CompTIA CompTIA Certifications SY0-601 Questions & Answers

• Question 171:

  HOTSPOT

  You received the output of a recent vulnerability assessment. Review the assessment and scan output and determine the appropriate remedialion(s} 'or choose devices.

  Remediation options may be selected multiple times, and some devices may require more than one remediation.

  Hot Area:

  

  Correct Answer:

  

• Question 172:

  HOTSPOT

  You are a security administrator investigating a potential infection on a network.

  INSTRUCTIONS

  Click on each host and firewall. Review all logs to determine which host originated the infection and then identify if each remaining host is clean or infected.

• Question 173:

  A security administrator discovers that an attack has been completed against a node on the corporate network. All available logs were collected and stored.

  You must review all network logs to discover the scope of the attack, check the box of the node(s) that have been compromised and drag and drop the appropriate actions to complete the incident response on the network. The environment is

  a critical production environment; perform the LEAST disruptive actions on the network, while still performing the appropriate incident responses.

  Instructions: The web server, database server, IDS, and User PC are clickable. Check the box of the node(s) that have been compromised and drag and drop the appropriate actions to complete the incident response on the network. Not all

  actions may be used, and order is not important. If at anytime you would like to bring back the initial state of the simulation, please select the Reset button. When you have completed the simulation, please select the Done button to submit.

  Once the simulation is submitted, please select the Next button to continue.

  

  Correct Answer:

  Database server was attacked; actions should be to capture network traffic and Chain of Custody.

  (The database server logs shows the Audit Failure and Audit Success attempts)It is only logical that all the logs will be stored on the database server and the least disruption action on the network to take as a response to the incident would be

  to check the logs (since these are already collected and stored) and maintain a chain of custody of those logs.

• Question 174:

  Task: Configure the firewall (fill out the table) to allow these four rules:

  Only allow the Accounting computer to have HTTPS access to the Administrative server.

  Only allow the HR computer to be able to communicate with the Server 2 System over SCP.

  Allow the IT computer to have access to both the Administrative Server 1 and Administrative Server 2

  

  Correct Answer:

  Use the following answer for this simulation task.

  Below table has all the answers required for this question.

  

  Firewall rules act like ACLs, and they are used to dictate what traffic can pass between the firewall and the internal network. Three possible actions can be taken based on the rule's criteria: Block the connection Allow the connection Allow the connection only if it is secured TCP is responsible for providing a reliable, one-to-one, connection-oriented session. TCP establishes a connection and ensures that the other end receives any packets sent. Two hosts communicate packet results with each other. TCP also ensures that packets are decoded and sequenced properly. This connection is persistent during the session. When the session ends, the connection is torn down. UDP provides an unreliable connectionless communication method between hosts. UDP is considered a best-effort protocol, but it's considerably faster than TCP. The sessions don't establish a synchronized session like the kind used in TCP, and UDP doesn't guarantee error-free communications. The primary purpose of UDP is to send small packets of information. The application is responsible for acknowledging the correct reception of the dat a. Port 22 is used by both SSH and SCP with UDP. Port 443 is used for secure web connections? HTTPS and is a TCP port. Thus to make sure only the Accounting computer has HTTPS access to the Administrative server you should use TCP port 443 and set the rule to allow communication between 10.4.255.10/24 (Accounting) and 10.4.255.101 (Administrative server1) Thus to make sure that only the HR computer has access to Server2 over SCP you need use of TCP port 22 and set the rule to allow communication between 10.4.255.10/23 (HR) and

  10.4.255.2 (server2) Thus to make sure that the IT computer can access both the Administrative servers you need to use a port and accompanying port number and set the rule to allow communication between:

  10.4.255.10.25 (IT computer) and 10.4.255.101 (Administrative server1) 10.4.255.10.25 (IT computer) and 10.4.255.102 (Administrative server2)

• Question 175:

  HOTSPOT

  For each of the given items, select the appropriate authentication category from the dropdown choices. Instructions: When you have completed the simulation, please select the Done button to submit.

  Hot Area:

  

  Correct Answer:

  

  Something you are includes fingerprints, retina scans, or voice recognition.

  Something you have includes smart cards, token devices, or keys.

  Something you know includes a passwords, codes, PINs, combinations, or secret phrases.

  Somewhere you are includes a physical location s or logical addresses, such as domain name, an IP address, or a MAC address.

  Something you do includes your typing rhythm, a secret handshake, or a private knock.

• Question 176:

  HOTSPOT

  For each of the given items, select the appropriate authentication category from the drop down choices. Select the appropriate authentication type for the following items:

  Hot Area:

  

  Correct Answer:

  

  Biometrics refers to a collection of physical attributes of the human body that can be used as identification or an authentication factor. Fingerprints and retinas are physical attributes of the human body.

  Two types of tokens exist, Time-based one-time password (TOTP) tokens and HMACbased one-time password (HOTP). TOTP tokens generate passwords at fixed time intervals, whereas HOTP tokens generate passwords not based on fixed

  time intervals but instead based on a non-repeating one-way function, such as a hash or HMAC operation.

  Smart cards can have Multi-factor and proximity authentication embedded into it.

  PAP allows for two entities to share a password in advance and use the password as the basis of authentication. The same goes for PIN numbers.

• Question 178:

  DRAG DROP

  A security auditor is reviewing the following output from file integrity monitoring software installed on a very busy server at a large service provider. The server has not been updates since it was installed. Drag and drop the log entry that identifies the first instance of server compromise.

• Question 179:

  HOTSPOT

  The security administrator has installed a new firewall which implements an implicit DENY policy by default. Click on the firewall and configure it to allow ONLY the following communication.

  1.

  The Accounting workstation can ONLY access the web server on the public network over the default HTTPS port. The accounting workstation should not access other networks.

  2.

  The HR workstation should be restricted to communicate with the Financial server ONLY, over the default SCP port

  3.

  The Admin workstation should ONLY be able to access the servers on the secure network over the default TFTP port.

  Instructions: The firewall will process the rules in a top-down manner in order as a first match The port number must be typed in and only one port number can be entered per rule Type ANY for all ports. The original firewall configuration can

  be reset at any time by pressing the reset button. Once you have met the simulation requirements, click save and then Done to submit.

  

  Hot Area:

  

  Correct Answer:

  

  

  Implicit deny is the default security stance that says if you aren't specifically granted access or privileges for a resource, you’re denied access by default.

  Rule #1 allows the Accounting workstation to ONLY access the web server on the public network over the default HTTPS port, which is TCP port 443.

  Rule #2 allows the HR workstation to ONLY communicate with the Financial server over the default SCP port, which is TCP Port 22

  Rule #3 and Rule #4 allow the Admin workstation to ONLY access the Financial and Purchasing servers located on the secure network over the default TFTP port, which is Port 69.
