Chapter 01 Exam Flashcards
What route would have the lowest administrative distance?
a directly connected network
a route received through the EIGRP routing protocol
a route received through the OSPF routing protocol
a static route
a directly connected network
Consider the following routing table entry for R1:
D 10.1.1.0/24 [90/2170112] via 209.165.200.226, 00:00:05, Serial0/0/0
What is the significance of the Serial0/0/0?
It is the interface on the next-hop router when the destination IP address is on the 10.1.1.0/24 network.
It is the R1 interface through which the EIGRP update was learned.
It is the interface on the final destination router that is directly connected to the 10.1.1.0/24 network.
It is the interface on R1 used to send data that is destined for 10.1.1.0/24.
It is the interface on R1 used to send data that is destined for 10.1.1.0/24.
In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host? (Choose three.)
IP address
hostname
DNS server address
subnet mask
DHCP server address
default gateway
IP address
subnet mask
default gateway
What are two common types of static routes in routing tables? (Choose two)
a built-in static route by IOS
a static route to a specific network
a static route converted from a route that is learned through a dynamic routing protocol
a static route shared between two neighboring routers
a default static route
a static route to a specific network
a default static route
Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)
A router first installs routes with higher administrative distances.
Routes with the smallest metric to a destination indicate the best path.
Administrative distance refers to the trustworthiness of a particular route.
The metric is always determined based on hop count.
The value of the administrative distance cannot be altered by the network administrator.
The metric varies depending on which Layer 3 protocol is being routed.
Routes with the smallest metric to a destination indicate the best path.
Administrative distance refers to the trustworthiness of a particular route.
What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?
It is a logical interface internal to the router.
Only one loopback interface can be enabled on a router.
It is assigned to a physical port and can be connected to other devices.
The no shutdown command is required to place this interface in an UP state.
It is a logical interface internal to the router.
What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)
IP addresses
interface descriptions
Layer 1 statuses
MAC addresses
next-hop addresses
speed and duplex settings
IP addresses
Layer 1 statuses
Which two items are used by a host device when performing an ANDing operation to determine if a destination address is on the same local network? (Choose two.)
source MAC address
subnet mask
destination MAC address
destination IP address
network number
subnet mask
destination IP address
What are two functions of a router? (Choose two.)
It controls the flow of data via the use of Layer 2 addresses.
It builds a routing table based on ARP requests.
It provides segmentation at Layer 2.
It determines the best path to send packets.
A router connects multiple IP networks.
It determines the best path to send packets.
A router connects multiple IP networks.
Which software is used for a network administrator to make the initial router configuration securely?
Telnet client software
HTTPS client software
terminal emulation client software
SSH client software
terminal emulation client software
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
to forward all packets to the device with IP address 209.165.200.226
to forward packets destined for the network 0.0.0.0 to the device with IP address 209.165.200.226
to add a dynamic route for the destination network 0.0.0.0 to the routing table
to provide a route to forward packets for which there is no route in the routing table
What is the effect of configuring the ipv6 unicast-routing command on a router?
to assign the router to the all-nodes multicast group
to enable the router as an IPv6 router
to prevent the router from joining the all-routers multicast group
to permit only unicast packets on the router
to enable the router as an IPv6 router
Fill in the blank.
When a router receives a packet, it examines the destination address of the packet and looks in the ________________ table to determine the best path to use to forward the packet.
routing
Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?
process switching
flow process
Cisco Express Forwarding
fast switching
Cisco Express Forwarding
A network administrator enters the command copy running-config startup-config. Which type of memory will the startup configuration be placed into?
NVRAM
flash
RAM
ROM
NVRAM
