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.
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.
