Module Group 5 (14-16)
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 three advantages are provided by static routing? (Choose three.)
Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does. Static routing does not advertise over the network, thus providing better security. The path a static route uses to send data is known
Refer to the exhibit. What action will R3 take to forward a frame if it does not have an entry in the ARP table to resolve a destination MAC address?
Sends an ARP request
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
A network administrator uses the command ip route 172.18.0.0 255.255.0.0 S0/0/1 to configure a floating static route on a router. That route will function as a backup route to reach the EIGRP learned network 172.18.0.0/16. After this configuration, the EIGRP route is removed from the routing table even though EIGRP is still functioning properly. Why is the static route not functioning as intended?
The administrative distance value is not high enough on the static route.
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
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
Refer to the exhibit. True or False? R1 must encapsulate received packets into new frames before forwarding them to R2.
True
Refer to the exhibit. True or False? R2 will forward frames to R3 with an all 1s Layer 2 address.
True
How is the destination network in an IPv6 static route identified?
Using an IPv6 prefix and prefix length
Which IPv4 static route statement is true?
Using the exit interface only is common in a point-to-point configuration.
A network administrator has entered the following command: ip route 192.168.10.64 255.255.255.192 serial0/0/1 When the network administrator enters the command show ip route, the route is not in the routing table. What should the administrator do next?
Verify that the serial 0/0/1 interface is active and available
A network administrator is configuring a route to forward packets to a specific web server. What type of route should be configured by the administrator?
a host route
What are two common types of static routes in routing tables? (Choose two)
a static route to a specific network a default static route
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?

Which static route statement shows a recursive IPv6 static route?
ipv6 route 2001:db8:cafe:1::/56 2001:db8:1000:10::1
Which command would create a valid IPv6 default route?
ipv6 route ::/0 2001:db8:acad:2::a
Which two methods can be used to identify the next hop in a static route? (Choose two.)
next hop IP address exit interface
What network address and subnet mask combination would be used to create a default static route that matches any IPv4 destination?
0.0.0.0 0.0.0.0
Which sequence correctly identifies the order of the steps that a router will perform when it receives a packet on an Ethernet interface?
1. The router examines the destination MAC address. 2. The router identifies the Ethernet Type field. 3. The router de-encapsulates the Ethernet frame. 4. The router examines the destination IP address.
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 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 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
True or False? A default route can only be a static route.
False
What command, or set of commands, would be used to determine if the following configuration on router HQ works as designed?
HQ(config)# interface serial 0/1/0 HQ(config-if)# shutdown HQ(config-if)# end HQ# show ip route
What is the purpose of a floating static route?
It allows an alternate connection to be used when the preferred link fails.
Which statement describes the sequence of processes executed by a router when it receives a packet from a host to be delivered to a host on another network?
It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host.
What does the letter C mean next to an entry in the output of the show ip route command?
It identifies a network that is directly connected to the router.
What is a characteristic of a default static route?
It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.
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 a next-hop router.
A static route has been configured on a router. However, the destination network no longer exists. What should an administrator do to remove the static route from the routing table?
Remove the route using the no ip route command.
Which IPv6 static route would serve as a backup route to a dynamic route learned through OSPF?
Router1(config)# ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::2 200
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 a next-hop router
