- no cdp run - cdp enable
Which two characteristics match extended range VLANS?
- they are saved in the running-config file by default - VLAN IDs exist between 1006 & 4094
Which two conditions should the network administrator verify before attempting to upgrade a Cisco IOS image using a TFTP server?
- verify connectivity between the router and TFTP server using the "ping" command - verify that there is enough flash memory for the new Cisco IOS image using the "show flash" command
In the IOS image named c1900-univeralk9-mz.SPA.152-3.T.bin, which part identifies the major release number?
15
How long is the evaluation license period for Cisco IOS Release 15.0 software packages?
60 days
Which two modes does Cisco recommend when configuring a particular switch port?
Access Trunk
What is the difference between CDP and LLDP?
CDP is a proprietary protocol, whereas LLDP is a vendor-neutral protocol
Which syslog message type is accessible only to an administrator and only via the Cisco CLI?
Debugging
What can a network administrator do to access a router if the password has been lost?
From ROMMON mode, configure the router to ignore the startup configuration when the router initializes
Beginning with the Cisco IOS Software Release 15.0, which license is a prerequisite for installing additional technology pack licenses?
IPBase
When logging is used, which severity level indicates that a device is unusable?
Level 0 - emergency
A network administrator configures the port-security feature on a switch. The security policy specifies that each access port should allow up to two MAC addresses. When the maximum number of MAC addresses is reached, a frame with an unknown source MAC address is dropped and a notification is sent to the syslog sever. Which security violation mode should be configured for each access port?
Restrict
Which protocol or service allows network administrators to receive system messages that are provided by network devices?
Syslog
What is one difference between using Telnet or SSH to connect to a network device for management purposes?
Telnet sends a username and password in plain text, whereas SSH encrypts the username and password.
Which interface is the default location that would contain the IP address used to manage a 24-port Ethernet switch?
VLAN 1
Which type of VLAN is used to designate which traffic untagged when crossing a trunk port?
a native VLAN
What VLANs are allowed across a trunk when the range of allowed VLAN's is set to the default value?
all VLANs will be allowed across the trunk
An administrator has determined that the traffic from a switch that corresponds to a VLAN is not being received on another switch over a trunk link. What could be the problem?
allowed VLANs on trunks
A network technician is attempting a password recovery on a router. From ROM-MON mode, which command must be entered to bypass the startup-configuration file?
confreg 0x2142
Which destination do Cisco routers and switches use by default when sending syslog messages for all severity levels?
console
An administrator issues the command "confreg 0x2142" at the rommon 1> prompt. What is the effect when this router is rebooted?
contents in NVRAM will be ignored
A Cisco Catalyst switch has been added to support the use of multiple VLANS as part of an enterprise network. The network technician finds it necessary to clear all VLAN information from the switch to incorporate a new network design. What should the technician do to accomplish this task?
delete the startup configuration file and the vlan.dat file in the flash memory of the switch and reboot the switch
What must the network administrator do to remove Fast Ethernet port Fa0/1 from VLAN 2 and assign it to VLAN 3?
enter the "switchport access vlan 3" command in interface configuration mode
Which two statements are true about using full-duplex Fast Ethernet?
full-duplex fast Ethernet offers 100 percent efficiency in both directions performance is improved with bidirectional flow of data
Which statement describes the port speed LED on the Cisco Catalyst 2960 switch?
if the LED is green, the port is operating at 100 Mb/s
Which action will bring an error-disabled switchport back to an operational state?
issue the "shutdown" then "no shutdown" interface commands
A Cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a "switchport trunk allowed vlan 30" command Fa0/5?
it allows only VLAN 30 on Fa0/5
What statement describes a Cisco IOS image with the "universalk9_npe" designation for Cisco ISR G2 routers?
it is an IOS version that, at the request of some countries, removes any strong cryptographic functionality
Which command is used to configure a one-time acceptance of the EULA for all Cisco IOS software packages and features?
