Question 1 of 24
1. Question
1 pointsA network administrator enters the command copy running-config startup-config. Which type of memory will the startup configuration be placed into?Correct
Incorrect
A router contains four types of memory:
- RAM – volatile memory used to store the running IOS, running configuration file, routing table, ARP table, as well as serve as a packet buffer
- ROM – nonvolatile memory used to hold a limited version of the IOS, bootup instructions, and basic diagnostic software
- NVRAM – nonvolatile memory used to hold the startup configuration file
- Flash – nonvolatile memory used to hold the IOS and other system files

Question 5 of 24
5. Question
3 pointsIn order for packets to be sent to a remote destination, what three pieces of information must be configured on a host? (Choose three.)Correct
Incorrect
A host can use its IP address and subnet mask to determine if a destination is on the same network or on a remote network. If it is on a remote network, the host will need a configured default gateway in order to send packets to the remote destination. DNS servers translate names into IP addresses, and DHCP servers are used to automatically assign IP addressing information to hosts. Neither of these servers has to be configured for basic remote connectivity.Hint

Question 10 of 24
10. Question
2 pointsWhich 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.)Correct
Incorrect
The result of ANDing any IP address with a subnet mask is a network number. If the source network number is the same as the destination network number, the data stays on the local network. If the destination network number is different, the packet is sent to the default gateway (the router that will send the packet onward toward the destination network).Hint

Question 13 of 24
13. Question
1 pointsRefer 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?
CCNA 2 RSE 6.0 Chapter 1 Exam Answers 2018 2019 02 Correct
Incorrect
When PC1 forms the various headers attached to the data one of those headers is the Layer 2 header. Because PC1 connects to an Ethernet network, an Ethernet header is used. The source MAC address will be the MAC address of PC1 and the destination MAC address will be that of G0/0 on R1. When R1 gets that information, the router removes the Layer 2 header and creates a new one for the type of network the data will be placed onto (the serial link).Hint

Question 14 of 24
14. Question
1 pointsRefer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227?
CCNA 2 RSE 6.0 Chapter 1 Exam Answers 2018 2019 07 Correct
Incorrect
After a router determines the destination network by ANDing the destination IP address with the subnet mask, the router examines the routing table for the resulting destination network number. When a match is found, the packet is sent to the interface associated with the network number. When no routing table entry is found for the particular network, the default gateway or gateway of last resort (if configured or known) is used. If there is no gateway of last resort, the packet is dropped. In this instance, the 192.168.12.224 network is not found in the routing table and the router uses the gateway of last resort. The gateway of last resort is the IP address of 209.165.200.226. The router knows this is an IP address that is associated with the 209.165.200.224 network. The router then proceeds to transmit the packet out the Serial0/0/0 interface, or the interface that is associated with 209.165.200.224.Hint

Question 17 of 24
17. Question
2 pointsWhich two statements correctly describe the concepts of administrative distance and metric? (Choose two.)Correct
Incorrect
A metric is calculated by a routing protocol and is used to determine the best path (smallest metric value) to a remote network. Administrative distance (AD) is used when a router has two or more routes to a remote destination that were learned from different sources. The source with the lowest AD is installed in the routing table.Hint

The Serial0/0/0 indicates the outgoing interface on R1 that is used to send packets for the 10.1.1.0/24 destination network. -
Question 19 of 24
19. Question
2 pointsRefer 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.)
CCNA 2 RSE 6.0 Chapter 1 Exam Answers 2018 2019 05 Correct
Incorrect
From the routing table, R1 knows two directly connected networks and the multicast network (FF00::/8). It does not know any routes to remote networks. The entry 2001:DB8:ACAD:A::12/128 is the local host interface route.Hint

Question 20 of 24
20. Question
1 pointsA 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?Correct
Incorrect
A directly connected network will be added to the routing table when these three conditions are met: (1) the interface is configured with a valid IP address; (2) it is activated with no shutdown command; and (3) it receives a carrier signal from another device that is connected to the interface. An incorrect subnet mask for an IPv4 address will not prevent its appearance in the routing table, although the error may prevent successful communications.Hint

21. Question
1 pointsA 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?Correct
Incorrect
The command ip route 0.0.0.0 0.0.0.0 <next hop> adds a default route to the routing table of a router. When the router receives a packet and does not have a specific route toward the destination, it forwards the packet to the next hop indicated in the default route. A route created with the ip route command is a static route, not a dynamic route.Hint
