Nt1310 Unit 1 Question Paper
CCNA 3 - Module 4 Exam Answers
1 Which statements are true concerning the shared memory buffering used by an Ethernet switch? (Choose two.)
* Frames are processed through a single queue.
* All frames are placed in a common memory buffer.
• Frames are placed in a queue for the destination port.
• A port with a full memory buffer can cause frames for available ports to be delayed.
• Each switch port is statically assigned a buffer of equal size.
2 What are the functions of routers? (Choose three.)
• improving network performance by increasing latency by twenty to thirty percent
* segmenting broadcast domains
* forwarding packets based on destination network layer addresses
* segmenting collision domains
• forwarding packets as …show more content…
CSMA/CD token passing
CSMA/CA

14 Which two statements are valid planning considerations for WLAN deployments? (Choose two.)
The IEEE 802.11n draft standard is intended to improve WLAN data rates and range without requiring additional power or RF band allocation.
In North America, 802.11a channels should be restricted to 1, 6, and 11 to reduce channel overlaps.
An ESS generally includes a common SSID to allow roaming from access point to access point without requiring client configuration.
802.1q trunking across the network infrastructure allows an ESS to associate diverse access points as long as each access point has a unique SSID.
Cells in an ESS should have 10 to 15 percent overlap between them in an extended service area.
Access points can be quickly deployed as ad hoc installations to form an ESS.
