A network administrator has examined the routing table of a router and noted that the entry for the destination network 172.16.4.0/24 begins with the letter D. What does this letter signify?
The route source was learned dynamically.
Which two route source codes are automatically created within a routing table whenever a router interface is configured with an IP address and activated? (Choose two.)
C, L
What is the purpose of classifying Cisco IP routing table entries as ultimate route, level 1 route, level 1 parent route, and level 2 child routes?
to explain the operation of the hierarchical structure of the routing table
A network administrator is examining a RIPv2 routing table and notices that several subnets are advertised in individual entries. What can an administrator do to enable a RIPv2 router to automatically group multiple directly attached subnetworks into a single network statement?
Use the auto-summary command
What are two functions of dynamic routing protocols? (Choose two.)
to maintain routing tables and to discover the network
__________________ protocols are used to dynamically exchange routing information between routers.
routing
What type of route has a network address with a subnet mask that is less than the classful equivalent?
a supernet route
In the process of building and maintaining a larger network, you will find that ___________________ routing is simpler to configure than static routing.
dynamic
Refer to the exhibit. All hosts and router interfaces are configured correctly. Pings to the server from both H1 and H2 and pings between H1 and H2 are not successful. What is causing this problem?
RIPv2 is misconfigured on router R2.
Match the steps that are taken by a router in the route look up process when it receives a packet, there is no match, and the packet is eventually dropped. (Not all options are used.)
Step 1: examining level 1 network routes for the best match
Step 2: examining child routes of the parent route for the best match
Step 3: searching level 1 supernet routes for the best match
Step 4: determining if a default route exists
Step 5: dropping the packet
Which route would be used to forward a packet with a source IPv6 address of 2001:DB8:F00D:1::1 and a destination IPv6 address of 2001:DB8:CAFE:2::1?
R 2001:DB8:CAFE:2::/64 [120/3] via FE80::201:84FF:FEAC:8501, GigabitEthernet0/0
Refer to the exhibit. What is the administrative distance value of the route for router R1 to reach the destination IPv6 address of 2001:DB8:CAFE:4::A?
120
What occurs next in the router lookup process after a router identifies a destination IPv6 address and locates a matching level 1 network route?
The router forwards the packet
Match the routing table entry to the corresponding function. (Not all options are used.)
identifies how the route was learned: Route Source
identifies the address of a remote network: Destination Network
identifies the value assigned to reach a remote network: Metric
identifies the trustworthiness of a route source: Administrative Distance
Refer to the exhibit. What is the metric to forward a data packet with the IPv6 destination address 2001:DB8:ACAD:E:240:BFF:FED4:9DD2?
