  12. How many host addresses are available on the 192.168.10.128/26 network?

    • 30
    • 32
    • 60
    • 62
    • 64
      Explanation:

      A /26 prefix gives 6 host bits, which provides a total of 64 addresses, because 26 = 64. Subtracting the network and broadcast addresses leaves 62 usable host addresses.

  13. Refer to the exhibit. What is a valid address on the PC for the default gateway?

    CCNA Cybersecurity Operations (Version 1.1) – Practice Final Exam Answers 2019 Full 100% 02

    CCNA Cybersecurity Operations (Version 1.1) – Practice Final Exam Answers 2019 Full 100% 02

    • 192.168.1.1
    • 192.168.0.1
    • 192.168.2.1
    • 192.168.255.1
      Explanation:

      The default gateway setting is the IP address of the router to which the host will send packets in order to reach remote networks. The default gateway address setting must be on the same logical network as the host IP address. In this case, the network of the host is 192.168.1.0 so the default gateway must also be on the 192.168.1.0 network.

  14. Refer to the exhibit. Which IPv4 address does the PC use for sending traffic to remote networks?

    CCNA Cybersecurity Operations (Version 1.1) – Practice Final Exam Answers 2019 Full 100% 03

    CCNA Cybersecurity Operations (Version 1.1) – Practice Final Exam Answers 2019 Full 100% 03

    • 192.168.1.2
    • 192.168.1.1
    • 127.0.0.1
    • 192.168.1.255
      Explanation:

      The default gateway setting is the IP address of the router to which the host will send packets that are destined for remote networks. In the routing table of a PC, the gateway address is the default gateway and must be on the same logical network as the host IP address, in this case 192.168.1.0. Thus the gateway address, which must be on the 192.168.1.0 network, is 192.168.1.1.

  15. A cybersecurity analyst believes that an attacker is announcing a forged MAC address to network hosts in an attempt to spoof the default gateway. Which command could the analyst use on the network hosts to see what MAC address the hosts are using to reach the default gateway?

    • netsat -r
    • route print
    • ipconfig /all
    • arp -a 
      Explanation:

      The command arp -a will display the MAC address table on a PC.

  16. Which value, that is contained in an IPv4 header field, is decremented by each router that receives a packet?

    • Differentiated Services
    • Fragment Offset
    • Header Length
    • Time-to-Live
      Explanation:

      When a router receives a packet, the router will decrement the Time-to-Live (TTL) field by one. When the field reaches zero, the receiving router will discard the packet and will send an ICMP Time Exceeded message to the sender.

  17. What information does an Ethernet switch examine and use to forward a frame?

    • destination IP address
    • source IP address
    • destination MAC address
    • source MAC address
      Explanation:

      A switch is a Layer 2 device that uses source MAC addresses to build a MAC address table (a CAM table) and destination MAC addresses to forward frames.

  18. A person coming to a cafe for the first time wants to gain wireless access to the Internet using a laptop. What is the first step the wireless client will do in order to communicate over the network using a wireless management frame?

    • agree

      Dst MAC: 00-D0-D3-BE-00-00

      Explanation:

      When a message sent from PCA to PCB reaches router R2, some frame header fields will be rewritten by R2 before forwarding to switch S2. The frames will contain the source MAC address of router R2 and the destination MAC address of PCB. The frames will retain the original IPv4 addressing applied by PCA which is the IPv4 address of PCA as the source address and the IPv4 address of PCB as the destination.

  20. What are three functions provided by the syslog service? (Choose three.)

    • to gather logging information for monitoring and troubleshooting
    • to select the type of logging information that is captured
    • to specify the destinations of captured messages
    • to periodically poll agents for data
    • to provide statistics on packets that are flowing through a Cisco device
    • to provide traffic analysis
      Explanation:

      There are three primary functions provided by the syslog service:

      1. gathering logging information
      2. selection of the type of information to be logged
      3. selection of the destination of the logged information
  21. Users report to the helpdesk that icons usually seen on the menu bar are randomly appearing on their computer screens. What could be a reason that computers are displaying these random graphics?

    • An access attack has occurred.
    • A virus has infected the computers.
    • A DoS attack has been launched against the network.
    • The computers are subject to a reconnaissance attack.
      Explanation:

      A virus such as this is harmless, but still needs to be removed. Other viruses can be destructive in that they modify or delete files on the local computer and possibly other computers on the network.

