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.
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.
How does BGP prevent routing loops in inter-domain routing?
- Split Horizon
- Route Poisoning
- Route Aggregation
- AS_PATH
In BGP, the AS_PATH attribute is used to prevent routing loops in inter-domain routing by tracking the path that the route has traversed.
In what scenario would static routing be more secure compared to dynamic routing?
- Dynamic routing is always more secure than static routing.
- In a scenario where the network topology is stable and predictable, static routing can be more secure than dynamic routing.
- Security is not a consideration in routing protocols.
- Static routing is always more secure than dynamic routing.
In scenarios with a stable and predictable network topology, static routing can be more secure as it reduces the attack surface by not dynamically exchanging routing information.
