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.
In switch stacking, what role does the master switch play?
- Backup Configuration
- Centralized Management
- Forwarding Traffic Only
- Redundancy Only
In switch stacking, the master switch plays a role in centralized management, overseeing the operation and configuration of the entire stack.
In a scenario where an organization has a limited number of IP addresses but requires several small networks, how should the subnetting be designed?
- Classful Subnetting
- Classless Subnetting
- Supernetting
- Variable Length Subnet Masking (VLSM)
Variable Length Subnet Masking (VLSM) is the appropriate subnetting technique for designing subnets of various sizes, conserving IP addresses for small networks.
EtherChannel can be implemented using either _______ or _______ as the control protocol.
- LACP
- PAgP
- STP
- VTP
EtherChannel can be implemented using either PAgP (Port Aggregation Protocol) or LACP (Link Aggregation Control Protocol) as the control protocol.
What type of NAT maps multiple private IP addresses to a single public IP address using different ports?
- Dynamic NAT
- NAPT (Network Address Port Translation)
- PAT (Port Address Translation)
- Static NAT
PAT (Port Address Translation) maps multiple private IP addresses to a single public IP address using different ports for differentiation.
________ 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.
In a high-traffic network environment, a network engineer is tasked with improving bandwidth and redundancy. Which approach would they most likely consider?
- Load Balancing
- Quality of Service (QoS)
- Subnetting
- VLAN Segmentation
The network engineer would most likely consider implementing load balancing to improve bandwidth and redundancy in a high-traffic environment. Load balancing distributes network traffic across multiple paths, optimizing resource utilization.
