packet

Answer 2

D.
Router advertisement packet

The SLAAC procedure begins when an IPv6 host sends out a router solicitation multicast request for its configuration parameters. Any IPv6 router on the network segment will respond with a router advertisement packet that contains its Internet layer configuration parameters.

Question 3

Question 46 of 90
You are given a network with two public IP addresses and several hundred internal private IP addresses. You are also told that one of the internal addresses belongs to a web server. You are asked to implement a translation scheme where all internal users will be able to access the Internet while Internet users will also be able to access the web server. Which of the following combination of features would you use for this implementation?
Answers
A.
1 to many NAT mapping for the web server and internal users
B.
1 to 1 static PAT mapping for the web server and 1 to many NAT mapping for the internal users
C.
1 to 1 static NAT mapping for the web server and 1 to many PAT mappings for the internal users
D.
1 to many PAT mappings for the web server and internal users

Answer 3

C.
1 to 1 static NAT mapping for the web server and 1 to many PAT mappings for the internal users

Show explanation Show answer
For the web server to be accessible from the Internet, a 1 to 1 static Network Address Translation (NAT) must be implemented. For the internal users to access the Internet, a 1 to many Port Address Translation (PAT) must be implemented. Although the term NAT is often used to refer to PAT, strictly speaking, they are two different implementations.

Question 4

Question 49 of 90
A user is complaining that the passphrase given for the wireless network is not functioning. You check from your device and discover that the passphrase is working correctly. What could be the probable cause?
Answers
A.
They are trying to connect to an incorrect SSID.
B.
There is a channel overlap.
C.
Their encryption method is incorrect.
D.
They are using the wrong frequency.

Answer 4

A. They are trying to connect to an incorrect SSID.

Each wireless network transmits a specific Service Set Identifier (SSID) that distinguishes it from other networks. When a wireless network is configured with a password, that password can only be used with the specific network for which it was configured. In the scenario described, the user connected to a different network with a different SSID and thus the configured password did not function.

Question 60 of 90
When you configure a NAS server on your network, which of the following is likely to happen? [Choose two that apply.]
Answers
A.
Network usage optimization
B.
Appears to the client OS as a disk
C.
Block-based storage without a file system
D.
Network accessible file storage space
E.
Storage and file system

Answer 5

B.
Appears to the client OS as a disk
D.
Network accessible file storage space

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to network clients. NAS is specialized for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance or a purpose-built specialized computer. It differs from SAN in that it also provides both storage and a file system whereas SAN provides only block-based storage for servers and leaves the file system concerns to the servers.

Question 6

Question 53 of 90
When you create a forward lookup zone, which two records are automatically created? [Choose two that apply.]
Answers
A.
NS
B.
SOA
C.
NS
D.
AAAA

Answer 6

A.
NS
B.
SOA

A forward lookup zone is the most common type of zone. DNS clients can use this zone to obtain such information as IP addresses that correspond to DNS domain names or services that are stored in the zone. This zone essentially performs the primary function of the DNS service. NS and SOA records are automatically created.

Question 7

Question 58 of 90
You need to install and configure a new wireless network for a client. The key requirement is to use the best security possible. The client is worried about the data confidentiality. Which of the protocols should you use in this scenario? [Choose all that apply].
Answers
A.
WPA
B.
MAC filtering
C.
TKIP
D.
WPA2
E.
EAP
F.
CCMP

Answer 7

D.
WPA
F.
CCMP

Show explanation Show answer
WPA2 which is currently mandatory on all Wi-Fi devices and provides CCMP and AES encryption support. CCMP provides data confidentiality.

Question 86 of 90
Which of the following technologies is considered a Wide Area Network (WAN) technology? [Choose two that apply.]
Answers
A.
xDSL
B.
Leased Line
C.
Wi-Fi
D.
Bluetooth

Answer 8

A
xDSL
B.
Leased Line

A Wide Area Network (WAN) is a computer network that extends over a large geographical distance. WANs are almost always established with leased telecommunications circuits. They are used to interconnect networks over large distances potentially spanning several tens to thousands of kilometers. WAN technologies include xDSL, Leased Lines, Cable, Frame Relay, ISDN and others.
