In a Hybrid topology, each node cooperates in the distribution of data in the network, combining features of different topologies.
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 process of modifying the source and destination IP addresses of IP packets during transit across a traffic routing device is known as __________.
- ARP (Address Resolution Protocol)
- DHCP (Dynamic Host Configuration Protocol)
- ICMP (Internet Control Message Protocol)
- NAT (Network Address Translation)
Network Address Translation (NAT) is the process of modifying the source and destination IP addresses of IP packets during transit across a traffic routing device.
An organization needs to implement a system to securely authenticate responses to DNS queries to prevent cache poisoning. What technology should they implement?
- DNS Over HTTPS (DoH)
- DNS Security Extensions (DNSSEC)
- DNS Cryptography
- DNS Spoofing
DNS Security Extensions (DNSSEC) is a technology used to secure DNS responses and prevent cache poisoning attacks.
To improve data transfer efficiency in WAN, _____ is a method that involves storing copies of frequently accessed data.
- Caching
- Encryption
- QoS
- Tunneling
To improve data transfer efficiency in WAN, caching is a method that involves storing copies of frequently accessed data.
For outdoor installations where cables are exposed to environmental elements, what type of cable is generally preferred?
- Coaxial Cable
- Direct Burial Cable
- Plenum Cable
- Twisted Pair Cable
Direct burial cables are generally preferred for outdoor installations where cables are exposed to environmental elements.
Which QoS mechanism is used to prioritize certain types of traffic over others?
- Weighted Fair Queuing (WFQ)
- First-Come, First-Served (FCFS)
- Last-In, First-Out (LIFO)
- Round Robin
Weighted Fair Queuing (WFQ) is a QoS mechanism used to prioritize certain types of traffic over others based on assigned weights.
_________ 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.
