• RouterA(config)# login cake-for 30 attempts 10 within two

3. What is the purpose of the network security accounting function?

• to require users to testify who they are
• to determine which resources a user can access
• to keep track of the actions of a user
• to provide claiming and response questions

four. What blazon of assail may involve the employ of tools such as nslookup and fping?

• admission attack
• reconnaissance attack
• deprival of service attack
• worm attack

5. Lucifer each weakness with an example. (Not all options are used.)

6. Match the type of information security threat to the scenario. (Not all options are used.)

Explanation:
Afterwards an intruder gains access to a network, common network threats are as follows:

• Information theft
• Identity theft
• Data loss or manipulation
• Disruption of service

Peachy the password for a known username is a blazon of access set on.

seven. Which example of malicious code would exist classified as a Trojan horse?

• malware that was written to look like a video game
• malware that requires manual user intervention to spread between systems
• malware that attaches itself to a legitimate programme and spreads to other programs when launched
• malware that tin can automatically spread from ane organisation to another past exploiting a vulnerability in the target

eight. What is the difference between a virus and a worm?

• Viruses self-replicate but worms practice not.
• Worms cocky-replicate but viruses do non.
• Worms crave a host file just viruses practise not.
• Viruses hide in legitimate programs but worms do not.

Explanation: Worms are able to self-replicate and exploit vulnerabilities on computer networks without user participation.

9. Which attack involves a compromise of data that occurs between two end points?

• denial-of-service
• man-in-the-middle attack
• extraction of security parameters
• username enumeration

Explanation: Threat actors frequently endeavor to access devices over the cyberspace through communication protocols. Some of the about popular remote exploits are equally follows:

• Human being-In-the-middle attack (MITM) – The threat actor gets between devices in the system and intercepts all of the information existence transmitted. This information could but exist collected or modified for a specific purpose and delivered to its original destination.
• Eavesdropping assail – When devices are existence installed, the threat actor tin intercept data such equally security keys that are used past constrained devices to constitute communications in one case they are upwards and running.
• SQL injection (SQLi) – Threat actors uses a flaw in the Structured Query Language (SQL) application that allows them to have access to change the data or gain authoritative privileges.
• Routing assault – A threat player could either place a rogue routing device on the network or modify routing packets to manipulate routers to send all packets to the called destination of the threat actor. The threat actor could then drop specific packets, known every bit selective forwarding, or drop all packets, known as a sinkhole assail.

ten. Which type of assault involves an adversary attempting to gather information about a network to identify vulnerabilities?

• reconnaissance
• DoS
• lexicon
• man-in-the-middle

eleven. Match the description to the type of firewall filtering. (Not all options are used.)

12. What is the purpose of the network security authentication function?

• to require users to evidence who they are
• to determine which resource a user tin access
• to keep track of the deportment of a user
• to provide claiming and response questions

Explanation: Authentication, authorization, and accounting are network services collectively known as AAA. Authentication requires users to prove who they are. Authorization determines which resources the user can access. Accounting keeps track of the actions of the user.

13. Which firewall feature is used to ensure that packets coming into a network are legitimate responses to requests initiated from internal hosts?

• stateful packet inspection
• URL filtering
• awarding filtering
• packet filtering

14. When applied to a router, which control would aid mitigate brute-force password attacks against the router?

• exec-timeout thirty
• service password-encryption
• banner motd $Max failed logins = five$
• login block-for threescore attempts 5 within 60

Explanation: The login block-for command sets a limit on the maximum number of failed login attempts allowed inside a defined menstruation of time. If this limit is exceeded, no further logins are allowed for the specified period of time. This helps to mitigate brute-force password corking since it will significantly increase the amount of time required to cleft a password. The exec-timeout command specifies how long the session can be idle before the user is asunder. The service password-encryption control encrypts the passwords in the running configuration. The imprint motd command displays a message to users who are logging in to the device.

15. Identify the steps needed to configure a switch for SSH. The answer club does non affair. (Non all options are used.)

Explanation: The login and password cisco commands are used with Telnet switch configuration, not SSH configuration.

16. What characteristic of SSH makes it more secure than Telnet for a device management connection?

• confidentiality with IPsec
• stronger countersign requirement
• random i-time port connection
• login information and data encryption

Explanation: Secure Crush (SSH) is a protocol that provides a secure management connection to a remote device. SSH provides security past providing encryption for both authentication (username and password) and the transmitted data. Telnet is a protocol that uses unsecure plaintext transmission. SSH is assigned to TCP port 22 past default. Although this port tin can be changed in the SSH server configuration, the port is not dynamically changed. SSH does not utilize IPsec.

