100
Which dynamic routing protocol was developed to interconnect different Internet service providers?
BGP
What is a characteristic of a static route that matches all packets?
It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.

R1(config-line)# access-class 1 in
Where are dynamically learned MAC addresses stored when sticky learning is enabled with the switchport port-security mac-address sticky command?
RAM
Which routing protocol is limited to smaller network implementations because it does not accommodate growth for larger networks?
RIP
Which route is the best match for a packet entering a router with a destination address of 10.16.0.2?
S 10.16.0.0/24 [1/0] via 192.168.0.9
The network administrator configures the router with the ip route 172.16.1.0 255.255.255.0 172.16.2.2 command. How will this route appear in the routing table?
S 172.16.1.0 [1/0] via 172.16.2.2
A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?
Segment the LAN into smaller LANs and route between them.
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.
A network administrator configures a static route on the edge router of a network to assign a gateway of last resort. How would a network administrator configure the edge router to automatically share this route within RIP?
Use the default-information originate command.
Which interface is the default location that would contain the IP address used to manage a 24-port Ethernet switch?
VLAN
A router is configured to participate in multiple routing protocol: RIP, EIGRP, and OSPF. The router must send a packet to network 192.168.14.0. Which route will be used to forward the traffic?
a 192.168.14.0/26 route that is learned via RIP
A ___________________________________ network is one that uses the same infrastructure to carry voice, data, and video signals.
data services
What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
default route
What is a definition of a two-tier LAN network design?
distribution and core layers collapsed into one tier, and the access layer on a separate tier
What is the effect of using the switchport port-security command?
enables port security on an interface
A local law firm is redesigning the company network so that all 20 employees can be connected to a LAN and to the Internet. The law firm would prefer a low cost and easy solution for the project. What type of switch should be selected?
fixed configuration
When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?
native VLAN ID
What is the destination address in the header of a broadcast frame?
FF-FF-FF-FF-FF-FF
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.
Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 How would an administrator test this configuration?
Manually shut down the router interface used as a primary route.
Which route would be used to forward a packet with a source IP address of 192.168.10.1 and a destination IP address of 10.1.1.1?
O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0
A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0. However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?
The interface fa0/0 has not been activated.
What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?
The static route is removed from the routing table.
What is a collapsed core in a network design?
a combination of the functionality of the distribution and core layers
Which solution would help a college alleviate network congestion due to collisions?
a high port density switch
What is the purpose of the passive-interface command?
allows a router to receive routing updates on an interface but not send updates via that interface
Which type of route will require a router to perform a recursive lookup?
an ultimate route that is using a next hop IP address on a router that is not using CEF
A network administrator has entered a static route to an Ethernet LAN that is connected to an adjacent router. However, the route is not shown in the routing table. Which command would the administrator use to verify that the exit interface is up?
show ip interface brief
What does the term "port density" represent for an Ethernet switch?
the number of available ports
Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router?
to be used as a backup route
What is the effect of configuring the ipv6 unicast-routing command on a router?
to enable the router as an IPv6 router
A network administrator configures a router by the command ip route 0.0.0.0 0.0.0.0 209.165.200.226. What is the purpose of this command?
to provide a route to forward packets for which there is no route in the routing table
When configuring a router as part of a router-on-a-stick inter-VLAN routing topology, where should the IP address be assigned?
to the subinterface
In which situation would a technician use the show interfaces switch command?
when packets are being dropped from a particular directly attached host
In which configuration would an outbound ACL placement be preferred over an inbound ACL placement?
when the ACL is applied to an outbound interface to filter packets coming from multiple inbound interfaces before the packets exit the interface
