CISCO 2 Module 14
What address and prefix length is used when configuring an IPv6 default static route?
::/0
What are two functions of a router? (Choose two.)
A router connects multiple IP networks It determines the best path to send packets
Which packet forwarding method is used by default on Cisco routers?
Cisco Express Forwarding
Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?
Cisco Express Forwarding
Which type of routing automatically adapts to topology changes?
Dynamic routing protocols
True or False? A default route can only be a static route.
False
What action will a router take on a packet with a destination IP address that is on a remote network?
It will forward the packet to the next-hop router
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.)
L C
Which route entry would be used for a packet with a destination IP address that matches an IP address of one of the router interfaces?
L for Local
Which two route sources have the ability to automatically discover a new best path when there is a change in the topology? (Choose two.)
OSPF EIGRP
Which routing table principle is not correct?
Routing information about a path from one network to another also provides routing information about the reverse, or return, path.
A network administrator configures a static route for the same destination network that was learned automatically by the router using OSPF. Which route will be installed and why?
Static route because it has a lower administrative distance
What are two reasons why an administrator might choose to use static routing rather than dynamic routing? (Choose two.)
Static routing uses less router processing and bandwidth Static routing is more secure
What type of network is accessed by a single route and the router has only one neighbor?
Stub network
Which three advantages are provided by static routing? (Choose three.)
The path a static route uses to send data is known Static routing typically uses less network bandwidth and fewer CPU operations that dynamic routing does Static routing does not advertise over the network, thus providing better security
If a router needs to send an ARP Request for the destination IPv4 address of the packet, this means the packet will be forwarded:
To the device with the destination IPv4 address of the packet
If a router needs to send an ARP Request for the IPv4 address in one of its route entries, this means the packet will be forwarded:
To the next-hop router
What are two common types of static routes in routing tables? (Choose two)
a default static route a static route to a specific network
What is an advantage of using dynamic routing protocols instead of static routing?
ability to actively search for new routes if the current path becomes unavailable
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?
administrative distance
Which value represents the "trustworthiness" of a route and is used to determine which route to install into the routing table when there are multiple routes toward the same destination?
administrative distance
What metric is used by OSPF to determine the best path?
cost
Which type of route would typically be used on a border router so that devices inside the company could access the Internet?
default
Which type of static route creates a gateway of last resort?
default static route
Which of the following routes may be found in a routing table? (Choose all that apply.)
directly connected networks static routes dynamic routing protocol routes default route
What term is used to describe routing over two or more paths to a destination with equal cost metrics?
equal cost load balancing
Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?
gateway of last resort
What is used to determine the minimum number of far-left bits that must match between the prefix in the route entry and the destination IP address.
prefix length in the routing table entry
What table does a router use to determine how to forward an IP packet?
routing table
What type of routing is typically used with a stub network?
static routes
When a router learns that multiple paths are available to a destination network from the same routing protocol, which factor is considered by a router to choose the best path to forward a packet?
the lowest metric
What are two functions of dynamic routing protocols? (Choose two.)
to maintain routing tables to discover the network
