Routing Flashcards
What does it mean of MULTILAYER SWITCH? IS IT A SWITCH AT L2?
Multilayer switch means Router because MULTILAYER means it can operate at different layers, like L2 and L3.
MULTILAYER SWITCH is a Router
SWITCH is an L2 Device
What is latency in networking?
a) The variation in the delay of packet delivery
b) The inconsistency in the rate of packet delivery
c) The time it takes for a transmission to reach the recipient
d) The measure of packet loss in a network
c) The time it takes for a transmission to reach the recipient
Problems with the timing and sequence of packet delivery are defined as latency and jitter.
Latency is the time it takes for a transmission to reach the recipient, measured in milliseconds (ms).
Jitter is defined as being a variation in the delay. Jitter manifests itself as an inconsistent rate of packet delivery.
What is jitter in networking?
a) The time it takes for a transmission to reach the recipient
b) The variation in the delay of packet delivery
c) The inconsistency in the rate of packet delivery
d) The measure of packet loss in a network
b) The variation in the delay of packet delivery
What is a default route in networking?
a) A dynamic route learned from neighboring routers
b) A route used for loopback testing
c) A special type of static route for unmatched destinations
d) A route used for multicast traffic
c) A special type of static route for unmatched destinations
How is the default route represented in IPv4?
a) 255.255.255.255
b) 0.0.0.0/0
c) 127.0.0.1
d) 192.168.0.1
Answer: b) 0.0.0.0/0 or
0.0.0.0 (IPv4) 0.0.0.0 (sbunet)
How is the default route represented in IPv6?
a) ::/1
b) ::1
c) ::/0
d) ::ffff:0:0
c) ::/0
What is the purpose of a default route?
a) To identify the next hop router for all traffic
b) To identify the next hop router for multicast traffic
c) To identify the next hop router for matched destinations
d) To identify the next hop router for unmatched destinations
d) To identify the next hop router for unmatched destinations
Port aggregation means:
combining two or more separate cabled links into a single logical channel.
Port aggregation is often implemented by the
Link Aggregation Control Protocol
(LACP)
port security configuration validates the
MAC address of end systems that
connect to a switch port
802.1x components
Supplicat (sfotware from a device)
Authenticator (nasa switch)
Authentication server (RADIUS or TACACS+
Most wireless LANs (WLANs) are based on the IEEE
802.11 standards, better
known by its brand name Wi-Fi. 802.11 standards define the physical layer media
by which data is encoded into a radio carrier signal by using a modulation scheme.
What advantage does the 2.4 GHz band have over the 5 GHz band?
c) Longer signal range through solid surfaces
