What is the first step that a switch performs during the bootup sequence?
After a Cisco switch is powered on, it goes through the following boot sequence:
- First, the switch loads a power-on self-test (POST) program stored in ROM.
- Next, the switch loads the boot loader software.
- The boot loader performs low-level CPU initialization.
What is a possible cause of runt Ethernet frames when a switch is being used?
What is a possible cause of runt Ethernet frames when a switch is being used? A runt frame is a frame that is smaller than 64 bytes, the minimum allowed Ethernet frame. This type of frame is usually due to a malfunctioning NIC or excessive collisions. Duplex misconfiguration can cause connectivity issues.
Which configuration must be in place for the Auto-MDIX feature to function on a switch interface group of answer choices?
Which configuration must be in place for the auto-MDIX feature to function on a switch interface? The speed and duplex of the interface must be configured for auto detect.
How can DHCP packets be used to threaten a switched LAN?
How can DHCP packets be used to threaten a switched LAN? Numerous DHCP requests are sent to the DHCP server from spoofed hosts, causing the DHCP address pool to become depleted. This type of attack is known as DHCP starvation.
What are the steps to configure a switch?
- Step 1: Inspect your hardware. Check the model number of your shiny new switch.
- Step 2: Set up management IP.
- Step 3: Check VTP revision number.
- Step 4: Configure access ports.
- Step 5: Configure trunk ports.
- Step 6: Configure access ports.
- Step 7: Set up VTY line config.
What file does boots switch use?
The startup-config file is stored in flash memory and contains the configuration that the switch loads when booting. During a switch boot, running-config is replaced by startup-config. Changes to running-config that are not copied to startup-config are lost when the system reboots.
What is the Auto-MDIX feature on a switch quizlet?
What is the auto–MDIX feature? – It enables a device to automatically configure an interface to use a straight-through or a crossover cable. – It enables a device to automatically configure the duplex settings of a segment.
What is the Auto-MDIX feature on a switch?
The auto–MDIX enables a switch to use a crossover or a straight-through Ethernet cable to connect to a device regardless of the device on the other end of the connection.
Which three fields are found in an 802.3 Ethernet frame choose three?
Which three fields are found in an 802.3 Ethernet frame? (Choose three.) Answers Explanation & Hints: The fields of an Ethernet frame are the preamble, destination and source address, length, data, and FCS.
Which information does a switch use to keep the MAC address table information current?
Explanation: To maintain the MAC address table, the switch uses the source MAC address of the incoming packets and the port that the packets enter. The destination address is used to select the outgoing port.
Which type of traffic requires a separate VLAN strict QoS requirements and a one way overall delay of less than 150 ms across the network?
The acronym voip describes the type of traffic that requires a separate VLAN, strict QoS requirements, and a one–way overall delay less than 150 ms across the network. These restrictions help to ensure traffic quality.
What is the effect of issuing the BranchSw enable command to configure a new Cisco 2960 switch?
A technician is configuring a new Cisco 2960 switch. What is the effect of issuing the BranchSw(config-if)# duplex full command? It automatically adjusts the port to allow device connections to use either a straight-through or a crossover cable. It configures the switch as the default gateway.
What is the reason for giving a Layer 2 switch an IP address?
Explanation:A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address.
Why are routers needed in networking group of answer choices?
Why are routers needed in networking? One of the basic functions of a router is to connect different networks. Each interface on a router belongs to a different network. LAN devices can be connected through switches.
Which two files are loaded into RAM by the router when it boots choose two?
Which two files are loaded into RAM by the router when it boots? (Choose two.) A router loads the IOS image file and startup configuration file into RAM when it boots. Then the startup configuration file is copied into RAM as the running configuration file.
