CCNA Security Chapter 1

  1. 1. Below you will find the assessment items as presented on the exam as well as the scoring rules associated with the item.Cisco Networking Academy content is copyrighted and the unauthorized posting, distribution or sharing of this exam content is prohibited.1 What is a ping sweep?A ping sweep is a network scanning technique that indicates the live hosts in a range of IP addresses.A ping sweep is a software application that enables the capture of all network packets sent across a LAN.A ping sweep is a scanning technique that examines a range of TCP or UDP port numbers on a host to detect listening services.A ping sweep is a query and response protocol that identifies information about a domain, including the addresses assigned to that domain.Observable Description Max Value1correctness ofresponse2 points for Option 10 points for any other option2This item references content from the following areas:CCNA Security: Implementing Network Security 1.3.1 Reconnaissance Attacks2 Which access attack method involves a software program attempting to discover a system password by using an electronic dictionary?buffer overflow attackport redirection attackDenial of Service attackbrute-force attackIP spoofing attackpacket sniffer attackObservable Description Max Value1correctness ofresponse2 points for Option 40 points for any other option2This item references content from the following areas:CCNA Security: Implementing Network Security 1.3.2 Access Attacks3 How is a Smurf attack conducted?by sending a large number of packets, overflowing the allocated buffer memory of the target deviceby sending an echo request in an IP packet larger than the maximum packet size of 65,535 bytesby sending a large number of ICMP requests to directed broadcast addresses from a spoofed source address on the same networkby sending a large number of TCP SYN packets to a target device from a spoofed source addressObservable Description Max Value1correctness ofresponse2 points for Option 30 points for any other option2This item references content from the following areas:CCNA Security: Implementing Network Security 1.3.3 Denial of Service Attacks4 A port scan is classified as what type of attack?access attack

(Choose three.)The containment phase requires the use of incoming and outgoing ACLs on routers and firewalls.The containment phase tracks down and identifies the infected machines within the contained areas.The inoculation phase disconnects, blocks, or removes infected machines.The inoculation phase patches uninfected systems with the appropriate vendor patch for the vulnerability.The quarantine phase terminates the worm process, removes modified files or system settings, and patches the vulnerability the worm used to exploit the system.The treatment phase disinfects actively infected systems.Observable Description Max Value1correctness ofresponseOption 1, Option 4, and Option 6 are correct.1 point for each correct option.0 points if more options are selected than required.3This item references content from the following areas:CCNA Security: Implementing Network Security 1.2.4 Mitigating Viruses, Worms, and Trojan Horses10 Which phase of worm mitigation requires compartmentalization and segmentation of the network to slow down or stop the worm and prevent currently infected hosts from targeting and infecting osystems?containment phaseinoculation phasequarantine phasetreatment phaseObservable Description Max Value1correctness ofresponse2 points for Option 10 points for any other option2
  4. 4. This item references content from the following areas:CCNA Security: Implementing Network Security 1.2.4 Mitigating Viruses, Worms, and Trojan Horses11 What is a characteristic of a Trojan Horse?A Trojan Horse can be carried in a virus or worm.A proxy Trojan Horse opens port 21 on the target system.An FTP Trojan Horse stops anti-virus programs or firewalls from functioning.A Trojan Horse can be hard to detect because it closes when the application that launched it closes.Observable Description Max Value1correctness ofresponse2 points for Option 10 points for any other option2This item references content from the following areas:CCNA Security: Implementing Network Security 1.2.3 Trojan Horses12 Which two statements are characteristics of a virus? (Choose two.)A virus typically requires end-user activation.A virus has an enabling vulnerability, a propagation mechanism, and a payload.A virus replicates itself by independently exploiting vulnerabilities in networks.A virus provides the attacker with sensitive data, such as passwords.A virus can be dormant and then activate at a specific time or date.Observable Description Max Value1correctness ofresponseOption 1 and Option 5 are correct.1 point for each correct option.0 points if more options are selected than required.2This item references content from the following areas:CCNA Security: Implementing Network Security 1.2.4 Mitigating Viruses, Worms, and Trojan Horses13 Which two are characteristics of DoS attacks? (Choose two.)They always precede access attacks.They attempt to compromise the availability of a network, host, or application.They are difficult to conduct and are initiated only by very skilled attackers.They are commonly launched with a tool called L0phtCrack.Examples include smurf attacks and ping of death attacks.Observable Description Max Value1correctness ofresponseOption 2 and Option 5 are correct.1 point for each correct option.0 points if more options are selected than required.2This item references content from the following areas:CCNA Security: Implementing Network Security 1.3.3 Denial of Service Attacks
  5. 5. 14 Which two statements describe access attacks? (Choose two.)Port redirection attacks use a network adapter card in promiscuous mode to capture all network packets that are sent across a LAN.Password attacks can be implemented using brute-force attack methods, Trojan Horses, or packet sniffers.Buffer overflow attacks write data beyond the allocated buffer memory to overwrite valid data or exploit systems to execute malicious code.Port scanning attacks scan a range of TCP or UDP port numbers on a host to detect listening services.Trust exploitation attacks can use a laptop acting as a rogue access point to capture and copy all network traffic in a public location on a wireless hotspot.Observable Description Max Value1correctness ofresponseOption 2 and Option 3 are correct.1 point for each correct option.0 points if more options are selected than required.2This item references content from the following areas:CCNA Security: Implementing Network Security 1.3.2 Access Attacks15 A disgruntled employee is using Wireshark to discover administrative Telnet usernames and passwords.
