c cc 1. What will be disabled as a result of the command ? aaa new-model global configuration command. change to the configuration register. password encryption service. ability to access ROMmon. || x. What occurs after RSA keys are generated on a Cisco router to prepare for secure device management? All vty ports are automatically configured for SSH to provide secure management. The general-purpose key size must be specified for authentication with the crypto key generate rsa general-keys mo command. The keys must be zeroized to reset secure shell before configuring other parameters. The generated keys can be used by SSH. | 3. Which action best describe a MAC address spoofing attack? altering the MAC address of an attacking host to match that of a legitimate host. bombarding a switch with fake source MAC addresses. forcing the election of a rogue root bridge flooding the LAN with excessive traffic | 4. What functionality is provided by Cisco SPAN in a switched network? It mitigates MAC address overflow attacks. It mirrors traffic that passes through a switch port or VLAN to another port for traffic analysis. It protects the switched network from receiving BPDUs on ports that should not be receiving them. It inspects voice protocols to ensure that SIP, SCCP, H.3x3, and MGCP requests conform to voice standards. It copies traffic that passes through a switch interface and sends the data directly to a syslog or SNMP server for analysis. | 5. What precaution should be considered when the command has been issued on an IOS device? The passwords in the configuration files are in clear text. IOS recovery requires a new system flash with the IOS image. When the password is lost, access to the device will be terminated. The device must use simple password authentication and cannot have user authentication. | . A network technician is configuring SNMPv3 and has set a security level of . What is the effect of this setting? Authenticates a packet using the SHA algorithm only. Authenticates a packet by a string match of the username or community string. Authenticates a packet by using either the HMAC with MD5 method or the SHA method. Authenticates a packet by using either the HMAC MD5 or HMAC SHA algorithms and encrypts the packet using either the DES, 3DES or AES algorithms. |

Which two statements describe appropriate general guidelines for configuring and applying ACLs? (Choose two) Multiple ACLs per protocol and per direction can be applied to an interface. If an ACL contains no permit statements, all traffic is denied by default. The most specific ACL statements should be entered first because of the top-down sequential nature of ACLs. Standard ACLs are placed closest to the source, whereas Extended ACLs are placed closest to the destination. If a single ACL is to be applied to multiple interfaces, it must be configured with a unique number for each interface. | x0. Which three statements are characteristics of the IPsec protocol? (Choose three) IPsec is a framework of open standards. IPsec is implemented at Layer 4 of the OSI model. IPsec ensures data integrity by using a hash algorithm. IPsec uses digital certificates to guarantee confidentiality IPsec is bound to specific encryption algorithms, such as 3DES and AES. IPsec authenticates users and devices that communicate independently. | x1. Which three additional precautions should be taken when remote access is required in addition to local access of networking devices? (Choose three) A legal notice should not be displayed when access is obtained. All activity to the specified ports that are required for access should be unrestricted. All configuration activities should required the use of SSH or HTTPS. All administrative traffic should be dedicated to the management network. The number of failed login attempts should not be limited, but the time between attempts should. Packet filtering should be required so that only identified administration hosts and protocols can gain access. | xx. Which statement describes a factor to be considered when configuring a zone-based policy firewall? An interface can belong to multiple zones. The router always filters the traffic between interfaces in the same zone. The CBAC ip inspect command can coexist with ZPF as long as it is used on interfaces that are in the same security zones. A zone must be configured with the zone security global command before it can be used in the zone-member security command. | x3. What is a result of securing the Cisco IOS image using the Cisco IOS Resilient Configuration feature? The Cisco IOS image file is not visible in the output of the l command.

The violation mode for the port is set to restrict. The MAC address table is cleared, and the new MAC address is entered into the table. The port remains enabled, but the bandwidth is throttled until the old MAC addresses are aged out. The port is shut down. | x]. Which three statements describe the IPsec protocol framework? (Choose three) AH uses IP protocol 51. AH provides encryption and integrity. AH provides integrity and authentication. ESP uses UDP protocol 50. ESP requires both authentication and encryption. ESP provides encryption, authentication, and integrity. | x8. Which three statements describe limitations in using privilege levels for assigning command authorization? (Choose three.) There is no access control to specific interfaces on a router. The root user must be assigned to each privilege level defined. Commands set on a higher privilege level are not available for lower privileged users Views are required to define the CLI commands that each user can access.

The ACL is applied to the Telnet port with the ip access-group command. Apply the ACL to the vty lines without thein orout option required when applying ACLs to interfaces. The ACL should be applied to all vty lines in thein direction to prevent anunwanted user from connecting to an unsecured port.

An interface can be assigned to multiple securityzones. Interfaces can be assigned to a zone before the zone is created. Pass, inspect,and drop options can only be applied between two zones. If traffic is to flow between all interfaces in arouter, each interface must be a member of a zone. Traffic is implicitly prevented from flowing by default among interfaces thatare members of the same zone.
To permit traffic to and from a zone member interface, a policy allowing orinspecting traffic must be configured between that zone and any other zone. | 3.

A software tool floods a switch with frames containing randomly generated sourceand destination MAC and IP addresses. | 8. When configuring a class map for zone-based policy firewall, how are thematch criteria applied when using the match-all parameter?

NTP routing updates will be sent and received on interface Serial0/0/0 of the NTP server. | ]4. Which two statements match a type of attack with an appropriate example?(Choose two.) To conduct an access attack, an attacker uses L0phtCrack to obtain a Windows server password. To conduct an access attack, an attacker uses Wireshark to capture interesting network traffic. To conduct a reconnaissance attack, an attacker initiates a ping of death attack to a targeted server. To conduct a DoS attack, an attacker uses handler systems and zombies to obtain a Windows server password. To conducta DoS attack, an attacker initiates a smurf attack by sending a large number ofICMP requests to directed broadcast addresses. To conduct a reconnaissance attack, an attacker creates a TCP SYN flood causing the server to spawn many half-open connections and
become unresponsive. | ]5. The use of which two options are required for IPsec operation? (Choosetwo.)

Which three statements should be considered when applying ACLs to aCisco router? (Choose three.) Place generic ACL entries at the top of the ACL. Place more specific ACL entries at the top of the ACL. Router-generated packets pass through ACLs on the router without filtering. ACLs always search for the most specific entry before taking any filtering action. A maximum of three IP access lists can be assigned to an interface perdirection (in or out). An access list applied to any interface without a configured ACL allows all traffic to pass. | ]8. Which consideration is important when implementing syslog in a network?
