________ is a cloud computing service model where hardware, software, servers, storage, and network components are provided to the customer.
- IaaS (Infrastructure as a Service)
- PaaS (Platform as a Service)
- SaaS (Software as a Service)
- XaaS (Everything as a Service)
In IaaS (Infrastructure as a Service), all the essential components of cloud infrastructure are provided to the customer.
In QoS, what is the term used for the mechanism that limits the bandwidth used by certain types of traffic?
- Shaping
- Policing
- Queuing
- Dropping
Bandwidth shaping is the mechanism used in QoS to limit the bandwidth used by certain types of traffic.
Which routing protocol supports automatic summarization at classful network boundaries?
- BGP (Border Gateway Protocol)
- EIGRP (Enhanced Interior Gateway Routing Protocol)
- OSPF (Open Shortest Path First)
- RIP (Routing Information Protocol)
RIP supports automatic summarization at classful network boundaries, aggregating routes into a summarized form.
How does switch stacking impact the scalability of a network infrastructure?
- Decreases Scalability
- Depends on the Network Topology
- Increases Scalability
- No Impact on Scalability
Switch stacking increases scalability by allowing multiple physical switches to be managed as a single entity, simplifying network administration and expanding port density.
What is the purpose of using an extended access list in network configuration?
- To filter traffic based on source and destination IP addresses
- To control access to network resources with more granularity
- To provide basic packet filtering
- To prioritize network traffic based on applications
An extended access list allows for more granular control over network traffic, specifying detailed conditions for filtering.
What feature allows multiple physical switch ports to be bundled together as a single logical link for increased bandwidth and redundancy?
- Link Aggregation
- Port Mirroring
- VLAN Trunking
- Virtual Router Redundancy Protocol (VRRP)
Link Aggregation allows multiple physical switch ports to be bundled together as a single logical link, providing increased bandwidth and redundancy.
A network design requires a redundancy solution that allows for efficient utilization of multiple gateways without manual intervention for load distribution. What protocol should be implemented?
- HSRP (Hot Standby Router Protocol)
- VRRP (Virtual Router Redundancy Protocol)
- GLBP (Gateway Load Balancing Protocol)
- EIGRP (Enhanced Interior Gateway Routing Protocol)
HSRP is a Cisco proprietary protocol that provides default gateway redundancy and load balancing, allowing for efficient utilization of multiple gateways without manual intervention.
A company has expanded its network infrastructure to include multiple departments, each requiring different network segments for security and management purposes. What is the most efficient way to configure these segments?
- MPLS
- Subnetting
- VLAN
- VPN
VLANs (Virtual Local Area Networks) are the most efficient way to configure network segments, allowing different departments to be logically segmented for security and management purposes.
Which type of VPN would be most suitable for a user who frequently travels and needs secure access to the corporate network?
- Site-to-Site VPN
- Remote Access VPN
- MPLS VPN
- PPTP VPN
A Remote Access VPN is most suitable for a user who frequently travels and needs secure access to the corporate network from various locations.
An organization requires a secure way to connect remote workers to its central office. Which technology would provide a secure and cost-effective solution?
- VPN (Virtual Private Network)
- MPLS
- ISDN
- DSL
A VPN (Virtual Private Network) would provide a secure and cost-effective solution for connecting remote workers to the central office over the internet.
