EIGRP supports _________, which allows for more efficient use of network bandwidth and reduced routing update traffic.
- DUAL
- Equal Cost Multipath
- Route Summarization
- Split Horizon
EIGRP supports Equal Cost Multipath (ECMP), which allows for more efficient use of network bandwidth and reduced routing update traffic.
How does PPP handle network layer protocol multiplexing?
- Assigns Unique IP Addresses
- Uses Port Numbers
- Encapsulates Multiple Protocols
- Prioritizes Protocols
PPP handles network layer protocol multiplexing by encapsulating multiple protocols, allowing them to be transmitted over the same physical link.
Which protocol within IPSec is used to provide data integrity and authentication?
- AH (Authentication Header)
- ESP (Encapsulating Security Payload)
- IKE (Internet Key Exchange)
- SSL (Secure Sockets Layer)
The Authentication Header (AH) protocol within IPSec is used to provide data integrity and authentication.
What is a key disadvantage of using a star topology in very large networks?
- Complex Wiring
- High Maintenance Cost
- Limited Scalability
- Single Point of Failure
A key disadvantage of using a star topology in very large networks is limited scalability. As more devices are added, the central hub may become a bottleneck for data traffic.
In a network, _______ is used to connect segments of a LAN and contains logic to filter traffic based on MAC addresses.
- Hub
- Repeater
- Router
- Switch
In a network, a Switch is used to connect segments of a LAN and contains logic to filter traffic based on MAC addresses.
Which type of firewall uses a defined set of rules to decide whether to allow or block network traffic?
- Proxy firewall
- Stateful firewall
- Stateless firewall
- Application-layer firewall
A stateful firewall uses a defined set of rules to decide whether to allow or block network traffic based on the state of connections.
In DHCP, what mechanism is used to ensure that multiple DHCP servers do not offer conflicting IP addresses?
- DHCP Snooping
- DHCP Relay
- DHCP Failover
- DHCP Lease Renewal
DHCP Failover is used to ensure that multiple DHCP servers coordinate and do not offer conflicting IP addresses to clients, enhancing network reliability.
Which system is utilized for sending and storing log messages in a network, helping in network management and security?
- DHCP
- DNS
- Syslog
- HTTP
Syslog is a system used for sending and storing log messages in a network, aiding in network management and security.
A network administrator must design a QoS policy that dynamically adjusts priorities based on network load. Which advanced QoS feature should they consider?
- Class-Based Weighted Fair Queuing (CBWFQ)
- Low Latency Queuing (LLQ)
- Weighted Random Early Detection (WRED)
- AutoQoS
AutoQoS is an advanced QoS feature that dynamically adjusts priorities based on network load, providing an automated approach to QoS policy design.
For a business requiring remote access to servers in its private network from the internet, what NAT feature would be most appropriate to set up?
- Dynamic NAT
- PAT
- Port Forwarding
- Static NAT
Port Forwarding would be the most appropriate NAT feature for allowing remote access to servers in a private network from the internet, forwarding specific ports to internal servers.
