Question 1

As the network engineer, you are configuring the Fast Ethernet interface. You have issued the following command to the fa0/0 interface: ip address 200.16.24.1 255.255.255.0. Which of the following must be TRUE before the router can add this information to its routing table?

A) The interface status codes for the interface must be in the Up and Up condition.
B) The interface must be administratively turned off.
C) The interface must have the no shutdown command issued.
D) The router must be able to communicate with its neighbor first.

The interface status codes for the interface must be in the Up and Up condition.
The interface must have the no shutdown command issued.

Accepted Answer

A) For a connected route to be inserted into the IPv4 routing table, the interface where the ip address command was issued must be in a fully operational state (up/up). The configuration of an interface with the shutdown command would prevent it from having this status.
C) For a connected route to be inserted into the IPv4 routing table, the interface where the ip address command was issued must be in a fully operational state (up/up). The configuration of an interface with the shutdown command would prevent it from having this status.

Question 2

You need to configure a default route. Which of the following commands is the correct way to set the default route out of your network?&#10;A) ip route 0.0.0.0.0.0.0.0 172.20.3.2&#10;B) ip route 0.0.0.0 0.0.0.0 172.20.3.2&#10;C) ip route 0.0.0.0 172.20.3.2&#10;D) ip route any 172.20.3.2

Accepted Answer

B) The ip route 0.0.0.0 0.0.0.0 172.20.3.2 option is the correct answer. The correct syntax includes ip route 0.0.0.0 0.0.0.0 {next-hop-address | outbound-interface}.

Question 3

Which conditions must be met for a router to process a frame?&#10;A) The frame isn't marked Discard Eligible.&#10;B) The frame source address is the same as the local address (Layer 2).&#10;C) The frame has no errors.&#10;D) The frame destination address is the same as the local address (Layer 2).

Accepted Answer

C) Two conditions must be met for any device to process a frame (including routers): The frame must be free of errors (per any check mechanism; that is, FCS), and it must have a destination address (Layer 2) that matches the interface from which it was received.
D) Two conditions must be met for any device to process a frame (including routers): The frame must be free of errors (per any check mechanism; that is, FCS), and it must have a destination address (Layer 2) that matches the interface from which it was received.

Question 4

What is the process of removing the Layer 2 header and trailer information to reveal the Layer 3 packet?&#10;A) De-encapsulation&#10;B) Encapsulation&#10;C) Encryption&#10;D) Decryption

Accepted Answer

A) As each layer of header and footer is added to the data that is eventually transmitted at the physical layer, it is encapsulated with successive headers and footers. The removal of these headers and footers at each level is referred to as de-encapsulation.

Question 5

What type of route adds the subnet to the routing table of a Cisco device when the ip address command is issued on an interface with a state of up/up?&#10;A) Local route&#10;B) Connected route&#10;C) Static route&#10;D) Interface route

Accepted Answer

B) Two different routes are added to the routing table of a Cisco device when the ip address command is issued to an interface with a state of up/up. The connected route adds a route that includes the whole subnet for the configured address; the local route adds a host route that is specific to the single address configured (/32).

Question 6

What type of route adds the host to the routing table of a Cisco device when the ip address command is issued on an interface with a state of up/up?&#10;A) Local route&#10;B) Connected route&#10;C) Static route&#10;D) Interface route

Accepted Answer

A) Two different routes are added to the routing table of a Cisco device when the ip address command is issued to an interface with a state of up/up. The connected route adds a route that includes the whole subnet for the configured address; the local route adds a host route that is specific to the single address configured (/32).

Question 7

The ________ configuration creates a subinterface for each VLAN on the trunk and routes all frames associated with each VLAN ID as it comes in or out of the subinterface.&#10;A) MLS&#10;B) CEF&#10;C) ROAS&#10;D) Fast switching

Accepted Answer

C) When a router must handle the routing for traffic from multiple VLANs, it is often easiest to create a trunk between the router and the adjoining switch. When this is complete, subinterfaces are created on the router to handle the traffic for each VLAN. This type of configuration is referred to as Router On a Stick (ROAS).

Question 8

When configuring a trunk between a router and a switch, which command must be configured on the switch to ensure that the trunk comes up?&#10;A) switchport mode dynamic desirable&#10;B) switchport mode dynamic auto&#10;C) switchport mode access&#10;D) switchport mode trunk

Accepted Answer

D) Routers do not support the Dynamic Trunking Protocol and, because of this, do not support dynamic trunking (dynamic desirable or auto). The only way to bring up a trunk between a router and a switch is by using the switchport mode trunk command.

Question 9

What parameter can be added to the end of a Cisco IOS ip route command to force its inclusion into the routing table, regardless of interface/next-hop status?&#10;A) permanent&#10;B) full&#10;C) Configure the AD to 0&#10;D) Configure the AD to 1

Accepted Answer

A) When used with the ip route command, the permanent keyword forces a static route into the routing table regardless of whether the associated interface goes down.

Question 10

The term IP routing refers explicitly to which of the following actions?&#10;A) Learning routes&#10;B) Dynamically establishing routes using IP protocols&#10;C) Forwarding packets&#10;D) Establishing protocols for routes

Accepted Answer

C) While the other actions are an important part of networking, IP routing is simply the action of forwarding packets.

Question 11

Which of the following is the first step a LAN-based host takes when a destination is NOT local?&#10;A) Find the destination host's MAC address.&#10;B) Encapsulate the IP packet in a data-link frame for the destination host.&#10;C) Find the default gateway's MAC address.&#10;D) Encapsulate the IP packet in a data-link frame for the default gateway.

Accepted Answer
