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.
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.
Which layer of the OSI model is responsible for error checking and reliable packet delivery?
- Data Link
- Network
- Physical
- Transport
The Transport Layer in the OSI model is responsible for error checking and reliable packet delivery.
What is the primary function of a network switch in a LAN environment?
- Amplifying signals
- Assigning IP addresses
- Forwarding data between devices
- Routing between networks
The primary function of a network switch in a LAN environment is to forward data between devices within the same network.
The _______ protocol allows for one virtual router to act as a default gateway, backed up by a second router in case the primary fails.
- HSRP (Hot Standby Router Protocol)
- OSPF (Open Shortest Path First)
- VRRP (Virtual Router Redundancy Protocol)
- BGP (Border Gateway Protocol)
The HSRP (Hot Standby Router Protocol) allows for one virtual router to act as a default gateway, backed up by a second router in case the primary fails.
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.
