Chapter 5 Exam
4. Which two statements describe features or functions of the logical link control sublayer in Ethernet standards? (Choose two.)
1.The data link layer uses LLC to communicate with the upper layers of the protocol suite. 2Logical link control is implemented in software.
15. Refer to the exhibit. A switch with a default configuration connects four hosts. The ARP table for host A is shown. What happens when host A wants to send an IP packet to host D?
Host A sends out a broadcast of FF:FF:FF:FF:FF:FF. Every other host connected to the switch receives the broadcast and host D responds with its MAC address.
3. What statement describes Ethernet?
It defines the most common LAN type in the world.
13. The ARP table in a switch maps which two types of address together?
Layer 3 address to a Layer 2 address
19. Fill in the blank. A collision fragment, also known as a
Runt
17. Which statement describes the treatment of ARP requests on the local link?
They must be forwarded by all routers on the local network.
5. What statement describes a characteristic of MAC addresses?
They must be globally unique.
11. What is auto-MDIX?
a feature that detects Ethernet cable type
16. Refer to the exhibit. The switches are in their default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which network hosts will receive the ARP request sent by host A?
only hosts B, C, and router R1
20. Fill in the blank. On a Cisco switch,______
port-based
21. Fill in the blank. ARP _____ is a technique that is used to send fake ARP messages to other hosts in the LAN. The aim is to associate IP addresses to the wrong MAC addresses.
spoofing
8. What addressing information is recorded by a switch to build its MAC address table?
the source Layer 2 address of incoming frames
