________ is a Cisco protocol that ensures high availability by providing a single virtual IP address and multiple gateways for load balancing.
- HSRP (Hot Standby Router Protocol)
- OSPF (Open Shortest Path First)
- VRRP (Virtual Router Redundancy Protocol)
- GLBP (Gateway Load Balancing Protocol)
GLBP (Gateway Load Balancing Protocol) is a Cisco protocol that ensures high availability by providing a single virtual IP address and multiple gateways for load balancing.
_________ in cloud computing refers to the distribution of network resources to ensure optimal balance and performance.
- Load Balancing
- Scalability
- Virtualization
- Redundancy
Load balancing in cloud computing involves distributing network resources to ensure optimal balance and performance.
In configuring a network that supports both IPv4 and IPv6, what is a key consideration for ensuring seamless communication between different IP version hosts?
- Dual-Stack Configuration
- Port Forwarding
- Tunneling
- VLAN Configuration
Tunneling is a key consideration for ensuring seamless communication between different IP version hosts in a network supporting both IPv4 and IPv6. Tunneling encapsulates IPv6 packets within IPv4 packets for transmission.
Which feature in switch configuration allows for assigning multiple ports to a single broadcast domain?
- Port mirroring
- STP
- Trunking
- VLAN
Virtual LANs (VLANs) in switch configuration allow for assigning multiple ports to a single broadcast domain, improving network segmentation and management.
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.
_______ is a technique used in GRE tunnels to maintain a consistent network path and avoid fragmentation.
- MTU Path Discovery
- Spanning Tree Protocol
- Subnetting
- HSRP
MTU Path Discovery is a technique used in GRE tunnels to maintain a consistent network path and avoid fragmentation.
How does SNMPv3 differ from SNMPv1 and SNMPv2 in terms of security features?
- Community strings for authentication
- Addition of HMAC for message integrity
- Plain text communication
- Encryption of SNMP packets
SNMPv3 introduces the addition of HMAC for message integrity, enhancing security compared to SNMPv1 and SNMPv2.
When designing a BGP network for a large organization, what factor should be considered to ensure optimal route propagation and stability?
- Convergence Time
- Route Summarization
- BGP Confederations
- Prefix Length
Route summarization should be considered when designing a BGP network for a large organization to ensure optimal route propagation and stability. It helps reduce the number of BGP routes.
BGP is classified as which type of routing protocol?
- Dynamic Routing
- Interior Gateway Protocol (IGP)
- Exterior Gateway Protocol (EGP)
- Link-State Routing
BGP is classified as an Exterior Gateway Protocol (EGP), as it is designed to route between different Autonomous Systems (AS) on the Internet.
