In subnetting, what does the term CIDR stand for and what is its significance?
- Centralized IP Distribution and Routing; It simplifies the management of IP addresses
- Classful IP Dynamic Routing; It enhances dynamic routing capabilities
- Classless Inter-Domain Routing; It allows for more efficient allocation of IP addresses and routing
- Continuous IP Data Routing; It ensures constant data flow within subnets
CIDR stands for Classless Inter-Domain Routing, and its significance lies in allowing more efficient allocation of IP addresses and routing.

- Blocking
- Permitting
- Denying
- Filtering
In firewall settings, the term "Permitting" refers to allowing specific traffic through based on defined criteria.
In high-availability network designs, _________ is a feature that allows for multiple switches to be managed as a single unit.
- GLBP (Gateway Load Balancing Protocol)
- HSRP (Hot Standby Router Protocol)
- StackWise
- VRRP (Virtual Router Redundancy Protocol)
In high-availability network designs, StackWise is a feature that allows for multiple switches to be managed as a single unit.
______ routing protocols, such as OSPF and EIGRP, adjust automatically to network changes, providing redundancy and fault tolerance.
- Adaptive
- Convergent
- Dynamic
- Static
Dynamic routing protocols, such as OSPF and EIGRP, adjust automatically to network changes, providing redundancy and fault tolerance.
Efficient IP address allocation in VLSM requires careful ________ planning.
- Address
- Host
- Network
- Subnet
Efficient IP address allocation in VLSM requires careful subnet planning.
Which DHCP message is used by a client to accept an IP address offered by a DHCP server?
- DHCPREQUEST
- DHCPDISCOVER
- DHCPACK
- DHCPNAK
The DHCPREQUEST message is used by a client to accept an IP address offered by a DHCP server during the DHCP negotiation process.
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.
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.
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.
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.
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.
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.
