Bob, a network administrator at BigUniversity, realized that some students are connecting their notebooks in the wired network to have Internet access. In the university campus, there are many Ethernet ports
available for professors and authorized visitors but not for students.
He identified this when the IDS alerted for malware activities in the network. What should Bob do to avoid this problem?
A. Disable unused ports in the switches
B. Separate students in a different VLAN
C. Use the 802.1x protocol
D. Ask students to use the wireless network

A company’s policy requires employees to perform file transfers using protocols which encrypt traffic. You suspect some employees are still performing file transfers using unencrypted protocols because the
employees do not like changes.
You have positioned a network sniffer to capture traffic from the laptops used by employees in the data ingest department. Using Wireshark to examine the captured traffic, which command can be used as display
filter to find unencrypted file transfers?
A. tcp.port = = 21
B. tcp.port = 23
C. tcp.port = = 21 | | tcp.port = =22
D. tcp.port ! = 21
A. tcp.port = = 21
You just set up a security system in your network. In what kind of system would you find the following string of characters used as a rule within its configuration? alert tcp any any -> 192.168.100.0/24 21 (msg: ““FTP
on the network!””;)

A. Protocol analyzer
B. Network sniffer
C. Intrusion Prevention System (IPS)
D. Vulnerability scanner
A. Protocol analyzer
The Heartbleed bug was discovered in 2014 and is widely referred to under MITRE’s Common Vulnerabilities and Exposures (CVE) as CVE-2014-0160. This bug affects the OpenSSL implementation of the Transport

CompanyXYZ has asked you to assess the security of their perimeter email gateway. From your office in New York, you craft a specially formatted email message and send it across the Internet to an employee of
CompanyXYZ. The employee of CompanyXYZ is aware of your test. Your email message looks like this:
From: jim_miller@companyxyz.com
To: michelle_saunders@companyxyz.com Subject: Test message
Date: 4/3/2017 14:37
The employee of CompanyXYZ receives your email message.
This proves that CompanyXYZ’s email gateway doesn’t prevent what?
A. Email Masquerading
B. Email Harvesting
C. Email Phishing
D. Email Spoofing
D. Email Spoofing
Bob, a system administrator at TPNQM SA, concluded one day that a DMZ is not needed if he properly configures the firewall to allow access just to servers/ports, which can have direct internet access, and block the access to workstations.Bob also concluded that DMZ makes sense just when a stateful firewall is available, which is not the case of TPNQM SA.
In this context, what can you say?
A. Bob can be right since DMZ does not make sense when combined with stateless firewalls
B. Bob is partially right. He does not need to separate networks if he can create rules by destination IPs, one by one
C. Bob is totally wrong. DMZ is always relevant when the company has internet servers and workstations
D. Bob is partially right. DMZ does not make sense when a stateless firewall is available
C. Bob is totally wrong. DMZ is always relevant when the company has internet servers and workstations
Bob is acknowledged as a hacker of repute and is popular among visitors of “underground” sites.
Bob is willing to share his knowledge with those who are willing to learn, and many have expressed their interest in learning from him. However, this knowledge has a risk associated with it, as it can be used for
malevolent attacks as well.
In this context, what would be the most effective method to bridge the knowledge gap between the “black” hats or crackers and the “white” hats or computer security professionals? (Choose the test answer.)
A. Educate everyone with books, articles and training on risk analysis, vulnerabilities and safeguards.
B. Hire more computer security monitoring personnel to monitor computer systems and networks.
C. Make obtaining either a computer security certification or accreditation easier to achieve so more individuals feel that they are a part of something larger than life.
D. Train more National Guard and reservist in the art of computer security to help out in times of emergency or crises.
A. Educate everyone with books, articles and training on risk analysis, vulnerabilities and safeguards.
