When troubleshooting a WAN connection, which protocol is essential for testing network reachability and round-trip time?
- ICMP
- SNMP
- TCP
- UDP
ICMP (Internet Control Message Protocol) is essential for testing network reachability and round-trip time when troubleshooting a WAN connection.
BGP peers exchange routing information through the ________ process.
- Synchronization
- Update
- Convergence
- Negotiation
BGP peers exchange routing information through the Update process.
How does IPv6 address the issue of broadcast traffic in networks, which is prevalent in IPv4?
- By eliminating broadcast communication and using multicast and anycast for efficient communication.
- By increasing the broadcast domain size to accommodate more devices.
- By introducing a new broadcast protocol specifically designed for IPv6.
- By limiting the number of devices in a network to reduce broadcast traffic.
IPv6 addresses the issue of broadcast traffic by eliminating broadcast communication and using multicast and anycast for efficient communication.
In a scenario with multiple VLANs, how does inter-VLAN routing occur?
- Through Layer 2 switches
- Through VLAN tunneling
- Using VLAN trunks
- Via a router or Layer 3 switch
Inter-VLAN routing occurs through a router or Layer 3 switch, which routes traffic between different VLANs.
What technique is used in VLSM to avoid IP address exhaustion?
- ARP (Address Resolution Protocol)
- CIDR (Classless Inter-Domain Routing)
- DHCP (Dynamic Host Configuration Protocol)
- NAT (Network Address Translation)
CIDR (Classless Inter-Domain Routing) is the technique used in VLSM to avoid IP address exhaustion by allowing the allocation of address blocks with variable lengths, matching the actual network requirements.
A company is experiencing network congestion issues between its distribution and access layers. How can EtherChannel be effectively deployed to address this problem?
- By aggregating multiple links into a logical bundle to increase bandwidth
- By configuring static IP routes to improve packet forwarding
- By disabling spanning-tree protocol to eliminate redundant paths
- By implementing VLAN trunking to isolate traffic
EtherChannel can be effectively deployed by aggregating multiple links into a logical bundle to increase bandwidth and address network congestion issues between the distribution and access layers.
How does a switch learn the MAC addresses of the devices connected to it?
- ARP requests
- DHCP leases
- IP addressing
- MAC flooding
A switch learns the MAC addresses of devices connected to it by examining the source MAC address of incoming frames and associating them with the corresponding port.
What is the maximum data transmission speed supported by Category 6 (Cat6) Ethernet cables?
- 1 Gbps
- 1 Tbps
- 10 Gbps
- 100 Gbps
Category 6 (Cat6) Ethernet cables support a maximum data transmission speed of 10 Gbps.
What is the main advantage of using LACP (Link Aggregation Control Protocol) over PAgP (Port Aggregation Protocol) in EtherChannel configuration?
- LACP provides standards-based compatibility
- LACP supports dynamic negotiation with non-Cisco devices
- PAgP is more efficient in high-traffic environments
- PAgP is the only option for Layer 3 EtherChannels
The main advantage of LACP is its standards-based compatibility, allowing dynamic negotiation with devices from different vendors.
A network engineer is configuring a network that needs a large number of IP addresses. Which IP version should they consider for an ample supply of addresses?
- IPX
- IPv4
- IPv5
- IPv6
IPv6 is designed to provide an ample supply of IP addresses, making it suitable for networks requiring a large number of addresses.
