- A PC is configured to obtain an IPv4 address automatically from network 192.168.1.0/24. The network administrator issues the arp -a command and notices an entry of 192.168.1.255 ff-ff-ff-ff-ff-ff. Which statement describes this entry?
This is a static map entry.
This is a dynamic map entry.
This entry refers to the PC itself.
This entry maps to the default gateway.

What addresses are mapped by ARP?
IPv4 address to a destination MAC address
Destination IPv4 address to the source MAC address
Destination IPv4 address to the destination host name
ipv4 add to a destination MAC address
When an IPv4 packet is sent to a host on a** remote network,** what information is provided by ARP?
The IPv4 address of the destination host
The MAC address of the router interface closest to the sending host
The MAC address of the switch port that connects to the sending host
- What is the purpose of ARP in an IPv4 network?
To forward data onward based on the destination IP address
done
To obtain a specific MAC address when an IP address is known
To forward data onward based on the destination MAC address.
- mac address of the router closest to the sending host
- to obtain a mac address
- Company policy requires using the most secure method to safeguard access to the privileged exec and configuration mode on the routers. The privileged exec password is trustknow1. Which of the following router commands achieves the goal of providing the highest level of security?
enable password trustknow1
service password-encryption
enable secret trustknow1
- What is the purpose of the startup configuration file on a Cisco router?
To facilitate the basic operation of the hardware components of a device
done
To contain the commands that are used to initially configure a router on startup
To contain the configuration commands that the router IOS is currently using
- enable secret trustknow1
- to contain the commands r used to initially configure a router on starup
- Which characteristic describes the default gateway of a host computer?
The logical address of the router interface on the same network as the host computer
The physical address of the switch interface connected to the host computer
The physical address of the router interface on the same network as the host computer
The logical address assigned to the switch interface connected to the router
2. A technician is configuring a router to allow for all forms of management access. As part of each different type of access, the technician is trying to type the command login. Which configuration mode should be entered to do this task?
User executive mode
Global configuration mode

Privileged EXEC mode
- The logical address of the router interface on the same network as the host computer
- any line
- whaat is the purpose of setting a default gateway on a router?
To assign IP addresses to local devices
To provide a fallback IP address
To block incoming traffic

- Which two definitions accurately** describe the associated application layer** protocol? (Choose two.)
SMTP – transfers web pages from web servers to clients
Telnet – provides remote access to servers and networking devices
DNS – resolves Internet names to IP addresses
FTP – transfers email messages and attachments
HTTP – enables devices on a network to obtain IP addresse
2. What is a function of the tracert command that differs** from the ping** command when they are used on a workstation?
The tracert command reaches the destination faster.
The tracert command shows the information of routers in the path.
The tracert command sends one ICMP message to each hop in the path.
telnet and dns
2. tracert shows the info of routers in the path
