CCNA Security 640-553 IINS Real Exam Questions
The 640-553 Implementing Cisco IOS Network Security (IINS) exam is associated with the CCNA Security certification. This exam tests a candidate’s knowledge of securing Cisco routers and switches and their associated networks. It leads to validated skills for installation, troubleshooting and monitoring of network devices to maintain integrity, confidentiality and availability of data and devices and develops competency in the technologies that Cisco uses in its security infrastructure.
1: Which consideration is important when implementing Syslogging in your network?
A.Use SSH to access your Syslog information.
B.Enable the highest level of Syslogging available to ensure you log all possible event messages.
C.Log all messages to the system buffer so that they can be displayed when accessing the router.
D.Syncronize clocks on the network with a protocol such as Network Time Protocol.
Correct Answers: D
2: Which statement is true when you have generated RSA keys on your Cisco router to prepare for secure device management?
A.You must then zeroize the keys to reset secure shell before configuring other parameters.
B.The SSH protocol is automatically enabled.
C.You must then specify the general-purpose key size used for authentication with the crypto key generate rsa general-keys modulus command.
D.All vty ports are automatically enabled for SSH to provide secure management.
Correct Answers: B
3: What does level 5 in the following enable secret global configuration mode command indicate?
router#enable secret level 5 password
A.The enable secret password is hashed using MD5.
B.The enable secret password is hashed using SHA.
C.The enable secret password is encrypted using Cisco proprietary level 5 encryption.
D.Set the enable secret command to privilege level 5.
E.The enable secret password is for accessing exec privilege level 5.
Correct Answers: E
4: Which of these correctly matches the CLI command(s) to the equivalent SDM wizard that performs similar configuration functions?
A.Cisco Common Classification Policy Language configuration commands and the SDM Site-to-Site VPN wizard
B.auto secure exec command and the SDM One-Step Lockdown wizard
C.setup exec command and the SDM Security Audit wizard
D.class-maps, policy-maps, and service-policy configuration commands and the SDM IPS wizard
E.aaa configuration commands and the SDM Basic Firewall wizard
Correct Answers: B
5: What is the key difference between host-based and network-based intrusion prevention?
A.Network-based IPS is better suited for inspection of SSL and TLS encrypted data flows.
B.Network-based IPS provides better protection against OS kernel-level attacks against hosts and servers.
C.Network-based IPS can provide protection to desktops and servers without the need of installing specialized software on the end hosts and servers.
D.Host-based IPS can work in promiscuous mode or inline mode.
E.Host-based IPS is more scalable then network-based IPS.
F.Host-based IPS deployment requires less planning than network-based IPS.
Correct Answers: C
6: You suspect an attacker in your network has configured a rogue layer 2 device to intercept traffic from multiple VLANS, thereby allowing the attacker to capture potentially sensitive data. Which two methods will help to mitigate this type of activity? (Choose two.)
A.Turn off all trunk ports and manually configure each VLAN as required on each port
B.Disable DTP on ports that require trunking
C.Secure the native VLAN, VLAN 1 with encryption
D.Set the native VLAN on the trunk ports to an unused VLAN
E.Place unused active ports in an unused VLAN
Correct Answers: B D
7: Which three statements about SSL-based VPNs are true? (Choose three.)
A.Asymmetric algorithms are used for authentication and key exchange.
B.SSL VPNs and IPsec VPNs cannot be configured concurrently on the same router.
C.Symmetric algorithms are used for bulk encryption.
D.The authentication process uses hashing technologies.
E.SSL VPNs require special-purpose client software to be installed on the client machine.
F.You can also use the application programming interface to extensively modify the SSL client software for use in special applications.
Correct Answers: A C D
8: When configuring AAA login authentication on Cisco routers, which two authentication methods should be used as the final method to ensure that the administrator can still log in to the router in case the external AAA server fails? (Choose two.)
Correct Answers: C E
9: What is a result of securing the Cisco IOS image using the Cisco IOS image resilience feature?
A.The show version command will not show the Cisco IOS image file location.
B.The Cisco IOS image file will not be visible in the output from the show flash command.
C.When the router boots up, the Cisco IOS image will be loaded from a secured FTP location.
D.The running Cisco IOS image will be encrypted and then automatically backed up to the NVRAM.
E.The running Cisco IOS image will be encrypted and then automatically backed up to a TFTP server.
Correct Answers: B
10: Which two protocols enable Cisco SDM to pull IPS alerts from a Cisco ISR router? (Choose two.)
