Cisco 2 practice
How many classful networks are summarized by the static summary route ip route 192.168.32.0 255.255.248.0 S0/0/0?
8
An administrator attempts to change the router ID on a router that is running OSPFv3 by changing the IPv4 address on the router loopback interface. Once the IPv4 address is changed, the administrator notes that the router ID did not change. What two actions can the administrator take so that the router will use the new IPv4 address as the router ID?
Reboot the router, and Clear the IPv6 OSPF process.
Which two commands should be implemented to return a Cisco 3560 trunk port to its default configuration?
S1(config-if)# no switchport trunk native vlan, S1(config-if)# no switchport trunk allowed vlan
An administrator created and applied an outbound Telnet extended ACL on a router to prevent router-initiated Telnet sessions. What is a consequence of this configuration?
The ACL will not work as desired because an outbound ACL cannot block router-initiated traffic.
When does a switch use frame filtering?
The destination MAC address is for a host on the same network segment as the source of the traffic.
Which two keywords can be used in an access control list to replace a wildcard mask or address and wildcard mask pair?
The first 28 bits of a supplied IP address will be matched., and The last four bits of a supplied IP address will be ignored.
What best describes the operation of distance vector routing protocols?
They send their routing tables to directly connected neighbors.
OSPF advertisements will include the network on the interface with the IPv4 address 192.168.10.1.
a collapsed core network design
What is an advantage of using dynamic routing protocols instead of static routing?
ability to actively search for new routes if the current path becomes unavailable
Which two keywords can be used in an access control list to replace a wildcard mask or address and wildcard mask pair?
any and host
modularity
each layer has specific roles and functions that can scale easily
Which type of static route typically uses the distance parameter in the ip route global configuration command?
floating static route
ROM
holds a small, limited functionality operating system
flash
holds the full operating system
RAM
holds the running configuration
NVRAM
holds the startup configuration file
hierarchical
layers minimize the number of devices on any one tier that share a single point of failure
A network administrator is testing IPv6 connectivity to a web server. The network administrator does not want any other host to connect to the web server except for the one test computer. Which type of IPv6 ACL could be used for this situation?
only a named ACL
In a routing table which route can never be an ultimate route?
parent route
resiliency
provides an 'always on' dependability
What does an OSPF area contain?
routers that have the same link-state information in their LSDBs
What is associated with link-state routing protocols?
shortest-path first calculations
Which command will verify the status of both the physical and the virtual interfaces on a switch?
show ip interface brief
flexibility
this shares the network traffic load across all network resources
step four in the DHCP process
DHCPACK (unicast)
Which DHCP IPv4 message contains the following information? Destination address: 255.255.255.255 Client IPv4 address: 0.0.0.0 Default gateway address: 0.0.0.0 Subnet mask: 0.0.0.0
DHCPDISCOVER
step one in the DHCP process
DHCPDISCOVER(broadcast)
step two in the DHCP process
DHCPOFFER (unicast)
step three in the DHCP process
DHCPREQUEST (broadcast)
what command configures a switch port to operate in the full-duplex mode?
DUPLEX FULL
How is the router ID for an OSPFv3 router determined?
How is the router ID for an OSPFv3 router determined?
Which two statements are characteristics of routed ports on a multilayer switch?
In a switched network, they are mostly configured between switches at the core and distribution layers, They are not associated with a particular VLAN.
A client is using SLAAC to obtain an IPv6 address for its interface. After an address has been generated and applied to the interface, what must the client do before it can begin to use this IPv6 address?
It must send an ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.
When routing a large number of VLANs, what are two disadvantages of using the router-on-a-stick inter-VLAN routing method rather than the multilayer switch inter-VLAN routing method?
Multiple subinterfaces may impact the traffic flow speed, A dedicated router is required.
What is the effect of entering the network 192.168.10.1 0.0.0.0 area 0 command in router configuration mode?
OSPF advertisements will include the network on the interface with the IPv4 address 192.168.10.1.
