A network administrator configures a named ACL on the router. ), Match the security term to the appropriate description, 122. The default action of shutdown is recommended because the restrict option might fail if an attack is underway. 23. It allows for the transmission of keys directly across a network. After spending countless hours in training, receiving many industry related certifications, and bringing her son Chris in as the director of operations following his graduation from UC Santa Barbara, straughn Communications is equipped with the Therefore the correct answer is D. 13) Which one of the following usually used in the process of Wi-Fi-hacking? Explanation: Port security is the most effective method for preventing CAM table overflow attacks. In short, we can say that its primary work is to restrict or control the assignment of rights to the employees. Without Wi-Fi security, a networking device such as a wireless access point or a router can be accessed by anyone using a computer or mobile device within range of the router's wireless signal. Explanation: Cryptanalysis is the practice and study of determining the meaning of encrypted information (cracking the code), without access to the shared secret key. For this reason, there are many network security management tools and applications in use today that address individual threats and exploits and also regulatory non-compliance. (Choose two.). Use VLAN 1 as the native VLAN on trunk ports. Refer to the exhibit. Both devices use an implicit deny, top down sequential processing, and named or numbered ACLs. Which two statements describe the effect of the access control list wildcard mask 0.0.0.15? 42) Which of the following type of text is transformed with the help of a cipher algorithm? Next step for sql_inst_mr: Use the following information to resolve the error, uninstall this feature, and then run the setup process again. 36) Suppose an employee demands the root access to a UNIX system, where you are the administrator; that right or access should not be given to the employee unless that employee has work that requires certain rights, privileges. A virus focuses on gaining privileged access to a device, whereas a worm does not. Explanation: Snort IPS mode can perform all the IDS actions plus the following: Drop Block and log the packet. Reject Block the packet, log it, and then send a TCP reset if the protocol is TCP or an ICMP port unreachable message if the protocol is UDP. Sdrop Block the packet but do not log it. These vulnerabilities can exist in a broad number of areas, including devices, data, applications, users and locations. B. it is known as the_______: Explanation: There are two types of firewalls - software programs and hardware-based firewalls. Activate the virtual services. Step 5. WebEstablished in 1983. When a computer sends data over the Internet, the data is grouped into a single packet. 22. Protocol uses Telnet, HTTP. Frames from PC1 will be forwarded to its destination, but a log entry will not be created. Port security has been configured on the Fa 0/12 interface of switch S1. It prevents traffic on a LAN from being disrupted by a broadcast storm. )if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'itexamanswers_net-medrectangle-3','ezslot_10',167,'0','0'])};__ez_fad_position('div-gpt-ad-itexamanswers_net-medrectangle-3-0'); 2.

Explanation: An application gateway firewall, also called a proxy firewall, filters information at Layers 3, 4, 5, and 7 of the OSI model. D. Circuit Handshake authentication protocol. 50 How do modern cryptographers defend against brute-force attacks? Explanation: NAT can be deployed on an ASA using one of these methods:inside NAT when a host from a higher-security interface has traffic destined for a lower-security interface and the ASA translates the internal host address to a global addressoutside NAT when traffic from a lower-security interface destined for a host on the higher-security interface is translatedbidirectional NAT when both inside NAT and outside NAT are used togetherBecause the nat command is applied so that the inside interface is mapped to the outside interface, the NAT type is inside. MD5 and SHA-1 can be used to ensure data integrity. DH (Diffie-Hellman) is an algorithm used for key exchange. Explanation: A CLI view has no command hierarchy, and therefore, no higher or lower views. Second, generate a set of RSA keys to be used for encrypting and decrypting the traffic. PC1 has a different MAC address and when attached will cause the port to shut down (the default action), a log message to be automatically created, and the violation counter to increment. If a private key encrypts the data, the corresponding public key decrypts the data. Place the steps for configuring zone-based policy (ZPF) firewalls in order from first to last. Place extended ACLs close to the source IP address of the traffic. What function is performed by the class maps configuration object in the Cisco modular policy framework?

