- 802.1Q
- ARP
- ICMP
- STP
The 802.1Q protocol is commonly used for VLAN tagging on trunk links in a Cisco environment.
How does a VLAN improve network security and performance?
- By connecting devices in a flat network structure
- By eliminating the need for routers
- By increasing broadcast traffic
- By reducing broadcast traffic
VLANs improve network security and performance by reducing broadcast traffic, isolating broadcast domains, and enhancing network segmentation.
Which of the following IPv6 features eliminates the need for Network Address Translation (NAT)?
- DHCPv6
- Port Forwarding
- Stateless Address Autoconfiguration (SLAAC)
- Subnetting
SLAAC eliminates the need for NAT in IPv6 by allowing devices to autoconfigure their addresses without manual intervention.

- Remote Access
- Site-to-Site
- SSL
- PPTP
A Site-to-Site VPN enables the connection of separate corporate sites over the internet as if they were one network.
What is the role of 'queueing' in Quality of Service?
- Prioritizing packets based on IP addresses
- Buffering and managing the flow of packets
- Filtering unwanted network traffic
- Controlling the speed of data transmission
In Quality of Service (QoS), 'queueing' involves buffering and managing the flow of packets, allowing for the prioritization of certain traffic and ensuring efficient data transmission.
Which layer of the OSI model do GRE tunnels operate at?
- Data Link Layer
- Network Layer
- Transport Layer
- Application Layer
GRE tunnels operate at the Network Layer of the OSI model, providing a mechanism for encapsulating a variety of network layer protocols.

Twisted pair cables are commonly used for short-distance Ethernet networks due to their affordability and ease of installation.
Which routing protocol is classful and does not support VLSM or CIDR?
- EIGRP
- OSPF
- RIP
- RIPv1
RIPv1 (Routing Information Protocol version 1) is a classful routing protocol that does not support Variable Length Subnet Masking (VLSM) or Classless Inter-Domain Routing (CIDR).
