What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?​ It is a logical interface internal to the router. It is assigned to a physical port and can be connected to other devices. Only one loopback interface can be enabled on a router.​ The no shutdown command is required to place this interface in an UP state.​

It is a logical interface internal to the router.

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 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. It is the R1 interface through which the EIGRP update was learned.

It is the interface on R1 used to send data that is destined for 10.1.1.0/24.

What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.) speed and duplex settings Layer 1 statuses interface descriptions IP addresses next-hop addresses MAC addresses

Layer 1 statuses IP addresses

A network administrator enters the command copy running-config startup-config . Which type of memory will the startup configuration be placed into? flash NVRAM ROM RAM

NVRAM

Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.) R1 does not know a route to any remote networks. The network FF00::/8 is installed through a static route command. Packets that are destined for the network 2001:DB8:ACAD:2::/64 will be forwarded through Fa0/1. Packets that are destined for the network 2001:DB8:ACAD:2::54/128 will be forwarded through Fa0/0. The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12.

R1 does not know a route to any remote networks. The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12.

Refer to the exhibit. What does R1 use as the MAC address of the destination when constructing the frame that will go from R1 to Server B? R1 leaves the field blank and forwards the data to the PC. The packet is encapsulated into a PPP frame, and R1 adds the PPP destination address to the frame. R1 uses the destination MAC address of S1. If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request.

R1 uses the destination MAC address of S1.

Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.) The value of the administrative distance cannot be altered by the network administrator. The metric is always determined based on hop count. Routes with the smallest metric to a destination indicate the best path. A router first installs routes with higher administrative distances. Administrative distance refers to the trustworthiness of a particular route. 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.

Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227? Drop the packet. Send the packet out the GigabitEthernet0/0 interface. Send the packet out the Serial0/0/0 interface. Send the packet out the GigabitEthernet0/1 interface.

Send the packet out the Serial0/0/0 interface.

What are two common types of static routes in routing tables? (Choose two) a static route shared between two neighboring routers a built-in static route by IOS a default static route a static route to a specific network a static route converted from a route that is learned through a dynamic routing protocol

a default static route a static route to a specific network

What route would have the lowest administrative distance? a directly connected network a route received through the EIGRP routing protocol a static route a route received through the OSPF routing protocol

a directly connected network

Refer to the exhibit. A network administrator has configured R1 as shown. When the administrator checks the status of the serial interface, the interface is shown as being administratively down. What additional command must be entered on the serial interface of R1 to bring the interface up? no shutdown end clockrate 128000 IPv6 enable

no shutdown

Refer to the exhibit. If PC1 is sending a packet to PC2 and routing has been configured between the two routers, what will R1 do with the Ethernet frame header attached by PC1? open the header and use it to determine whether the data is to be sent out S0/0/0 remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0 open the header and replace the destination MAC address with a new one nothing, because the router has a route to the destination network

remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0

What are two functions of a router? (Choose two.) A router connects multiple IP networks. It provides segmentation at Layer 2. It controls the flow of data via the use of Layer 2 addresses. It builds a routing table based on ARP requests. It determines the best path to send packets.

A router connects multiple IP networks. It determines the best path to send packets.

Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table? flow process fast switching process switching Cisco Express Forwarding

Cisco Express Forwarding

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? 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 configuration needs to be saved first. The interface fa0/0 has not been activated.

The interface fa0/0 has not been activated.

Which two parameters are used by EIGRP as metrics to select the best path to reach a network? (Choose two.)​ resiliency delay jitter confidentiality bandwidth hop count

delay bandwidth

When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination? source MAC address destination IP address source IP address destination MAC address

What is the effect of configuring the ipv6 unicast-routing command on a 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 to assign the router to the all-nodes multicast group

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 add a dynamic route for the destination network 0.0.0.0 to the routing table to forward all packets 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 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
