Hoofdstuk 1 Flashcards
A network administrator enters the command copy running-config startup-config. Which type of memory will the startup configuration be placed into?
flash RAM NVRAM ROM
NVRAM
Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?
fast switching Cisco Express Forwarding process switching flow process
Cisco Express Forwarding
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
What are two functions of a router? (Choose two.)
A router connects multiple IP networks. It controls the flow of data via the use of Layer 2 addresses. It determines the best path to send packets. It provides segmentation at Layer 2. It builds a routing table based on ARP requests.
A router connects multiple IP networks.
It determines the best path to send packets.
In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host? (Choose three.)
hostname
IP address
subnet mask
default gateway
DNS server address
DHCP server address
IP address
subnet mask
default gateway
Which software is used for a network administrator to make the initial router configuration securely?
SSH client software Telnet client software HTTPS client software terminal emulation client software
terminal emulation client software
What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?
The no shutdown command is required to place this interface in an UP state. 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.
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
MAC addresses
Layer 1 statuses
next-hop addresses
interface descriptions
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.)
destination IP address
destination MAC address
source MAC address
subnet mask
network number
destination IP address
subnet mask
Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)
Administrative distance refers to the trustworthiness of a particular route. A router first installs routes with higher administrative distances. The value of the administrative distance can not be altered by the network administrator. Routes with the smallest metric to a destination indicate the best path. The metric is always determined based on hop count. The metric varies depending which Layer 3 protocol is being routed, such as IP.
Administrative distance refers to the trustworthiness of a particular route.
Routes with the smallest metric to a destination indicate the best path.
Which two parameters are used by EIGRP as metrics to select the best path to reach a network? (Choose two.)
hop count
bandwidth
jitter
resiliency
delay
confidentiality
bandwidth
delay
What route would have the lowest administrative distance?
a directly connected network a static route a route received through the EIGRP routing protocol a route received through the OSPF routing protocol
a static route
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 R1 used to send data that is destined for 10.1.1.0/24. 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 the next-hop router when the destination IP address is on 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.
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. The configuration needs to be saved first. No packets with a destination network of 172.16.1.0 have been sent to R1. The subnet mask is incorrect for the IPv4 address.
The interface fa0/0 has not been activated.
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 forward all packets 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 forward packets destined for the network 0.0.0.0 to the device with IP address 209.165.200.226 to provide a route to forward packets for which there is no route in the routing table
to provide a route to forward packets for which there is no route in the routing table
