What are three characteristics of multicast transmission? (Choose three.) A single packet can be sent to a group of hosts. Multicast messages map lower layer addresses to upper layer addresses. Multicast transmission can be used by routers to exchange routing information. Computers use multicast transmission to request IPv4 addresses. The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255.

A single packet can be sent to a group of hosts. Multicast messages map lower layer addresses to upper layer addresses. Multicast transmission can be used by routers to exchange routing information.

What is the protocol that is used to discover a physical address from a known logical address and what message type does it use?

ARP, broadcast

How does a Layer 3 switch differ from a Layer 2 switch? A Layer 3 switch learns the MAC addresses that are associated with each of its ports. However, a Layer 2 switch does not. A Layer 3 switch maintains an IP address table instead of a MAC address table. A Layer 3 switch supports VLANs, but a Layer 2 switch does not. An IP address can be assigned to a physical port of a Layer 3 switch. However, this is not supported in Layer 2 switches.

An IP address can be assigned to a physical port of a Layer 3 switch. However, this is not supported in Layer 2 switches.

Which two statements are correct in a comparison of IPv4 and IPv6 packet headers? (Choose two.) The Source Address field name from IPv4 is kept in IPv6. The Version field from IPv4 is not kept in IPv6. The Destination Address field is new in IPv6. The Header Checksum field name from IPv4 is kept in IPv6. The Time-to-Live field from IPv4 has been replaced by the Hop Limit field in IPv6.

Which sub-net includes 192.168.1.92 as usable host 192.168.1.96/27 192.168.1.128/25 192.168.1.128/28 192.168.1.192/29

The right answer is 192.168.1.128/25; i believe its because /25 enables you to create 2 networks with 126 hosts (+2 for broadcast and subnet address), and one of them has 192.168.1.92 on it.

A user calls the help desk to report that a Windows XP workstation is unable to connect to the network after startup and that a popup window says "This connection has limited or no connectivity." The technician asks the user to issue the ipconfig /all command. The user reports the IP address is 169.254.69.196 with subnet mask of 255.255.0.0 and nothing is displayed for the DNS server IP address. What is the cause of the problem? The DNS server IP address needs to be configured. The subnet mask was configured incorrectly. The workstation is unable to obtain an IP address from a DHCP server. The workstation NIC has malfunctioned.

The workstation is unable to obtain an IP address from a DHCP server.

A PC is configured to obtain an IP 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 entry refers to the PC itself. This entry maps to the default gateway. This is a static map entry. This is a dynamic map entry.
