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.
What is the primary advantage of using GRE tunnels in conjunction with IPsec VPNs?
- GRE tunnels enhance IPsec VPN security by adding an extra layer of encryption.
- GRE tunnels simplify IPsec VPN configurations and reduce complexity.
- GRE tunnels provide tunneling capabilities, while IPsec VPNs handle encryption.
- There is no advantage to using GRE tunnels with IPsec VPNs.
GRE tunnels offer tunneling capabilities, allowing IPsec VPNs to focus on encryption, reducing complexity in the overall setup.
In an environment where data security is crucial, ________ cables are preferred for their resistance to eavesdropping and tapping.
- Coaxial
- Fiber optic
- HDMI
- Twisted pair
In environments where data security is crucial, fiber optic cables are preferred for their resistance to eavesdropping and tapping.
What is the primary function of Port Security in a network switch?
- Block all incoming traffic
- Control access to the network based on MAC addresses
- Encrypt data on the network
- Filter traffic based on IP addresses
The primary function of Port Security is to control access to the network based on MAC addresses, allowing only specified devices to connect.
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.
________ mechanisms in QoS help to avoid packet loss during high traffic periods by temporarily storing excess packets.
- Congestion Avoidance
- Traffic Shaping
- Packet Sniffing
- Bandwidth Policing
Congestion Avoidance mechanisms in QoS help to avoid packet loss during high traffic periods by temporarily storing excess packets.
