JN0-106 sample questions

Question 1

A corporate enterprise has been allocated the IPv4 network block 192.168.10.0/24. The network engineering team must segment this block to support six new departments.

Each department must have its own dedicated subnet. The largest department has 25 host devices that require IP addresses, while the others have fewer. The engineering team wants to use a single fixed-length subnet mask (FLSM) for all departments to simplify routing and management.

Which subnet mask should the team apply to meet the requirements while minimizing wasted IP addresses, and how many usable hosts will be available per subnet?

Accepted Answer

A /27 mask, providing 30 usable hosts per subnet

Answer

A /28 mask, providing 14 usable hosts per subnet

Answer

A /29 mask, providing 6 usable hosts per subnet

Answer

A /26 mask, providing 62 usable hosts per subnet

Question 2

When a host on an Ethernet network needs to send data to another host on the same local subnet but only knows the destination's IPv4 address, which TWO of the following statements accurately describe the address resolution process? (Select TWO)

Accepted Answer

The target device responds with an ARP reply sent as a unicast message directly to the requester.

Accepted Answer

The host sends an ARP request as a Layer 2 broadcast.

Answer

The target device responds with an ARP reply sent as a broadcast message to update all local ARP caches.

Answer

The host uses ND (Neighbor Discovery) with ICMPv4 to resolve the address.

Answer

The host sends an ARP request to the default gateway's MAC address.

Question 3

A Junos device receives a packet destined for the IP address 10.1.5.50. The routing table contains multiple active routes that encompass this destination. Based on the longest match routing principle, which of the following routes will the router select to forward the packet?

Accepted Answer

10.1.5.0/24 via ge-0/0/2

Answer

0.0.0.0/0 via ge-0/0/3

Answer

10.0.0.0/8 via ge-0/0/0

Answer

10.1.0.0/16 via ge-0/0/1

Question 4

True or False: Transmission Control Protocol (TCP) is an example of a connectionless protocol because it relies on the underlying IP layer to establish the path before data transmission begins.

Accepted Answer

False

Answer

True

Question 5

During a network assessment, you need to configure an interface with an IP address that ends with the decimal value 192 in the last octet. What is the correct binary representation of the decimal number 192?

Accepted Answer

11000000

Answer

10100000

Answer

11100000

Answer

10000000

Question 6

In the Junos OS software architecture, which component is strictly responsible for maintaining routing protocols, managing chassis components, and providing the user interface?

Accepted Answer

The Routing Engine (RE)

Answer

The modular chassis backplane

Answer

The Packet Forwarding Engine (PFE)

Answer

The ASIC microcode
