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 IPv6, the ________ address is used for multicast traffic to communicate with multiple devices simultaneously.
- Anycast
- Unicast
- Broadcast
- Multicast
In IPv6, the Multicast address is used for multicast traffic to communicate with multiple devices simultaneously.
What distinguishes VRRP from HSRP in terms of configuration and deployment?
- VRRP uses a virtual MAC address while HSRP uses a real MAC address.
- VRRP is a Cisco proprietary protocol, and HSRP is an industry standard.
- VRRP allows for load balancing, while HSRP does not.
- VRRP has a higher priority range than HSRP.
VRRP distinguishes itself from HSRP by using a virtual MAC address during configuration and deployment.
In BGP, the ______ attribute determines the shortest path to a destination network.
- AS Path
- Next Hop
- Local Preference
- Weight
In BGP, the AS Path attribute determines the shortest path to a destination network.
An enterprise wants to enhance its network security through granular control of network traffic. Which aspect of SDN would be most beneficial?
- OpenFlow
- Southbound API
- Northbound API
- Network Virtualization
OpenFlow, as part of SDN, allows granular control of network traffic by defining how packets are forwarded through network devices, enhancing security measures.
