In IPv6, ________ addresses are used to send packets to a group of interfaces.
- Anycast
- Broadcast
- Multicast
- Unicast
In IPv6, multicast addresses are used to send packets to a group of interfaces. Multicast enables efficient communication to multiple hosts.
Which IPv6 address type is equivalent to IPv4’s private addressing and is used for local communications within a network segment?
- Global Unicast
- Link-Local
- Multicast
- Unique Local
Unique Local IPv6 addresses are equivalent to IPv4's private addressing and are used for local communications within a network segment.
In OSPF, what is the purpose of the designated router (DR) in a broadcast network?
- Elects the router responsible for exchanging routing information with routers in other areas.
- Facilitates efficient communication in broadcast networks by reducing the number of adjacencies.
- Handles the redistribution of external routes into the OSPF routing domain.
- Manages the distribution of routing updates within the OSPF area.
The designated router (DR) in OSPF broadcast networks is responsible for facilitating efficient communication by reducing the number of adjacencies and managing the exchange of routing information.
DHCP _________ is a feature that allows network administrators to reserve specific IP addresses for certain devices.
- Snooping
- Relay
- Reservations
- Superscope
DHCP Reservations is a feature that allows network administrators to reserve specific IP addresses for certain devices.
A _________ NAT policy allows an external user to access a server within a private network by using a pre-defined public IP address.
- Dynamic NAT
- NAT Overload
- PAT (Port Address Translation)
- Static NAT
A Static NAT policy allows an external user to access a server within a private network by using a pre-defined public IP address.
In a chassis aggregation setup, _________ is a common feature that enhances data traffic management between switches.
- ACL
- Multicast
- QoS
- VLAN
In a chassis aggregation setup, Quality of Service (QoS) is a common feature that enhances data traffic management between switches.
________ operate at the network layer and are responsible for making decisions based on IP addresses to forward packets to their destination.
- Bridges
- Hubs
- Routers
- Switches
Switches operate at the network layer and make decisions based on IP addresses to forward packets to their destination.
What is the primary difference between IPv6 and IPv4 addressing in terms of address length?
- 128 bits
- 256 bits
- 32 bits
- 64 bits
IPv6 addresses are 128 bits long, which is a significant increase from IPv4's 32-bit addresses.
Which topology uses a hybrid approach, combining elements of both star and bus topologies for improved performance?
- Bus
- Hybrid
- Mesh
- Star
A hybrid topology combines elements of both star and bus topologies for improved performance. It offers the advantages of both topologies.
What version of SNMP provides message integrity, authentication, and encryption for secure management of network devices?
- SNMPv1
- SNMPv2c
- SNMPv3
- SNMPv4
SNMPv3 (Simple Network Management Protocol version 3) provides message integrity, authentication, and encryption for secure management of network devices.
