最新的 JNCIS-ENT JN0-352 免費考試真題:
1. Click the Exhibit button. A network includes several autonomous systems that exchange routing information using BGP. Multiple BGP routes exist for the same prefix. Referring to the exhibit, which attribute would BGP use first when selecting a preferred route?
A) MED
B) local preference
C) origin type
D) AS path length
2. Your ISP is announcing a default route to both R1 and R2. You want your network routers to forward all Internet traffic through the R1 device.
Which BGP attribute would you use?
A) next-hop
B) MED
C) local preference
D) origin
3. A GRE tunnel is experiencing fragmentation issues. You confirm that the tunnel is up and is functioning correctly. You confirm that hosts are sending 1500-byte packets. In this scenario, which statement is correct?
A) You should use the clear-dont-fragment parameter to allow fragmentation.
B) You should enable BFD to more rapidly identify tunnel link failures.
C) You should lower the physical interface's MTU to 1476 bytes to avoid fragmentation.
D) You should use ToS copying to reduce header size.
4. Which two types of tunnels are able to be created on all Junos devices? (Choose two.)
A) GRE
B) IP-IP
C) STP
D) IPsec
5. You deployed a new EX Series switch with DHCP snooping enabled and you do not see any entries in the snooping databases for an interface. Which two Juniper configurations for that interface caused this issue? (Choose two.)
A) Dynamic ARP inspection is enabled on the interface.
B) The interface is configured as a disabled port.
C) The interface is configured as a trunk port.
D) MAC limiting is enabled on the interface.
