A. 802.11a
B. 802.11b
C. 802.11g

D is correct. 802.11n uses multiple-input multiple-output (MIMO) technologies and orthogonal frequency-division multiplexing (OFDM). 802.11n is the only one of the listed wireless standards that uses MIMO.

A is incorrect. 802.11a uses OFDM but not MIMO.
B is incorrect. 802.11b uses direct-sequence spread spectrum (DSSS) instead of OFDM and it does not use  MIMO.
C is incorrect. 802.11g uses OFDM and DSSS, but not MIMO.

Q.Which of the following wireless standards has the fastest transfer rate?

A. 802.11a
B. 802.11b
C. 802.11g
D. 802.11n

Answer D is correct. 802.11n has a maximum transfer rate of 600 Mbps, which is faster than the other standards.

A is incorrect. 802.11a has a maximum transfer rate of 54 Mbps.
B is incorrect. 802.11b has a maximum transfer rate of 11 Mbps.

N10-005: Answer 3

Q.  During regular conference sessions, an 802.11g wireless network is overwhelmed with the amount of traffic it needs to process by wireless clients. Most of the additional traffic is from attendees’ mobile devices such as smart phones. What can be done to improve the performance of the wireless network?

A. Use a channel that doesn’t interfere with the smart phones
B. Use channel bonding
C. Switch to the 2.4 GHz frequency band
D. Add MIMO capabilities to the 802.11g network

Answer B is correct. Channel bonding can be used to increase the maximum transfer rate from 54 Mbps to 108 Mbps on 802.11g.
A is incorrect. If cordless telephones were interfering with a wireless networks, changing the channel would reduce the interference. However, smart phones are the wireless clients using the wireless network, and they are not interfering with the wireless network.
C is incorrect. 802.11g uses the 2.4 GHz frequency band already.
D is incorrect. 802.11g does not support multiple-input multiple-output (MIMO) with multiple antennas. MIMO is used with 802.11n.
Objective:  3.3 Compare and contrast different wireless standards.

Q.Attackers sent a targeted email attack to the President of a company. What best describes this attack?

A. Phishing
B. Spam
C. Whaling
D. Botnet

Answer C is correct. Whaling is a phishing attack that targets high-level executives and phishing is an email attack.

A is incorrect. Whaling is a phishing attack that targets high-level executives.
B is incorrect. Spam is unsolicited email and phishing and whaling attacks are sent as spam, but spam itself isn’t a targeted attack.
D is incorrect. A botnet is a group of computers joined to a network and criminals control them with command and control servers.

SY0-301: Answer 3

Q.  What can mitigate ARP poisoning attacks in a network?

A.  Disable unused ports on a switch
B. Man-in-the-middle
C. DMZ
D. VLAN segregation

Answer D is correct. Address Resolution Protocol (ARP) poisoning attacks modify the hardware addresses in ARP cache to redirect traffic, and virtual local area network (VLAN) segregation can limit the scope of these attacks.
A is incorrect. Disabling unused physical ports on a switch is a good security practice, but it doesn’t prevent ARP poisoning attacks.
B is incorrect. A man-in-the middle attack can interrupt traffic, insert malicious code, and ARP poisoning is one way to launch a man-in-the middle attack.
C is incorrect. A DMZ provides access to services from Internet clients, while segmenting access to an internal network.

N10-005: Exam Answer 1

Q.  What can you use to dynamically assign the same IP address to a printer configured as a network device?

A. DNS
B. DHCP reservation
C. SNMP
D. DHCP exclusion

B is correct. Dynamic Host Configuration Protocol (DHCP) is used to dynamically assign IP addresses to network devices including network printers that can be configured as DHCP clients. A DHCP reservation maps the IP address to the printer’s media access control (MAC) address. Once a DHCP reservation is configured,  DHCP will always issue the same IP address to this printer.

A is incorrect. Domain Name System (DNS) is used to resolve host names to IP addresses with A records (also called host records). DNS can also resolve IP addresses to host names with pointer (PTR) records, but it does not assign IP addresses.
C is incorrect. The Simple Network Management Protocol is used to administer and monitor network devices.
Dis incorrect.  A DHCP exclusion would be used if the printer is manually assigned an IP address within a DHCP scope and you want to ensure that the address is not issued to any other DHCP clients.

Objective:  2.3 Explain the purpose and properties of DHCP.

N10-005 Exam: Answer 2

Q.You are troubleshooting a computer system and you determine it has been assigned an IP address of 169.254.45.83. What does this indicate?

A. DNS could not be reached
B. DHCP could not be reached
C. The default gateway could not be reached
D. The computer’s firewall is enabled

Answer B is correct. An address starting with 169.254 is an Automatic Private Internet Protocol Addressing (APIPA) address and is assigned to a Dynamic Host Configuration Protocol (DHCP) client when a DHCP server cannot be reached. Any time you see an APIPA address, you know the computer is a DHCP client and it didn’t receive a DHCP lease.

A is incorrect. Domain Name System (DNS) is used for name resolution and would not cause a system to have an APIPA address.
C is incorrect. The default gateway is assigned by DHCP to a DHCP client and an APIPA address indicates that the client was unable to reach a DHCP server. Also, APIPA addresses do not assign a default gateway.
D is incorrect. Enabling the computer’s firewall would not block DHCP traffic and would not prevent the client from receiving a DHCP address.

Objective:  2.3 Explain the purpose and properties of DHCP.

N10-005: Answer 3

Q.  What function does DHCP provide on a network?

A. Dynamically assigns IP addresses
B. Resolves host names to IP addresses
C. Translates public IP addresses to private IP addresses
D. Filters traffic based on ACLs

Answer A is correct. Dynamic Host Configuration protocol (DHCP) dynamically assigns IP addresses and other TCP/IP configuration information such as the address of a Domain Name System (DNS) server and the address of the default gateway.
B is incorrect. DNS resolves host names to IP addresses with A (host) resource records.
C is incorrect. Network Address Translation (NAT) translates public IP addresses to private IP addresses and private IP addresses to public IP addresses.
D is incorrect. A firewall will filter traffic in and out of a network using access control lists (ACLs).
Objective:  2.3 Explain the purpose and properties of DHCP.