This set of following multiple-choice questions and answers focuses on "Cyber Security". Explanation: Trojans are a type of malware that will perform any types of actions for those they are design or programmed. Which rule action will cause Snort IPS to block and log a packet? What are two differences between stateful and packet filtering firewalls? The traffic is selectively permitted and inspected. The tunnel configuration was established and can be tested with extended pings. (Choose two.). Explanation: Stateful firewalls cannot prevent application layer attacks because they do not examine the actual contents of the HTTP connection. 64. According to the command output, which three statements are true about the DHCP options entered on the ASA? Explanation: The "Security through obscurity" is an approach which just opposite to the Open Design principle. If a public key encrypts the data, the matching private key decrypts the data. Hacktivists use their hacking as a form of political or social protest, and vulnerability brokers hack to uncover weaknesses and report them to vendors. supplicantThe interface acts only as a supplicant and does not respond to messages that are meant for an authenticator. 26. ACLs can also be used to identify traffic that requires NAT and QoS services. Which of the following are objectives of Malware? An IDS is deployed in promiscuous mode. 9. Cybercriminals are increasingly targeting mobile devices and apps. To indicate the CLI EXEC mode, ASA uses the % symbol whereas a router uses the # symbol. Gain unified segmentation of workloads: a single pane of glass from the workload to the network and cloud, supporting all workload types without limitations. Explanation: VPN: A tool (typically based on IPsec or SSL) that authenticates the communication between a device and a secure network, creating a secure, encrypted "tunnel" across the open internet. A rootkit is a self-replicating program that masks itself as a useful program but is actually a type of malware. ), 46 What are the three components of an STP bridge ID? What job would the student be doing as a cryptanalyst? These types of firewalls filter each and every data packet coming from the outside environment such as network; internet so that any kind of virus would not be able to enter in the user's system. C. Limiting drinking to one or fewer drinks per hour Traffic that is originating from the public network is usually permitted with little or no restriction when traveling to the DMZ network. Refer to the exhibit. Explanation: When the numbers of users on a network get increased and exceed the network's limit, therefore the performance is one of the factors of the network that is hugely impacted by it. 41) Which of the following statements is true about the VPN in Network security? It includes coverage of advance exploits by using the research work of the Cisco Talos security experts. Both use Cisco Talos to provide coverage in advance of exploits. It is always held once a year in Las Vegas, Nevada, where hackers of all types (such as black hats, gray hats, and white hat hackers), government agents as well as security professionals from around the world attend the conference attends this meeting. 89. In an attempt to prevent network attacks, cyber analysts share unique identifiable attributes of known attacks with colleagues. (Choose two.) Prevent sensitive information from being lost or stolen. Use dimensional analysis to change: HMAC uses protocols such as SSL or TLS to provide session layer confidentiality. A security policy requiring passwords to be changed in a predefined interval further defend against the brute-force attacks. Alternating non-alcohol drinks and alcohol drinks Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner. Forcepoint offers a suite of network security solutions that centralize and simplify what are often complex processes and ensure robust network security is in place across your enterprise.

HMAC uses a secret key as input to the hash function, adding authentication to integrity assurance. Commands cannot be added directly to a superview but rather must be added to a CLI view and the CLI view added to the superview. To detect abnormal network behavior, you must know what normal behavior looks like. Otherwise, a thief could retrieve discarded reports and gain valuable information. B. 5. Click (Choose three.). An IDS needs to be deployed together with a firewall device, whereas an IPS can replace a firewall. Explanation: Phreaking is considered as one of the oldest phone hacking techniques used by hackers to make free calls. Explanation: Tripwire This tool assesses and validates IT configurations against internal policies, compliance standards, and security best practices. Explanation: Using an intrusion prevention system (IPS) and firewall can limit the information that can be discovered with a port scanner. Two popular algorithms used to ensure that data is not intercepted and modified (data integrity and authenticity) are MD5 and SHA. Threat defense includes a firewall and intrusion prevention system (IPS). What is the primary security concern with wireless connections? ***A network security policy is a document that describes the rules governing access to a company's information resources Which of the following 14.

