Which two statements regarding VRF tables are correct? (Choose two.)
A. A PE router’s VRF table stores routes received from directly connected CE devices.
B. A PE router’s VRF table stores routes received from its IGP from remote PE devices.
C. A PE router’s VRF table stores routes received from MP-BGP from remote PE devices.
D. A PE router’s VRF table stores routes received from all P and PE devices within the same AS.
When a PE device has a Layer 3 peering to a CE device it stores the routes received from the CE in a VRF to separate the routing information from other CE devices. PE to PE devices maintain a multi-protocol BGP (mpBGP / mBGP) peering.
Which two statements are correct about provider-provisioned Layer 3 VPNs? (Choose two.)
A. PE routers maintain forwarding tables for each customer VPN
B. PE routers offer a Layer 2 circuit to each CE device
C. PE routers and CE routers participate in conventional IP routing
D. PE routers exchange VPN traffic through their internal routing protocols
Question : 33
Which configuration parameter allows a Junos device to include an interface route into OSPF while prohibiting adjacencies from forming?
To include an interface route into OSPF as an internal OSPF route while prohibiting adjacency formation for that interface, you should include the interface under the [edit protocols ospf area area-number] hierarchy level along with the passive configuration option.
What is the default interval for a VRRP advertisement?
A. 1 second
B. 2 seconds
C. 10 seconds
D. 30 seconds
Which two values are used by an RSTP bridge to remove stale BPDU information? (Choose two.)
A. Message Age
B. Forwarding Delay
C. Hello Time
D. Max Age
RSTP uses the message age value in conjunction with the max age value to indicate a communication failure and to determine when to flush the MAC table. The message age is the number of seconds elapsed since the most recent BPDU was received. The maximum age timer specifies the maximum expected arrival tie of the hello BPDU. If the maximum age timer expires, the bridge detects that the link to the root bridge has failed and initiates a topology reconvergence.
In Q-in-Q tunneling, what is the purpose of the pop-swap operation?
A. pop the outer tag and swap the inner tag
B. pop and swap the inner tag
C. pop and swap both outer and inner tags
D. pop the inner tag and swap the outer tag
Which high availability feature is enabled by default on Junos devices?
A. nonstop active routing
B. root protection
C. nonstop forwarding
D. graceful Routing Engine switchover
What are two ways that nonstop routing works? (Choose two.)
A. by enabling redundant REs to switch from primary RE to backup RE
B. by alerting peer nodes of any routing table changes
C. by enabling redundant REs to run a different version of the Junos OS
D. by replicating routing protocol information
What are three ways that graceful Routing Engine switchover provides redundancy? (Choose three.)
A. by preserving interface and kernel information
B. by reducing time of RE failover
C. by preserving the data plane information
D. by preserving the control plane information
E. by not restarting the PFE
Using industry best practices, what is true regarding an external BGP session?
A. BGP neighbors belong to the same AS
B. BGP neighbors belong to a different AS
C. BGP sessions rely on a static route for reach ability
D. BGP sessions will be established between loopback interface addresses.
