When configuring redistribution on a router, what is a common challenge that network engineers must address?
- Duplicate IP addresses
- Inconsistent metrics
- Route summarization
- Routing loops
A common challenge in redistribution is dealing with inconsistent metrics between different routing protocols, which can impact the selection of optimal routes.
Which layer of the OSI model is responsible for error checking and reliable packet delivery?
- Data Link
- Network
- Physical
- Transport
The Transport Layer in the OSI model is responsible for error checking and reliable packet delivery.
What is the primary function of a network switch in a LAN environment?
- Amplifying signals
- Assigning IP addresses
- Forwarding data between devices
- Routing between networks
The primary function of a network switch in a LAN environment is to forward data between devices within the same network.
The _______ protocol allows for one virtual router to act as a default gateway, backed up by a second router in case the primary fails.
- HSRP (Hot Standby Router Protocol)
- OSPF (Open Shortest Path First)
- VRRP (Virtual Router Redundancy Protocol)
- BGP (Border Gateway Protocol)
The HSRP (Hot Standby Router Protocol) allows for one virtual router to act as a default gateway, backed up by a second router in case the primary fails.
What feature allows multiple physical switch ports to be bundled together as a single logical link for increased bandwidth and redundancy?
- Link Aggregation
- Port Mirroring
- VLAN Trunking
- Virtual Router Redundancy Protocol (VRRP)
Link Aggregation allows multiple physical switch ports to be bundled together as a single logical link, providing increased bandwidth and redundancy.
A network design requires a redundancy solution that allows for efficient utilization of multiple gateways without manual intervention for load distribution. What protocol should be implemented?
- HSRP (Hot Standby Router Protocol)
- VRRP (Virtual Router Redundancy Protocol)
- GLBP (Gateway Load Balancing Protocol)
- EIGRP (Enhanced Interior Gateway Routing Protocol)
HSRP is a Cisco proprietary protocol that provides default gateway redundancy and load balancing, allowing for efficient utilization of multiple gateways without manual intervention.
A company has expanded its network infrastructure to include multiple departments, each requiring different network segments for security and management purposes. What is the most efficient way to configure these segments?
- MPLS
- Subnetting
- VLAN
- VPN
VLANs (Virtual Local Area Networks) are the most efficient way to configure network segments, allowing different departments to be logically segmented for security and management purposes.
Which type of VPN would be most suitable for a user who frequently travels and needs secure access to the corporate network?
- Site-to-Site VPN
- Remote Access VPN
- MPLS VPN
- PPTP VPN
A Remote Access VPN is most suitable for a user who frequently travels and needs secure access to the corporate network from various locations.
An organization requires a secure way to connect remote workers to its central office. Which technology would provide a secure and cost-effective solution?
- VPN (Virtual Private Network)
- MPLS
- ISDN
- DSL
A VPN (Virtual Private Network) would provide a secure and cost-effective solution for connecting remote workers to the central office over the internet.
In ______, the active virtual gateway (AVG) assigns a virtual MAC address to each member of the GLBP group.
- HSRP
- GLBP
- VRRP
- OSPF
In GLBP (Gateway Load Balancing Protocol), the active virtual gateway (AVG) assigns a virtual MAC address to each member of the GLBP group.
