An SVI can only be created for the management VLAN A default SVI is created for VLAN 1 for switch administration Creating an SVI automatically creates an associated VLAN An SVI is created automatically for each VLAN on a mulitilayer switch - ANS A default SVI is created for VLAN 1 for switch administration Which prompt is displayed when a network administrator successfully accesses the boot loader on a switch to recover from a system crash? system# switch# switch: system: - ANS switch: Which router bootup sequence is correct?​ 1 - Perform the POST and load the startup configuration file 2 - Locate and load the bootstrap program 3 - Locate and load the Cisco IOS software 1 - Perform the POST and load the bootstrap program 2 - Locate and load the Cisco IOS program 3 - Locate and load the startup configuration file or enter setup mode 1 - Perform the POST and load the Cisco IOS software 2 - Locate and load the startup configuration file or enter setup mode 3 - Locate and load the bootstrap program 1 - Perform the POST and load the bootstrap program 2 - Locate and load the startup configuration file or enter setup mode 3 - Locate and load the Cisco IOS software - ANS 1 - Perform the POST and load the bootstrap program 2 - Locate and load the Cisco IOS program 3 - Locate and load the startup configuration file or enter setup mode What is the first action in the boot sequence when a switch is powered on? Load the default Cisco IOS software Load boot loader software Load a Power-on-self-test program Low-level CPU initialization - ANS Load a Power-on-self-test program What must an administrator have in order to reset a lost password on a router? Access to another router Physical access to the router A TFTP server A crossover cable - ANS Physical access to the router When configuring a switch for SSH access, what other command that is associated with the login local command is required to be entered on the switch?

Show running-config Show ip interface brief Show history Show interfaces - ANS Show interfaces Which port speed will be autonegotiated between a host with a 1 Gbps NIC connecting to a Cisco Catalyst 2960 switch with a 100 Mbps port? 10 Mbps 100 Mbps 1 Gbps 10 Gbps - ANS 100 Mbps Which device separates broadcast domains? Access point Hub Router Switch - ANS Router Which two special characteristics do LAN switches use to alleviate network congestion? (Choose two.) Fast port speeds Fast internal switching Low port densities Small frame buffers - ANS Fast port speeds Fast internal switching Which statement is true about broadcast and collision domains? The size of the collision domain can be reduced by adding hubs to a network Adding a router to a network will increase the size of the collision domain The more interfaces a router has the larger the resulting broadcast domain Adding a switch to a network will increase the size of the broadcast domain - ANS Adding a switch to a network will increase the size of the broadcast domain What is one function of a Layer 2 switch? Learns the port assigned to a host by examining the destination MAC address Duplicates the electrical signal of each frame to every port Forwards data based on logical addressing Determines which interface is used to forward a frame based on the destination MAC address - ANS Determines which interface is used to forward a frame based on the destination MAC address What is the significant difference between a hub and a Layer 2 LAN switch? A hub divides collision domains, and a switch divides broadcast domains A switch creates many smaller collision domains, and a hub increases the size of a single collision domain
