What is a primary disadvantage of dynamic routing compared to static routing in terms of resource usage?
- Dynamic routing consumes fewer resources as it dynamically adjusts to network changes.
- Dynamic routing protocols require more resources, such as bandwidth and processing power, compared to the simplicity of static routing.
- Resource usage is similar for both dynamic and static routing.
- Static routing consumes more resources due to the manual configuration of routes.
Dynamic routing, due to its continuous exchange of routing information, demands more resources, including bandwidth and processing power, compared to the more static nature of static routing.
Which protocol is commonly used for VLAN tagging on trunk links in a Cisco environment?
- 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.
A ________ VPN enables the connection of separate corporate sites over the internet as if they were one network.
- 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.
Which type of cable is commonly used for short-distance Ethernet networks due to its affordability and ease of installation?
- Coaxial Cable
- Fiber Optic Cable
- HDMI Cable
- Twisted Pair
Twisted pair cables are commonly used for short-distance Ethernet networks due to their affordability and ease of installation.
In Cisco routers, what is the implicit rule at the end of every ACL?
- Allow all
- Deny all
- Deny any
- Permit any
In Cisco routers, the implicit rule at the end of every ACL is to deny any traffic that has not been explicitly permitted.
When designing a network for a multinational corporation with various branch offices and data centers, which technique is essential to manage the routing tables effectively?
- Border Gateway Protocol (BGP)
- Multi-Protocol Label Switching (MPLS)
- Route Summarization
- Virtual Private Networks (VPNs)
Route summarization is essential when designing a network for a multinational corporation with various branch offices and data centers to manage the routing tables effectively, reducing the size and complexity of routing information.
