You are configuring BGP policies for a site with a dual-homed connection as shown in the exhibit. You must ensure that inbound traffic from Internet hosts flow through the ISP A connection.
Which statement is correct in this scenario?
- A . Apply a BGP export policy on R1 to assign a lower MED value to routes advertised to ISP A
- B . Apply a BGP export policy on R1 to assign a higher local preference value to routes advertised to ISP A
- C . Apply a BGP export policy onR2to assign a lower origin value to routes advertised to ISP B
- D . Apply a BGP export policy to R2 to prepend [65001 65001 65001 65001 65001] to the AS path of routes advertised to ISP B
You are redistributing static routes into an OSPF area.
Which two statement are true is this scenario? (Choose two.)
- A . The external route advertisements have a domain scope.
- B . The area must be stub area.
- C . The area must be the backbone area.
- D . The routes can be advertised in type 7 LSAs.
Exhibit.
A router is attempting to form an OSPF neighborship with another router. However, the OSPF neighborship fails to establish completely.
Referring to the exhibit, what is the problem?
- A . There is an OSPF area mismatch
- B . There is an interface MTU mismatch
- C . There is an interface subnet mask mismatch
- D . There is an interface type mismatch
Which statement is correct about MSTP?
- A . MSTP enables mapping multiple independent spanning tree instances onto one physical topology
- B . MSTP enables dynamic discovery of Layer 2 neighbors.
- C . MSTP dynamically manages VLAN registration in a LAN
- D . MSTP uses slacked VLAN tags to extend a Layer 2 Ethernet connection between multiple sites
You have an IPv4 multicast network configured as PIM-SM.
What must be done before replacing your static RP with auto-RP?
- A . Enable sparse-dense mode on each of the routers in the network.
- B . Configure auto-RP domains on each router in the network.
- C . Configure each router in the network as a candidate BSR.
- D . Enable each router in the network to forward multicast packets.
You are enabling MSTP in your Layer 2 network to prevent loops.
In this scenario, which three parameters must match on all switches in the network? (Choose three. )
- A . configuration name
- B . bridge priority
- C . MSTI-to-VLAN mapping
- D . max age
- E . revision level
which protocol is a multicast routing protocol?
- A . OSPF
- B . BGP
- C . PIM
- D . IS-IS
You are asked to deploy 802.1X on your EX Series switches. You need to ensure authenticated devices continue to have access to the network even if the authentication server fails.
Which action meets this configuration objective?
- A . Configure the server fail fallback with a value of sustain.
- B . Set the reauthentication interval to a value of 0.
- C . Configure the static MAC bypass for the authentication server.
- D . Set the reauthentication interval to a value of disable.
Click the Exhibit button.
The policy shown in the exhibit is applied as an export policy to your BGP neighborship.
Which action will be taken for route 12.233.45.5?
- A . It will be evaluated by the next policy.
- B . It will be accomplished by term 1.
- C . It will be accepted by term 1.
- D . It will be rejected by term 2.
- E . It will be accepted by the default policy
You are using 802.1X in your access network consisting of EX Series switches. You recently had a failure with your RADIUS server which resulted in authenticating client devices being denied access to the network. You want to change this behavior so that authenticating clients are directed to a remediation VLAN.
Which RADIUS server failback setting satisfies this requirement?
- A . permit
- B . move
- C . sustain
- D . deny