  22. Why does a worm pose a greater threat than a virus poses?

    • Worms run within a host program.
    • Worms are not detected by antivirus programs.
    • Worms directly attack the network devices.
    • Worms are more network-based than viruses are.
      Explanation:

      One major component of a worm is the propagation mechanism which replicates the worm and targets unprotected network devices. A virus requires a host program, but worms do not.

  23. Which two characteristics describe a virus? (Choose two.)

    • A self-replicating attack that is independently launched.
    • Malicious code that can remain dormant before executing an unwanted action.
    • Program code specifically designed to corrupt memory in network devices.
    • Malware that relies on the action of a user or a program to activate.
    • Malware that executes arbitrary code and installs copies of itself in memory.
      Explanation:

      A virus is malicious code that is attached to legitimate programs or executable files. Most viruses require end user activation, can lie dormant for an extended period, and then activate at a specific time or date. In contrast, a worm executes arbitrary code and installs copies of itself in the memory of the infected computer. The main purpose of a worm is automatic replication to spread quickly across a network. A worm does not require a host program to run.

  24. The IT department is reporting that a company web server is receiving an abnormally high number of web page requests from different locations simultaneously. Which type of security attack is occurring?

    • adware
    • DDoS
    • phishing
    • social engineering
    • spyware
      Explanation:

      Phishing, spyware, and social engineering are security attacks that collect network and user information. Adware consists, typically, of annoying popup windows. Unlike a DDoS attack, none of these attacks generate large amounts of data traffic that can restrict access to network services.

  25. A disgruntled employee is using Wireshark to discover administrative Telnet usernames and passwords. What type of network attack does this describe?

    • denial of service
    • port redirection
    • reconnaissance
    • trust exploitation
      Explanation:

      Wireshark is a free download that allows network packet inspection. Someone using this tool for malicious intent would be performing a reconnaissance attack. Through the capture of network packets, weak security network connectivity protocols such as Telnet can be caught, inspected, and then analyzed for detailed network information, including passwords.

  26. What is an essential function of SIEM?

    • providing reporting and analysis of security events
    • providing 24×7 statistics on packets flowing through a Cisco router or multilayer switch
    • monitoring traffic and comparing it against the configured rules
    • forwarding traffic and physical layer errors to an analysis device
      Explanation:

      SIEM provides real-time reporting and analysis of security events. SIEM provides administrators with details on sources of suspicious activity such as user information, device location, and compliance with security policies.

  27. What is the result of a DHCP starvation attack?

    • Legitimate clients are unable to lease IP addresses.
    • Clients receive IP address assignments from a rogue DHCP server.
    • The attacker provides incorrect DNS and default gateway information to clients.
    • The IP addresses assigned to legitimate clients are hijacked.
      Explanation:

      DCHP starvation attacks are launched by an attacker with the intent to create a DoS for DHCP clients. To accomplish this goal, the attacker uses a tool that sends many DHCPDISCOVER messages to lease the entire pool of available IP addresses, thus denying them to legitimate hosts.

  28. What are two types of attacks used on DNS open resolvers? (Choose two.)

    • resource utilization
    • ARP poisoning
    • amplification and reflection
    • fast flux
    • cushioning
      Explanation:

      Three types of attacks used on DNS open resolvers are as follows:DNS cache poisoning – attacker sends spoofed falsified information to redirect users from legitimate sites to malicious sites
      DNS amplification and reflection attacks – attacker sends an increased volume of attacks to mask the true source of the attack
      DNS resource utilization attacks – a denial of service (DoS) attack that consumes server resources

  29. What would be the target of an SQL injection attack?

    • database
    • DHCP
    • DNS
    • email
      Explanation:

      SQL is the language used to query a relational database. Cybercriminals use SQL injections to get information, create fake or malicious queries, or to breach the database in some other way.