17. What is the advantage of using SSH over Telnet?

• SSH is easier to employ.
• SSH operates faster than Telnet.
• SSH provides secure communications to access hosts.
• SSH supports authentication for a connectedness asking.

Explanation: SSH provides a secure method for remote access to hosts by encrypting network traffic between the SSH client and remote hosts. Although both Telnet and SSH request authentication before a connection is established, Telnet does non back up encryption of login credentials.

18. What is the office of an IPS?

• detecting and blocking of attacks in real time
• connecting global threat information to Cisco network security devices
• authenticating and validating traffic
• filtering of nefarious websites

Explanation: An intrusion prevention system (IPS) provides real-time detection and blocking of attacks.

19. A user is redesigning a network for a small company and wants to ensure security at a reasonable cost. The user deploys a new application-enlightened firewall with intrusion detection capabilities on the Internet service provider connexion. The user installs a 2nd firewall to separate the company network from the public network. Additionally, the user installs an IPS on the internal network of the company. What approach is the user implementing?

• attack based
• risk based
• structured
• layered

Explanation: Using different defenses at various points of the network creates a layered approach.

20. What is an accurate clarification of redundancy?

• configuring a router with a consummate MAC address database to ensure that all frames tin can be forwarded to the correct destination
• configuring a switch with proper security to ensure that all traffic forwarded through an interface is filtered
• designing a network to utilise multiple virtual devices to ensure that all traffic uses the best path through the internetwork
• designing a network to utilise multiple paths betwixt switches to ensure in that location is no single point of failure

Caption: Redundancy attempts to remove any single indicate of failure in a network by using multiple physically cabled paths between switches in the network.

21. A network administrator is upgrading a pocket-sized concern network to requite high priority to real-time applications traffic. What ii types of network services is the network administrator trying to adjust? (Choose two.)

• vocalism
• video
• instant messaging
• FTP
• SNMP

22. What is the purpose of a small company using a protocol analyzer utility to capture network traffic on the network segments where the visitor is considering a network upgrade?

• to place the source and destination of local network traffic
• to capture the Internet connection bandwidth requirement
• to document and clarify network traffic requirements on each network segment
• to establish a baseline for security assay after the network is upgraded

Caption: An important prerequisite for considering network growth is to empathise the type and amount of traffic that is crossing the network equally well equally the current traffic flow. By using a protocol analyzer in each network segment, the network administrator can document and clarify the network traffic blueprint for each segment, which becomes the base in determining the needs and means of the network growth.

23. Refer to the exhibit. An administrator is testing connectivity to a remote device with the IP accost 10.1.i.ane. What does the output of this command signal?

• Connectivity to the remote device was successful.
• A router along the path did not have a route to the destination.
• A ping packet is being blocked by a security device forth the path.
• The connection timed out while waiting for a reply from the remote device.

Explanation: In the output of the ping command, an exclamation mark (!) indicates a response was successfully received, a menstruum (.) indicates that the connection timed out while waiting for a reply, and the letter of the alphabet "U" indicates that a router along the path did not accept a route to the destination and sent an ICMP destination unreachable bulletin back to the source.

24. Which method is used to send a ping message specifying the source address for the ping?

• Outcome the ping command from inside interface configuration mode.
• Issue the ping command without specifying a destination IP address.
• Consequence the ping command without extended commands.
• Result the ping control after shutting down un-needed interfaces.

Caption: By issuing the ping command without a destination IP address in privileged EXEC mode, the Cisco IOS enters extended ping style. This allows the user to implement extended commands which include source IP accost.​

25. A network engineer is analyzing reports from a recently performed network baseline. Which state of affairs would depict a possible latency result?

