________ is a WAN technology that prioritizes data packets based on labels instead of IP addresses.
- MPLS (Multiprotocol Label Switching)
- VPN (Virtual Private Network)
- DNS (Domain Name System)
- DHCP (Dynamic Host Configuration Protocol)
MPLS is a WAN technology that prioritizes data packets based on labels instead of IP addresses.
In which routing method are routing decisions made based on pre-determined, static routes that do not change unless manually updated?
- Default Routing
- Dynamic Routing
- Hybrid Routing
- Static Routing
In static routing, routing decisions are made based on pre-determined, static routes that do not change unless manually updated.
What is the difference between hard and soft QoS policies in terms of enforcement and flexibility?
- Hard QoS: Strict enforcement, less flexibility. Soft QoS: Flexible enforcement, more adaptability.
- Hard QoS: Flexible enforcement, more adaptability. Soft QoS: Strict enforcement, less flexibility.
- Hard QoS: Applied to voice traffic. Soft QoS: Applied to video traffic.
- Hard QoS: Priority for real-time applications. Soft QoS: Priority for non-real-time applications.
The difference between hard and soft QoS policies lies in their enforcement and flexibility. Hard QoS enforces strict rules with less flexibility, while soft QoS offers more adaptability.
What is the best practice for applying ACLs in a network to maximize efficiency and security?
- Apply ACLs as close to the source as possible
- Apply ACLs at the core layer
- Apply ACLs on distribution switches
- Apply ACLs on the perimeter router
The best practice is to apply ACLs as close to the source as possible to minimize unnecessary traffic on the network and maximize security.
Which tool is most commonly used for basic troubleshooting of WAN links?
- Ping
- Traceroute
- SNMP
- Nmap
Ping is commonly used for basic troubleshooting of WAN links as it helps verify connectivity and measure round-trip time.
The _______ time is the interval during which STP listens to and learns the network topology before transitioning to the forwarding state.
- Blocking
- Forwarding
- Learning
- Listening
The listening time in STP is the interval during which the protocol listens to and learns the network topology before transitioning to the forwarding state.
The process of adding a VLAN tag to frames on a trunk port is known as ________.
- VLAN Encapsulation
- VLAN Framing
- VLAN Tagging
- VLAN Untagging
The process of adding a VLAN tag to frames on a trunk port is known as VLAN Encapsulation.
A company is moving from password-based authentication to a more secure method for device access. Which technology should they consider implementing to improve security?
- VLANs
- TACACS+
- NAT
- ICMP
TACACS+ (Terminal Access Controller Access-Control System Plus) is a technology that provides secure authentication for device access, improving security over password-based authentication.
The integration of _________ in SDN allows for automated network management and orchestration.
- BGP
- SNMP
- Docker
- VLANs
The integration of SNMP (Simple Network Management Protocol) in SDN allows for automated network management and orchestration.
In QoS, ________ is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.
- Policing
- Shaping
- Queuing
- Guarantees
In Quality of Service (QoS), shaping is a mechanism that ensures a specific minimum level of bandwidth to a certain traffic class.
