2021 Sep ec0-350 exam question
Q81. You are having problems while retrieving results after performing port scanning during internal testing. You verify that there are no security devices between you and the target system. When both stealth and connect scanning do not work, you decide to perform a NULL scan with NMAP. The first few systems scanned shows all ports open.
Which one of the following statements is probably true?
A. The systems have all ports open.
B. The systems are running a host based IDS.
C. The systems are web servers.
D. The systems are running Windows.
Answer: D
Explanation: The null scan turns off all flags, creating a lack of TCP flags that should never occur in the real world. If the port is closed, a RST frame should be returned and a null scan to an open port results in no response. Unfortunately Microsoft (like usual) decided to completely ignore the standard and do things their own way. Thus this scan type will not work against systems running Windows as they choose not to response at all. This is a good way to distinguish that the system being scanned is running Microsoft Windows.
Q82. What are the two basic types of attacks?(Choose two.
A. DoS
B. Passive
C. Sniffing
D. Active
E. Cracking
Answer: BD
Explanation: Passive and active attacks are the two basic types of attacks.
Q83. What flags are set in a X-MAS scan?(Choose all that apply.
A. SYN
B. ACK
C. FIN
D. PSH
E. RST
F. URG
Answer: CDF
Explanation: FIN, URG, and PSH are set high in the TCP packet for a X-MAS scan
Q84. Lori has just been tasked by her supervisor conduct vulnerability scan on the corporate network. She has been instructed to perform a very thorough test of the network to ensure that there are no security holes on any of the machines. Lori’s company does not own any commercial scanning products, so she decides to download a free one off the Internet. Lori has never done a vulnerability scan before, so she is unsure of some of the settings available in the software she downloaded. One of the option is to choose which ports that can be scanned. Lori wants to do exactly what her boos has told her, but she does not know ports should be scanned.
If Lori is supposed to scan all known TCP ports, how many ports should she select in the software?
A. 65536
B. 1024
C. 1025
D. Lori should not scan TCP ports, only UDP ports
Answer: A
Explanation: In both TCP and UDP, each packet header will specify a source port and a destination port, each of which is a 16-bit unsigned integer (i.e. ranging from 0 to 65535).
Q85. SNMP is a protocol used to query hosts, servers, and devices about performance or health status data. This protocol has long been used by hackers to gather great amount of information about remote hosts.
Which of the following features makes this possible? (Choose two)
A. It used TCP as the underlying protocol.
B. It uses community string that is transmitted in clear text.
C. It is susceptible to sniffing.
D. It is used by all network devices on the market.
Answer: BC
Explanation: Simple Network Management Protocol (SNMP) is a protocol which can be used by administrators to remotely manage a computer or network device. There are typically 2 modes of remote SNMP monitoring. These modes are roughly 'READ' and 'WRITE' (or PUBLIC and PRIVATE). If an attacker is able to guess a PUBLIC community string, they would be able to read SNMP data (depending on which MIBs are installed) from the remote device. This information might include system time, IP addresses, interfaces, processes running, etc. Version 1 of SNMP has been criticized for its poor security. Authentication of clients is performed only by a "community string", in effect a type of password, which is transmitted in cleartext.

Q86. How do you defend against ARP spoofing?
A. Place static ARP entries on servers, workstation and routers
B. True IDS Sensors to look for large amount of ARP traffic on local subnets
C. Use private VLANS
D. Use ARPWALL system and block ARP spoofing attacks
Answer: ABC
Explanation: ARPWALL is a opensource tools will give early warning when arp attack occurs.
This tool is still under construction.
Q87. You are the IT Manager of a large legal firm in California. Your firm represents many important clients whose names always must remain anonymous to the public. Your boss, Mr. Smith is always concerned about client information being leaked or revealed to the pres or public. You have just finished a complete security overhaul of your information system including an updated IPS, new firewall, email encryption and employee security awareness training. Unfortunately, many of your firm’s clients do not trust technology to completely secure their information, so couriers routinely have to travel back and forth to and from the office with sensitive information.
Your boss has charged you with figuring out how to secure the information the couriers must transport. You propose that the data be transferred using burned CD’s or USB flash drives. You initially think of encrypting the files, but decide against that method for fear the encryption keys could eventually be broken.
What software application could you use to hide the data on the CD’s and USB flash drives?
A. Snow
B. File Snuff
C. File Sneaker
D. EFS
Answer: A
Explanation: The Snow software developed by Matthew Kwan will insert extra spaces at the end of each line. Three bits are encoded in each line by adding between 0 and 7 spaces that are ignored by most display programs including web browsers.
Q88. While footprinting a network, what port/service should you look for to attempt a zone transfer?
A. 53 UDP
B. 53 TCP
C. 25 UDP
D. 25 TCP
E. 161 UDP
F. 22 TCP
G. 60 TCP
Answer: B
Explanation: IF TCP port 53 is detected, the opportunity to attempt a zone transfer is there.
Q89. Eve decides to get her hands dirty and tries out a Denial of Service attack that is relatively new to her. This time she envisages using a different kind of method to attack Brownies Inc. Eve tries to forge the packets and uses the broadcast address. She launches an attack similar to that of fraggle. What is the technique that Eve used in the case above?
A. Smurf
B. Bubonic
C. SYN Flood
D. Ping of Death
Answer: A
Explanation: A fraggle attack is a variation of the smurf attack for denial of service in which the attacker sends spoofed UDP packets instead of ICMP echo reply (ping) packets to the broadcast address of a large network.
Q90. Henry is an attacker and wants to gain control of a system and use it to flood a target system with requests, so as to prevent legitimate users from gaining access. What type of attack is Henry using?
A. Henry is executing commands or viewing data outside the intended target path
B. Henry is using a denial of service attack which is a valid threat used by an attacker
C. Henry is taking advantage of an incorrect configuration that leads to access with higher-than-expected privilege
D. Henry uses poorly designed input validation routines to create or alter commands to gain access to unintended data or execute commands
Answer: B
Explanation: Henry’s intention is to perform a DoS attack against his target, possibly a DDoS attack. He uses systems other than his own to perform the attack in order to cover the tracks back to him and to get more “punch” in the DoS attack if he uses multiple systems.
