A network administrator is tasked with improving the efficiency of a network that has grown complex over time with many specific routes. Which technique would be most effective?
- Dynamic Routing
- Route Aggregation
- Route Redistribution
- Static Routing
Route aggregation, also known as summarization, is an effective technique to improve the efficiency of a network with many specific routes by consolidating them into larger, summarized routes.
_____ is a technique used in WAN optimization to prioritize certain types of traffic.
- Quality of Service (QoS)
- Traceroute
- Bandwidth
- Latency
Quality of Service (QoS) is a technique used in WAN optimization to prioritize certain types of traffic.
________ is a Layer 2 security feature on switches that restricts the number of MAC addresses on a port.
- BPDU Guard
- Port Security
- PortFast
- VLAN Trunking
Port Security is a Layer 2 security feature on switches that restricts the number of MAC addresses on a port.
________ is a protocol used in AAA to provide centralized management of users for network devices.
- RADIUS
- SNMP
- ICMP
- LDAP
RADIUS is a protocol used in AAA to provide centralized management of users for network devices.
In ________, the data packets are encapsulated for transmission over a different network, providing security and privacy.
- MPLS (Multiprotocol Label Switching)
- VLAN (Virtual Local Area Network)
- NAT (Network Address Translation)
- SSL/TLS (Secure Sockets Layer/Transport Layer Security)
In MPLS (Multiprotocol Label Switching), the data packets are encapsulated for transmission over a different network, providing security and privacy by creating virtual private networks (VPNs).
In a scenario where a company requires efficient data transfer with error checking and flow control, which OSI layer plays a crucial role in meeting these needs?
- Data Link
- Physical
- Session
- Transport
The transport layer (Layer 4) is responsible for reliable data transfer, error checking, and flow control, making it crucial for meeting the company's requirements in this scenario.
How does VLSM differ from traditional fixed-length subnet masking?
- Traditional fixed-length subnet masking is more suitable for small networks, while VLSM is designed for large-scale networks
- Traditional fixed-length subnet masking provides more flexibility in address assignment than VLSM
- VLSM allows for variable-sized subnets within a network, while traditional fixed-length subnet masking uses a uniform subnet size
- VLSM is only applicable to IPv6, while traditional fixed-length subnet masking is used in IPv4 networks
VLSM (Variable Length Subnet Masking) allows for variable-sized subnets within a network, whereas traditional fixed-length subnet masking uses a uniform subnet size.
In QoS, ________ is used to ensure that no single traffic type consumes all available bandwidth.
- Traffic Shaping
- Bandwidth Policing
- Traffic Policing
- Congestion Management
Bandwidth Policing in QoS is used to ensure that no single traffic type consumes all available bandwidth.
What redundancy feature is often associated with chassis aggregation?
- GLBP (Gateway Load Balancing Protocol)
- HSRP (Hot Standby Router Protocol)
- VRRP (Virtual Router Redundancy Protocol)
- VSS (Virtual Switching System)
Chassis aggregation often involves technologies like Virtual Switching System (VSS) to provide redundancy and high availability by combining multiple physical switches into a single logical switch.
________ in QoS refers to the overall ability of the network to provide better service to selected network traffic.
- Classification
- Prioritization
- Bandwidth
- Congestion
In QoS, prioritization refers to the overall ability of the network to provide better service to selected network traffic.
