_____ provides a secure CLI session with encryption to Cisco Switch.
An SSH connection
A network tech is attempting to configure an interface. He enters the command : SanJose(config)# ip address 192.169.2.1 255.255.255.0 . Why is the command rejected by the device?
The command is being entered from the wrong mode of operation.
On which switch interface would an adminstrator configure an IP address so that the switch can be managed remotely?
VLAN 1
What protocol is respondisble for controlling the size of segments and the rate at which segments are exchanged between a web client and a web server?
TCP
Which name is assigned to the transport layer PDU?
Segment
A network engineer is measuring the transfer of bits across the company backbone for a mission critical database app. The engineer notices the network throughput appearing lower than the bandwidth expected. Which three factors would influence the differences in throughput? (Answers Three)
- The amount of traffic that is currently crossing the network.
- The type of traffic that is crossing the network.
- The latency that is created by the number of network devices that the data is corssing.
What is a characteristic of the LLC sublayer?
It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media.
What method is used to manage contention-based access on a wireless network?
-CSMA/CA
What are the three primary functions provided by Layer 2 data encapsulation? Choose three.
- Data link layer addressing
- Detection of errors through CRC calculations
- Delimiting groups of bits into frames
What will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address?
It will discard the frame
Which frame forwarding method receives the entire frame and performs a CRC check to detect errors before forwarding the frame?
Store - and - Forward switching
What addresses are mapped by the ARP?
Destination MAC address to a Destination IPv4 address.
What information is added during encapsulation at OSI Layer 3?
Source and Destination ip address
What are two services provided by the OSI network layer? Choose two
- Routing packets towards the destination
- Encapsulating PDUs from the transport layer
What are the three characteristics of multicast transmission?
- A single packet can be sent to a group of hosts.
- Multicast transmission can be used by routers to exchange routing information.
- Routers will not forward multicast addresses in the range from 224.0.0.0 to 224.0.0.255
