  1. What is an objective of a state-sponsored attack?

to gain financial prosperity

to sell operating system vulnerabilities to other hackers

to gain attention

to right a perceived wrong

 

  1. What role does the Security Intelligence Operations (SIO) play in the Cisco SecureX architecture?

identifying and stopping malicious traffic

authenticating users

enforcing policy

identifying applications

 

  1. What worm mitigation phase involves actively disinfecting infected systems?

Treatment

containment

inoculation

quarantine

 

  1. How is a smurf attack conducted?

by sending a large number of packets to overflow the allocated buffer memory of the target device

by sending a large number of ICMP requests to directed broadcast addresses from a spoofed source address on the same network

by sending a large number of TCP SYN packets to a target device from a spoofed source address

by sending an echo requesting an IP packet larger than the maximum packet size of 65,535 bytes

 

  1. What is a characteristic of a Trojan horse as it relates to network security?

Malware is contained in a seemingly legitimate executable program.

Extreme quantities of data are sent to a particular network device interface.

An electronic dictionary is used to obtain a password to be used to infiltrate a key network device.

Too much information is destined for a particular memory block, causing additional memory areas to be affected

 

  1. What is the first step in the risk management process specified by the ISO/IEC?

Create a security policy

Conduct a risk assessment.

Inventory and classify IT assets.

Create a security governance model

 

  1. What is the significant characteristic of worm malware?

A worm can execute independently of the host system.

A worm must be triggered by an event on the host system.

Worm malware disguises itself as legitimate software.

Once installed on a host system, a worm does not replicate itself

 

  1. Which condition describes the potential threat created by Instant On in a data center?

When the primary firewall in the data center crashes

when an attacker hijacks a VM hypervisor and then launches attacks against other devices in the data center

when the primary IPS appliance is malfunctioning

when a VM that may have outdated security policies is brought online after a long period of inactivity

 

  1. What are the three core components of the Cisco Secure Data Center solution? (Choose three.)

mesh network

secure segmentation

visibility

threat defense

servers

Infrastructure

 

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

trust exploitation

denial of service

reconnaissance

port redirection

 

  1. Which two statements describe access attacks? (Choose two.)

Trust exploitation attacks often involve the use of a laptop to act as a rogue access point to capture and copy all network traffic in a public location, such as a wireless hotspot

To detect listening services, port scanning attacks scan a range of TCP or UDP port numbers on a host

Buffer overflow attacks write data beyond the allocated buffer memory to overwrite valid data or to exploit systems to execute malicious code.

Password attacks can be implemented by the use of brute-force attack methods, Trojan horses, or packet sniffers.

Port redirection attacks use a network adapter card in promiscuous mode to capture all network packets that are sent across a LAN

 

  1. What is a ping sweep?

a scanning technique that examines a range of TCP or UDP port numbers on a host to detect listening services.

a software application that enables the capture of all network packets that are sent across a LAN.

a query and response protocol that identifies information about a domain, including the addresses that are assigned to that domain.

a network scanning technique that indicates the live hosts in a range of IP addresses

 

  1. As a dedicated network security tool, an intrusion Prevention system can provide detection and blocking of attacks in real time.

  1. 9. What functional area of the Cisco Network Foundation Protection framework is responsible for device-generated packets required for network operation, such as ARP message exchanges and routing advertisements?
    Ans: Control Plane

    1. One of the first network security tools was the intrusion detection system (IDS). IDS and now the newer intrusion prevention system (IPS), provide real-time detection of certain types of attacks. Unlike an IDS, an IPS can also automatically block the attack in real-time.

  2. 24
    Fill in the blank.
    As a dedicated network security tool, an intrusion
    protection
    system can provide detection and blocking of attacks in real time.
    Correct Answer: prevention

  3. As a dedicated network security tool, an intrusion ____ system can provide detection and blocking of attacks in real time.
    Correct Answer: prevention

  4. Question 24 :

    As a dedicated network security tool, an intrusion ___________ system can provide detection and blocking of attacks in real time.

    Ans: PREVENTION

  5. Hello Guys, I´m about to write the CCNA Security 210-260 exams soon
    Can someone please recommend a good resource like Exam questions , VCE´s or Dumps.
    i reall need help right now.
    Thank´s in advance for your help.

  6. La pregunta y respuesta #24 es correcta, aca les dejo la informacion;

    One of the first network security tools was the intrusion detection system (IDS). IDS and now the newer intrusion prevention system (IPS), provide real-time detection of certain types of attacks. Unlike an IDS, an IPS can also automatically block the attack in real-time.

    1. Thanks sir for your confirmation. if you can identify which answers is wrong or any new questions it will be great helps to all of us.

  7. What commonly motivates cybercriminals to attack networks as compared to hactivists or state-sponsored hackers?

    Ans: Financial gain

    1. Hi, thanks for your feedback. But the question and answer already listed at number 5. The “hactivists” spell is wrong might be the reason you can’t find using search. TQ
