In large networks, what is the primary advantage of using a bridge over a hub?
- Efficient Collision Domain Isolation
- Enhanced Security
- Increased Bandwidth
- Reduced Latency
In large networks, a bridge provides efficient collision domain isolation, reducing collisions and enhancing overall network performance.
In PPP, what mechanism is used for error detection and control at the data link layer?
- Cyclic Redundancy Check (CRC)
- Checksum
- Parity Bit
- Hamming Code
PPP uses Cyclic Redundancy Check (CRC) for error detection and control at the data link layer. CRC is a robust method for detecting errors in transmitted data.
What is route summarization primarily used for in networking?
- Allocating IP addresses
- Encrypting data in transit
- Load balancing traffic
- Minimizing the size of routing tables
Route summarization is primarily used to minimize the size of routing tables by representing a range of IP addresses with a single summary route.
To allow communication between VLANs, network administrators set up a ________, which routes traffic between different VLANs.
- Firewall
- Hub
- Router
- Switch
A router is used to route traffic between different VLANs, allowing communication between them.
What advanced feature differentiates a managed switch from an unmanaged switch in network configurations?
- Port Mirroring
- Power over Ethernet (PoE)
- Quality of Service (QoS)
- VLAN Support
VLAN support is an advanced feature that distinguishes a managed switch from an unmanaged switch, allowing for efficient network segmentation.
Which BGP attribute is used to define the preferred path in the absence of other decision factors?
- AS_PATH
- LOCAL_PREF
- NEXT_HOP
- WEIGHT
The LOCAL_PREF attribute in BGP is used to define the preferred path in the absence of other decision factors.
What specific technology is typically used to facilitate switch stacking?
- EtherChannel
- HSRP (Hot Standby Router Protocol)
- Stackwise
- VTP (VLAN Trunking Protocol)
Switch stacking is facilitated by technologies like Cisco Stackwise, which allows multiple switches to operate as a single logical unit.
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.
