_________ is a method in QoS that dynamically adjusts the priority of different traffic types based on network conditions.
- Policing
- Shaping
- Queuing
- Classification
In QoS, classification is a method that dynamically adjusts the priority of different traffic types based on network conditions.
In complex network environments, ________ is used to reduce the risk of VLAN hopping attacks.
- VLAN Access Control
- VLAN Pruning
- VLAN Segmentation
- VLAN Trunking
VLAN Access Control is used in complex network environments to reduce the risk of VLAN hopping attacks.
BGP uses the _______ attribute to identify the originating Autonomous System of a route.
- AS Path
- Origin
- Next Hop
- Local Preference
BGP uses the Origin attribute to identify the originating Autonomous System of a route.
The process of encapsulating data with necessary protocol information at each OSI layer is known as _______.
- Encapsulation
- Fragmentation
- Framing
- Segmentation
The process of encapsulating data with necessary protocol information at each OSI layer is known as encapsulation.
To prevent unauthorized access, a network administrator can configure _______ on switch ports.
- Port Security
- Routing Protocol
- Subnet Masking
- VLAN Trunking
To prevent unauthorized access, a network administrator can configure Port Security on switch ports.
In an IPv4 network, what is the primary reason for implementing CIDR (Classless Inter-Domain Routing)?
- To improve security by assigning unique IP addresses to each device.
- To overcome the limitations of the traditional class-based IP addressing scheme and efficiently allocate IP addresses.
- To reduce the size of the routing tables and slow down the growth of the global routing table.
- To simplify subnetting and make it easier for administrators to manage IP address assignments.
CIDR is implemented in IPv4 networks to overcome the limitations of the traditional class-based IP addressing scheme and efficiently allocate IP addresses.
Which type of DNS record is used to translate domain names into IP addresses?
- A Record
- CNAME Record
- PTR Record
- MX Record
An A Record (Address Record) is used to translate domain names into IP addresses.
What is the impact of configuring PortFast on a switch port connected to an end device?
- Allows the port to immediately transition to the forwarding state
- Binds the MAC address to the switch port
- Disables spanning tree on the port
- Enables rapid spanning tree convergence
Configuring PortFast on a switch port connected to an end device allows the port to immediately transition to the forwarding state, eliminating the delay introduced by spanning tree protocol.
The ________ header in IPv6 is used to ensure efficient routing and handling of packets.
- Fragment
- Hop-by-Hop Options
- Routing
- Extension
The Hop-by-Hop Options header in IPv6 is used to ensure efficient routing and handling of packets.
How does a VLAN Trunking Protocol (VTP) assist in managing VLANs across multiple switches?
- It allows switches to negotiate VLAN information
- It assigns VLANs dynamically
- It encrypts VLAN information
- It limits the number of VLANs per switch
VTP assists in managing VLANs across multiple switches by allowing switches to negotiate VLAN information automatically.
