Question 1

Exhibit

user@router> show route 192.168.100.2

inet.O: 15 destinations, 17 routes (15 active, 0 holddown, 0 hidden) Limit/Threshold: 1048576/1048576 destinations

+ = Active Route, - = Last Active, * = Both 192.168.100.2/32 *[OSPF/IO] 00:14:29, metric 1

> to 172.16.1.6 via ge-0/0/1.0 [BGP/170] 00:06:49, localpref 100

AS path: 65102 I, validation-state: unverified > to 172.16.1.6 via ge-0/0/1.0

Referring to the exhibit, which statement is correct?

AThe BGP path is the only active route.

BThe BGP route is preferred over the OSPF route.

CThe OSPF path is the only active route.

D/ Traffic is load-balanced across two routes.

Answer : C

Referring to the exhibit, the presence of the '+' symbol next to the OSPF route for 192.168.100.2/32 indicates that this is the active route being used to forward traffic. The BGP route, although present, does not have the '+' symbol, indicating it is not the active route. In Junos OS, the routing table displays the active route with a '+' symbol, and the fact that the OSPF route has this symbol means it is the preferred path based on the routing protocol's decision process, which takes into account factors such as route preference (administrative distance) and metrics.

Question 2

What are two attributes of the UDP protocol? (Choose two.)

AUDP is more reliable than TCP.

BUDP is always slower than TCP.

CUDP is best effort.

DUDP is connectionless.

Answer : C, D

UDP (User Datagram Protocol) is known for being connectionless (D) and providing best-effort delivery without the reliability mechanisms present in TCP (C). This means that UDP does not establish a connection before sending data and does not guarantee delivery, order, or error checking, making it faster but less reliable than TCP.

Question 3

What are two physical interface properties? (Choose two.)

AMAC address

BIP address

Crouting protocols

DMTU

Answer : A, D

Two physical interface properties in Junos OS include the MAC address (A) and the Maximum Transmission Unit (MTU) size (D). The MAC address is a hardware identifier for the network interface, while the MTU size determines the largest packet size that the interface can transmit without needing to fragment the packet.

Question 4

Which service does RADIUS provide?

Arouting

Bauthentication

CDNS resolution

Dtime synchronization

Answer : B

RADIUS, which stands for Remote Authentication Dial-In User Service, provides authentication services for users trying to access a network. It is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

Question 5

You issue the monitor traffic interface ge-0/0/0 command.

What will this command accomplish?

AIt displays real-time statistics for interface ge-0/0/0.

BIt displays an operational summary of ge-0/0/0.

CIt displays the MTU and MAC address for ge-0/0/0.

DIt displays a packet capture on interface ge-0/0/0.

Answer : D

The command 'monitor traffic interface ge-0/0/0' (D) initiates a packet capture on the specified interface, allowing you to view the actual packets being transmitted and received. This is useful for troubleshooting and analyzing the traffic passing through the interface in real time.

Question 6

You have logged on to a Junos device and are at the operational mode prompt.

Which two commands are used at this prompt? (Choose two.)

Ashow interface ge-0/0/0

Brequest system shutdown

Cset interface ge-0/0/0 unit 0 family inet

Drun show interface terse

Answer : A, B

At the operational mode prompt on a Junos device, you can use various commands to view the device's status and request system operations. The show interface ge-0/0/0 command is used to display information about a specific interface, while the request system shutdown command is used to properly shut down the device. The set command is used in configuration mode, not operational mode, and the run command is used to execute operational mode commands from configuration mode.

Question 7

Exhibit

[edit system archival] user@router# show configuration {

transfer-on-commit; archive-sites {

"scp://user@172.15.100.2 : /archive" password ## SECRET-DATA

"ftp://user@10.210.9.178:/archive" password "$9..."; ## SECRET-DATA

Referring to the exhibit, where are the configuration backup files stored?

AFiles are stored to the SCP site and the FTP site in a round-robin manner.

BFiles are stored to the SCP site and the FTP site simultaneously.

CFiles are stored to any site as selected by Junos internally.

DFiles are stored to the SCP site but if the transfer fails, then to the FTP site.

Answer : B

In Junos OS, the archival configuration under [edit system] allows for the automatic backup of configuration files to designated locations upon commit. When multiple archive-sites are specified, as shown in the exhibit with both SCP and FTP sites listed, the device does not choose between them or use them in a round-robin manner. Instead, it attempts to transfer the configuration backup files to all specified sites simultaneously upon each commit. This ensures redundancy and increases the likelihood that a backup will be successfully stored even if one of the transfer methods or destinations fails.