Which two types of hackers are typically classified as grey hat hackers? Explanation: Among the following-given options, the Cloud Scan is one, and only that is not a type of scanning. Every organization that wants to deliver the services that customers and employees demand must protect its network. (Choose three.). 124. 106. Create a superview using the parser view view-name command. Explanation: There are several benefits of a ZPF: It is not dependent on ACLs. The router security posture is to block unless explicitly allowed. Policies are easy to read and troubleshoot with C3PL. One policy affects any given traffic, instead of needing multiple ACLs and inspection actions. A network administrator configures AAA authentication on R1. Multiple inspection actions are used with ZPF. 25) Hackers usually used the computer virus for ______ purpose. Traffic from the Internet can access both the DMZ and the LAN. In contrast, asymmetric encryption algorithms use a pair of keys, one for encryption and another for decryption. Secure IPS appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection. Cisco IOS ACLs are processed sequentially from the top down and Cisco ASA ACLs are not processed sequentially. Refer to the exhibit. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats. 109. Install the OVA file. Step 3. What are two additional uses of ACLs? verified attack traffic is generating an alarmTrue positive, normal user traffic is not generating an alarmTrue negative, attack traffic is not generating an alarmFalse negative, normal user traffic is generating an alarmFalse positive. 5 or more drinks on an occasion, 3 or more times during a two-week period for males What is the function of a hub-and-spoke WAN topology? D. All of the above, Which choice is a unit of speed? They typically cause damages to the systems by consuming the bandwidths and overloading the servers. Which protocol would be best to use to securely access the network devices? The public zone would include the interfaces that connect to an external (outside the business) interface. 62. What action should the administrator take first in terms of the security policy? Depending on the perspective one possesses, state-sponsored hackers are either white hat or black hat operators. (Choose two.). AES and 3DES are two encryption algorithms. Ethernet is a transport layer protocol. Thebest antimalware programsnot only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage. 101. Upon completion of a network security course, a student decides to pursue a career in cryptanalysis. 48. 4 or more drinks on an occasion, 3 or more times during a two-week period for females An email security application blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data. Use the login local command for authenticating user access. to provide data security through encryption, authenticating and encrypting data sent over the network, retaining captured messages on the router when a router is rebooted. 5. (Choose two.). Network security combines multiple layers of defenses at the edge and in the network. A. malicious hardware B. malicious software C. Both A and B D. None of the above An IPS cannot replace other security devices, such as firewalls, because they perform different tasks. Explanation: The term "TCP/IP" stood for Transmission Control Protocol/ internet protocol and was developed by the US government in the early days of the internet. 35) Which of the following principle of cyber security restricts how privileges are initiated whenever any object or subject is created? Explanation: Access control refers to the security features. If a public key is used to encrypt the data, a public key must be used to decrypt the data. 33) Which of the following is considered as the world's first antivirus program? Which three objectives must the BYOD security policy address? If AAA is already enabled, which three CLI steps are required to configure a router with a specific view? Sometimes firewall also refers to the first line of defense against viruses, unauthorized access, malicious software etc. ), 12. A firewall is a network security device that monitors incoming and Web41) Which of the following statements is true about the VPN in Network security? The ACL has not been applied to an interface. (Choose two. B. client_hello 30) In the computer networks, the encryption techniques are primarily used for improving the ________. There is a mismatch between the transform sets. Immediately suspend the network privileges of the user. so that the switch stops forwarding traffic, so that legitimate hosts cannot obtain a MAC address, so that the attacker can execute arbitrary code on the switch. 138. The code was encrypted with both a private and public key. What function is performed by the class maps configuration object in the Cisco modular policy framework? It is a kind of cyber attack in which one tries to make a machine (or targeted application, website etc.) RADIUS hides passwords during transmission and does not encrypt the complete packet. Authorization is concerned with allowing and disallowing authenticated users access to certain areas and programs on the network. 95. Security features that control that can access resources in the OS. All other traffic is allowed. The first 28 bits of a supplied IP address will be matched. 102. A virtual private network encrypts the connection from an endpoint to a network, often over the internet. Explanation: The answer is UserID. 54. Which conclusion can be made from the show crypto map command output that is shown on R1? A recently created ACL is not working as expected.
