Which of the following is IANA responsible for?
The Internet Assigned Numbers Authority (IANA) is responsible for managing the global IP address pool, along with:
Allocating blocks of IP addresses to Regional Internet Registries (RIRs) such as ARIN (North America), RIPE NCC (Europe), APNIC (Asia-Pacific), etc.
Managing autonomous system numbers (ASNs).
Overseeing DNS root zones and protocol parameters.
IANA does not assign IPs directly to enterprises or individuals --- those tasks are delegated to RIRs and ISPs.
Option A & B: Enterprises and residential allocations are handled by ISPs or RIRs.
Option D: North American IPs are managed by ARIN, not IANA.
Option C is correct -- IANA manages the global IP address allocation hierarchy.

Which of the following statements about the OSPF routing protocol is FALSE?
OSPF (Open Shortest Path First) is a Link-State protocol that uses:
Cost (based on bandwidth) as its metric.
Dijkstra's algorithm to compute shortest path trees.
Supports hierarchical routing with areas (e.g., Area 0 as backbone).
Routers exchange LSAs, not full routing tables.
Option D is FALSE -- OSPF does not use hop-count. That's a RIP (Distance Vector) feature.
Nokia IP Routing Guide -- Section: ''OSPF Operation and Area Design''
RFC 2328 -- OSPFv2 Protocol Specification
Which of the following statements about MD-CLI is FALSE?
A. It allows atomic transactions. B. Configuration changes are activated when the running configuration datastore is saved to a file. C. To achieve transactional configuration, it is necessary to have multiple configuration datastores. D. Multiple users may enter the global configuration mode concurrently.
The Model-Driven Command Line Interface (MD-CLI) in Nokia SR OS provides a structured and programmatic way to manage configurations. It is based on a transactional model, meaning changes are made in a candidate configuration before being committed to the running configuration.
Let's review each statement:
Nokia SR OS MD-CLI User Guide
Nokia SRA Study Guide -- Chapter: 'Model-Driven Configuration and Transactions'
Which of the following types of information is used to calculate the Shortest Path Tree (SPT)?
The Shortest Path Tree (SPT) is calculated by Link-State routing protocols like OSPF and IS-IS using:
A complete map of the network topology.
Each router uses algorithms like Dijkstra's to compute the shortest paths to all destinations.
Option C is correct -- full network topology is used.
Option A refers to Distance Vector methods.
Option B and D are results of topology analysis but not the input used.
Nokia Routing Protocols Guide -- Section: ''SPT and Link-State Behavior''
RFC 2328 -- OSPF Specification
Which of the following is a function of the Link layer?
The Link layer, also known as the Data Link layer in the OSI model, is responsible for encapsulating packets from the Network layer into frames suitable for transmission over the physical medium. This process includes adding headers and trailers to the packet to create a frame, which contains necessary information for error detection, addressing, and control.
According to the OSI model, the Data Link layer serves as the intermediary between the Network layer and the Physical layer. It ensures that data is packaged into frames and manages the access to the physical transmission medium.
Option A correctly describes this function.
Option B pertains to the Network layer, which is responsible for encapsulating data into IP datagrams and determining the routing of these datagrams across networks.
Option C relates to the Transport layer, which handles the encapsulation of application data into transport layer segments, such as TCP or UDP messages.
Option D is a function of the Physical layer, which deals with the transmission and reception of raw bitstreams over a physical medium, including the timing and synchronization of signals.
