Q321. Which three features does GETVPN support to improve deployment and scalability? (Choose three.)
A. configuration of multiple key servers to work cooperatively
B. allowing traffic to be discarded until a group member registers successfully
C. local exceptions in the traffic classification ACL
D. GDOI protocol configuration between group members and the key server
E. redundant IPsec tunnels between group members and the key server
F. redundant multicast replication streaming through the use of a bypass tunnel
Q322. Refer to the exhibit.
A spoke site that is connected to Router-A cannot reach a spoke site that is connected to Router-B, but both spoke sites can reach the hub. What is the likely cause of this issue?
A. There is a router doing PAT at site B.
B. There is a router doing PAT at site A.
C. NHRP is learning the IP address of the remote spoke site as a /32 address rather than a /24 address.
D. There is a routing issue, as NHRP registration is working.
If one spoke is behind one NAT device and another different spoke is behind another NAT device, and Peer Address Translation (PAT) is the type of NAT used on both NAT devices, then a session initiated between the two spokes cannot be established.

Q323. Which two statements about OSPF default route injection are true? (Choose two.)
A. The ABR requires manual configuration to send a default route into an NSSA area.
B. The ABR injects a default route into a Totally Stub Area.
C. In a stub area, the ASBR generates a summary LSA with link-state ID 0.0.0.0.
D. If the default route is missing from the routing table, the ASBR can use the default-information originate command to advertise the default into the OSPF domain.
E. By default, OSPF normal areas will generate default routes into the routing domain if a default route exists.
Q324. DRAG DROP
Drag and drop the router preference on the left to the correct routing sequence (from most preferred to least preferred) on the right.
Q325. Refer to the exhibit.
NHRP registration is failing; what might be the problem?
A. invalid IP addressing
C. incorrect NHRP mapping
D. incorrect NHRP authentication
Configuring an authentication string ensures that only routers configured with the same string can communicate using NHRP. Therefore, if the authentication scheme is to be used, the same string must be configured in all devices configured for NHRP on a fabric

Q326. Refer to the exhibit.
If a port is configured as shown and receives an untagged frame, of which VLAN will the untagged frame be a member?
A. VLAN 1
B. VLAN 2
C. VLAN 3
D. VLAN 4
When typing: Switch(config-if)#switchport mode?
access Set trunking mode to ACCESS unconditionally
dynamic Set trunking mode to dynamically negotiate access or trunk mode
trunk Set trunking mode to TRUNK unconditionally
Switch(config-if)#switchport mode dynamic?
auto Set trunking mode dynamic negotiation parameter to AUTO
desirable Set trunking mode dynamic negotiation parameter to DESIRABLE
So if we configure Fa0/1 as dynamic auto mode, it will not initiate any negotitation but waiting for the other end negotiate to be a trunk with DTP. If the other end does not ask it to become a trunk then it will become an access port. Therefore when using the “show interface fastEthernet0/1 switchport” command we will see two output lines “ Administrative Mode. dynamic auto” and “Operational Mode. static access” Note. To set this port to VLAN 2 as the output above just use one additional command. “switchport access vlan 2”.
Now back to our question, from the output we see that Fa0/1 is operating as an access port on VLAN 2 so if it receive untagged frame it will suppose that frame is coming from VLAN 2.
Q327. Refer to the exhibit.
R1 is performing mutual redistribution, but OSPF routes from R3 are unable to reach R2. Which three options are possible reasons for this behavior? (Choose three.)
A. R1 requires a seed metric to redistribute RIP.
B. The RIP version supports only classful subnet masks.
C. R1 is filtering OSPF routes when redistributing into RIP.
D. R3 and R1 have the same router ID.
E. R1 and R3 have an MTU mismatch.
F. R2 is configured to offset OSPF routes with a metric of 16.
A. RIP requires a seed metric to be specified when redistributing routes into that protocol. A seed metric is a "starter metric" that gives the RIP process a metric it can work with. The OSPF metric of cost is incomprehensible to RIP, since RIP's sole metric is hop count. We've got to give RIP a metric it understands when redistributing routes into that protocol, so let's go back to R1 and do so.
C. Filtering routes is another explanation, if the routes to R2 are boing filtered from being advertised to R1.
F. If the metric is offset to 16, then the routes will have reached the maximum hop count when redistributed to RIP. The max hop count for RIP is 16.
Q328. Which two statements about Layer 2 Frame Prioritization bits are true? (Choose two.)
A. 802.1Q frame headers carry the CoS value in the three most-significant bits of the 2-byte Tag Control Information field.
B. ISL frame headers carry an IEEE 802.1P CoS value in the three least-significant bits of the 2-byte User field.
C. ISL frame headers carry an IEEE 802.1P CoS value in the three most-significant bits of the 1-byte User field.
D. On 802.1Q trunks, traffic in the native VLAN is carried in 802.1Q frames.
E. Only 802.1Q and ISL frame types can carry CoS information.
F. On 802.1Q trunks, traffic in the native VLAN is carried in 802.1P frames.
Q329. Refer to the exhibit.
Which BGP feature allows R1 to instruct R2 which prefixes it is allowed to advertise to R1?
A. route refresh
B. Prefix-Based Outbound Route Filtering
C. distribute lists
D. prefix lists
Q330. As a best practice, when a router is configured as an EIGRP Stub, which routes should be received from its distribution neighbor?
A. the default route
B. static routes
C. internal routes only
D. internal and external routes
Stub routing is commonly used in a hub and spoke network topology. In a hub and spoke network, one or more end (stub) networks are connected to a remote router (the spoke) that is connected to one or more distribution routers (the hub). The remote router is adjacent only to one or more distribution routers. The only route for IP traffic to follow into the remote router is through a distribution router. This type of configuration is commonly used in WAN topologies where the distribution router is directly connected to a WAN. The distribution router can be connected to many more remote routers. Often, the distribution router will be connected to 100 or more remote routers. In a hub and spoke topology, the remote router must forward all nonlocal traffic to a distribution router, so it becomes unnecessary for the remote router to hold a complete routing table. Generally, the distribution router need not send anything more than a default route to the remote router.
