A. Class A
B. Class B
C. Class C
D. Class D
Question 272
Which command configures an address of 192.168.1.1 with a mask of 255.255.255.0 on interface ge-0/0/0?
A. set ip interface ge-0/0/0 address 192.168.1.1 255.255.255.0
B. set ip interface ge-0/0/0 address 192.168.1.1/24
C. set interface ge-0/0/0 ip4 address 192.168.1.1 mask 255.255.255.0
D. set interfaces ge-0/0/0 unit 0 family inet address 192.168.1.1/24
The following configuration is sufficient to get a Fast Ethernet interface up and running. By default, IPv4 Fast Ethernet interfaces use Ethernet version 2 encapsulation.

Question 273
Which two protocols are connection-oriented? (Choose two.)
A. Ethernet
B. PPP
C. TCP
D. UDP
Point-to-Point Protocol (PPP) and Transmission Control Protocol (TCP) are a connection- oriented protocols. References: http://searchnetworking.techtarget.com/definition/connection-oriented
Question 274
Which statement is correct about the validate option when upgrading JUNOS software?
A. It will check the MD5 checksum of the install package.
B. It will check if the device meets the memory requirements for the install package.
C. It will check the compatibility of the configuration with the install package.
D. It will check if the device meets the storage requirement for the install package.
When you upgrade or downgrade Junos OS, we recommend that you include the validate option with the request system software add command to check that the candidate software is compatible with the current configuration. By default, when you add a package with a different release number, the validation check is done automatically.

Question 275
What are three advantages which dynamic routing protocols offer over static routing protocols? (Choose three.)
A. lower administrative overhead
B. increased network availability
C. greater network scalability
D. easier to implement qualified next hops
E. easier ECMP route implementation
Dynamic routing protocols help the network administrator manage the time-consuming and exacting process of configuring and maintaining static routes. Dynamic routing automatically adapts topology to reroute traffic if possible. Dynamic routing is generally independent of the network size.

Question 276
When troubleshooting ATM, which command would allow you to test reachability from one side of an ATM cloud to the other?
A. ping atm vci 0.100 interface at-0/1/0 end-to-end
B. ping atm vci 0.100 interface at-0/1/0 circuit
C. ping atm vci 0.100 interface at-0/1/0 far-end
D. ping atm vci 0.100 interface at-0/1/0 final-hop
Which command will display the temperature of the Routing Engine's CPU?
A. show chassis environment
B. show chassis routing-engine
C. show chassis temperatures
D. show chassis status
The output fields for theshow chassis routing-engine command include: * Temperature: Temperature of the air flowing past the Routing Engine. References: https://www.juniper.net/documentation/en_US/junos11.4/topics/reference/commandsummary/sho w-chassis-routing-engine.html
Question 278
Which commnand would correctly define a router's host-name?
A. # set ip host-name
B. > set ip host-name
C. # set system host-name
D. > set system host-name
Configure the hostname, using the set system host-name command. [edit] user@host# set system host-name newton-re0 References: http://www.juniper.net/techpubs/en_US/junos15.1/topics/example/router- namedomain-name-ip-address-system-id-configuring.html
Question 279
You have been asked to use a 28 bit subnet mask to segment the following network block: 108.12.5.0. How many usable hosts per sub-net could you create?
In Ethernet networks, duplex mismatches will lower performance. Which error statistics can be seen if a duplex mismatch is present?
A. collisions on the full-duplex side; runts on the half-duplex side
B. collisions on the full-duplex side; collisions on the half-duplex side
C. collisions on the half-duplex side; framing errors on the full-duplex side
D. collisions on the half-duplex side; giants on the full-duplex side
On an Ethernet connection, a duplex mismatch is a condition where two connected devices operate in different duplex modes, that is, one operates in half duplex while the other one operates in full duplex. References: https://en.wikipedia.org/wiki/Duplex_mismatch