  30. Which two options are security best practices that help mitigate BYOD risks? (Choose two.)

    • Use wireless MAC address filtering.
    • Decrease the wireless antenna gain level.
    • Keep the device OS and software updated.
    • Only turn on Wi-Fi when using the wireless network.
    • Only allow devices that have been approved by the corporate IT team.
    • Use paint that reflects wireless signals and glass that prevents the signals from going outside the building.
      Explanation:

      Many companies now support employees and visitors attaching and using wireless devices that connect to and use the corporate wireless network. This practice is known as a bring-your-own-device policy or BYOD. Commonly, BYOD security practices are included in the security policy. Some best practices that mitigate BYOD risks include the following:Use unique passwords for each device and account.
      Turn off Wi-Fi and Bluetooth connectivity when not being used. Only connect to trusted networks.
      Keep the device OS and other software updated.
      Backup any data stored on the device.
      Subscribe to a device locator service with a remote wipe feature.
      Provide antivirus software for approved BYODs.
      Use Mobile Device Management (MDM) software that allows IT teams to track the device and implement security settings and software controls.

  31. A user successfully logs in to a corporate network via a VPN connection. Which part of the AAA process records that a certain user performed a specific operation at a particular date and time?

      This question refers to AAA authentication, authorization, and accountability.

  33. In threat intelligence communications, which sharing standard is a specification for an application layer protocol that allows communication of cyberthreat intelligence over HTTPS?

    • Structured threat information expression (STIX)
    • Trusted automated exchange of indicator information (TAXII)
    • Common vulnerabilities and exposures (CVE)
    • Automated indicator sharing (AIS)
      Explanation:

      The two common threat intelligence sharing standards are as follows:

      • Structured Threat Information Expression (STIX) – This is a set of specifications for exchanging cyberthreat information between organizations. The Cyber Observable Expression (CybOX) standard has been incorporated into STIX.
      • Trusted Automated Exchange of Indicator Information (TAXII) – This is the specification for an application layer protocol that allows the communication of CTI over HTTPS. TAXII is designed to support STIX.
  34. A network security specialist is tasked to implement a security measure that monitors the status of critical files in the data center and sends an immediate alert if any file is modified. Which aspect of secure communications is addressed by this security measure?

    • data integrity
    • nonrepudiation
    • data confidentiality
    • origin authentication
      Explanation:

      Secure communications consists of four elements:

      • Data confidentiality – guarantees that only authorized users can read the message
      • Data integrity – guarantees that the message was not altered
      • Origin authentication – guarantees that the message is not a forgery and does actually come from whom it states
      • Data nonrepudiation – guarantees that the sender cannot repudiate, or refute, the validity of a message sent
  35. Which two statements describe the use of asymmetric algorithms? (Choose two.)

    • If a public key is used to encrypt the data, a public key must be used to decrypt the data.
    • If a private key is used to encrypt the data, a private key must be used to decrypt the data.
    • If a public key is used to encrypt the data, a private key must be used to decrypt the data.
    • If a private key is used to encrypt the data, a public key must be used to decrypt the data.
    • Public and private keys may be used interchangeably.
      Explanation:

      Asymmetric algorithms use two keys: a public key and a private key. Both keys are capable of the encryption process, but the complementary matched key is required for decryption. If a public key encrypts the data, the matching private key decrypts the data. The opposite is also true. If a private key encrypts the data, the corresponding public key decrypts the data.

  36. What is the most common use of the Diffie-Helman algorithm in communications security?

    • to provide routing protocol authentication between routers
    • to create password hashes for secure authentication
    • to encrypt data for secure e-commerce communications
    • to secure the exchange of keys used to encrypt data
      Explanation:

      Diffie-Helman is not an encryption mechanism and is not typically used to encrypt data. Instead, it is a method to securely exchange the keys used to encrypt the data.

  37. A customer purchases an item from an e-commerce site. The e-commerce site must maintain proof that the data exchange took place between the site and the customer. Which feature of digital signatures is required?

    • authenticity of digitally signed data
    • integrity of digitally signed data
    • nonrepudiation of the transaction
    • confidentiality of the public key
      Explanation:

      Digital signatures provide three basic security services:Authenticity of digitally signed data – Digital signatures authenticate a source, proving that a certain party has seen and signed the data in question.
      Integrity of digitally signed data – Digital signatures guarantee that the data has not changed from the time it was signed.
      Nonrepudiation of the transaction – The recipient can take the data to a third party, and the third party accepts the digital signature as a proof that this data exchange did take place. The signing party cannot repudiate that it has signed the data.

  38. When a user visits an online store website that uses HTTPS, the user browser queries the CA for a CRL. What is the purpose of this query?

