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 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.
________ 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.
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.
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.
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.
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.
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.
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.
_______ 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.
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.
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.
