You have made configuration changes to your Cisco device. Now you want to save the changes to use the next time the device is booted up. Which command could you use?
flash start copy
copy run start
run copy start
copy start tftp
An internet server has a single network interface that has been assigned an IP address. The server is running both the FTP and HTTP services. A client computer initiates a session with the HTTP server. How is the HTTP request from the client routed to the correct service running on the server?
IP address
Sequence number
Port or socket number
Routing Information Protocol (RIP)
Session ID
While working at the console of a Cisco device, you need to view a list of the commands that are available in the current mode. Which command should you use?
?
terminal history
terminal editing

What is the first thing that happens when a collision occurs on an Ethernet network?
A) A device that wants to send data sends a request to send (RTS) message.
B) All devices wait a random amount of time before trying to retransmit.
C) The device that detected the collision transmits a jam signal.
D) All devices that were sending data transmit a clear to send (CTS) message.
E) Devices listen to the medium before trying to retransmit.
How does TCP handle data sequencing?
TCP does not sequence the data; it simply passes numbered segments created at a higher layer in the sequence defined.
TCP breaks user data into segments, numbers each segment, places them in the correct sequence, and sends each one in order, waiting for an acknowledgement before sending the next segment.
TCP breaks user data into segments, numbers each segment, and sends each segment in order, without waiting for an acknowledgement.
TCP breaks the data into segments, numbers each segment, and passes them to UDP, which sequences the segments into the correct order.
You are working on a Cisco device. The prompt is showing Router#. Which mode are you in?
ROMmon
Privileged EXEC
Global Configuration
User EXEC
Jaden is the network engineer at a branch office. There are non-Cisco devices on the network that Jaden would like to make sure are discovered by the Cisco router. Jaden has just enabled the Link Layer Discovery Protocol (LLDP) on the router. Which of the following is true about LLDP?
Enabled by default.
Does not need to be enabled globally before being used.
Uses the same commands as CDP.
Configured on a per-interface basis.
What role does ARP play in the routing process?
If a router does not know a destination device's IP address, it sends an ARP broadcast containing the destination device's MAC address and requesting its IP address.
If a router does not know a destination device's MAC address, it sends an ARP broadcast containing the destination device's IP address and requesting its MAC address.
If a router knows the MAC and IP address of a destination host, it sends an ARP request to update the other routers' route tables.
ARP does not play any role in the routing process. Switches use ARP to map IP addresses to MAC addresses in collision domains.
What is the purpose of a network model?
Standardize processes at each layer.
Provide the logical addressing required to locate your destination node.
Used to remotely access application on remote systems.
Provide an interface for submitting web requests.
Which of the following commands would you use to modify the CDP packet exchange interval to send CDP packets every 30 seconds?
cdp timer 30
cdp holdtime 30
cdp interval 30
cdp exchange 30
cdp broadcast 30
The process of breaking a message into packets, adding control information and other information, and then transmitting the message through the transmission medium is known as ________?
Transformation
Encapsulation
Sequencing
Segmentation
During network transmission, data is transferred to various routers, which forward the data to the appropriate network. If the source and destination network addresses reside on the same network, which protocol is used to determine the MAC address of the destination IP address?
HTTP get
TCP
ARP
UDP
What is the maximum cable length for UTP Ethernet T implementations?
10 kilometers
100 meters
40 kilometers
300 meters
You are a field technician for a large company. You have been sent to a remote site to troubleshoot a downed router. When you arrive at the remote site, how will you connect your laptop to the router?
Connect the laptop's COM/USB port to the router's Ethernet port using a straight-through cable.
Connect the laptop's COM/USB port to the router's console port using a crossover cable.
Connect the laptop's COM/USB port to the router's console port using a rollover cable.
Connect the laptop's COM/USB port to the router's console port using a straight-through cable.
What term does the OSI model use that is different from the TCP/IP model uses to refer to frame, packet, and segment?
Protocol data unit (PDU)
Session
IEEE Ethernet standard
Presentation
You have been put in charge of connecting two company networks that were previously separated. You need to connect a 100BaseTx Ethernet network with an older token ring network. Most traffic will be localized within each network, with only a little traffic crossing between networks. Both networks are using the TCP/IP protocol suite. Which connectivity device would be the best choice in this situation?
Bridge
Hub
Switch
Router
The configuration register runs during the POST. What does it control?
What is stored in NVRAM.
How the router boots up.
The licensing information.
The running-config file.
While working at the console of a Cisco device, you need to view a list of the commands that are currently stored in the history buffer of the system. Which command should you use?
terminal no history
?
terminal editing
terminal history

You want to prevent collisions on your network by creating separate collision domains and defining virtual LANs. Which of the following devices should you choose?
Bridge
Active hub
Switch
Router
You have a small network with two switches, SwitchA and SwitchB. MDI-X is not enabled on either switch. Each switch has three client computers connected. IP addresses have been assigned to various devices as follows: WrkA_1, WrkA_2, and WrkA_3 are connected to SwitchA, while WrkB_4, WrkB_5, and WrkB_6 are connected to SwitchB. All of the devices are configured to operate within the same subnet. You need to connect SwitchA and SwitchB so that workstations connected to SwitchA can communicate with workstations connected to SwitchB. What should you do?
Connect SwitchA and SwitchB using a straight-through cable.
Connect SwitchA and SwitchB to a router using a straight-through cable on each side.
Connect SwitchA and SwitchB using a crossover cable.
Connect SwitchA and SwitchB to a router using a crossover cable on each side.
As specified in the Ethernet standards, what is the maximum number of hosts supported on a single subnet?
254
100
512
1024
