RSC-25B_Class-029-20 Exam Questions and Answers 100% Pass When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination? - Answer- destination IP address 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.) - Answer- -destination IP address -subnet mask 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? - Answer- to provide a route to forward packets for which there is no route in the routing table 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? - Answer- The interface fa0/0 has not been activated. 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? - Answer- no shutdown Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227? - Answer- Send the packet out the Serial0/0/0 interface. Which two parameters are used by EIGRP as metrics to select the best path to reach a network? (Choose two.) - Answer- -delay -bandwidth What is the effect of configuring the ipv6 unicast-routing command on a router? - Answer- to enable the router as an IPv6 router What is a characteristic of an IPv4 loopback interface on a Cisco IOS router? - Answer- It is a logical interface internal to the router. Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table? - Answer- Cisco Express Forwarding 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? - Answer- 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.) - Answer- -A router connects multiple IP networks. -It determines the best path to send packets. 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? - Answer- It is the interface on R1 used to send data that is destined for 10.1.1.0/24. What route would have the lowest administrative distance? - Answer- a directly connected network Which software is used for a network administrator to make the initial router configuration securely? - Answer- terminal emulation client software What are two common types of static routes in routing tables? (Choose two) - Answer- - a static route to a specific network -a default static route 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? - Answer- If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request. Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.) - Answer- -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. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.) - Answer- -The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12. -R1 does not know a route to any remote networks. Refer to the exhibit. PC A sends a request to Server B. What IPv4 address is used in the destination field in the packet as the packet leaves PC A? - Answer- 192.168.12.16 In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host? (Choose three.) - Answer- -subnet mask -default gateway -IP address What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.) - Answer- -IP addresses -Layer 1 statuses A network administrator enters the command copy running-config startup-config . Which type of memory will the startup configuration be placed into? - Answer- NVRAM During the process of encapsulation, how does the PC determine if the packet is destined for a host on a remote network? - Answer- by performing the AND operation on the destination IP address and its own subnet mask The output of the show ip route command contains the following entry: S 10.2.0.0 [1/0] via 172.16.2.2. What value is indicated by the 1 in the [1/0] portion of the output? - Answer- administrative distance What is a gateway of last resort? - Answer- the IP address of another router Which two statements describe characteristics of load balancin
