QUESTION 38
You are asked to connect an IP phone and a user computer using the same interface on an EX Series switch.

Which statement is correct about graceful Routing Engine switchover (GRES)?

128.0.0.1

172.23.11.10

QUESTION 46
You want to use filter-based forwarding (FBF) on your Internet peering router to load-balance traffic to two directly connected ISPs based on the source address.
Which two statements are correct in this scenario? (Choose two.)

FBF uses the no-forwarding routing instance type.

FBF uses the forwarding routing instance type.

RIB groups are used to copy routes from the inet. o routing table.

RIB groups are used to hide routes in the inet. 0 routing table.

QUESTION 47
Two routers share the same highest priority and start time.

In this situation, what is evaluated next when determining the designated router? The router with the lowest router ID become the DR.

The router with the highest router ID becomes the DR

The routers perform another DR election.

The router with the highest MAC address become the DR

QUESTION 48
You are configuring an IS-IS IGP network and do not see the IS-IS adjacencies established. In this scenario, what are two reasons for this problem? (Choose two.)

MTU is not at least 1492 bytes.

IP subnets are not a /30 address.

The Level 2 routers have mismatched areas.

The lo0 interface is not included as an IS-IS interface.

QUESTION 49
Which two mechanisms are part of building and maintaining a Layer 2 bridge table? (Choose two.)

blocking

flooding

learning

listening

QUESTION 50
You want to ensure traffic is routed through a GRE tunnel.
In this scenario, which two statements will satisfy this requirement? (Choose two.)

Tunnel endpoints must have a route that directs traffic into the tunnel.

All intermediary devices must have a route to the tunnel endpoints.

Keepalives must be used on stateless tunneling protocols.

BFD must be used on the stateless tunneling protocols.

QUESTION 51
You have two OSPF routers forming an adjacency. R1 has a priority of 32 and a router ID of 192.168.1.2. R2 has a priority of 64 and a router ID of 192.168.1.1. The routers were started at the same time and all other OSPF settings are the default settings.
Which statement is correct in this scenario?

At least three routers are required for a DR/BDR election

Router IDs must match for an adjacency to form.

R2 will be the BDR.

R1 will be the BDR.

QUESTION 52
Which statement about aggregate routes is correct?

Aggregate routes can only be used for static routing but not for dynamic routing protocols.

Aggregate routes are automatically generated for all of the subnets in a routing table.

Aggregate routes are always preferred over more specific routes, even when the specific routes have a better path.

Aggregate routes are used for advertising summarized network prefixes.