    • to negotiate the best encryption to use
    • to verify the validity of the digital certificate
    • to request the CA self-signed digital certificate
    • to check the length of key used for the digital certificate
      Explanation:

      A digital certificate must be revoked if it is invalid. CAs maintain a certificate revocation list (CRL), a list of revoked certificate serial numbers that have been invalidated. The user browser will query the CRL to verify the validity of a certificate.

  39. Which management system implements systems that track the location and configuration of networked devices and software across an enterprise?

    • risk management

    • iptables
    • nftables
    • TCP Wrapper
    • Windows Firewall
      Explanation:

      Windows Firewall uses a profile-based approach to configuring firewall functionality. It uses three profiles, Public, Private, and Domain, to define firewall functions.

  41. Which approach is intended to prevent exploits that target syslog?

    • Use syslog-ng.
    • Use a Linux-based server.
    • Use a VPN between a syslog client and the syslog server.
    • Create an ACL that permits only TCP traffic to the syslog server.
      Explanation:

      Hackers may try to block clients from sending data to the syslog server, manipulate or erase logged data, or manipulate the software used to transmit messages between the clients and the server. Syslog-ng is the next generation of syslog and it contains improvements to prevent some of the exploits.

  42. Which two technologies are primarily used on peer-to-peer networks? (Choose two.)

    • Bitcoin
    • BitTorrent
    • Darknet
    • Snort
    • Wireshark
      Explanation:

      Bitcoin is used to share a distributed database or ledger. BitTorrent is used for file sharing.

  43. How can statistical data be used to describe or predict network behavior?

    • by listing results of user web surfing activities
    • by displaying alert messages that are generated by Snort
    • by recording conversations between network endpoints
    • by comparing normal network behavior to current network behavior
      Explanation:

      Statistical data is created through the analysis of other forms of network data. Statistical characteristics of normal network behavior can be compared to current network traffic in an effort to detect anomalies. Conclusions resulting from analysis can be used to describe or predict network behavior.

  51. Which term is used for describing automated queries that are useful for adding efficiency to the cyberoperations workflow?

    • rootkit
    • cyber kill chain
    • chain of custody
    • playbook 
      Explanation:

      A playbook is an automated query that can add efficiency to the cyberoperations workflow.

  52. Which statement describes the Cyber Kill Chain?

    • It uses the OSI model to describe cyberattacks at each of the seven layers.
    • It identifies the steps that adversaries must complete to accomplish their goals.
    • It specifies common TCP/IP protocols used to fight against cyberattacks.
    • It is a set of metrics designed to create a way to describe security incidents in a structured and repeatable way.
      Explanation:

      The Cyber Kill Chain was developed to identify and prevent cyber intrusions by specifying what threat actors must complete to accomplish their goals.

  53. When dealing with security threats and using the Cyber Kill Chain model, which two approaches can an organization use to block a potential back door creation? (Choose two.)

    • Conduct damage assessment.
    • Establish an incident response playbook.
    • Consolidate the number of Internet points of presence.
    • Audit endpoints to discover abnormal file creations.
    • Use HIPS to alert or place a block on common installation paths.
      Explanation:

      In the installation phase of the Cyber Kill Chain, the threat actor establishes a back door into the system to allow for continued access to the target. Among other measures, using HIPS to alert or block on common installation paths and auditing endpoints to discover abnormal file creations can help block a potential back door creation.

  54. Which schema or model allows security professionals to enter data about a particular incident, such as victim demographics, incident description, discovery method and response, and impact assessment, and share that data with the security community anonymously?

    • CSIRT
    • Cyber Kill Chain
    • Diamond
    • VERIS
      Explanation:

      Vocabulary for Event Recording and Incident Sharing (VERIS) is a set of metrics designed to create a way to describe security incidents in a structured or repeatable way. A Computer Security Incident response Team (CSIRT) is an internal organizational group that provides services and functions to secure assets. Cyber Kill Chain contains seven steps which help analysts understand the techniques, tools, and procedures of threat actors. The Diamond Model of intrusion has four parts that represent a security incident.

  55. What is the responsibility of the IT support group when handling a security incident?

    • Perform disciplinary measures if an incident is caused by an employee.
    • Coordinate the incident response with other stakeholders and minimize the damage of the incident.
    • Perform actions to minimize the effectiveness of the attack and preserve evidence.
    • Review the incident policies, plans, and procedures for local or federal guideline violations.
      Explanation:

      IT support best understands the technology used in the organization and can perform the correct actions to minimize the effectiveness of the attack and preserve evidence.