• a alter in the bandwidth according to the evidence interfaces output
• a next-hop timeout from a traceroute
• an increase in host-to-host ping response times
• a modify in the amount of RAM according to the show version output

Explanation: While analyzing historical reports an administrator can compare host-to-host timers from the ping command and draw possible latency bug.​

26. Which statement is true near Cisco IOS ping indicators?​

• '!' indicates that the ping was unsuccessful and that the device may have issues finding a DNS server.
• 'U' may indicate that a router along the path did non contain a road to the destination address and that the ping was unsuccessful.
• '.' indicates that the ping was successful but the response fourth dimension was longer than normal.
• A combination of '.' and '!' indicates that a router along the path did non accept a route to the destination accost and responded with an ICMP unreachable message.​

Explanation: The most common indicators of a ping issued from the Cisco IOS are "!", ".", and "U". The "!" indicates that the ping completed successfully, verifying connectivity at Layer 3. The "." may indicate that a connectivity trouble, routing problem, or device security event exists forth the path and that an ICMP destination unreachable bulletin was non provided. The "U" indicates that a router along the path may not have had a road to the destination address, and that it responded with an ICMP unreachable message.

27. A user reports a lack of network connectivity. The technician takes command of the user automobile and attempts to ping other computers on the network and these pings fail. The technician pings the default gateway and that also fails. What can exist determined for sure by the results of these tests?

• The NIC in the PC is bad.
• The TCP/IP protocol is not enabled.
• The router that is attached to the aforementioned network as the workstation is downward.
• Nothing tin can be determined for sure at this point.

Explanation: In networks today, a failed ping could mean that the other devices on the network are blocking pings. Farther investigation such every bit checking network connectivity from other devices on the same network is warranted.

28. A network technician issues the C:\> tracert -6 www.cisco.com command on a Windows PC. What is the purpose of the -6 command option?

• It forces the trace to use IPv6.
• Information technology limits the trace to merely six hops.
• It sets a 6 milliseconds timeout for each replay.
• It sends 6 probes within each TTL time catamenia.

29. Why would a network administrator employ the tracert utility?

• to make up one's mind the active TCP connections on a PC
• to cheque information about a DNS name in the DNS server
• to identify where a packet was lost or delayed on a network
• to display the IP accost, default gateway, and DNS server address for a PC

Explanation: The tracert utility is used to identify the path a package takes from source to destination. Tracert is commonly used when packets are dropped or not reaching a specific destination.

30. A ping fails when performed from router R1 to directly connected router R2. The network administrator then gain to issue the show cdp neighbors command. Why would the network administrator event this control if the ping failed betwixt the two routers?

• The network administrator suspects a virus considering the ping command did not work.
• The network ambassador wants to verify Layer ii connectivity.
• The network administrator wants to verify the IP address configured on router R2.
• The network administrator wants to determine if connectivity can be established from a non-directly continued network.

Explanation: Theshow cdp neighborscommand can be used to prove that Layer i and Layer 2 connectivity exists between 2 Cisco devices. For example, if two devices have duplicate IP addresses, a ping between the devices will fail, merely the output ofshow cdp neighbors will be successful. Theshow cdp neighbors detailcould exist used to verify the IP accost of the direct continued device in case the same IP address is assigned to the two routers.

31. A network engineer is troubleshooting connectivity bug among interconnected Cisco routers and switches. Which command should the engineer use to discover the IP address information, host name, and IOS version of neighboring network devices?

• show version
• prove ip road
• show interfaces
• show cdp neighbors item

Explanation: Theshow cdp neighbors particularcontrol reveals much information nigh neighboring Cisco devices, including the IP address, the capabilities, host name, and IOS version. Theshow interfaces and show version commands display data about the local device.

• Change system passwords every 30 days.
• Ensure that all systems accept the most current virus definitions.
• Ensure that AAA is configured in the network.
• Download security updates from the operating system vendor and patch all vulnerable systems.

Caption: Because worms accept advantage of vulnerabilities in the system itself, the about constructive way to mitigate worm attacks is to download security updates from the operating arrangement vendor and patch all vulnerable systems.

45. Which statement describes the ping and tracert commands?

• Tracert shows each hop, while ping shows a destination reply only.
• Tracert uses IP addresses; ping does not.
• Both ping and tracert tin show results in a graphical brandish.
• Ping shows whether the manual is successful; tracert does not.

Explanation: Theping utility tests end-to-end connectivity between the 2 hosts. Withal, if the message does not reach the destination, in that location is no way to determine where the trouble is located. On the other manus, thetraceroute utility (tracert in Windows) traces the route a message takes from its source to the destination.Traceroute displays each hop along the way and the time it takes for the message to get to that network and dorsum.

46. A technician is to document the current configurations of all network devices in a higher, including those in off-site buildings. Which protocol would exist best to use to securely access the network devices?

• FTP
• HTTP
• SSH
• Telnet
